摘要： A video encoding system performs packetization of FGS/PFGS encoded video bitstreams by selecting encoded bitstream segments for packetization based on an estimated total contribution to distortion reduction associated with each encoded bitstream segment. The selected bitstream segments are then packetized according to a packet-independence packetization strategy that minimizes inter-packet dependency.

摘要： The techniques and mechanisms described herein are directed at transmitting elementary streams in a broadcast environment. The mechanisms provide a buffer controller and packet scheduler that allow a media format to be transmitted through the broadcasting environment in a manner resulting in a low channel switch delay. A buffer-fullness indicator allows the operation with various types of decoders. A lower bound and an upper bound are calculated for each frame within the elementary stream. The lower bound corresponds to an earliest time for sending the frame without causing an overflow condition within a decoder buffer. The upper bound corresponds to a latest time for sending the frame without causing an underflow condition within the decoder buffer. A send time is then scheduled based on the lower bound and the upper bound that determines when a packet associated with the frame is transmitted over a channel in a broadcast environment.

摘要： A video coding system and method utilizes a 3-D wavelet transform that is memory efficient and reduces boundary effect across frame boundaries. The transform employs a lifting-based scheme and buffers wavelet coefficients at intermediate lifting steps towards the end of one GOP (group of pictures) until intermediate coefficients from the beginning of the next GOP are available. The wavelet transform scheme does not physically break the video sequence into GOPs, but processes the sequence without intermission. In this manner, the system simulates an infinite wavelet transformation across frame boundaries and the boundary effect is significantly reduced or essentially eliminated. Moreover, the buffering is very small and the scheme can be used to implement other decomposition structures. The wavelet transform scheme provides superb video playback quality with little or no boundary effects.

摘要： A video encoding system uses both a central processing unit (CPU) and a graphics processing unit (GPU) to perform video encoding. The system implements a technique that enables the GPU to perform motion estimation for video encoding. The technique allows the GPU to perform a motion estimation process in parallel with the video encoding process performed by the CPU. The performance of video encoding using such a system is greatly accelerated as compared to encoding using just the CPU. Also, data related to motion estimation is arranged and provided to the GPU in a way that utilizes the capabilities of the GPU. Data about video frames may be collocated to enable multiple channels of the GPU to process tasks in parallel. The depth buffer of the GPU may be used to consolidate repeated calculations and searching tasks during the motion estimation process.

摘要： Systems and methods are described for using peer-to-peer collaboration to enhance streaming of multimedia content. A peer-paired pyramid streaming (P3S) architecture is introduced that is a hybrid of a client/server structure and a peer-to-peer structure. Clients are hierarchically organized and those that are in the same level are coupled to form peer-pairs. The peers in a peer-pair cooperate by utilizing a connection between them. Streaming is enhanced by allowing each peer to download different portions of a stream and sharing portions not in possession of the other. Error recovery is enhanced by allowing a peer to retrieve a dropped packet from its corresponding peer. A colored overlay is used with a P3S structure to improve streaming throughput.
