Television system and video processing method

摘要

A video signal processing method applied for a TV system is disclosed. In this method, the received video signal is processed by a video decoding process, and then the decoded video signal is processed by a de-interlacing process. A still or corresponsively still image signal is generated and blended with the de-interlaced video signal to generate a blended signal which is displayed to make sure the OSD information can always be shown at the top layer of the screen of the LCD panel.

主权项

1. A TV system comprising
a first integrated circuit (IC) chip, comprising:
a first logic module, for executing a first video process on a received video signal; anda second logic module, for generating a still or a corresponsively still image signal;a first transmission interface, coupled to said first IC chip, for transmitting said video signal processed by said first logic module through a first transmission form;a second transmission interface, coupled to said first IC chip, for transmitting said still or corresponsively still image signal generated by said second logic module through a second transmission form; a second IC chip, coupled to said first transmission interface and said second transmission interface, said second IC chip comprising:
a third logic module, for executing a second video process on said processed video signal from said first transmission interface; anda fourth logic module, for blending said video signal processed by said third logic module with said still or corresponsively still image signal from said second transmission interface to generate a blended signal; anda display panel coupled to said fourth logic module, for displaying according to said blended signal.
