Description

technical field

[0001] The present invention relates to television sets, especially an invention relating to image signal processing devices of digital television sets. Background technique

[0002] For digital TV in general, due to the recent development of TV technology, the transmission method of broadcast signals has also developed. As a result, users' interest in digital televisions to which the data transfer method is applied has also increased.

[0003] Moreover, as far as the country is concerned, the Mugunghwa satellite was launched in August 1995, and the test broadcast of digital TV began in July 1996. Unlike existing broadcasts, Mugunghwa Satellite Broadcasting uses SDTV-level digital broadcasting, which is hardly different from terrestrial digital broadcasting that is expected in the future.

[0004] On such a digital TV set, a user can use a personal video recorder (Personal Video Recorder; PVR) to store images in real time during watching TV, and can replay ...
