Description:
CROSS-REFERENCE TO RELATED APPLICATIONS  
       [0001]     This application is based upon and claims the benefit of priority from prior Japanese Patent Application No. 2005-132052, filed Apr. 28, 2005, the entire contents of which are incorporated herein by reference.  
       BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     The present invention relates to a content managing technique for improving convenience when transmitting and receiving via a network audio video (AV) content compressed and encoded from or to so called digital consumer electronic appliance products for household use, such as a digital versatile disk (DVD) recorder, a hard disk drive (HDD) video recorder, a personal computer, a personal digital assistant (PDA), or a cellular phone, for example.  
         [0004]     2. Description of the Related Art  
         [0005]     In recent years, networking of so called digital consumer electronic appliance products, such as DVD recorders or HDD video recorders, has progressed remarkably. For example, as is apparent from the efforts of the Digital Living Network Alliance (DLNA), great attention has been focused on connecting a plurality of digital consumer electronic appliance products via a network and exchanging AV content between them.  
         [0006]     When content is transferred, two large problems exist in view of intra-equipment compatibility: (1) compatibility of protocols for use in transfer; and (2) a compression format of content to be transferred.  
         [0007]     The DLNA has established a guideline in order to solve these problems. With respect to a compression format of item (2), compatibility is guaranteed by using a method for “specifying an essential format”. The problem which occurs here is that, in general, between a stationary household device and a mobile device for portable use, different compression formats are often used in view of processor capacity, memory consumption, power consumption or the like. For example, in terms of video content, a stationary device can conform to MPEG-2, and a mobile device can conform to MPEG-4.  
         [0008]     In such a situation, for example, when an attempt is made to download and view video content which exists in a (stationary) household device by using a mobile device, it is necessary to convert MPEG-2 content to MPEG-4 content, and then, transfer the converted content. In the case where a household device includes a transcoder which converts MPEG-2 to MPEG-4, it is possible to achieve conversion using only the two devices of the parties concerned.  
         [0009]     On the other hand, where the household device fails to include a transcoding function from MPEG-2 to MPEG-4, a third relay device can be used over a network to perform transcoding. This is a particularly effective technique in a closed world, such as a household network, where sharing the transcoding function or resources can be readily achieved.  
         [0010]     However, where content is directly exchanged between the parties and where content is exchanged while a relay device is-interposed, there still remains a general problem that a predetermined amount of processing time is required for this transcoding.  
         [0011]     In addition, as one technique for enhancing responsiveness, a method has been proposed for storing content converted by the transcoder in a cache after being converted (refer to Jap. Pat. Appln. KOKAI Publication No. 2004-526227, for example). According to this technique, for example, with respect to second and subsequent requests, it becomes possible to enhance system responsiveness.  
         [0012]     The system described in the Jap. Pat. Appln. KOKAI Publication No. 2004-526227 is tailored for an unspecified number of users. For example, a so called majority rule is established for satisfying many more users from among all the users, for example, for determining the content stored in a cache after being converted using a Least Recently Used algorithm.  
         [0013]     However, in digital consumer electronic appliance products for household use, it is necessary to properly respond to a specialized demand of each user.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0032]     Embodiments will be described with reference to the accompanying drawings.  
       First Embodiment  
       [0033]     A first embodiment of the present invention will be described.  FIG. 1  is a view showing a network configuration of a in-house network system according to the first embodiment.  
         [0034]     As shown in  FIG. 1 , the in-house network system according to the first embodiment includes a stationary electronic apparatus  1  such as a DVD recorder, for example, and an electronic apparatus  2  for portable use such as a cellular phone being connected via a wireless LAN. Multiple content such as program data obtained by recording a television broadcast, for example, is stored in the electronic apparatus  1  installed in a living room of each house. A user can view the content stored in this electronic apparatus  1  in any place such as one&#39;s own room and at any time by using one&#39;s own electronic apparatus  2 .  
         [0035]     As used herein, the electronic apparatus  1  stores the content in accordance with the MPEG-2 compression format and has a transcoding function of transcoding the compression format of the content to a different compression format such as MPEG-4 or WMV. On the other hand, it is presumed that the electronic apparatus  2  has a content reproducing function capable of reproducing only the content in the MPEG-4 compression format. Namely, in this in-house network system, when content is transferred from the electronic apparatus  1  to the electronic apparatus  2 , transcoding of the content is executed by the electronic apparatus  1 . Even in an environment which requires this transcoding, control is made so as not to degrade the user&#39;s operability.  FIG. 1  shows the electronic apparatus  1  and the electronic apparatus  2  connected to each other via any wireless or wired technology such as IEEE 802.11, IEEE 802.3 or Bluetooth (registered trademark) for example. In addition, when content is transferred between stationary electronic apparatuses as well as when content is transferred to a mobile device for portable use, the present invention is effective in the case where there is a need for transcoding.  
         [0036]      FIG. 2  is a view showing a system configuration of the electronic apparatus  1 . As shown in the figure, the electronic apparatus  1  has a control unit  10 , a recording unit  11 , a transcoding unit  12 , a judging unit  13 , a network connecting unit  14 , and a content transmitting unit  15 .  
         [0037]     The control unit  10  is responsible for overall control of this electronic apparatus  1 , and is achieved by an MPU or the like, for example. The recording unit  11  is achieved by a hard disk drive (HDD) or the like, for example, and stores a variety of data including content such as the program data obtained by recording a television program. The transcoding unit  12  is an encoding type converter device (transcoder) which converts content from one compression format to another.  
         [0038]     When the transcoded content is transferred to another device via a network, the judging unit  13  judges whether or not to store new content produced after being transcoded in the recording unit  11 . In order to perform this judgment, the judging unit  13  comprises a judging table  131  described later. The network connecting unit  14  can employ any wired or wireless technology. Further, this network connecting unit  14  includes Universal Plug-and-Play (UPnP) capability. In addition, the content transmitting unit  15  controls transmission of the new content produced by the transcoding unit  12  to another device via a network.  
         [0039]     A general flow of operation will be described with reference to  FIGS. 3A and 3B  with respect to how a list of content reserved in one device (server) is acquired and referred to from another device (client).  
         [0040]     Assume that the client has a content reproducing function capable of reproducing only content in accordance with the MPEG-4 compression format. On the other hand, presume that the server has content A which conforms to the MPEG-2 compression format and content B which conforms to the MPEG-4 compression format. Under such a presumption,  FIG. 3A  shows a flow of operation in the case where the server fails to have a transcoding function from MPEG-2 to MPEG-4; and  FIG. 3B  shows a flow of operation in the case where the server has the transcoding function.  
         [0041]     First, the client makes a query to the server as to what kinds of content can be provided (A 1  of  FIG. 3A ). In response to this query, the server which does not have the transcoding function returns to the client the fact that the MPEG-2 compression format content A and the MPEG-4 compression format content B can be provided (A 2  of  FIG. 3A ). On the other hand, in response to this query, the server which has the transcoding function returns to the client the fact that the MPEG-4 compression format version of content A can be provided in addition to the two pieces of content actually possessed (B 2 ′ of  FIG. 3B ).  
         [0042]     Upon the receipt of the response from the server, the client displays a list of the MPEG-4 compression format content which can be reproduced by the client. As a result, in the case of  FIG. 3A , only content B is displayed in listings (A 3  of  FIG. 3A ). In the case of  FIG. 3B , both content A and B are displayed in listings (B 3 ′ of  FIG. 3B ).  
         [0043]     Upon the receipt of this listing (B 3 ′ of  FIG. 3B ), when the user selects content A, a transfer request relevant to the MPEG-4 compression format content A is sent from the client to the server (B 4  of  FIG. 3B ). Then, a transcoding process occurs at the server side (B 5  of  FIG. 3B ), and content A after being transcoded is transferred (B 6  of  FIG. 3B ).  
         [0044]     Thus, in the case where the content stored in the recording unit  11  has been requested by electronic apparatus  2 , corresponding to the client in  FIG. 3B , in a compression format which is different from the compression format in which the content is stored, the electronic apparatus  1  having the transcoding unit  12  and corresponding to the server shown in  FIG. 3B  executes transcoding for responding to this request. Then, the electronic apparatus  1  according to the present embodiment uses the judging unit  13  to properly manage the user&#39;s content after it is transcoded.  
         [0045]      FIG. 4  shows a specific example of a judging table  131  which is included in the judging unit  13 . As shown in the figure, the judging table  131  consists of three fields such as an “input format”, an “output format”, and a “judgment result”. According to this judging table  131 , where the content stored in the recording unit  11  is in the MPEG-2 compression format and is transcoded to the MPEG-4 compression format, the MPEG-4 compression format content is stored in the recording unit  11 . In addition, where the content stored in the recording unit  11  is in the MPEG-2 compression format and is transcoded to a WMV compression format, the WMV compression format content is discarded without being stored. Similarly, where the content stored in the recording unit  11  is in the MP3 compression format and is transcoded to the AAC compression format, the AAC compression format content is stored in the recording unit  11 .  
         [0046]     As described above, with the electronic apparatus  1  of the present embodiment, it becomes possible to carry out a variety of operations for each user in accordance with the judging unit  131 , for example, by storing only when a large amount of time is required for transcoding, for further reuse; by storing content in frequently used compression formats after being transcoded; or properly coping with free space of the recording unit  11  at the time of storage. The judging table  131  may be produced by any existing method, for example, by preparing a setup screen for a user interface. In addition, apart from the table produced by the user, the judging unit  13  may produce the table automatically by using a statistic technique so as to record a transfer history as to what pattern of transcoding has been carried out. This approach can be used to store the content after being transcoded, which has a pattern of being used more frequently in excess of a threshold value.  
         [0047]     In addition, instead of using judging table  131 , when transcoding has been carried out from one compression format to another compression format, as shown in  FIG. 5 , the control unit  10  can make a query (C 1  of  FIG. 5 ) to a content request source as to whether or not to store the content after being transcoded every time such transcoding is carried out, whereby the control unit  10  may control whether or not the content is stored after being transcoded according to a response. By using this procedure, it becomes possible to manage content after being transcoded according to the user&#39;s request.  
         [0048]      FIG. 6  is a flowchart showing a procedure for transferring content in a in-house network system according to the present embodiment.  
         [0049]     Where the content-stored in the stationary electronic apparatus  1  is viewed by using the electronic apparatus  2  for portable use, first, the electronic apparatus  2  serving as an information receiver device (client) and the electronic apparatus  1  serving as an information transmitter device (server) are connected to each other via a network (step A 1 ). When this network connection is completed, the electronic apparatus  2  which is the information receiver device refers to a list of content stored in the electronic apparatus  1  (step A 2 ). Then, the electronic apparatus  2  which is the information receiver device selects desired content from the list of content referred to (step A 3 ).  
         [0050]     Upon the receipt of this selection, the electronic apparatus  1  which is the information transmitter device judges whether or not transcoding is required upon transmission of the content (step S 4 ). If this transcoding is not required (NO in step A 4 ), the electronic apparatus  1  which is the information transmitter device executes transmission of the selected content (step A 5 ). In addition, when the transcoding is required (YES in step A 4 ), the electronic apparatus  1  which is the information transmitter device executes transcoding (step A 6 ), and transmits the content after being transcoded to the electronic apparatus  2  which is the information receiver device (step A 7 ).  
         [0051]     When this transcoding has been carried out, the electronic apparatus  1  which is the information transmitter device judges whether or not there is a need for storing the content after being transcoded (step A 8 ). Then, in the case where the judgment result is affirmative (YES in step A 8 ), the electronic apparatus  1  which is the information transmitter device stores the content after transcoded (step A 9 ). On the other hand, in the case where the being judgment result is negative (NO in step A 8 ), the content after being transcoded is discarded (step A 10 ).  
         [0052]     As described above, according to the in-house network system of the present embodiment, the content after being transcoded is managed according to the user&#39;s request.  
       Second Embodiment  
       [0053]     A second embodiment of the present invention will be described.  FIG. 7  is a view showing a system configuration of an electronic apparatus  1  in the second embodiment. In the figure, the same constituent elements of the electronic apparatus  1  in the first embodiment described previously with respect to  FIG. 2  are designated by the same reference numerals.  
         [0054]     In this electronic apparatus  1  according to the second embodiment, a preprocessing content selecting unit  16  is further provided as shown in  FIG. 7 . When content is transferred to an electronic apparatus  2 , the electronic apparatus  1  according to the first embodiment described previously executes transcoding, and judges whether or not to store the content after being transcoded. However, when given content is stored in the recording unit  11 , the electronic apparatus  1  according to the second embodiment judges whether or not to execute transcoding when the content is stored, and stores in advance both the original content and the content after being transcoded (before a request from the electronic apparatus  2 ). In order to perform this judgment, the preprocessing content selecting unit  16  comprises a preprocessing table  161 .  
         [0055]      FIG. 8  shows a specific example of the preprocessing table  161  provided in the preprocessing content selecting unit  16 . As shown in the figure, the preprocessing table  161  consists of two fields, i.e., a “content type” and a “preprocessing condition”. Meta-information in extensible markup language (XML) format is provided as accessories to each piece of content, as shown in  FIG. 9 . Thus, an arbitrary tag and its value are defined as a selection condition, whereby content matching a user&#39;s preference can be selected from among a number of piece of content.  
         [0056]     Namely, in this electronic apparatus  1  according to the second embodiment, when given content is stored in the recording unit  11 , the preprocessing content selecting unit  16  judges whether the content matches the user&#39;s preference. When the judgment result is affirmative, the judgment unit  13  judges whether or not transcoding is required. For example, when the judging table  131  is as shown in  FIG. 4  and the compression format of the content targeted for processing is MPEG-2, a search is made for an entry indicating that the “input format” in the judging table  131  is “MPEG-2” and the “judgment result” is “record”. When such an entry is detected, it is determined that a transcode for the compression format of that “output format” is executed.  
         [0057]     As described above, according to the in-house network system of the present embodiment, more proper management is achieved by making a selection matching the user&#39;s preference, and then, transcoding and storing it in advance.  
       Third Embodiment  
       [0058]     Now, a third embodiment of the present invention will be described here.  FIG. 10  is a view showing a network configuration of an in-house network system according to the present embodiment.  
         [0059]     In the in-house network system according to the first and second embodiments described previously, the stationary electronic apparatus  1  has a transcoding function. Thus, the exchange of content between the electronic apparatus  1  and an electronic apparatus  2  for portable use is directly carried out between the parties concerned. In contrast, in the in-house network system according to the third embodiment, an electronic apparatus  3  having a transcoding function is interposed to carry out the exchange of the content between the electronic apparatus  1  and the electronic apparatus  2 .  
         [0060]     For example, when the content stored in the electronic apparatus  1  is viewed by using the electronic apparatus  2 , if transcoding of the content is required, the electronic apparatus  3  which relays transfer of the content integrally executes this transcoding.  
         [0061]     If this electronic apparatus  3  comprises a function identical to the electronic apparatus  1  according to the first embodiment, the content after being transcoded is stored as required. In addition, if the electronic apparatus  3  comprises a function identical to the electronic apparatus  1  according to the second embodiment, when new content is stored in any electronic apparatus  1 , it becomes possible to acquire the content in advance as required, and then, transcode and store it. Further, in this in-house network system according to the third embodiment, the electronic apparatus  3  which relays transmission of content is connected to a plurality of electronic apparatuses  1  via a network. Thus, all of the recording units  11  provided in these plurality of electronic apparatuses  1  are utilized as a storage place of the content after being transcoded.  
         [0062]      FIG. 11  is a view showing a system configuration of the electronic apparatus  3 . As shown in  FIG. 11 , the electronic apparatus  3  has: a control unit  30 ; a recording unit  31 ; a transcoding unit  32 ; a judging unit  33 ; a network connecting unit  34 ; a content transmitting and receiving unit  35 ; and a content recording destination selecting unit  36 . Among them, the control unit  30  to the network connecting unit  34  correspond to the control unit  10  to the network connecting unit  14  of the electronic apparatus  1  in the first embodiment described previously, shown in  FIG. 2 . In addition, the content transmitting and receiving unit  35  has a content receiving function added to the content transmitting unit  15 . In addition, the content recording destination selecting unit  35  is a constituent element specific to the electronic apparatus  3  according to the third embodiment, and makes a selection of a destination for storing the content after being transcoded.  
         [0063]     In this third embodiment, the electronic apparatus  3  is defined as a server; and the electronic apparatus  1  and the electronic apparatus  2  are defined as clients. A general flow of operation will be described with reference to  FIG. 12  with respect to how an electronic apparatus  3  based network connection is made.  
         [0064]     Consider a case in which any electronic apparatus  2  (client A) is started up, and an attempt is made to make a network connection in order to utilize the content stored by a peripheral device. At this time, client A first outputs a message for making a search for peripheral devices (D 1  of  FIG. 12 ). Each device having received this message returns to the client a message notifying the presence of such a peripheral device (D 2  of  FIG. 12 ).  
         [0065]     Among these response messages, a specific tag (&lt;transcoder&gt;) is included in a response message returned by the given electronic apparatus  3  which is a server. If this tag is found, the client A interprets that a device having returned this response message is a server, and all the content can be acquired from the server. Subsequently, even if the client A receives a response message from client B, the client A makes a query to this server as to what kinds of content can be provided (D 3  of  FIG. 12 ).  
         [0066]     Having received the query from the electronic apparatus  2  through such procedures, the electronic apparatus  3  returns to the client a list of compression format content which can be transcoded by a transcoding function incorporated in the server in addition to the compression format content actually stored by each of the electronic apparatuses  1 . Where transfer of the content is relayed while transcoding is carried out, the electronic apparatus  3  executes the exchange as shown in  FIG. 13  with the electronic apparatus  2 .  
         [0067]     First, the control unit  30  of the electronic apparatus  3  makes a query as to whether or not to store the content after being transcoded (El of  FIG. 13 ). If the response is affirmative (E 2  of  FIG. 13 ), the content recording destination selecting unit  36  then makes a query as to where to store the content after being transcoded (E 3  of  FIG. 13 ). When any electronic apparatus  1  has been specified as a destination of storing the content (E 4  of  FIG. 13 ), the content after being transcoded is transferred to the specified electronic apparatus  1 , and then, the transferred content is stored in the recording unit  11  (E 5  of  FIG. 13 ).  
         [0068]      FIG. 14  is a flowchart showing a procedure for transferring content in the in-house network system according to the present embodiment.  
         [0069]     In the case where the content stored in a stationary electronic apparatus  1  is viewed by using an electronic apparatus  2  for portable use, first, the electronic apparatuses  1  and  2  serving as an information transmitter device and an information receiver device (client) and the electronic apparatus  3  serving as an information relay device (server) are connected to each other via a network (step B 1 ). When this network connection is completed, the electronic apparatus  2  which is the information receiver device refers to a list of content stored in the electronic apparatus  1  and the electronic apparatus  3  (step B 2 ). Then, the electronic apparatus  2  which is the information receiver device selects desired content from the list of content referred to (step B 3 ).  
         [0070]     Upon the receipt of this selection, first, the electronic apparatus  3  which is the information relay device checks to see if the content exists on that device (step B 4 ). If the check result is negative (NO in step B 4 ), the content is acquired from the electronic apparatus  1  which stores the content (step B 5 ).  
         [0071]     Next, the electronic apparatus  3  which is the information relay device judges whether or not transcoding is required upon transmission of the content (step B 6 ). If transcoding is not required, (NO in step B 6 ), the electronic apparatus  3  executes transmission of the selected content (step B 7 ). If transcoding is required (YES in step B 6 ), the electronic apparatus  3  which is the information relay device executes the transcoding (step B 8 ), and transmits the content after being transcoded to the electronic apparatus  2  which is the information receiver device (step B 9 ).  
         [0072]     When this transcoding has been carried out, the electronic apparatus  3  which is the information relay device judges whether or not there is a need for storing the content after being transcoded (step B 10 ). Then, in the case where the judgment result is affirmative (YES in step B 10 ), the electronic apparatus  3  which is the information relay device determines a destination for storing the content after being transcoded (step B 11 ). When the storage destination is the information relay device (YES in step B 11 ), the content after being transcoded is stored in the information relay device (step B 12 ). If the storage destination is not the information relay device (NO in step B 11 ), the content after being transcoded is transferred to the storage destination (step B 13 ), and the content after being transcoded, remaining on the information relay device, is discarded (step B 14 ). In addition, in the case where it is judged that there is no need for storing content after being transcoded (NO in step B 10 ), the content after being transcoded is discarded (step B 14 ).  
         [0073]     As described above, according to the in-house network system of the present embodiment, it becomes possible to utilize all of the electronic apparatuses connected via a network as destinations of storing the content after being transcoded.
