US 9,071,848 B2 · Sub-band video coding architecture for packet based transmission

Abstract

Sub-band video coding architecture for packet based transmission. Video processing includes converting of a frame or picture of a video signal into a number of respective sub-bands or sub-frames (e.g., such that each respective one is a respective subsampled version of an original frame or picture) and subsequent assembly thereof into a reconstructed frame or picture. The reconstructed frame or picture then undergoes video encoding to generate an output bitstream that may subsequently undergo appropriate processing (e.g., packetization, continuous time signal generation, etc.) to generate a signal for transmission via one or more communication the links. Characteristics associated with each respective sub-band or sub-frame may be similar (e.g., similar characteristics) or different (e.g., two or more sub-bands or sub-frames have different characteristics, such as different respective number of pixels, aspect ratios, etc.). Respective sub-frames may undergo video encoding and transmission.

Dependent claims

A communication device comprising:

a communication interface;
and
a processing circuit, the processing circuit and the communication interface configured to:
sub-sample a frame to generate a plurality of sub-frames, wherein each of the plurality of sub-frames is a respective sub-sampled version of a full version of the frame, wherein a first sub-frame of the plurality of sub-frames is a first sub-sampled version of the full version of the frame based on a first pixel marker, and a second sub-frame of the plurality of sub-frames is a second sub-sampled version of the full version of the frame based on a second pixel marker that is offset from the first pixel marker;
assemble the plurality of sub-frames to generate a reconstructed frame having pixels differentially ordered than the frame, wherein the reconstructed frame includes the first sub-frame and the second sub-frame adjacently arranged;
and
encode the reconstructed frame to generate at least a portion of an output bit stream;
and
transmit the output bit stream to another communication device.
