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: Protecting elementary stream media content is described. In one aspect, data segments within elementary stream media content are identified. Each data segment includes a single video or audio frame. Encryption boundaries for protecting the payload packets are selected to correspond to data segment boundaries. The elementary stream media content is then protected using the selected encryption boundaries.

摘要: A client device receives streaming content from a host device. The streaming content is placed in one or more buffers prior to processing. Monitoring as to the capacity and fullness of the buffers is performed at the client device and information is sent to the host device. The host device adjusts the rate or flow of the streaming content based on the information provided by the client device.

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: A transrate manager on a host computer determines if there is a limitation in network bandwidth and controls the bit-rate of streaming media content accordingly. The bit-rate is controlled by excluding types of video frames from the streaming media content and then reintroducing excluded types of video frames back into the streaming video content once the network has recovered.

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: Program code enabling the streaming of HD content in real-time to a game console is stored on a storage medium remote from the game console. The game console executes software that facilitates transfer of the program code from the remote storage medium to the game console. The program code ensures that sufficient bandwidth exists on a network between the game console and a HD tuner, and enables the streaming of HD content in real-time to the game console.

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.
