Simulated television is the TV of an analog signal transmission or processing, and generation, transmission, the processing of its picture signal, which are arrived, to be received
The recovery of machine, what whole process was nearly all completed in the case where simulating constitution, it is characterized in sampling using time shaft, per frame in Vertical Square
To sampling, television image signal is transmitted in a manner of amplitude adjusted, while avoids sensitive frequency of the human eye to image repetition, by 1 frame
Image is divided into odd, even two field scan again.
DTV refers to from studio to transmitting, transmission, all links for receiving all be using digital television signal or
The signal propagation all to the system is all the digital stream being made up of 0,1 numeric string come the television genre propagated, its signal
Lose small, reception is good.The quality of programme content and quantity can be made to the greatest extent by DTV using advanced user administrative skill
Kind U.S. to the greatest extent simultaneously brings more programs selections and more preferable program quality effect for user, and digital television system can transmit a variety of
Business, such as high-definition television, standard definition television, interactive TV, BSV be liquid crystal-spliced and data service.With simulation
TV is compared, and DTV has the characteristics of picture quality is high, program capacity is big and sound accompaniment effect is good.
Numeral and simulated television help people are home-confined can just understand great undertakings, but simultaneously, people are watching electricity
Depending on that can be interfered when program, or some violation programs are received, influence normally to watch, or even bad shadow is produced to society
Ring.
The content of the invention
, should it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of analog- and digital- television monitoring equipment
Equipment can either realize the demodulation to broadcast television signal, and and can is enough to be compressed to video/audio, stores, and will can be regarded
Voice data carries out network transmission, while is provided with IO and turns network interface and can cross the mutual conversion realized between switching value and TCP.
The purpose of the present invention is achieved through the following technical solutions：A kind of analog- and digital- television monitoring equipment, it

Three described road analog television receivers and the video of CMMB receivers, audio output are connected with video server respectively, described
IO turn the control port that network interface outputs a control signal to three road analog television receivers and CMMB receivers；
Described TV distributor is by the video signal source mean allocation of reception vision signal consistent into multichannel, synchronous；
Described analog television receiver receives analog video signal, and signal is demodulated, and is reduced to video signal and low
Frequency audio signal；Described CMMB receivers receive mobile multimedia broadcast signal, and signal is demodulated, and are reduced to video
Picture signal and audio signal, and ensure the smoothness of signal；Described video server connects analog television receiver and CMMB
Receipts machine demodulate the video/audio come be compressed, store, coded treatment and network transmission；Described IO turns network interface realization
Mutual conversion between TCP and switching value.
Described casing uses 19 inch standard 2U cabinets.
Described analog television receiver uses the quick LT291HD TV boxs in day.
