Description

  The present invention relates to a channel switching module. In particular, when an erroneous signal monitored by a media player is received by a server host, the program is switched or sent to a channel switching module for switching to a media channel. The present invention relates to a channel switching module that prevents a media signal from being reproduced and further transmits advertisements and television programs without interruption.

  Since the advent of TV, it gradually replaced the current LCD TV and plasma TV from the initial black and white TV and color TV. The television display effect has already entered an era of high image quality, high resolution, good contrast, and good color. In addition, the number of TV channels has also shifted from the initial number of channels to the number of channels close to one hundred, and the TV signal transmission system has also changed with the times, and has rapidly evolved from analog to digital. is doing.

  Regardless of the type of signal transmission of the current TV monitor, whether it is an analog signal or a digital signal, all signals are played back by a specific playback method. For example, a television display connects a signal code on a video transceiver, and video is transmitted through this video transceiver. , Receive and play sound source. In particular, a personal computer display must be connected to a PC host, and data processed by the PC host is displayed and reproduced on the display.
