Abstract

This application relates to a channel switching method for mobile communication multimedia broadcasting and terrestrial digital television broadcasting. The method includes: inserting multiple program stream time tags into the target digital television broadcasting program stream to obtain two identical target program streams; inputting the target program streams to a target broadcasting channel and a mobile internet channel respectively, and performing program stream time tag detection to obtain first and second program stream time tag detection results; and based on the first and second program stream time tag detection results, performing buffer control on the target digital television broadcasting program streams to achieve real-time seamless switching of the target digital television broadcasting program between the mobile network digital television broadcasting platform and the terrestrial digital television broadcasting system. This solves the problems of incompatibility and lack of seamless integration between traditional broadcast television services and online audiovisual services, resulting in poor user experience.
