摘要： There are provided apparatus and methods for parallelizing an encoding process across multiple processors. An apparatus includes a computing resource balancer and a splitter. The computing resource balancer is for assigning encoder instances to respective ones of the multiple processors based on at least one of thread affinity and process affinity. The splitter is for temporally dividing an incoming video sequence into discrete GOPs such that each of the encoder instances is capable of encoding the incoming video sequence in parallel so that each of the discrete GOPs is encoded on a respective one of the multiple processors.

摘要： A device incorporates a software-based H.264 video encoder for providing compressed, or encoded, video data. The H.264 encoder incorporates a timer algorithm such that the time available to the H.264 encoder within the macroblock mode decision and motion estimation framework is constrained, or restricted. The particular amount of time available to the H.264 encoder then determines a subset of available encoding modes that the H.264 encoder can use to encode a macroblock.

摘要： There are provided methods and apparatus for audio and video synchronization timestamp rollover correction. A synchronization apparatus includes a synchronizer for providing synchronization information for synchronizing a video stream with an audio stream during any point in a broadcast thereof irrespective of whether the video stream and the audio stream have different rollover points for their respective timestamps. The synchronization information is encoded for an out of band transmission with respect to the broadcast of the audio and video streams.

摘要： A Video Server (VS 100) encodes a video stream according to the values of parameters and transmits the video stream over a Network to a Video Client (VC 200) that decodes the received video stream for presentation to a user. As the video stream is being received, (VC 200 continually gathers data regarding at least the condition of Network sends this data to (VS 100). (VS 100) modifies the values of the parameters based on the data received from (VC 200), which in turn modifies the encoding of the video stream.
