Audio comparison system based on contents

Abstract

The invention discloses an audio comparison system based on contents. Steps are comprised as follows, signal input, pre-processing, audio comparison and parameter output. The voice identification technology is referred, the audio content comparison algorithm technology based on samples is employed, same-source audios are compared, high feasibility is realized, moreover, high-quality signal acquisition on a broadcast link is made to be easier and simpler through application of the AoIP technology, more abundant feasible comparison characteristics can be directly provided for the comparison technology, the digital signal processing technology is further employed, comprehensive monitoring of broadcast signal quality is easily realized, broadcast safety can be guaranteed, and broadcast accidents can be prevented.

Description

technical field [0001] The invention relates to a broadcast service system, in particular to a content-based audio comparison system, and belongs to the field of broadcast correction. Background technique [0002] Broadcasting gradually became a reality due to the widespread use of radio and people's proficiency in the skills of high-power transmitters and high-sensitivity tube receivers. In 1919, the Soviet Union built a high-power transmitter, and in 1920 began experimental broadcasting in Moscow. On June 15, 1920, the Marconi Company held a "Radio-Telephone" concert starring Mrs. Melba in England, which could be clearly heard as far away as Paris, Italy, Norway, and even Greece. This is how the broadcasting career began. On November 2, 1920, in the United States, under the direction of Conrad, the Westinghouse radio station KDKA began broadcasting. The first broadcast was the Harding-Cox presidential election, which was a sensation at the time . On December 22, 1920, ...

Problems solved by technology

[0004] In the development of broadcasting, the safety of broadcasting has always been a key issue. The existing technology is to ensure the safety of broadcasting by manually comparing the sound broadcast by the terminal with the real-time sound on the spot, but manual comparison is prone to errors , and it is easy to cause broadcast accidents due to the negligence of operators
