Multi-version broadcasting method and system for video and audio programs

Abstract

The present invention provides a video and audio program multi-version playing method and system. The method comprises the following steps: a center end is configured to provide corresponding local materials for a plurality of play-cutting end; the center end needs the upper / lower play-cutting positions in the host video and audio program signal to add audio watermarking; the center end plays the host video and audio program and transmits the host video and audio program to a plurality of play-cutting ends; the play-cutting ends receive the host video and audio program signals and monitors and analyzes the audio watermarking; and when the play-cutting type in the audio watermarking is identified as the upper play-cutting identification, the outputting the host video and audio program signals are switched to the local material program signals, and when the play-cutting type in the audio watermarking is identified as the lower play-cutting identification, the output local material program signals are switched to the host video and audio program signals. The video and audio program multi-version playing method and system realize the automatic play cutting, are simple in control process and effective, and can mitigate the operators' mental stress.

Description

technical field [0001] The invention relates to the technical field of broadcasting video and audio programs, in particular to a multi-version broadcasting method and system for video and audio programs. Background technique [0002] In the broadcasting of video and audio programs, for example, in the most common TV broadcasting, the video and audio programs are sent from the TV station, and generally need to be relayed by some relay stations to reach the end user. For example, satellite TV programs are transmitted to various rebroadcasting stations through satellites, and then the rebroadcasting stations are delivered to end users through cable networks and other methods. In some broadcasts, due to some special needs, it is necessary to replace part of the original audio and video programs with other broadcast programs. For example, in some applications such as regional advertisements, the original advertisements are replaced with localized advertisements. This broadcast ...

Problems solved by technology

However, for this kind of interception, some use storage media such as optical discs and flash memory to broadcast all programs for different regions as a whole, and the workflow is relatively cumbersome. It reduces the workload of changing programs and greatly increases the probability of errors
