Title:
DEVICE FOR TRANSMITTING AND RECEIVING VIDEO IMAGE SIGNAL
Document Type and Number:
Japanese Patent JP3388859
Kind Code:
B2
Abstract:
PURPOSE: To provide a device and a method for selecting and sending an encoded block of video information at various channel rates.
CONSTITUTION: This device selects and sends an encoded block of this signal at various channel rates based on the corresponding part position of a video image that is shown by the encoded block. Each encoded block is designated to an image type which decides its sending channel rate. The image type is associated with the space position of a video image as the encoded block in a 1st area of the video image is a 1st image type and that the encoded block in a 2nd area is a 2nd image type. Generally, a data block that shows the central part of the video image is sent in a channel rate where sensitivity to noise and other deterioration is low, and the central part is receivable in a broadcast edge area.
