VIDEO ENCODING TRANSMISSION DEVICE AND VIDEO ENCODING AMOUNT CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To conduct efficient video transmission while increasing the viewing property of important regions on a wide-angle video without applying encoding transmission to the entire wide-angle video in a video encoding transmission device encoding and transmitting the video obtained by photographing with high resolution the wide-angle region.

SOLUTION: The video encoding transmission device comprises: a video segmentation section 103 segmenting a first region and a plurality of second regions from the wide-angle video; a main region processing section 104 extracting a non-important region from the first region; a main region encoding section 105 conducting encoding processing for the first region; an auxiliary region processing section 107 extracting the important regions from the second regions; an auxiliary region encoding section 108 conducting encoding processing for the important regions; and an encoding amount control section 106 deciding the important region to be superimposed on the non-important region and assigning encoding amounts to the first region and the important region. The video formed by encoding the important region on the auxiliary region is superimposed on the non-important region on a main encoded region for transmission.
