    摘要: While streaming media content, trick mode operation is optimized to a level that can be readily accommodated by available resources of a media delivery system. In one possible strategy, a trick mode optimization module may decrease the bit rate of the media content stream by progressively dropping delta frames and then a fraction of the remaining key frames as needed. According to another possible strategy, the trick mode optimization module may decrease the bit rate of the media content by progressively dropping sequences of frames between successive key frames. In addition, the trick mode optimization module may combine strategies and drop sequences between key frames, as well as dropping delta frames from the remaining sequences.

    摘要: Real-time streaming of media content from a server to a device and reduction of startup latencies during distribution are described. In one configuration, once a latency inducing event is initiated (i.e. a channel change, a stopping and starting of the streaming of live media content, or transrating to different streaming rates) a pre-roll process includes decreasing the frame rate of the media content being streamed to the monitor from an initial rate to a reduced rate. Simultaneously, a jitter buffer is flushed and rebuilt with media content samples arriving at a decoder at the initial rate, and being used for playback at the reduced rate.

    摘要: The present disclosure relates to playback of video/audio streaming media data with seamless advertisement insertion. A content player monitors playback of the media stream and determines a location to insert an advertisement. The content player pauses downloads of the media stream and begins downloading the advertisement while the media stream continues to be rendered. The advertisement is, consequently, loaded prior to a start time and allows for an instantaneous rendering at an advertisement insertion point in the media stream.

    摘要: Partial content syncing in a network media receiver is disclosed. One embodiment comprises identifying available cache space on the media receiver, detecting a media data file to be downloaded from a media server, and pre-buffering a portion of the media data on the media receiver prior to selection of the media data file for playback. In this manner, substantially glitch-free playback of a media data file may be started with little delay and with relatively little local storage.

    摘要: Various embodiments permit access to a software component's functionality to be limited. In at least some embodiments, access to some or all of a component's functionality can be limited through the use of a validation identifier that is used as a means to validate another entity wishing to access the limited functionality or bind that entity to the particular component.

    摘要: A system receives multiple data samples and determines time stamp values associated with each of the multiple data samples. The system identifies an earliest time stamp value and uses that time stamp value as an initial system clock value. The system may also subtract a delay factor from the earliest time stamp value to account for delay in decoding the multiple data samples. The earliest time stamp value is also communicated to an audio decoder and a video decoder. The audio and video decoders provide clock data back to a component that maintains the system clock value. If the difference between the clock data received from the decoders and the system clock value exceeds a threshold value, the system clock value is recalculated.
