摘要:
A method for presenting audio-visual content for a display includes defining a window associated with a program having associated audio signals on the display. An audio position is defined for the audio signals based upon a position of the window on the display, and a position of at least two speakers associated with the display. The audio signals are modified based upon the audio position in such a manner that the audio signals appear to originate from the window.

Systems and methods for identifying original streams of media content are disclosed. An exemplary method involves identifying at least one media content identifier in a media content directory. The media content identifier identifies media content. A plurality of stream access identifiers may be associated with the media content identifier. The method also involves identifying at least one stream access identifier of the plurality of stream access identifiers that includes access information for accessing an original stream of data from a media file comprising the media content. The method also involves providing identifier information about the at least one stream access identifier to a client in response to a client request.

A system for enabling an IPv4 (Internet Protocol version 4) application to communicate across a computer network with an IPv6 (Internet Protocol version 6) system. The system includes a computing device and executable instructions. Executable instructions are configured to make a function call to an IPv4 socket Application Programming Interface (API). The instructions translate the function call to a translated function call wherein the translated function call uses raw sockets. Another function call is made to the IPv4 socket API for the translated function call that uses raw sockets. A packet is passed to an IPv4 stack.

The embodiments of the present invention provide for methods, devices, and systems adapted to reduce initial buffering delay encountered at the client side by selectively dropping content elements of a source content within a drop interval prior to transmission to a client or receiver. The drop interval associated with the initial buffering delay value at the client.

A system and method have been provided for achieving simultaneous media playout in a network including a server and a plurality of clients. The method comprises: from a server, supplying a media stream to clients at a first bitrate (R1); determining the network delivery requirement; and, in response to the network delivery requirements, modifying the supply of the media stream. Determining the network delivery requirements includes determining either the buffering capacities of the clients, or the media streaming disruptions. To determine the buffering capacities of the dents, a first minimum client buffering capacity (C1) is determined by polling the clients for their respective buffering capacities, and selecting the first minimum buffering capacity (C1) to be equal to the client with the smallest buffering capacity.
摘要:
In a computer network, the bandwidth of the communication channel connecting nodes of the network is limited. A cost function is used to allocate the bandwidth of the channel among the data for a plurality of elements in a multimedia session. The cost function relates the distortion produced by a change in encoding rate for one or more media with a delay in transferring data related to another medium at a particular rate. A fairness criterion, expressing the relative weighting of the distorted and delayed elements for specific applications, can be included in the cost function. The cost function can be used to allocate the bandwidth between media from both push and pull sources.

A battery powered device including power management includes a display, a processor, a video decoder, a networking circuit, and a power allocation process. The power allocation process modifies the power used to process a video by jointly selecting a lower power usage based upon selectively dropping frames to be decoded by the video decoder, and selectively decreasing the illumination of a backlight of the display.

A method for tracking a reference picture on an electronic device is described. The method includes receiving a bitstream. The method also includes decoding a portion of the bitstream to produce a decoded reference picture. The method further includes tracking the decoded reference picture in a decoded picture buffer (DPB) with reduced overhead referencing based on a designated picture. The method additionally includes decoding a picture based on the decoded reference picture.
摘要:
A method for reducing signal overhead on an electronic device is described. The method includes obtaining a picture. The method also includes encoding the picture. The method further includes indicating a reference picture set (RPS) corresponding to the picture based on an initialized index value. The method additionally includes sending a bitstream.
