Abstract:
Systems, methods, apparatuses, and computer readable media may be configured for establishing at least one session for delivery of multimedia. In an aspect, a first transmission of data fragments of a first component and a second transmission of data fragments of a second component may be transmitted and synchronized for presentation. If an inactivity event is detected the session may be maintained while reducing bandwidth consumption.

Description:
BACKGROUND 
       [0001]    Consumers are increasingly demanding rich multimedia content that requires distribution of a large amount of data over a network. Multimedia content may provide consumers with video content, audio content, and data content. Multimedia content is typically delivered as a composite asset that includes video, audio, and data. 
         [0002]    Existing systems can be wasteful of bandwidth resources, for example, delivering portions of the multimedia content that a consumer does not desire to receive (e.g., audio in a language the consumer does not speak), or delivering multimedia content almost indefinitely, unless a consumer takes some affirmative action to end delivery. Transporting of undesired or unneeded content is wasteful, and may result in degraded performance. 
         [0003]    Accordingly, there remains a need to improve bandwidth utilization, and to balance user demands for multimedia content against network performance. 
       SUMMARY 
       [0004]    The following presents a simplified summary in order to provide a basic understanding of some aspects as described herein. The summary is not an extensive overview of all aspects. It is neither intended to identify key or critical elements nor to delineate the scope of the present disclosure. The following summary merely presents various example concepts in a simplified form as a prelude to the more detailed description below. 
         [0005]    In some embodiments, systems, methods, apparatuses, and computer readable media may be configured for establishing at least one session for delivery of multiple components of a multimedia content item. For example, first and second transmissions of data fragments corresponding to first and second components, may be received, synchronized, and presented for rendering of the multimedia content item. An inactivity event may be identified subsequent to the rendering; and, subsequent to the identifying of the inactivity event, a session may be maintained in an active state. In some examples, delivery of a first transmission of data fragments may be stopped, or a lower bandwidth version of the first component may be requested and/or provided. 
         [0006]    This summary is not intended to identify critical or essential features of the disclosures herein, but instead merely summarizes certain features and variations thereof. Other details and features will also be described in the sections that follow.

       [0014]    In the following description of the various embodiments, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration various embodiments in which the disclosure may be practiced. It is to be understood that other embodiments may be utilized and structural and functional modifications may be made without departing from the scope and spirit of the present disclosure. 
         [0015]      FIG. 1  illustrates an example information distribution network  100  in which many of the various features described herein may be implemented. The illustrated information distribution network is only one example of a network and is not intended to suggest any limitation as to the scope of use or functionality of the disclosure. The illustrated network should not be interpreted as having any dependency or requirement relating to any component or combination of components in an information distribution network. 
         [0016]    Network  100  may be a telecommunications network, a multi-service operator (MSO) network, a cable television (CATV) network, a cellular network, a wireless network, an optical fiber network, a coaxial cable network, a hybrid fiber-coaxial (HFC) network, or any other type of information distribution network or combination of networks. For example, network  100  may be a cellular broadband network communicating with multiple communications access points, such as wireless communications tower  130 . In another example, network  100  may be a coaxial system comprising a cable modem termination system (CMTS) communicating with numerous gateway interface devices (e.g., gateway interface device  111  in example home  102   a ). In another example, the network  100  may be a fiber-optic system comprising optical fibers extending from an optical line terminal (OLT) to numerous optical network terminals (ONTs) communicatively coupled with various gateway interface devices. In another example, the network  100  may be a digital subscriber line (DSL) system that includes local office  103  communicating with numerous gateway interface devices. In another example, network  100  may be an HFC network in which Internet traffic is routed over both optical and coaxial communication paths to a gateway interface device in or near a user&#39;s home. Various aspects of the disclosure may operate on one or more of the networks described herein or any other network architectures now known or later developed. 
         [0017]    Network  100  may use a series of interconnected communication links  101  (e.g., coaxial cables, optical fibers, wireless links, etc.) to connect premises such as homes  102  or other user environments to local office  103 . Communication links  101  may include any wired communication links, wireless communication links, communications networks, or combinations thereof. For example, portions of communication links  101  may be implemented with fiber-optic cable, while other portions of communication links  101  may be implemented with coaxial cable. Communication links  101  may also include various communications components such as splitters, filters, amplifiers, wireless components, and other components for communicating data. Data may include, for example, internet data, voice data, weather data, media content, and any other information. Media content may include, for example, video content, audio content, media on demand, video on demand, streaming video, television programs, text listings, graphics, advertisements, and other content. A media content item may represent an individual piece of media content, such as a particular movie, television episode, online video clip, song, audio recording, image, or any other data. In some instances, a media content item may be fragmented into segments, such as a plurality of two-second video fragments that may be separately addressed and retrieved. 
         [0018]    Local office  103  may transmit downstream information signals onto communication links  101 , and premises such as home  102  may receive and process those signals. In certain implementations, communication links  101  may originate from local office  103  as a single communications path, and may be split into any number of communication links to distribute data to homes  102  and various other destinations. Although the term home is used by way of example, homes  102  may include any type of user environment, such as single family homes, apartment complexes, businesses, schools, hospitals, parks, and other environments and combinations of environments. 
         [0019]    Local office  103  may include interface  104 , which may be a computing device configured to manage communications between devices on the network of communication links  101  and backend devices, such as server  105 , computing device  106  (e.g., server), and server  107 . For example, interface  104  may be a cable modem termination system (CMTS). The termination system may be as specified in a standard, such as, in an example of an HFC-type network, the Data Over Cable Service Interface Specification (DOCSIS) standard, published by Cable Television Laboratories, Inc. The termination system may be configured to transmit data over one or more downstream channels or frequencies to be received by various devices, such as modems in homes  102 , and to receive upstream communications from those modems on one or more upstream frequencies. 
         [0020]    Local office  103  may include one or more network interfaces  108  for communicating with one or more external networks  109 . One or more external networks  109  may include, for example, one or more telecommunications networks, Internet Protocol networks, cellular communications networks (e.g., Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA), and any other 2nd, 3rd, 4th and higher generation cellular communications networks), cellular broadband networks, radio access networks, fiber-optic networks, local wireless networks (e.g., Wi-Fi, WiMAX), satellite networks, and any other networks or combinations of networks. 
         [0021]    Local office  103  may include a variety of servers that may be configured to perform various functions. Local office  103  may include one or more push servers  105  for generating push notifications to deliver data, instructions, or both to devices that are configured to detect such notifications. Local office  103  may include one or more servers  106  configured to provide content (e.g., media content) to devices. Computing device  106  may be a network server or content server storing content items. Local office  103  may include one or more application servers  107 . 
         [0022]    Homes  102  such as home  102   a  may include an interface  120 , which may include device  110 , for communicating on communication links  101  with local office  103 , one or more external networks  109 , or both. For example, device  110  may be a coaxial cable modem (for coaxial cable links  101 ), a broadband modem (for DSL links  101 ), a fiber interface node (for fiber-optic links  101 ), or any other device or combination of devices. In certain implementations, device  110  may be a part of, or communicatively coupled to, gateway interface device  111 . Gateway  111  may be, for example, a wireless router, a set-top box, a computer server, or any other computing device or combination. 
         [0023]    Gateway interface device  111  may be any computing device for communicating with device  110  to allow one or more other devices in example home  102   a  to communicate with local office  103 , one or more external networks  109 , or other devices communicatively coupled thereto. Gateway  111  may include local network interfaces to provide communication signals to client devices in or near example home  102   a , such as television  112 , set-top box  113 , personal computer  114 , laptop computer  115 , wireless device  116  (e.g., a wireless laptop, a tablet computer, a mobile phone, a portable gaming device), vehicular computing system  117  (e.g., a mobile computing system, navigation system, or entertainment system in an automobile, marine vessel, or aircraft) and any other device. 
         [0024]      FIG. 2  illustrates general hardware elements and software elements that can be used to implement any of the various computing devices and/or software discussed herein. Device  200  may include one or more processors  201 , which may execute instructions of a computer program to perform any of the functions and steps described herein. The instructions may be stored in any type of computer-readable medium or memory to configure the operation of the processor  201 . For example, instructions may be stored in a read-only memory (ROM)  202 , random access memory (RAM)  203 , removable media  204 , such as a Universal Serial Bus (USB) drive, compact disk (CD) or digital versatile disk (DVD), hard drive, floppy disk drive, or any other desired electronic storage medium. Instructions may also be stored in hard drive  205 , which may be an internal or external hard drive. 
         [0025]    Device  200  may include one or more output devices, such as a display  206 , such as an external monitor or television, and may include one or more output device controllers  207 , such as a video processor. In some embodiments, device  200  may include one or more user input devices  208 , such as a remote control, keyboard, mouse, touch screen, microphone, or any other input device. 
         [0026]    Device  200  may also include one or more network interfaces, such as network input/output (I/O) interface  210  to communicate with an external network  209 . The network interface may be a wired interface, wireless interface, or a combination of the two. In some embodiments, network I/O interface  210  may include a cable modem, and network  209  may include the communication links  101  shown in  FIG. 1 , one or more external networks  109 , an in-home network, a provider&#39;s wireless, coaxial, fiber, or hybrid fiber/coaxial distribution system (e.g., a DOCSIS network), or any other desired network. 
         [0027]      FIG. 3  illustrates example aspects of computing device  106  storing multimedia content items as discrete components in accordance with example embodiments. Computing device  106  may include a memory  320  for storing one or more multimedia content items. A multimedia content item may be a compilation of components, such as, for example, audio, video and ancillary data. 
         [0028]    Each multimedia content item may be stored as discrete components, rather than as a single asset. For example, a multimedia content item may include multiple video components  304 , multiple audio components  306 , multiple data components  308 , and other components  311 . In an embodiment, other components  311  may be signals, messages, or other envisioned or future developed data. Each video component  304  may correspond to a different version of video for the multimedia content item. For example, a first version may be high definition (HD) video, a second version may be a left eye view for three dimensional (3D) video, a third version may be a right eye view for three dimensional (3D) video, and a fourth version may be standard definition video. Video components may also be different formats of video, where a first component may be a large version of video and a second version may be a small-format or thumbnail version. In an example, small-format versions may be used for presenting a mosaic of the video using multiple display screens, where each screen presents a different portion of full-screen video. In the example shown in  FIG. 3 , memory  320  stores multimedia content items 1 and 2. Multimedia content item 1 includes video components  304 A-B, and multimedia content item 2 includes video components  304 C-E. 
         [0029]    Each audio component  306  may correspond to a different version of audio for a multimedia content item. For example, if the multimedia content item is of a sporting event, a first version may be audio of a home team&#39;s television announcer, a second may be audio of a home team&#39;s radio announcer, a third version may be audio of a visiting team&#39;s television announcer, and a fourth version may be audio of a visiting team&#39;s radio announcer. In another example, a first version of audio may correspond to a left channel and a second version may correspond to a right channel, and so forth. Audio components may also correspond to different languages. In the example shown in  FIG. 3 , multimedia content item 1 includes audio components  306 A-C, and multimedia content item 2 includes audio components  306 D-E. 
         [0030]    Each data component  308  may include data provided from one or more sources. A data component may, for example, support interactive applications, alternate languages, closed captioning, etc. For example, a first data component may include real-time statistics of a sporting event, a second data component may include closed captioning text, a third data component may include comments posted on a social networking website, a fourth data component may include data streamed from a webserver (e.g., real-time stock quotes). In the example shown in  FIG. 3 , multimedia content item 1 includes data components  308 A-B, and multimedia content item 2 includes data components  306 C-D. 
         [0031]    To provide a multimedia content item, computing device  106  may establish a session with device  110  (or device  401 ,  FIG. 4 ). Device  110  may forward data fragments received via the session to an end user device, such as, for example, television  112 , wireless device  116 , for presentation to the user. Device  110  may also be the end user device, or may be integrated into the end user device. The following describes device  110  as being the end user device, however the functionality below attributed to device  110  may be divided between device  110  and at least one other device (e.g., wireless device  116 ). 
         [0032]    A session may transport multiple transmissions (e.g. multiple streams) of data fragments, where each transmission corresponds to one component. By separating multimedia content items into discrete components, computing device  106  may establish one transmission per component, thereby only delivering desired components of the multimedia content item. This may result in savings of bandwidth, and may permit computing device  106  to halt sending of a transmission for a particular component, or sending a lower bandwidth version, if inactivity is detected. Further, separating multimedia content items into discrete components advantageously permits a single multimedia content item to be stored on, and delivered from, multiple servers  106 . Data fragments of each component may include synchronization information to permit synchronizing of the video, audio, and data upon receipt. 
         [0033]      FIG. 4  illustrates an example signaling diagram of communications between computing device  106  and device  401  in accordance with example embodiments. Device  401  may be an interface  120  or another device such as an end-user device (e.g. device  110 ). Device  401  may communicate a request  402  that requests interface data such as graphical user interface (GUI) data, or application program interface data from computing device  106 . The interface data may indicate available multimedia content items, as well as the components associated with each item. Computing device  106  may respond with a response message  404  that includes the interface data. In other examples, computing device  106  may periodically communicate the interface data and device  401  may tune to a particular channel, decode a particular data transmission, etc., to receive the interface data. Subsequent to receiving the GUI data, device  401  may process the GUI data and present a multimedia interface. A device other than device  401  (e.g., wireless device  116 ) may display the multimedia interface instead of or in addition to device  401 . 
         [0034]      FIG. 5  illustrates an example multimedia interface such as a multimedia graphical user interface in accordance with example embodiments. Multimedia GUI  500  may present one or more multimedia content items  502 A-D that are available for presentation. Different users may want versions of a multimedia content item, and some may need no more than a subset of the components. Multimedia GUI  500  may assist the user is selecting which components of a multimedia content item are desired. 
         [0035]    Upon selection of a particular multimedia content item, multimedia GUI  500  may present components available for selection. In example, user may provide input to device  401  to select multimedia content item  502 B. Multimedia GUI  500  may then display component selection field  504 . Component selection field  504  may permit selection between one or more video components in field  506 , audio components in field  508 , and data components in field  510  associated with the selected multimedia content item. More than one component may be selected within each of fields  506 ,  508 , and  510 . For example, a user may select both video component 1 and video component 2 in video selection field  506 . Component selection field  504  may also permit selection in fields  512 ,  514 , and  516  of what device is to receive each of the selected components. For example, a user may select to have video component 1 provided to first and second devices, video component 2 provided to a third device, and not to have video component 3 provided to any device. In another example, a user may select to only receive audio component 1, and not to receive any of the video components or data components. A user may also revise their selections in Multimedia GUI  500  over time. For example, a user may initially select English audio, and midway through presentation of the multimedia content item, may change the selection to be Spanish audio. 
         [0036]    In an example with reference to  FIGS. 1 and 5 , Multimedia GUI  500  may be presented by laptop computer  115  that receives GUI data forwarded from device  401  via gateway  111 . Using an input device of laptop computer  115 , a user may select to have video component 1 provided to television  112  and laptop computer  115 , video component 2 provided to wireless device  116 , and not to have video component 3 provided to any device. For instance, television  112  may present 3D HD video and laptop computer  115  may present standard definition video. A user may select to have audio component 1 provided to laptop computer  115  and audio component 2 provided to wireless device  116 . For instance, laptop computer  115  may present English audio and wireless device  116  may present Mandarin audio. A user may select to have data component 1 provided to laptop computer  115 , and not to have data component 2 provided to any device. 
         [0037]    Referring again  FIG. 4 , device  401  may communicate a multimedia request  406  to computing device  106  based on selections received using multimedia GUI  500 . Multimedia request  406  may include a listing of identifiers of the selected components. For example, request  406  may identify only a single audio component, or, for 3D high definition (HD), may identify a video component, an advanced audio component, and audio components for multiple languages. 
         [0038]    Subsequent to receiving request  406 , computing device  106  may then communicate with device  401  to establish a session. Computing device  106  may include, for example, a session resource manager (SRM). Each session may transport one or more data transmissions. For example, if a user selected two video components and one audio component, computing device  106  may establish a session to transport three data transmissions. To establish a session, computing device  106  may communicate a network location from which device  401  is to obtain a component. The network location may be a network address of a device other than the computing device  106 , to permit establishing of sessions with multiple servers  106  that collectedly provide components of a single multimedia content item. The components may be available from multiple locations to enable efficient use of storage and network transmission resources. 
         [0039]    After a session is established, device  401  may receive transmissions of data fragments for each of the components. A data fragment may be a packet, a cell, a frame, or other manner of transporting a portion of data from a source to a destination over a network. Each data fragment may include synchronization information and a transmission identifier. For example, fragments of each of the audio, video, and data components may include synchronization information specifying a time stamp. Device  401  may reassemble the components for presentation based on data fragments of the different components having a time stamp that includes a common value. Device  401  may also cache a predetermined amount of data prior to presentation to reduce any issues with latency, problems with a network transmission path delivering data from computing device  106  to device  401 , and to allow for inter-fragment skew when the fragments are being synchronized for presentation. 
         [0040]    The transmission identifier may identify to which transmission a data fragment belongs. For example, if a session transports a video transmission, an audio transmission, and a data transmission, the video transmission may have a first identifier, the audio transmission may have a second identifier, and the data transmission may have a third identifier. Device  401  may use the transmission identifier to distinguish between the transmissions. By transporting only the components the user requests, the amount of bandwidth used to transport the multimedia content item may be reduced. 
         [0041]    To efficiently use network bandwidth, device  401  (or other device, e.g., laptop computer  115 ) may monitor for inactivity events while presenting the multimedia content item. An inactivity event may be a determination that a user is not viewing or not listening to the multimedia content item currently being provided, or that the user is using the device  401  to do something besides viewing or listening to the multimedia content item. In an example, device  401  may include an activity timer for monitoring activity within a predetermined amount of time and may identify an inactivity event at the expiration of the timer. Device  401  may reset the timer each time that a reset trigger is identified. Example reset triggers may include a user responding to a prompt generated by the multimedia content item, changing a volume setting, etc. Device  401  may be controlled by a remote control. The remote control may include an accelerometer (or other motion detection sensor) to determine user presence and activity. Device  401  may periodically receive motion data from the remote control and, if the data indicates a predetermined amount of motion, device  401  identify such movement as an activity event and reset the timer. Device  401  may also be coupled to other types of motion detectors (e.g., infrared, laser, etc.) to determine user presence and activity. Additional activities may include program selection or a change in a setting such as a channel setting. 
         [0042]    When multiple devices are being used to present a multimedia content item, activity detected at any of the devices may be used reset the activity timer. For example, and with reference to  FIG. 1 , a video component may be presented by a wireless device  116  and by laptop computer  115 . Laptop computer  115  may detect activity and communicate activity data to device  401  that resets the activity timer. Activity timer may be implemented at device  401  or at other devices, such as laptop computer  115 , desktop computer  114 , wireless device  116 , etc. 
         [0043]    Device  401  may also warn the user that the activity timer is about to expire at a predetermined amount of time before expiration. To warn the user that the activity timer is about to expire, device  401  may present a pop-up window, play an audible warning, display a light, cause a device to vibrate, etc., or otherwise notify the user of the pending expiration. Messages may also be arranged serially to provide an early warning, then final warning of an impending bandwidth management action. When multiple devices are synchronized and presenting the multimedia content item, messages may be sent to any or all of the participating devices to verify there is an active user. For example, with reference to  FIG. 1 , a video component may be presented by a wireless device  116  and by laptop computer  115 . A warning message may be presented at one or both of wireless device  116  and laptop computer  115 . Warning messages may also be sequentially sent to devices in a particular order. For example, messages may first be sent to handheld wireless device  116  before being presented as a pop up on television  112 . 
         [0044]    With reference again to  FIG. 4 , in block  410 , device  401  may identify expiration of the activity timer as an inactivity event and then communicate a reduction request  412  to computing device  106 . Request  412  may instruct computing device  106  to halt delivery of one or more transmission transporting data fragments for one or more of the components, or to send a lower bandwidth version. For example, request  412  may instruct computing device  106  to stop sending fragment data for the video component and the data component, but to continue sending fragment data for the audio component. In another example, request  412  may instruct computing device  106  to send a lower bandwidth version of some or all of the components. For example, computing device  106  may send a standard definition version of a video component instead of a high definition version or a 3D version. In another example, lower bandwidth versions may also include screen shots instead of video, a smaller window, etc. In another example, computing device  106  may only send fragments of the data component (e.g., closed captioning information) instead of audio and video components. As such, computing device  106  and device  401  may autonomously scale back the bandwidth used for a particular session while attempting to avoid an unsatisfactory user experience. 
         [0045]    In other example aspects, device  401  may identify an inactivity event based on user action suggesting lack of interest in a multimedia content item being presented. For example, device  401  may be presenting a multimedia content item in a first GUI. If a user causes a second GUI to obscure at least a predetermined amount of the first GUI, device  401  may identify this action as an inactivity event. Device  401  may also initiate activity timer upon detecting that the at least a predetermined amount of the first GUI has been obscured. If the timer expires, device  401  may identify an inactivity event. Subsequent to identifying an inactivity event, device  401  may communicate reduction request  412  to instruct computing device  106  to halt sending of data fragments of the video component, or to send a reduced bandwidth version. 
         [0046]    In further example aspects, device  401  may identify an inactivity event based on monitoring whether an external device (e.g., external display monitor) presenting a component has been turned off. If device  401  determines that the external device has been turned off, device  401  may identify this action as an inactivity event. Device  401  also may initiate activity timer upon detecting that the external device has been turned off. If the timer expires, device  401  may identify an inactivity event. Subsequent to identifying an inactivity event, device  401  may communicate reduction request  412  to instruct computing device  106  to halt sending of data fragments of the component being presented by the external device. 
         [0047]    Computing device  106  may also monitor network conditions between device  401  and computing device  106  to determine whether to stop sending components to device  401 , or whether to send reduced bandwidth versions of certain components. For example, computing device  106  may include a bandwidth utilization detector to monitor current bandwidth utilization relative to total available utilization. Computing device  106  may compare current bandwidth utilization to one or more predetermined thresholds. If current bandwidth utilization exceeds a particular predetermined threshold, computing device  106  may identify a component requiring the greatest amount of bandwidth for delivery, and may halting sending that component or may provide a lower bandwidth version of that component. Upon the current bandwidth utilization falling below the particular predetermined threshold, computing device  106  may resume sending the higher bandwidth version. 
         [0048]    Even though computing device  106  may halt sending one or more transmissions of data fragments for one or more components, computing device  106  may keep the session active with device  401 . In an example, computing device  106  may halt sending of a transmission of video data fragments via the session, but may maintain the session in an active state. For example, at active state may indicate that computing device  106  has reserved a predetermined amount of network bandwidth, even though computing device  106  is no longer communicating a transmission of data fragments for a particular component. Keeping the session active may permit faster resumption of sending data fragments to the device, as compared to having to re-establish the session. 
         [0049]    When resumption of a transmission is desired, device  401  may communicate a component resumption request  414  to computing device  106  identifying the corresponding component. For example, computing device  106  may have halted transmission of a transmission of data fragments for a video component, and device  401  may request that the transmission be restored. Device  401  may communicate the resumption request  414  in response to identifying an activity event. An activity event may be input provided by the user and/or may be detected by device  401 . In an example, device  401  may detect an activity event based on user presence, activity, a device being turned back on, etc. For example, device  401  may have instructed computing device  106  to halt sending of a component due to an external device being turned off. Device  401  may detect that the external device has been turned back on, and then may communicate the resumption request  414 . In another example, device  401  may detect user movement and/or presence using a motion detection sensor, an accelerometer, etc., and then communicate request  404 . In a further example, device  401  may determine that a GUI in which a video component is being presented is no longer obscured by a second GUI, and may then communicate request  404 . In response to receiving request  414 , computing device  106 , at block  416 , may resume sending a transmission of data fragments to the device  401  for the corresponding component. 
         [0050]    Upon resumption, computing device  106  may send data fragments of the component based on a current location in time within the multimedia content item. For example, computing device  106  may have halted sending of video data fragments, but continued to communicate audio data fragments. Computing device  106  may determine a current time stamp of the audio data fragments being sent and send the video data fragments having the current and subsequent time stamps. 
         [0051]    In another example, computing device  106  may resume sending data fragments for all of the components based on the time at which the activity timer expired. This may permit the user to resume viewing or listening to the multimedia content item from the time he or she may have stopped being able to do so. For example, a multimedia content item may be thirty minutes long and the activity timer expired thirteen minutes into the content. Computing device  106  may resume sending data fragments for all of the components at the thirteen minute mark. Computing device  106  may also resume sending data fragments a predetermined amount of time before the activity timer expired, such as, for example, at a last time the activity timer was reset. The user may also use device  401  to specify the time at which to resume sending data fragments. 
         [0052]    With reference again to  FIG. 4 , at some time the activity timer may expire at device  401  may communicate component halt request  420  to computing device  106 . Subsequent to activity timer expiring, device  401  may reset the activity timer to determine whether to terminate a session. If an activity event is identified, device  401  may reset the activity timer and optionally may communicate a resumption request  414 . If an activity event is not identified prior to the activity timer expiring, device  401  may then initiate termination of a session. As discussed above, an activity event may be input provided by the user and/or may be detected by device  401 . Device  401  may also present a warning, similar to the discussion provided above, that the session is about to be terminated at a predetermined amount of time prior to expiration of the timer. Subsequent to the timer expiring in block  422 , device  401  may communicate a session termination request  424  to computing device  106 . Computing device  106  may receive and process request  424 , and respond with a termination acknowledgement message  426  to indicate that the session has been terminated. Computing device  106  and device  401  may later re-establish a terminated session, but doing so may require a greater amount of time as compared to resuming sending of a transmission of data fragments on an active session. 
         [0053]      FIG. 6  illustrates a flow diagram of an example method of managing, e.g. controlling, bandwidth usage in accordance with example embodiments of the disclosure.  FIG. 6  may be implemented by a computer, such as, for example, device  401 , or other apparatus such as a network or user computing device, (e.g. computer, server, wired or wireless user device, etc.). Some steps of the example method may be performed by a network device, while others are performed by a local user device. The order of the steps shown in  FIG. 6  may also be rearranged, additional steps may be included, some steps may be removed, and some steps may be repeated one or more times. The method may be stored on at least one non-transitory computer readable medium as computer executable instructions that, when executed by at least processor, cause an apparatus to perform the method. The method may begin at block  602 . 
         [0054]    At block  602 , the method may include establishing at least one session for delivery of at least a first component and a second component of a multimedia content item. At block  604 , the method may include receiving, during the at least one session, a first transmission of data fragments of the first component and a second transmission of data fragments of the second component. The transmissions may be a stream, file based, or any other type of transmission. At block  606 , the method may include synchronizing the first transmission of data fragments and the second transmission of data fragments, and presenting the synchronized data fragments for rendering of the multimedia content item. At block  608 , the method may include identifying an inactivity event subsequent to the rendering. At block  610 , the method may include, subsequent to the identifying of the inactivity event, maintaining the at least one session in an active state and performing one of: requesting that delivery or providing a message that subsequently causes the first transmission of data fragments be stopped, or requesting delivery of a lower bandwidth version of the first component. The method may then end, or may return to any of the preceding blocks. 
         [0055]    The various features described above are merely non-limiting examples, and can be rearranged, combined, subdivided, omitted, and/or altered in any desired manner. For example, features of the servers can be subdivided among multiple processors and computing devices. 
         [0056]    Any of the above-mentioned functional components may be implemented with at least one processor and at least one memory. The functional components may include hardware that may execute software and/or be configured in hardware to perform specific functions. The software may be stored on a computer-readable medium in the form of computer-readable instructions. A computer may read those computer-readable instructions, and in response perform various steps as defined by those computer-readable instructions. Thus, any functions attributed to any of the components of  FIG. 1  as described herein may be implemented, for example, by reading and executing such computer-readable instructions for performing those functions, and/or by any hardware subsystem (e.g., a processor) from which the computer is composed. 
         [0057]    While embodiments have been described with respect to specific examples including presently preferred modes of carrying out the invention, those skilled in the art will appreciate that there are numerous variations and permutations of the above described systems and techniques. Thus, the spirit and scope of the invention should be construed broadly as set forth in the appended claims.
