Title:
VIDEO TRANSMISSION SYSTEM VIDEO TRANSMISSION UNIT AND METHODS OF ENCODING DECODING VIDEO DATA
Document Type and Number:
WIPO Patent Application WO2003007613
Kind Code:
A3
Abstract:
A video transmission system (400) includes a plurality of video transmitters (420, 430, 440), each video transmitter transmitting at least one respective video image. At least one vide receiver (410) receives video images from the video transmitters. The at least one video receiver includes a plurality of frame stores (412, 414, 416) for storing video images from the respective plurality of video transmitters. This provides advantages that: surveillance on band-limited multiplexed channels is much faster, without sacrificing the spatial image resolution of the object (s) of interest; images receovered have better perceptual quality: there is higher spatial resolution for object (s) of interest; there is quick first image display time, and subsequent video frames will be transmitted rapidly. A CCTV system can thus poll multiple video transmitters more quickly.
