背景技术Background technique
目前，电视广播节目中经常插播一些广告，从而使运营商通过广告进行营利。然而，用户只能被动接收电视广播节目中的广告，而无法自主选择是否需要观看。当前的方法中，只能屏蔽掉电视广播节目中的图像广告，而无法过滤掉音视频广告。在同一传输流中，由于电视广播节目中的节目与广告均为音视频类型，他们使用同一个PID（PackageIdentifier，包标识符），使机顶盒等节目接收设备无法区分视频与广告，从而无法过滤掉节目中的广告，降低了用户体验。At present, some advertisements are often inserted in TV broadcasting programs, so that operators can make profits through advertisements. However, users can only passively receive advertisements in TV broadcast programs, but cannot independently choose whether to watch them. In the current method, only image advertisements in TV broadcast programs can be blocked, but audio and video advertisements cannot be filtered out. In the same transmission stream, since the programs and advertisements in TV broadcast programs are both audio and video types, they use the same PID (PackageIdentifier, package identifier), so that program receiving devices such as set-top boxes cannot distinguish between video and advertisements, and thus cannot filter out The advertisements in the program reduce the user experience.
