Method and device for audio data transcoding and transcoding server

Abstract

The invention discloses a method for audio data transcoding. The method comprises the steps that EPG (electronic program guide) information of audio data stream to be collected is obtained; an audio signal is collected from an equipment interface corresponding to an equipment channel according to the equipment channel arranged in a preset configuration file; the audio signal is encoded into audio data with a preset format according to a coding format and coding parameters arranged in the preset configuration file; and the audio data is stored as an audio program file according to a transcoding audio data file storage position, a naming rule and the EPG information arranged in the preset configuration file. According to the technical scheme, the collected audio data can be independently stored in a server and used for audio on demand in the form of program according to the preset configuration file and the EPG information, and the collection and transcoding efficiency of the audio data can be improved. The invention also discloses a device and a transcoding server for implementing the method.

Description

technical field [0001] The present invention relates to the field of audio technology, in particular to an audio data transcoding method, device and transcoding server. Background technique [0002] With the development of existing audio and video technologies, the traditional broadcast-based audio system has begun to develop into online live broadcast or on-demand services. The audio collection and processing capabilities of the existing system can no longer meet the business development of "Internet Radio", the access and collection of digital signals, and the system processing capabilities cannot meet the business needs of recording, encoding and live broadcasting of more channel signals. [0003] The virtual live broadcast of traditional radio program production adopts the service standard of Windows Media Services (Windows Media Services). Editors arrange the edited audio files in wma format by manually configuring the playlist, and execute the scheduled tasks of the Wi...

AI Technical Summary

Problems solved by technology

The audio collection and processing capabilities of the existing system can no longer meet the business development of "Internet Radio" and the access and collection of digital signals, and its system processing capabilities cannot meet the business needs of recording, encoding and live broadcasting of more channel signals.

[0003] The virtual live broadcast of traditional radio program production adopts the service standard of Windows Media Services (Windows Media Services). Editors arrange the edited audio files in wma format by manually configuring the playlist, and execute the scheduled tasks of the Windows operating system every day To switch the playlist, this working mode is very inflexible, and it is not convenient and intuitive to adjust the edited playlist, resulting in a heavy workload of system operation and a high failure rate of the system, which is not suitable for the requirements of the current network business development

[0004] The on-demand service system of traditional radio programs is generally based on the Real system, which controls and collects multi-channel audio signals in a time-segmented manner and records them as rm (real media, a format of network streaming media) format files, and then transmits them to Real Media in a centralized manner. The Service (RM format media service) server provides external on-demand services. The collection process of this system often hangs up abnormally, resulting in collection omissions and failures. It is necessary to manually retrieve the required data from other media platforms, which results in low efficiency and collection failures. High efficiency, poor timeliness, poor manageability, and the need for a lot of manual work
