VIDEO IMAGE FORMAT CONVERTING APPARATUS AND DIGITAL BROADCASTING RECEIVING APPARATUS |
摘要 |
PROBLEM TO BE SOLVED: To provide an inexpensive video format converting apparatus and a digital broadcasting receiving apparatus using the same in which large circuits such as a filter circuit, a memory and the like are reduced in the number of circuits. SOLUTION: Based upon a terminal specification of a main video output and combination of video sources in the case of not performing a video format conversion, the case of outputting after down converting and the case of outputting after up converting, operations of a video expanding/reducing means 4000 and a first horizontal expanding/reducing circuit 70 are selectively used so that one horizontal expanding/reducing circuit performs horizontal expanding/reducing processings of both the main video output and a sub video output.
