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： It is known to represent a square block of an image which has a maximum horizontal or vertical extension N as N vectors each representing one column or row, and encode it using an N×N discrete cosine transform matrix. We introduce a technique which transforms an input vector, or array, representing a portion of an arbitrarily-shaped object block in which the maximum horizontal or vertical extension is at most N, by adding to it additional padding elements, to produce a vector or array which can be encoded using an N×N discrete cosine transform. The padding maximises the number of transformed elements which are zero. We propose encoding arbitrarily-shaped objects based on this padding technique.

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： Efficient integrated digital video transcoding is described. In one aspect, an integrated transcoder receives an encoded bitstream. The integrated transcoder transcodes the encoded bitstream by partially decoding the encoded bitstream based on a first transform associated with a first media data format. The decoding operations generate an intermediate data stream. The integrated transcoder then encodes the intermediate data stream using a second transform associated with a second media data format. The first and second transforms are not the same.
