A system and method transcodes an input video bit stream having a first encoding profile into an output video bit stream having a second encoding profile. The system includes a first module () and a second module (). The system further includes a memory module (). The first module () decodes the input video bit stream for generating pixel data and macroblock specifications. The second module () encodes the pixel data and the macroblock specifications for constructing the output video bit stream. The memory module () includes a first buffer module and a second buffer module. The first buffer module stores the pixel data and the second buffer module stores the macroblock specifications.

System and method for transcoding data from one video standard to another video standard

An embodiment relates to a decoder for decoding CABAC encoded video data in real time for HDTV applications. The decoder comprises a binary arithmetic decoder block for converting an input bit stream into a bin string, a context memory for storing a plurality of context values, and a plurality of finite state machines. Each of the finite state machines is adapted for decoding a particular one of the H.264 syntax elements by providing the binary arithmetic decoder block with an index of the relevant context value within the context memory and by converting the resulting bin stream into a value of the current syntax element. In this manner, a performance of one bin per cycle may be achieved.

System for entropy decoding of H.264 video for real time HDTV applications

A system and method transcodes an input video bit stream having a first encoding profile into an output video bit stream having a second encoding profile. The system includes a first module and a second module. The system further includes a memory module. The first module decodes the input video bit stream for generating pixel data and macroblock specifications. The second module encodes the pixel data and the macroblock specifications for constructing the output video bit stream. The memory module includes a first buffer module and a second buffer module. The first buffer module stores the pixel data and the second buffer module stores the macroblock specifications.

Systems and methods are for implementing a NSV2SV converter that converts a non-scalable video signal to a scalable video signal. In an implementation, a non-scalable video signal encoded in H.264/AVC standard is decoded and segmented into spatial data and motion data. The spatial data is resized into a desired resolution by down-sampling the spatial data. The motion data is also resized in every layer, except in the top layer, of a scalable video coding (SVC) encoder by using an appropriate measure. Further, the motion data is refined based on the resized spatial data in every layer of the SVC encoder. The refined motion data and the down-sampled spatial data are then transformed and entropy encoded in the SVC standard in every layer. The SVC encoded output from every layer is multiplexed to produce a scalable video signal.
