METHOD AND APPARATUS OF SUPPORTING A VIDEO PROTOCOL IN A NETWORK ENVIRONMENT

摘要

A method and apparatus of supporting a video protocol in a network environment. Video processing and hardware requirements associated with a receiver are minimized by specifying a single video protocol for transmission of video data between transmitters and receivers on a network. The protocol specifies a color format that allows for high video quality and minimizes the complexity of the receiver. Transmitters convert video data into the designated protocol as needed. The designated protocol specifies a color format including a luminance value and two chrominance values. Quantized differential coding is applied to the luminance value and subsampling is performed on the chrominance values to reduce transmission bandwidth requirements. Upscaling of video data is performed at the receiver, whereas downscaling is performed at the transmitter. Various display sizes can thus be accommodated with efficient use of network bandwidth.
