[0075] The record and playback device 1 may additionally be connectable to a wired network 11. [0076] The record and playback device 1 may be connected to the mobile terminal 8, to the content provider 3, to the Internet (not shown), to other content sources (not shown) and/or to other record and playback devices 1′ (FIG. 30) via the wired network 11 or the PLMN wireless network 10. [0000] Record and Playback Device 1 [0077] Referring to FIG. 2, the record and playback device 1 is shown in more detail. [0078] The record and playback device 1 includes an input 12, front-end circuitry 13, a demultiplexer 14, a filter 15 and a system bus 16. The front-end circuitry 13 usually includes a tuner (not shown), an analogue-to digital converter (not shown), a demodulator (not shown) and an error correction module (not shown). A descrambler (not shown) may also be included. [0079] The record and playback device 1 includes a central processing unit (CPU) 17, memory 18 and storage 19. At least one computer program 20 is used to control operation of record and playback device 1 illustrated in FIG. 2. [0080] The storage 19 is in the form of a hard disk drive. However, other types of storage can be used, such as an optical disk drive or solid-state memory. The storage 19 may comprise plural devices and may include at least one external, connectable device and/or at least one internal, removable device. The storage 19 has a capacity of 10's or 100's of gigabytes (GB), although it can have smaller or greater capacity. The storage 19 can store, among other things, content 21 including content 2 (FIG. 1), bookmarks 22 and extracted content 23. [0081] The record and playback device 1 also includes a user input/output interface 24, such as control panel having a display (not shown) and a set of buttons (not shown), for allowing a user to control the record and playback device 1 directly, an infrared receiver 25 for receiving signals from the remote control device 6 (FIG. 1) for allowing the user to control the record and playback device 1 remotely, a smart card reader 26 for receiving a smart card (not shown) holding data needed for decrypting signals. [0082] The record and playback device 1 further includes a first wireless network interface 27, in this case a PAN network interface with a corresponding antenna 28, a second wireless network interface 29, in this case a PLMN network interface with a corresponding antenna 30, and a wired network interface 31, in the form of a modem, for sending and receiving signals (not shown) via connector 32. [0083] The record and playback device 1 includes a transport stream parser 33, a video decoder 34, a subtitle decoder 35 and an audio decoder 36, a graphics processor 37 and an audio processor 38. [0084] The record and playback device 1 also includes several interfaces including a connector 39 for providing video and audio signals to the television set 5 (FIG. 1) and an audio connector 40 for providing audio-only signals to audio equipment (not shown). Additional ports may also be provided such as an auxiliary connector for providing signals to a videocassette recorder (not shown) or a data connectors for providing signals to a personal computer. [0085] In use, the front-end circuitry 13 receives a radio frequency signal 41 and produces a stream 42 of data packets. In this example, the data packets are in the form of MPEG-2 encapsulated transport stream (TS) packets. The stream 42 is passed to the demultiplexer 14, which separates the stream 42 into channels 43 1, 43 2, 43 n. The channels 43 1, 43 2, 43 n include at least one channel 43 1 carrying content 2 (FIG. 1) and at least one channel 43 2 carrying service information. The at least one channel 43 1 carrying content 2 can be selected by filter 15, which places data packets comprised in the channel 43 1 on the system bus 16 [0086] The data packets comprised in the channel 43 1 can be directed to storage 19 or to the transport stream parser 33. The transport stream parser 33 divides the data packets 43 1 according to the type of data and forwards divided streams 43 1A, 43 1B, 43 1C to respective decoders 34, 35, 36. The decoders 34, 35, 36 decode and decompress data packets and pass them on to the processors 37, 38 for further processing. Signals 44, 45 from the video and audio processors 37, 38 are fed to the video and audio connectors 39, 40 for transmission to the television set 5 (FIG. 1) and, optionally, additional speakers (not shown). [0087] The CPU 17 controls operation of the record and playback device 1 under instruction of at least one computer program 20. For example, when the record and playback device 1 is switched on, the CPU 17 loads and runs an operating system. The operating system includes device drivers to control hardware devices such as storage 19. Instructions as to how the record and playback device 1 should operate are received from an application run by the CPU 17, loaded from memory 18 or storage 19. In this example, applications are not platform specific. Therefore, additional software, often referred to as “middleware”, is used to help applications and the operating system communicate. [0088] Referring to FIG. 3, a functional layer structure 46 of the record and playback device 1 is shown. The record and playback device 1 uses hardware 47, such as storage 19, an operating system 48, middleware 49 and applications 50. The operating system 48 and the middleware 49 may be combined. In this example, middleware 49 includes a content storing and playing back engine 51 which includes an editing engine 52. The editing engine 52 can be used to create and manage files on storage 19. [0089] Digital broadcasting is preferably performed in accordance with ETSI Standard EN 300 744 “Digital Video Broadcasting (DVB): Framing structure, channel coding and modulation for digital terrestrial television” V.1.1.2 (1997) and related specifications. MPEG-2 encapsulation is described in more detail in MPEG-2 Systems ISO/IEC 13818-1. [0000] Mobile Terminal 8 [0090] Referring to FIG. 4, the mobile terminal 8 is shown in more detail. [0091] The mobile terminal 8 includes an antenna 53 and a first wireless network interface 54. The antenna 53 and first wireless network interface 54 are used to transmit and receive signals to and from the first wireless network 9, in this case PAN 9 (FIG. 1). The mobile terminal 8 also includes an antenna 55 and a second wireless network interface 56. The antenna 55 and second wireless network interface 56 are used to transmit and receive signals to and from the second wireless network 10, in this case PLMN 10 (FIG. 1). The wireless network interfaces 54, 56 each include respective r.f. signal processing circuits (not shown) for amplifying and demodulating received signals and respective processors (not shown) for channel decoding and demultiplexing. An additional antenna (not shown) and receiver (not shown) may also be provided for receiving signals from the broadcast network 4 (FIG. 1). [0092] The mobile terminal 8 also includes a controller 57, a user interface 58, memory 59, a smart card reader 60, smart card 61 received in the smart card reader 60, a coder/decoder (codec) 62, a speaker 63 with corresponding amplifier 64 and a microphone 65 with a corresponding pre-amplifier 66. [0093] The user interface 58 comprises a display 67 and a keypad 68. The display 67 is adapted for displaying images and video by, for instance, being larger and/or having greater resolution than a display of conventional mobile telephone and being capable of colour images. The mobile terminal 8 also includes a battery 69. [0094] The mobile terminal 8 also includes storage 70. The storage 70 is in the form of a hard disk drive. However, other types of storage can be used, such as an optical disk drive or solid-state memory or removable smart/memory cards. The storage 70 may comprise plural devices and may include at least one external, connectable device and/or at least one internal, removable device. The storage 70 has a capacity of a few gigabytes, although it can have greater capacity. The storage 70 can store, among other things, content 71, bookmarks 72 and extracted content 73. As will be explained in more detail later, bookmarks 72 and extracted content 73 can include or comprise bookmarks 22 and extracted content 23 transferred from the record and playback device 1 (FIG. 1). [0095] The controller 57 manages operation of the mobile terminal 8 under the direction of computer software 74 stored in memory 59. For example, the controller 57 provides an output for the display 67 and receives inputs from the keypad 68. [0096] Referring to FIG. 5, a functional layer structure 75 of the mobile terminal 8 is shown. The mobile terminal 8 uses hardware 76, an operating system 77, middleware 78 and applications 79. The operating system 77 and the middleware 78 may be combined. In this example, middleware 78 includes a content storing and playing back engine 80 which includes an editing engine 81. As will be explained in more detail later, the editing engine 81 can be used to transfer, create and manage files. [0000] Remote Control Device 6 [0097] Referring to FIG. 5, the remote control device 6 is shown in more detail. The device 6 includes a key pad 82, a controller 83, an infrared interface 84 and a battery 85. It will be appreciated that conventional remote control devices may be used. [0000] Transport Stream [0098] Referring to FIG. 7, the transport stream 42 carried by signal 41 (FIG. 2) is shown in more detail. [0099] The transport stream 42 comprises data packets 86 including data packets 87 1, 87 2 carrying video data and data packets 88 1 carrying service information. In this example, the data packets 86 are in the form of MPEG-2 encapsulated transport stream (TS) packets. [0100] Referring also to FIG. 8, the transport stream 42 is divided into a number of logical channels. The logical channel to which a data packet 86 belongs is defined in a packet header 89 using a packet identifier (PID) 90. The packet identifier can be used to identify contents of a data packet payload 91. [0101] For example, the contents of data packets 87 1, 87 2 may be identified as being video, by specifying a PID value between 0x0030 to 0x1FFE (as hexadecimal number). The contents of a data packet 88 1 may be identified as containing all or part of network information table (NIT) by specifying PID=0x0010. [0102] Referring also to FIG. 9, at least one of the data packets 86 is used for the purpose of timing. For example, a data packet 86 may include an adaptation field control (AFC) field 92 for indicating whether the packet header 89 is followed by an adaptation field 93 and/or payload 91. If the header 89 is followed by an adaptation field 93, the adaptation field may include a program clock reference (PCR) 94. [0103] The PCR 94 and the number of following packets can be used as a basis to refer to a location of a bookmark. [0104] As will be explained in more detail later, if content can be universally identified using a universal identification code, such as PCR 94, then a bookmark file which includes start and stop locations of the bookmarks in terms the universal identification code can become a universally usable file. Thus, the bookmark file can be transferred and used elsewhere to the same effect, namely to identify points, events or moments in the content. [0000] Playback [0105] Referring to FIG. 10, content 21 including content file 95 which is referred to as a playback file 95, is stored in storage 19. The playback file 95 comprises first and second parts 96, 97, a beginning 98, an intermediate point 99 and an end 100. [0106] Live content 101 comprising stream 43 1 (FIG. 2) is added to the second part 97 of the playback file 95 at the end 100 of the file 95. Because of this, the end 100 of the file 95 may be known as the “live position”. [0107] Content 102 is taken from the intermediate point 99 of the file 95 for playback. Because of this, the intermediate point 99 of the file 95 may be known as the “view position”. [0108] The first part 96 of the playback file 95 comprises content preceding the view position 99. The user may or may not have been watched the first part 96 of the playback file 95. The first part 96 of the file 95 may be known as the “instant replay buffer”. [0109] The second part 97 of the playback file 95 comprises content following the view position 99. The user may or may not have been watched the second part 97 of the playback file 95. The second part 97 of the file 95 may be known as the “live-view delta buffer”. [0110] As live content 101 is fed into the end 100 of the playback file 95, the play back file 95 grows. If playback is paused, then the live-view delta buffer 97 grows. If playback occurs, then the view position 99 shifts. Content which was once part of the live-view delta buffer 97 becomes part of the instant replay buffer 96. Thus, the live-view delta buffer 97 remains constant in size, while the instant replay buffer 96 grows. In either case, the size of the play-back file 95, and in particular the instant replay buffer 96, may be kept in check by deleting content 103 from the beginning 98 of the playback file 95. [0111] This type of playback is described in more detail in EP-A-1351500. [0112] A playback file 95 may be created and stored each time a channel is selected. A playback file 95 may be created when the record and playback device 1 is switched on, at the user's request or in response to some other control or trigger. A playback file 95 may include content from more than one channel. Playback file 95 may be deleted when the record and playback device 1 is switched off. The playback file 95 may be cropped, limiting it to a fixed size, so as to prevent the playback file becoming too large. However, the user may override the cropping function. [0113] In this example, the playback file 95 comprises televisual content including video and audio. However, the play back file 95 may comprise two or more files, for example one file for video, another file for audio and optionally further files for data, such as subtitles. The play back file 95 may be encrypted. Thus, content may need to be decrypted before rendering. [0114] Referring to FIG. 11, the remote control device 6 (FIG. 2) has a keypad 82 including keys 82 1, 82 2, 82 3 for controlling playback and keys 82 4, 82 5, 82 6 for controlling editing. A first key 82 1 is for “rewinding” to earlier recorded content. A second key 82 2 is for resuming live playback. A third key 82 3 is for “fast forwarding”. [0115] Referring also to FIG. 12, use of the playback control keys 82 1, 82 2, 82 3 is illustrated. [0116] The user presses the first key 82 1 at time t1. The controller 83 (FIG. 6) sends a command to the record and playback device 1 which causes the view position 99 to shift from a current position 99 1, which in this case happens to be the live position, to an earlier position 99 2. The shift may be a discontinuous jump to earlier content or a continuous, fast rewind to the earlier content through intervening content. If the user continuously presses the first key 82 1, then further shifting of the view position 99 may occur. [0117] Once the view position 99 has shifted, playback may continue. Thus, between time t1 and t2, the view position 99 can progress from the earlier position 99 2 to a new position 99 3. In the meantime, the playback file 95′ has grown. [0118] The user presses the second key 82 2 at time t2. The controller 83 (FIG. 6) sends a command to the record and playback device 1 which causes the view position 99 to shift from the new position 99 3 to the live position 100 at position 99 4. [0119] Referring to FIG. 13, the mobile device 8 (FIG. 2) has a keypad 68 including keys 68 1, 68 2, 68 3 for controlling playback and editing. The mobile device 8 (FIG. 2) may be provided with playback and editing functionality, for example by selecting an option from a menu (not shown). During playback and editing, if a key is 68 1, 68 2, 68 3 is pressed, then the controller 57 (FIG. 4) sends a command to the record and playback device 1 via the first wireless network 9, such as a PAN based on the Bluetooth™ specification. [0120] The first key 68 1 may be a four-direction joystick. Tilting the key 68 1 to the left and right can be used for rewinding and fast-forwarding content respectively. Pressing down on the key 68 1 can be used for returning the current view position 99 to the live position 100. Soft keys 68 2, 68 3 can be used for editing content, such as introducing bookmarks according to the soft key functions 104 1, 104 2 shown in display 67. [0000] Set-Up [0121] The record and playback device 1 can be used simply to playback content. However, as will be explained in more detail later, the record and playback device can also be used to bookmark content, to save specific content, to extract bookmarked content and to transfer bookmarks and/or specific and/or bookmarked content to another device, such as mobile terminal 8. [0122] The record and playback device 1 may be used by more than one user, such as members of a family or flatmates in shared accommodation. Therefore, the record and playback device 1 can also be configured to create personal bookmarks and to save and transfer personally selected content. [0123] Referring to FIGS. 2, 4, 14 and 15, a method of setting up a record and playback device 1 using a mobile terminal 8 for allowing creation of personal bookmarks and storage and transfer of personally-selected content will now be described. FIG. 14 illustrates operation of the record and playback device 1 and FIG. 15 illustrates operation of a co-operating controller, such as mobile terminal 8. [0124] The record and playback device 1 and the mobile terminal 8 may be paired (steps A1 & B1). For example, the record and playback device 1 and the mobile terminal 8 can be paired in accordance with the Bluetooth™ specification. Pairing may instead occur without Bluetooth connection, for example by using and creating a personal username and/or user id. When pairing, information concerning the paired devices and/or their users, and/or user identification may be stored. Information concerning the paired devices and their users may be later used as a user information when creating bookmark and extraction folders and files. [0125] When the user wishes to set-up the record and playback device 1, the user enters an instruction via keypad 68 for the controller 57 to create a network connection between the mobile terminal 8 and the record and playback device 1 via the PAN 8. This may be achieved by selecting an option from a menu (not shown). The controller 57 establishes a connection (steps A2 & B2). Alternatively, the user may enter an instruction via the user interface 24 for the CPU 17 to create the network connection. [0126] The user enters an instruction via keypad 68 for the controller 57 to instruct CPU 17 to create a bookmark folder 105 (FIG. 16) and/or an extracted content folder 121 (FIG. 17). This may also be achieved by selecting an option from a menu (not shown). The controller 57 transmits a request to create a bookmark folder 105 and/or an extracted content folder 121 (FIG. 17) (step B3) which the CPU 17 receives (step A3). [0127] The CPU 17 and controller 57 carry out user identification (steps A4 & B4). If Bluetooth™ protocols are being used, user identification may be carried out using Bluetooth™ authentication methods, which may or may not require user involvement. User identification when not using Bluetooth authentication, i.e. using a remote control device without Bluetooth technology, may involve asking the user to enter a user name and/or personal identification number (PIN), which are transmitted to the record and playback device 1 and stored in storage 19. [0128] The CPU 17 creates a bookmark folder 105 (FIG. 16) and/or an extracted content folder 121 (FIG. 17) for the user and stores the folders 105, 121 in storage 19 (step A5). [0129] The user enters identification information via keypad 68 and the controller 57 sends the information to the record and playback device 1 (step B5). The CPU 17 receives the information and adds it to the bookmark folder 105 (FIG. 16) and/or an extracted content folder 121 (FIG. 17). [0000] Bookmark Folder [0130] Referring to FIG. 16, an example of a bookmark folder 105 is shown. [0131] The bookmark folder 105 may comprise identification information 106, i.e. metadata, which may comprise user authentication information 107, user information 108, folder name 109, a flag 110 for indicating whether the folder can be shared and/or a user profile 111. [0132] As will be explained in more detail later, a number of bookmark files 112 1, 112 2, 112 N may be added to the bookmark folder 105. [0133] Taking the example of the first bookmark file 112 1, a bookmark file may comprise metadata such as user identification information 113 1, a bookmark file name 114 1, program identification 115 1, a flag 116 1 for indicating whether the file can be shared, personal features 117 1 and a set of bookmarks 118 1. The user identification information may be manually created, or copied and/or edited from user identification information that is created when pairing devices. [0134] The set of bookmarks 118 1 may comprise at least one start marker 119 11, 119 12, 119 1n and at least one end marker 120 11, 120 12, 120 1m. Start and end markers 119 11, 119 12, 119 1n, 120 11, 120 12, 120 1m may be paired, in which case they can define a start and end of a section. However, a marker 119 11, 119 12, 119 1n, 120 11, 120 12, 120 1m may be unpaired, in which case it simply marks a point, moment in time, event or the like and is herein after referred to as an “instant point”. [0135] The bookmarks 118 1 are in the form of pointers, for example added to the end of the playback file 95 or stored as a separate file. However, the bookmarks 118 1 may be inserted in a playback file 95. The bookmarks 118 1 employ PCR fields and packet number to identify a given point. However, other time stamping arrangements may be used. [0136] Each user may have a different bookmarking records for different uses. For example, a user may have a different bookmark folder for each type of content, such as sport, films and documentaries, or sub-type of content, such as ice hockey and soccer. This can help provide an extendible, linkable and flexible system for booking. [0137] The record and playback device 1 may automatically collect information about the bookmarks and the bookmarked contents and add them to the bookmark file 112 1, (e.g. to the program identification information file 115). This information may concern the size, duration and/or number of clips. Alternatively, some or all of this information can be added manually by a user. General content metadata information may be fully or partly copied from EPG (electronic program guide), ESG (electronic service guide) or ISG (interactive service guide) information or from the content itself. [0138] Bookmark files can be stored in the same storage, such as the same hard disc or the same DVD, in which content is stored. As will be explained in more detail later, bookmark files can be transferred from a set-top box to a mobile telephone handset via a Bluetooth™ network, and stored in the handset. Bookmark files can be used in the handset or transferred to friends. Use of a universal identification code, such as PCR, helps to identify the same position in both locally-available content and original content. Thus, a rented movie can be bookmarked and the bookmarks shared between friends. [0139] Bookmark files can be stored on personal storage, such as a memory stick, which is provided with connectivity, such as Bluetooth™. [0140] Bookmark files can be downloaded or transferred to a mobile telephone handset using MMS or SMS via a PLMN. Not only can friends exchange or deliver bookmarks, but also a company or any external party may provide a service, such as advertising or reviewing movies or any other digital content, to users. Limiting the number of scenes helps to keep the size of the bookmark file small. Bookmark files can also be downloaded or transferred from a company or any external party to a STB (set-top box) or similar using MMS or SMS via a PLMN, or wireline network, such as the Internet. [0141] Bookmark folders and bookmark files may be presented in EPG (electronic program guide), ESG (electronic service guide), in ISG (interactive service guide) or together with any other form of program information. A specific bookmark file may presented together with related actual digital content, so that user may select the bookmark to watch the actual content or its highlights. [0000] Extracted Content Folder [0142] Referring to FIG. 17, an example of an extracted content folder 121 is shown. [0143] The extracted content folder 121 may comprise user identification information 122, i.e. metadata information, which may comprise user authentication information 123, user information 124, a folder name 125, a flag 126 for indicating whether the folder can be shared and/or a user profile 127. [0144] As will be explained in more detail later, a number of extracted content files 128 1, 128 2, 128 Q may be added to the extracted content folder 121. [0145] Taking the example of the first extracted content file 128 1, a extracted content file may comprise metadata information such as user identification information 129 1, a bookmark file name 130 1, program identification 131 1, a flag 132 1 for indicating whether the file can be shared, personal features 133 1 and a set of extracted content 134 11, 134 12, 134 1p. Each extracted content 134 11, 134 12, 134 1p may correspond to a respective pair of start and end markers 119 11, 119 12, 119 1n, 120 11, 120 12, 120 1m (FIG. 16). Extracted content file information may be fully or partly inherited from a corresponding bookmark file, and manually edited by a user. [0146] Referring again to FIGS. 2, 4, 14 and 15, the CPU 17 saves the bookmark folder 105 (FIG. 16) and/or the extracted content folder 121 (FIG. 17) in storage 19 (step A7). [0147] The user may wish to receive a copy of the bookmark folder 105 (FIG. 16) and/or the extracted content folder 121 (FIG. 17). If so, the user enters an instruction via keypad 68 to transmit a copy of the bookmark folder 105 (FIG. 16) and/or the extracted content folder 121 (FIG. 17). The controller 57 transmits a request to the record and playback device 1 to transmit the bookmark folder 105 and/or the extracted content folder 121 (FIG. 17) (step B6). [0148] If the CPU 17 receives a request to transmit the bookmark folder 105 and/or the extracted content folder 121 (FIG. 17) to the mobile terminal 8 (step A8), then the CPU 17 transmits the bookmark folder 105 and/or the extracted content folder 121 (FIG. 17), for example via the first wireless network 9 (steps A9). [0149] The controller 57 receives the bookmark folder 105 and/or the extracted content folder 121 (FIG. 17) (step B7) and saves the folder or folders 105, 121 in storage 70. [0150] Additionally or alternatively, the remote control unit 6 or the user interface 24 may be used to set up the record and playback device 1. The method is substantially similar to that just described. The method using the remote control unit 6 may differ in that the instructions are sent via the infrared interface 7 (FIG. 1). For example, the remote control device 6 may be easier to use for certain steps than the mobile terminal 8. [0151] Regardless of whether the mobile terminal 8, the remote control unit 6 or the user interface 24 is used, the user may instruct the record and playback device 1 to transmit the bookmark folder 105 and/or the extracted content folder 121 (FIG. 17) to the mobile terminal 8 or to another device 1, via the PAN 9 or PLMN 10, for example as a data message, or in the case of another record and playback device 1′ connected to the wired network 11, via the wired network 11. [0152] Regardless of whether the record and playback device 1 is controlled by the remote control device 6, mobile terminal 8 or keypad of the user interface 24, the record and playback device 1 may display instructions or prompts for the user on the television set 5 or via the display (not shown) of the user interface 24. [0153] Extraction folders and extraction files may be presented in EPG (electronic program guide), ESG (electronic service guide), in ISG (interactive service guide) or together with any other form of program information. A specific bookmark file may presented together with related actual digital content and/or related bookmark file, so that user may select the bookmark to watch the actual content or its highlights. [0000] Bookmarking [0154] The user may bookmark content and then save bookmark and personally selected content to their own or shared folders 105, 121. [0155] The user may bookmark content while content is being received and/or being recorded in the playback file or after content has been recorded. It can help the user to locate given events, moments or scenes. It can also help the user to restart viewing quickly and easily from a given point at a later time. [0156] A set of bookmarks may be assigned a category, such as a film genre or program type. This can help the user to manage his or her bookmarks. Furthermore, a set of bookmarks may be assigned the name of a user. This allows different users to have their own set of bookmarks for the same material. Thus, only a selected set of bookmarks or, if the user interface allows it, several sets of bookmarks can be activated when browsing through material, i.e. content. [0157] If a user defines a bookmark having a start and stop time, the user can piece together highlights of film or program for viewing a later stage. If several such bookmarks are defined then the user can make an “executive summary” of the recording and/or make a shorter version of the film, which may be referred to as a “user's cut” or a “user's choice”. [0158] Referring to FIGS. 2, 4, 18 and 19, a method of bookmarking and extracting content will now be described. FIG. 18 illustrates operation of the record and playback device 1 and FIG. 19 illustrates operation of a co-operating controller, such as mobile terminal 8. [0159] If a connection has not already been established, the user may enter an instruction via keypad 68 for the controller 57 to create a network connection between the mobile terminal 8 and the record and playback device 1 via the PAN 8. This may be achieved by selecting an option from a menu (not shown). The controller 57 establishes a connection. Alternatively, the user may enter an instruction via the user interface 24 for the CPU 17 to create the network connection. [0160] The user selects a channel. This may be achieved by the user entering a channel number via keypad 68 or by selecting a channel from a menu (not shown) displayed on the television set 5. Thus, the controller 57 sends a request to stream content for a given channel which is received by record and playback device 1 (steps C1 & D1). [0161] The user may view and playback content as described earlier. [0162] The user selects bookmarking via keypad 68 and the controller 57 sends a request to the record and playback device 1 to activate bookmarking (steps C2 and D2). Alternatively, bookmarking may be automatically activated when content begins to be received or always enabled. [0163] The CPU 17 and controller 57 carry out user identification (steps C3 & D3). If Bluetooth™ protocols are being used, user identification may be carried out using Bluetooth™ authentication methods, which may or may not require user involvement. If not using Bluetooth™, user identification may involve asking the user to enter a user name and/or PIN which are transmitted to the record and playback device 1 and compared with a user name stored in storage 19. If there is a match, then the user is identified. [0164] The CPU 17 creates a bookmark file 112 1 (FIG. 16) in the user's bookmark folder 105 (FIG. 16) stored in storage 19 (step C4). [0165] The user may be prompted to provide bookmark file information. Prompted or unprompted, the user may enter bookmark file information 115 1 (FIG. 16), such as a bookmark file name 114 1 (FIG. 16), program identification 115 1 (FIG. 16), a flag 116 1 (FIG. 16) for indicating whether the file can be shared and personal features 117 1 (FIG. 16) (such as comments, message and/or a description) via keypad 68 and/or by selecting names from a menu, which the controller 57 transmits to the record and playback device 1 (steps C5 & D4). [0166] The user may be prompted as to whether to extract content between a start and end marker or a still picture at an instant point and place the extracted content in a file. Prompted or unprompted, the user may enter an instruction via keypad 68 to extract content. The controller 57 transmits a request to extract content (step C6 & D5). [0167] If the CPU 17 receives an instruction to extract content (step C7), it creates an extracted content file 128 1 (FIG. 17) in the user's extracted content folder 121 (FIG. 17) stored in storage 19 (step C8). However, the CPU 17 may automatically create an extracted content file 128 1 (FIG. 17). [0168] The user may be prompted to provide extracted content file information. Prompted or unprompted, the user may enter extracted content file information such as a bookmark file name 130 1 (FIG. 17), program identification 131 1 (FIG. 16), a flag 132 1 (FIG. 16) for indicating whether the file can be shared and personal features 133 1 (FIG. 16) (such as comments, message and/or a description) via keypad 68 and/or by selecting names from a menu, which the controller 57 transmits to the record and playback device 1 (steps C9 & D6). However, the CPU 17 may automatically copy the extracted content file information from the bookmark file information. [0169] Either before, during or after the steps of creating a bookmark file and an extracted content file, the content 3 is selected and provided as live content 101 (FIG. 10) for storing and playing back (step C10). [0170] The live content 101 (FIG. 10) is synchronised with the bookmark file 112 1 (FIG. 16) (step C11). A PCR (or some other PID) may be stored to used to locate the exact locations of bookmarks in a content file. Reference is made to FIGS. 8 to 10 and the corresponding description above. Program identification information in the bookmark file includes information that identifies the corresponding content file. [0171] The user may begin bookmarking content (step C12 & D7). [0172] Referring also to FIG. 20, the bookmarking process is shown in more detail: [0173] Briefly stated, the bookmarking process includes two sub-processes. A first sub-process is for when the record and playback device 1 is in a first state, for example when no bookmarks have been placed or when the last bookmark to have been placed is an end bookmark (steps C12.1 to C12.5). A second sub-process is for when the record and playback device 1 is in a second state, for example when the last bookmark to have been placed is a start bookmark (steps C12.6 to C12.16). [0174] In the first state, the user may forward or rewind content before bookmarking. Therefore, a check is made whether the user has pressed forward or rewind (step C12.1). If so, content is forwarded or rewound accordingly (step C12.2). If not, a check is made whether the user wishes to place a start point bookmark (step C12.3) [0175] For example, if the key 68 1 is tilted to the right or left, then the controller 57 sends a forward or rewind command to the record and playback device 1. If the CPU 17 is notified by the controller 57 that the key 68 1 has been tilted to the right or left, it moves the current position 99 (FIG. 10) forwards or backwards accordingly. Additionally or alternatively, the current position 99 may progress as the user watches the content. [0176] It will be appreciated that the user need not forward or rewind content. It will also be appreciated that the user may not be allowed to forward or rewind content, for example if the view position is at the end 98 or start 100 of the playback file 95. [0177] Whether or not the user forwards or rewinds content, a check is made whether the user wishes to place a start point bookmark (step C12.3 & D7). If so, a start point bookmark is placed (step C12.4). If not, a check is made whether the user wishes to quit bookmarking (step C12.5). [0178] For example, if the start key 68 2 is pressed, then the controller 57 sends start point command to the record and playback device 1. If the CPU 17 is notified by the controller 57 that the user has pressed the start button 68 2, it stores a start point 119 1 in bookmarks 118 1. Otherwise, it continues to monitor whether the key 68 1 has been tilted or if the start key 68 2 has been pressed. [0179] If the user has not pressed the start button, a check is made whether the user wishes to quit bookmarking (step C12.5). [0180] For example, if a cancel key 68 4 (FIG. 13) is pressed, then the controller 57 sends a quit bookmarking instruction to the record and playback device 1. If the CPU 17 is notified by the controller 57 that the cancel key 68 4 (FIG. 13) has been pressed, then it quits bookmarking. An instruction to quit bookmarking may be implied, for example if the user switches channel. [0181] If the user has not quit bookmarking, then the record and playback device 1 remains in the first state and continues to monitor whether the forward/rewind buttons have been pressed, whether the start point bookmark has been placed or whether the user wishes to quit bookmarking (step C12.1 to C12.5). [0182] It will be appreciated that CPU 17 may monitor and act upon other user instructions, such as volume control. [0183] If a start point bookmark has been placed, then the record and playback device 1 switches to a second state. [0184] In the second state, the user may forward or rewind content before further bookmarking. Therefore, a check is made whether the user has pressed forward or rewind (step C12.6). If so, content is forwarded or rewound accordingly (step C12.7). If not, a check is made whether the user wishes to place a start point bookmark (step C12.8). [0185] For example, if the key 68 1 is tilted to the right or left, then the controller 57 sends a forward or rewind command to the record and playback device 1. If the CPU 17 is notified by the controller 57 that the key 68 1 has been tilted to the right or left, it moves the current position 99 (FIG. 10) forwards or backwards accordingly. Additionally or alternatively, the current position 99 may progress as the user watches the content. [0186] It will be appreciated that the user need not forward or rewind content. It will also be appreciated that the user may not be allowed to forward or rewind content, for example if the view position is at the end 98 or start 100 of the playback file 95. [0187] Whether or not the user forwards or rewinds content, a check is made whether the user wishes to place a start point bookmark (step C12.8 & D7). If so, a check is made whether the previous bookmark was a start point bookmark is placed (step C12.9). If not, a check is made whether the user wishes to place an end point bookmark (step C12.10). [0188] For example, if the start key 68 2 is pressed, then the controller 57 sends start point command to the record and playback device 1. If the CPU 17 is notified by the controller 57 that the user has pressed the start button 68 2, it checks whether the previous bookmark was a start point 119 1 or an end point 120 1. [0189] If the previous bookmark was not a start point 119 1, in other words it was an end point 120 1, then a start point bookmark is placed 119 2 (step C12.11). [0190] For example, the CPU 17 stores another start point 119 2 in bookmarks 118 1 and continues to monitor for notifications from the controller 57. [0191] If the previous bookmark was a start point 119 2 and there is no end point paired with it, then the start point 119 2 is an instant point (step C12.12). A start point bookmark 119 3 is placed (step C12.13) and a check is made whether the user wishes to fast-forward or rewind continues (step C12.6). [0192] For example, the CPU 17 checks whether an end point follows start point 119 2. If it does not find an end point, then it stores another start point 119 3 in bookmarks 118 1 and continues to monitor for notification by the controller 57. Optionally, the CPU 17 may place a flag or identifier for indicating that start point 119 2 is unpaired. [0193] An example of two successive start point bookmarks 119 1, 119 2 in a playback file 95 is shown in FIG. 21. The first start point bookmark 119 1 is placed at time t3 and a second start point bookmarks 119 2 is placed at time t4. Placing the second start point bookmarks 119 2 after the first start point bookmark 119 1 without the first start point bookmark 119 1 being paired with an end point bookmark results in the first start point bookmark 119 1 becoming an instant point. [0194] If the user does wish to place a start point (step C12.8), then a check is made whether the user wishes to place an end point bookmark (step C12.10). If so, an end point bookmark is placed (step C12.14), thus defining a segment or section (C12.15). The record and playback device 1 returns to the first state. If not, a check is made whether the user wishes to quit bookmarking (step C12.16). [0195] For example, if the end key 68 3 is pressed, then the controller 57 sends end point command to the record and playback device 1. If the CPU 17 is notified by the controller 57 that the user has pressed the end button 68 3, it places an end point bookmark 120 1 in bookmarks 118 1 and pairs the end point 120 1 with start point 119 1. [0196] An example of a pair of start and end point bookmarks 119 1, 120 1 in a playback file 95 is shown in FIG. 22. The start point bookmark 119 1 is placed at time t5 and end point bookmarks 120 1 is placed at time t6. Placing the end point bookmark 120 1 after the start point bookmark 119 1 results in the start and end point bookmarks 119 1, 120 1 being paired and a section 135 being defined. Content within section 135 can be extracted. [0197] If the user does wish to place a start point or an end point, then a check is made whether he or she wishes to quit bookmarking (steps C12.16). [0198] For example, if a cancel key 68 4 (FIG. 13) is pressed, then the controller 57 sends a quit bookmarking instruction to the record and playback device 1. If the CPU 17 is notified by the controller 57 that the cancel key 68 4 (FIG. 13) has been pressed, then it quits bookmarking. An instruction to quit bookmarking may be implied, for example if the user switches channel. [0199] If the user has not quit bookmarking, then the record and playback device 1 remains in the second state and continues to monitor whether the forward/rewind buttons have been pressed, whether another start point bookmark or an end point bookmark has been placed or whether the user wishes to quit bookmarking (step C12.6 to C12.16). [0200] Referring to FIG. 23, if the user quits bookmarking at step C12.16, then any unpaired start point bookmark 119 2 becomes an instant point. [0201] Referring again to FIGS. 18 and 19, when the user has finished bookmarking (steps D8 & D9 and step C12.5 or C12.16), if the CPU 17 has not already done so, it saves the bookmarks in the bookmark file 118 1 (step C13). [0202] If the CPU 17 has received an instruction to extract content, then it extracts content corresponding to sections 135 (FIG. 22) and/or instant points 119 1, 119 2 (step C14 & C15) and saves extracted content 134 1 (FIG. 17) (step C16). [0203] The user may instruct the record and playback device 1 to transmit at least bookmark and/or extracted content files 112 1, 112 2, 112 N, 128 1, 128 2, 128 N to the mobile terminal 8 (FIG. 1) or other device (step D10). However, the user may have provided instructions earlier, for example when providing bookmark or extracted content file information. [0204] If the CPU 17 has received an instruction to transmit the bookmark files 112 1 and/or any other bookmark files 112 2, 112 N to the mobile terminal 8 (FIG. 1) or other device, then the CPU 17 transmit the bookmark files 112 1, 112 2, 112 Q accordingly (steps C18 & C19). However, the CPU 17 may automatically attempt to transmit the bookmark files 112 1 immediately on quitting bookmarking. [0205] If the CPU 17 has received an instruction to transmit the extracted content file 128 1 and/or any other extracted content files 128 2, 128 Q to the mobile terminal 8 (FIG. 1) or other device, then the CPU 17 transmit the extracted content files 128 1, 128 2, 128 Q accordingly (steps C20 & C21). However, the CPU 17 may automatically attempt to transmit the extracted content files 128 1 immediately on quitting bookmarking. [0206] Upon receipt of files 112 1, 112 2, 112 N, 128 1, 128 2, 128 N the mobile terminal 8 may save the files 112 1, 112 2, 112 N, 128 1, 128 2, 128 N in storage 70 (FIG. 4). [0207] The user may employ the remote control device 6 instead of mobile terminal 8 for transmitting some or all of the instructions shown in FIG. 19. For example, the user may use the remote control device 6 to select a channel and to lay down start and end points, while using the mobile terminal 8 to set up bookmark and extracted content files. [0208] More than one user may bookmark while watching the same content. Therefore, the record and playback device 1 may perform some or all of the steps shown in FIGS. 18 and 20 for each user. Thus, plural mobile terminals and/or plural remote control devices may be used. [0000] Bookmarking an Ice Hockey Game [0209] An example of a situation when a user might want to use bookmarking is watching a game, such as a game of ice hockey. [0210] The ice hockey game is received and played back using storage 19 (FIG. 1). While watching the game, the user wants to store the highlights of the game in his or her personal bookmark folder 105 (FIG. 16) for future viewing. For example, the user may want to keep an archive of highlights from a team's games in a season. Each game may be stored as a different bookmark file (112 1, 112 2, 112 N). [0211] If the user notices an incident, he or she can keep a record of the incident using bookmarks. For example, a player is fouled and the opposing team is given a two-minute penalty. The user can record the incident in a number of ways: [0212] Firstly, the user can rewind content, replay the foul and place bookmarks while watching. The user can insert a start point bookmark just before the foul and an end point bookmark when the two-minute penalty expires. The bookmarks specify a segment of content. As explained earlier, the user may control bookmarking using the remote control device or their mobile phone. [0213] Secondly, the user can wait for a replay, i.e. a replay defined by the production team or content provider. The user can insert a start point bookmark as the replay starts and an end point bookmark as the replay ends without needing to rewind and fast-forward. One drawback of this approach is that not all incidents are replayed. On the other hand, replays can include different views of the same incident. [0214] Of course, the user can combine both approaches or can insert bookmarks “on-the-fly”. [0215] During the course of a game, the user can insert several bookmarks which define a plurality of plural segments, each one relating to different incidents. After the game, the can user stores the bookmarks in separate files in his or her personal bookmark folder in storage 19. [0216] If user does not want to store the whole game, he or she can extract the highlights of the game by running the specific bookmark file with the content file and saving the extracted content in an extracted content file in an extracted content folder in storage 19. [0217] Extracting selected content from original content using bookmarks reduces the content to be stored, transmitted and viewed. This is beneficial when transmitting content wirelessly, since it saves storage capacity in storage devices by making it possible to delete the original content. It can also be time saving by offering summaries or highlight of the original content to be viewed. [0218] As will be described later, the user can edit the bookmark file to watch and/or extract different versions of highlights of the game. [0219] As will also be explained in more detail later, the user can transmit the bookmark file with a content file or the extracted content file to his mobile terminal. Next day, for example, he or she can show the highlights of the game to his colleagues at work by playing back the extracted file or bookmark file together with the content file. [0220] As will also be explained in more detail later, the user can transmit the extracted content file to a friend to allow the friend to watch the game's highlights. Alternatively, the user can transmit only the bookmark file. In turn, the friend can transmit the bookmark file to their own record and playback device 1′ (FIG. 30) and run the bookmark file with their own recorded content file. The friend can watch, extract content, edit and save the highlights as they please using their own record and playback device 1′. [0221] Extracting selected content from original content using bookmarks reduces the content to be stored, transmitted and viewed. This is beneficial when transmitting content wirelessly, since it saves storage capacity in storage devices by making it possible to delete the original content. This may also be time saving by offering summaries or highlight of the original content to be viewed. [0000] Editing [0222] The user may edit bookmark content and save bookmarks and personally-selected content to their own or shared folders 105, 121. [0223] Referring to FIGS. 2, 4, 24 and 25, a method of editing bookmarks will now be described. FIG. 24 illustrates operation of the record and playback device 1 and FIG. 25 illustrates operation of a co-operating controller, such as mobile terminal 8. [0224] If a connection has not already been established, the user may enter an instruction via keypad 68 for the controller 57 to create a network connection between the mobile terminal 8 and the record and playback device 1 via the PAN 8. This may be achieved by selecting an option from a menu (not shown). The controller 57 establishes a connection. Alternatively, the user may enter an instruction via the user interface 24 for the CPU 17 to create the network connection. [0225] The user selects editing via keypad 68 and the controller 57 sends a request to the record and playback device 1 to begin editing (steps E1 and F1). [0226] The CPU 17 and controller 57 carry out user identification (steps E2 & F2). If Bluetooth™ protocols are being used, user identification may be carried out using Bluetooth™ authentication methods, which may or may not require user involvement. If not using Bluetooth™ authentication, user identification may involve asking the user to enter a user name and/or PIN which are transmitted to the record and playback device 1 and compared with a user name stored in storage 19. If there is a match, then the user is identified. [0227] The user selects a bookmark file, for example the first bookmark file 112 1, via keypad 68 and the controller 57 sends a request to the record and playback device 1 to open the bookmark file 112 1 (steps E3 & F3). This may be achieved by selecting an option from a menu (not shown) displayed, for example on the mobile terminal's display 67 or the television set 5. [0228] The CPU 17 opens the selected bookmark file 112 1 (step E4). The CPU 17 may display the contents of the bookmark file 112 1, for example using the television set 5. The bookmark file name 114 1 may be displayed as text. Bookmarks 119 1, 120 1, 119 2, 119 3, 119 2, 120 m may be displayed as thumbnail pictures. Bookmarks 119 1, 120 1, 119 2, 119 3, 119 2, 120 1 may be shown as positions in the playback file 95 in a similar format to that shown in FIGS. 21 to 23. Bookmarks 119 1, 120 1, 119 2, 119 3, 119 2, 120 m may be listed, for example according to name or timing. [0229] The user may edit the bookmark file 112 1 by entering instructions and/or text via keypad 68. The controller 57 sends the instructions and/or text to the record and playback device 1 and the CPU 17 edits the bookmark file 112 1 accordingly (steps E4 & F4). [0230] For example, editing the bookmark file 112 1 may include adding or changing the bookmark file name 114 1. Editing the bookmark file 112 1 may include adding, shifting, deleting or changing the type of bookmarks 119 1, 120 1, 119 2, 119 3, 119 2, 120 1. Editing the bookmark file 112 1 may include adding, changing or deleting icons or pictures for bookmarks 119 1, 120 1, 119 2, 119 3, 119 2, 120 m. Editing the bookmark file 112 1 may include adding, changing or deleting personal features 117 1. Editing the bookmark file 112 1 may include copying, renaming or deleting the bookmark file 112 1. [0231] Once editing has been completed, the CPU 17 saves the selected bookmark file 112 1 to storage 16 (step E6). [0232] The user may request for the bookmark file 112 1 or a copy thereof to be transmitted to another device, such as mobile terminal 8. The user enters an instruction via keypad 68 and the controller 57 sends an instruction to the record and playback device 1 to transmit the bookmark file 112 1 (steps F5). [0233] If the CPU 17 receives an instruction to transmit the bookmark file 112 1, then it transmits the bookmark file 112 1 (steps E7 & E8). [0234] The controller 57 receives the bookmark file 112 1 and saves the file in storage 19 (steps F6 & F7). [0235] Thus, the user can edit bookmarks and organise a collection of bookmarks. [0236] He or she may assign parameters to the bookmark collection, such as name, owner and description. [0237] He or she may provide additional information or content. For example, they may add a sound recording of screaming and shouting occurring in a living room during ice-hockey match. He or she may add text notes, voice-overs or other content, for instance in a picture-in-picture window. This can be used for home-video applications or professional editing application. He or she may add links to other bookmarks in previously recorded content, such as goals in previous matches. [0238] He or she can copy the bookmark collection, rename the copy and make changes by adding, moving and removing bookmarks to/from the copy to make it more suitable for some other purposes. [0239] The user may allow another user to access the content or the bookmarks. Access may be granted on different levels, such Although the other user may not authorised to edit the user's bookmarks, he or she may be permitted to access previously recorded bookmarks, which could be made visible (while watching the contents) to the user somehow [0240] As mentioned earlier, the user can make an “executive summary” of the recorded material by adding bookmarks throughout the recorded material. [0241] The user can process bookmarks and extracted content to provide an improved executive summary. For example, he or she can introduce fading out and fading in of sound between bookmark sections and fading out. Additionally or alternatively, they can introduce fading out and fading in of a picture between bookmark sections using a background or special effects. He or she can search for convenient cut-off points close to the selected bookmark and mark them. [0242] Fade-in and fade-out effects can be achieved by editing the playback file and storing the executive summary as an additional file or as a replacement for the playback file. Fade-in and fade-out effects can also be achieved by making a bookmark file, which may be an additional file or an extension of an original bookmark file, containing the fading effects and replacing the original audio and/or video at run-time. [0000] Extracting Content [0243] As mentioned earlier, the user may wish to render content using another device, such as mobile terminal 8. To minimise unnecessary data transfer, the user may extract relevant content from the playback file and transmit only the extracted content. [0244] Referring to FIGS. 2, 4, 26 and 27, a method of extracting content will now be described. FIG. 26 illustrates operation of the record and playback device 1 and FIG. 27 illustrates operation of a co-operating controller, such as mobile terminal 8. [0245] If a connection has not already been established, the user may enter an instruction via keypad 68 for the controller 57 to create a network connection between the mobile terminal 8 and the record and playback device 1 via the PAN 8. This may be achieved by selecting an option from a menu (not shown). The controller 57 establishes a connection. Alternatively, the user may enter an instruction via the user interface 24 for the CPU 17 to create the network connection. [0246] The user selects an option to open a bookmark file via keypad 68 and the controller 57 sends a request to the record and playback device 1 to open a bookmark file (steps G1 and H1). [0247] The CPU 17 and controller 57 carry out user identification (steps G2 & H2). If Bluetooth™ protocols are being used, user identification may be carried out using Bluetooth™ authentication methods, which may or may not require user involvement. User identification may involve asking the user to enter a user name and/or PIN which are transmitted to the record and playback device 1 and compared with a user name stored in storage 19. If there is a match, then the user is identified. [0248] The user selects a bookmark file, for example the first bookmark file 112 1, via keypad 68 and the controller 57 sends a request to the record and playback device 1 to open the bookmark file 112 1 (steps G3 & H3). This may be achieved by selecting an option from a menu (not shown) displayed, for example on the mobile terminal's display 67 or the television set 5. [0249] The CPU 17 opens the selected bookmark file 112 1 (step G4). [0250] The user selects an option to extract content via keypad 68 and the controller 57 sends a request to the record and playback device 1 (steps G5 and H4). [0251] The CPU 17 may display a number of extraction options to the user, for example via the television set 5. The options may include extraction of content from all segments sequentially, extraction of content from selected segments, extraction of content from one selected bookmark, extraction of content from all instant points (i.e. extraction of stills pictures) and/or extraction of content from selected instant points. [0252] The user selects an extraction via keypad 68 and the controller 57 sends a request to the record and playback device 1 (steps G6 and H5). [0253] The user enters identification information, such as name 130 1, via keypad 68 and the controller 57 sends the information to the record and playback device 1 (steps G6). The CPU 17 receives the information, creates an extracted content file, for example extracted content file 128 1, and adds the information to the extracted content file 128 1 (FIG. 17) (steps G7 & G8). [0254] The playback file 95 (FIG. 10) is synchronised with the bookmark file 112 1 (FIG. 16) (step G9) and content is extracted to the extracted content file 128 1 (FIG. 17) (step G10). [0255] The extracted content may be played back while extraction is taking place. The user may instruct the store and playback device 1 to playback the extracted content. [0256] The CPU 17 extracts content from the playback file 95 (step G10), optionally forwards the content for rendering by the television set 5 (steps G11 & G12) and saves the content to the extracted content file 128 1 in storage 19 (step G13). [0257] The user may request for the extracted content file 128 1 or a copy thereof to be transmitted to another device, such as mobile terminal 8. The user enters an instruction via keypad 68 and the controller 57 sends an instruction to the record and playback device 1 to transmit the extracted content file 128 1 (steps H7). [0258] If the CPU 17 receives an instruction to transmit the extracted content file 128 1, then it transmits the extracted content file 128 1 (steps G14 & G15). [0259] The controller 57 receives the extracted content file 128 1 and saves the file in storage 19 (steps H8 & H9). [0000] Transmitting Files to Another Device [0260] As mentioned earlier, the user may wish transmit a bookmark file, an extracted content file and a content file to another device, such as mobile terminal 8. [0261] Referring to FIGS. 2, 4, 28 and 29, a method of transmitting files content will now be described. FIG. 28 illustrates operation of the record and playback device 1 and FIG. 29 illustrates operation of a co-operating controller, such as mobile terminal 8. [0262] If a connection has not already been established, the user may enter an instruction via keypad 68 for the controller 57 to create a network connection between the mobile terminal 8 and the record and playback device 1 via the PAN 8. This may be achieved by selecting an option from a menu (not shown). The controller 57 establishes a connection. Alternatively, the user may enter an instruction via the user interface 24 for the CPU 17 to create the network connection. [0263] The user selects an option via keypad 68 and the controller 57 sends a request to the record and playback device 1 to transmit a bookmark file, an extract content file or a playback file (steps I1-I3 & J1-J3). [0264] The CPU 17 and controller 57 carry out user identification (steps I4 & J4). If Bluetooth™ protocols are being used, user identification may be carried out using Bluetooth™ authentication methods, which may or may not require user involvement. User identification may involve asking the user to enter a user name and/or PIN which are transmitted to the record and playback device 1 and compared with a user name stored in storage 19. If there is a match, then the user is identified. [0265] The user selects a bookmark file, for example the first bookmark file 112 1, an extracted content file, such as extracted content file 128 1 and/or playback file, such as playback file 95, via keypad 68 and the controller 57 sends a request to the record and playback device 1 to transmit the file or files 112 1, 128 1, 95 (steps I5-I7 & J5-J7). This may be achieved by selecting an option from a menu (not shown) displayed, for example on the mobile terminal's display 67 or the television set 5. [0266] The CPU 17 transmits the file or files 112 1, 128 1, 95 (steps 18). [0267] The controller 57 receives the file or files 112 1, 128 1, 95 and the file or files 112 1, 128 1, 95 in storage 19 (steps J8 & J9). [0000] Playing Back an Extracted Content File in Another Device [0268] Referring to FIG. 30, the record and playback device 1 can transmit content and files to another record and playback device 1′ via one or more mobile terminals 8, 8′. The other record and playback device 1′ is substantially similar to the record and playback device 1′ shown in FIG. 2. For example, the record and playback device 1′ includes a CPU 17′ and storage 19′. [0269] Alternatively the record and playback device 1 may transmit content and files directly to the another record and playback device 1′ via PAN or PLMN. [0270] As described earlier, the record and playback device 1 can transfer a file or files 112 1, 128 1, 95 to the mobile terminal 8. In turn, these can be transferred to another mobile terminal 8′ is the same way. [0271] Referring also to FIG. 31, the mobile terminal 8, 8′ may store a content folder 136, a bookmark folder 137 and an extracted content folder 138 which include a copy of the playback file 95, a copy of the bookmark file 112 1 and a copy of extracted content file 128 1 respectively. The user may edit the files 112 1, 128 1, 95 in a similar way to that described earlier. The user may transfer other files (not shown) from the record and playback device 1 or other devices and store them in folders 136, 137, 138. Thus, it will be appreciated that the bookmark and extracted content folders 137, 138 stored in mobile terminal 8 may differ from the bookmark and extracted content folder 105, 121 stored in the record and playback device 1. [0272] Referring to FIGS. 2, 4, 31, 32 and 33, a method of transmitting files and/or content will now be described. FIG. 32 illustrates operation of the mobile terminal 8 and FIG. 33 illustrates operation of other record and playback device 1′. [0273] The user selects the bookmark folder 137 stored in the mobile terminal 8. The controller 57 opens the selected bookmark folder (step K1) and presents the user with a set of options. The user selects an option to transmit files to another record and playback device 1′. The controller 57 receives the instruction (step K2) and presents the user with a list of files. The user can select which files he or she wishes to transmit to record and playback device 1′ (step K3). In this example, the user selects to transmit the bookmark file 1121. [0274] The controller 57 automatically establishes a connection between the mobile terminal 8 and the record and playback device 1′ via the PAN 8′ (steps K4 & L1). However, the controller 57 may wait until instructed to do so by the user. [0275] The controller 57 transmits the selected file or files to the record and playback device 1′ (step K5). In example, only the bookmark file 112 1 is transmitted. [0276] The record and playback device 1′ stores the file or files in storage 19′ (step L3). [0277] The user may request playback of extracted content or still-to-be-extracted content. The request may request playback of extracted content using the mobile terminal 8 (step K6). Thus, the controller 57 transmits an instruction to playback extracted content to the record and playback device 1′. Alternatively, the user may request playback using remote control device 6′. [0278] The CPU 17′ checks whether it has received a request to play back extracted content (step L4). [0279] When the CPU 17′ is instructed to play back extracted content, it checks whether it received the appropriate extracted content file corresponding to the bookmark file (step L5). If so, it can proceed by playing back the extracted content file (step L6). If not, the CPU 17′ checks whether it has received the appropriate playback file (step L7). In this case, the appropriate playback file is playback file 95. [0280] If the appropriate playback file has not been received, the CPU 17′ checks whether it has a playback file with the appropriate content (step L8). If not, then the record and playback device 1′ cannot as yet extract and render the bookmarked content. [0281] If the record and playback device 1′ has the appropriate playback file or a playback file with the appropriate content, whether it be received from the mobile terminal 8 or other otherwise, the CPU 17′ synchronises the playback file with the bookmark file (step L9), creates an extracted content file (step L10), plays back the extracted content (step L11) and saves the extracted content file in storage 19′ (step L12). [0282] It will be appreciated that many modifications may be made to the embodiments hereinbefore described. For example, the content may comply additionally or alternatively to other standards. The content may be encoded or encrypted.
