Abstract

The invention relates to video / audio cut-off control device for digital receiver to shield unneeded program. Wherein, different with cut-off audio output, cutting off video can also output subtitle or sub-image information opposite to audio information. Wherein, the device comprises: a signal processor to demodulate and output information input with video information, and a control device to decide whether to cut off signal and control other video information if cut off.

Description

【Technical field】 [0001] The present invention relates to a video / audio cutting control device and method of a digital program receiver. More specifically, it cuts off undesired images from video / audio information displayed in digital TV programs or video information recording media. 【Background technique】 [0002] As we all know, digital TV receives digital program signals and displays and outputs video / audio information. This digital program can be divided into digital satellite programs, digital optical cable programs, or digital terrestrial wave programs. Set-top boxes (Set Top Box), restore the digital program signal of the MPEG transport stream (Transport Stream) to the original video / audio signal, and then send it to the digital TV, so that the user can watch the program content of the channel he wants to watch. [0003] In addition, this kind of digital television can receive and display video / audio information recorded in the same video information recording medium ...
