Apparatus and method for signal processing of a format conversion and combination of the video signals

摘要

A device for converting and mixing a plurality of video data, wherein the video data have a plurality of sampling formats, wherein the sampling formats at least a format with a high chrominance sampling rate and a format with a low chrominance sampling rate, and the apparatus comprises:a first data reception end for receiving first video data in the format with a low chrominance sampling rate;a second data reception end for receiving of second video data in the format with a high chrominance sampling rate;a format conversion module which, together with the first data reception end of which is electrically connected to the increase of the first video data, in order to the first video data in the format with a low chrominance sampling rate in the first video data in the format with a high chrominance converting sampling rate; anda data mixer which, with the format conversion module and the second data reception end of which is electrically connected to the mixing of the first video data in the format with a high chrominance sampling rate with the second video data in the format with a high chrominance sampling rate, mixed video data in the format with a high chrominance sampling rate to produce.
