Abstract

The invention discloses a voice data coded format conversion method. The method includes the steps that when the conversion instruction of converting voice data in a first coded format into voice data in a second coded format is detected and received, the voice data in the first coded format are decoded to acquire corresponding original voice sampled data in a PCM format; the acquired original voice sampled data are coded according to the second coded format to acquire the voice data in the second coded format. The invention further discloses a voice data coded format conversion device. By means of the voice data coded format conversion method and device, the technical problem that the voice data in the PCM format need to be sampled again is effectively solved, the voice data coded format conversion workload is reduced, the voice data coded format conversion period is shortened, and the voice data coded format conversion efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of audio data processing of digital broadcast television signals in multicast technology, in particular to a method and device for audio data coding format conversion. Background technique [0002] In recent years, due to the rapid development of computer technology and network technology, the functional applications of TVs have become more and more perfect. Now TV users can not only watch DTV (digital television, digital TV) signal programs, ATV (Analog Television, analog TV) signal programs, but also receive FM (frequency modulation, FM) digital broadcast TV signals. [0003] At present, due to the development of digital technology, there are as many as dozens of types of audio data encoding formats, and audio data is encoded and stored in different encoding formats. In the prior art, there is no technical solution that can directly convert audio data in one encoding format into audio data in another enco...
