Abstract: 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.

Abstract: Rate control algorithms are adapted to cover multiple encoding standards are described. A rate controller includes an input adaptation interface, a core rate controller, and an output adaptation interface. The input adaptation interface converts rate control input parameters of a target encoding standard to corresponding native control input parameters of the rate controller. The core rate controller is coupled to the output of the input adaptation interface generating output parameters conforming to its native encoding standard. The output adaptation interface is coupled to the output of the core rate controller converting the generated output parameters to equivalent rate control output parameters conforming to the target encoding standard.

Abstract: 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 (302) and a second module (306). The system further includes a memory module (304). The first module (302) decodes the input video bit stream for generating pixel data and macroblock specifications. The second module (306) encodes the pixel data and the macroblock specifications for constructing the output video bit stream. The memory module (304) 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.
