Method and system for chroma partitioning and rate adaptation for uncompressed video transmission in wireless networks

摘要

A method and system for transmission of video information is provided. A transmitting wireless station performs chroma partitioning of pixels in a video frame into different partitions. The chroma partitioning includes separating luminance (Y) information from chrominance information (CB and CR) of each pixel in a set of spatially correlated pixels. The luminance (Y) information are placed into different partitions. The different partitions into different packets and transmitted over a wireless communication medium to a receiving wireless station. The video information is selectively adapted to a lower data transmission rate with reduced quality degradation by dropping less important partitions.

1. A method of wireless transmission of video information, comprising:
in a transmitting wireless station, chroma partitioning pixels in a video frame into different partitions, wherein chroma partitioning includes separating luminance (Y) information from chrominance (CB and CR) information of each pixel in a set of spatially correlated pixels, and placing the Y information and the CB and CR information into different partitions in different orders, wherein one or more of the Y information, and the CB and CR information switches on octet boundaries; placing the different partitions into packets; and transmitting each packet over a wireless communication medium to a receiving wireless station.
