Abstract

The invention discloses an analog and digital television monitoring device, which comprises a casing (1) and an internal circuit. The front panel of the casing (1) is provided with a power switch (2) and an indicator light (3). The rear panel of the shell is provided with a power interface (4), one or more network ports (5), a VGA video signal output interface (6), a TV signal input interface (7) and an internal TV signal output interface (8). The circuit includes a power module, a TV distributor, a three-way analog TV receiver, a CMMB receiver, a video server and an IO transfer network port. The invention provides an analog and digital TV monitoring device, which can not only realize the demodulation of broadcast TV signals, but also compress and store the video and audio data, and can transmit the video and audio data through the network, and is equipped with an IO The switch port can realize the mutual conversion between switching value and TCP.

Description

technical field [0001] The invention relates to a TV monitoring device, in particular to an analog and digital TV monitoring device. Background technique [0002] Analog TV is a TV that transmits or processes analog signals. The entire process of image signal generation, transmission, processing, and receiver restoration is almost completed under analog conditions. It is characterized by sampling on the time axis. Sampling in the direction, transmitting the TV image signal by amplitude adjustment, while avoiding the sensitive frequency of human eyes to image reproduction, and dividing one frame of image into two fields of odd and even scanning. [0003] Digital TV refers to the type of TV in which digital TV signals are used in all links from the studio to transmission, transmission, and reception, or all signal transmission to the system is transmitted through digital streams composed of 0 and 1 digital strings. The signal loss is small and the reception effect is good. D...
