Abstract

The invention discloses a method and a device for performing digitized reconstruction on an analog television transmitter. An analog signal modulator which is equipped on the original analog television transmitter and a radio frequency signal distributor of a power amplifier unit of the original analog television transmitter are removed; and a digital television excitation amplification device isconnected between an input video / audio TS data stream and a part of the power amplifier unit of the original analog television transmitter after the radio frequency signal distributor is removed, andis cooperated with the part of the power amplifier unit of the original analog television transmitter after the radio frequency signal distributor is removed, so that the aim that the analog television transmitter is subjected to digitized reconstruction is fulfilled. By the method and the device, useful devices of the original analog television transmitter can be utilized completely, so that thedigitized process of each television station from analog television terrestrial broadcasting to digital television terrestrial broadcasting is accelerated, and expenses required at the early stage ofthe digitized process are reduced.

Description

technical field [0001] The invention relates to the technical field of television transmitters, in particular to a method for transforming an analog television transmitter into a digital television transmitter and related devices. Background technique [0002] The development of digital technology has promoted the advancement of digital TV technology, making it one of the fastest growing technologies in the past 20 years. my country's digital TV industry has developed rapidly and has entered the era of digital TV replacing analog TV. Hundreds of cities have launched digital TV terrestrial broadcasting. The adoption of digital technology can not only enable various TV devices to obtain higher performance than the original analog devices, but also realize new functions that cannot be realized by analog technology. [0003] However, the replacement of analog TV terrestrial broadcasting by digital TV terrestrial broadcasting has its own process and development. In a certain sta...
