The invention discloses an audio volume measuring system and method of digital broadcasting television. The audio volume measuring system of digital broadcasting television includes a business logic management module, an audio storage module, an audio volume analysis module, and an audio volume calculating module, wherein the audio storage module, the audio volume analysis module, and the audio volume calculating module are mutually independent; the business logic management module is used for managing and scheduling other modules; the audio storage module is used for storing the audio data inan audio data memory block; the audio volume calculating module is used for receiving a volume calculating command issued from the business logic management module, acquiring the corresponding audiodata from the audio data memory block and performing volume calculation, and storing the volume data of the audio data in the volume data memory block; and the audio volume analysis module is used forreceiving a volume analysis command issued from the business logic management module, acquiring the volume data of the corresponding audio data from the volume data memory block, and analyzing the volume situation of the corresponding audio data. The audio volume measuring system of digital broadcasting television can be applied to unified analysis of the audio volume situation of different channel programs.
Description
technical field [0001] The present invention relates to the technical field of audio loudness measurement, and more particularly, to an audio loudness measurement system for digital broadcast television and an audio loudness measurement method for digital broadcast television. Background technique [0002] When viewers watch radio and television programs, due to the large difference in the audio loudness of the programs of each channel, especially the audio loudness of advertisements on some channels obviously exceeds the audio loudness of regular programs, which seriously affects the audience's viewing and listening experience. In order to standardize the audio loudness and measurement methods of radio and television programs, the State Administration of Radio, Film and Television has issued "Program Loudness and True Peak Audio Level Measurement Algorithm" (GY / T262-2012), "Technical Requirements for Loudness and True Peak Indicating Instruments" (GY / T263 -2012), "Technical...
