DIGITAL VIDEO TRANSMISSION DEVICE AND METHOD, DIGITAL VIDEO RECEPTION DEVICE AND METHOD, AND DIGITAL VIDEO TRANSMISSION AND RECEPTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a digital video transmission and reception system and method.

SOLUTION: A digital video transmission and reception system may includes: a video transmission device deciding a down-sampling rate depending on a bandwidth of a transmission network, down-sampling an ultra-high image quality digital video at the decided down-sampling rate, and encoding and multiplexing the down-sampled digital video to transmit the encoded and multiplexed digital video via a transmission network; a video reception device receiving the digital video transmitted from such a video transmission device and demultiplexing and decoding the received digital video, receiving information on the down-sampling rate from the video transmission device, and interpolating the decoded digital video based on the received information to restore the ultra-high image quality digital video. Accordingly, the ultra-high image quality digital video can be transmitted efficiently while minimizing deterioration in image quality.
