Abstract

The invention discloses a large-screen management subsystem and a large-screen synchronous playing system and method.The large-screen synchronous playing system comprises the large-screen management subsystem, a code coding and transcoding subsystem, an information source, large-screen equipment and a mobile playing terminal.The code coding and transcoding subsystem creates one or more code coding and transcoding tasks for the content of each playing list, and the code coding and transcoding subsystem creates one or more code coding and transcoding tasks; the quantity of the tasks is the same as the output quantity required by the playlist item; the file packaging format, the audio and video coding format, the network protocol format and the network output address output by each coding and transcoding task all come from the requirements of the broadcast list item.

Description

technical field [0001] The invention belongs to the technical field of audio and video processing, and in particular relates to a large-screen management subsystem, a large-screen synchronous playback system and a method. Background technique [0002] Large screens, especially outdoor large screens, are very conducive to the shaping and dissemination of brand image due to the characteristics of eye-catching screen, strong visual impact, wide viewing angle range, ultra-clear picture and dazzling colors, coupled with unique space advantages. Whether it is urban culture, live broadcast of major events, public welfare or commercial advertisements, the use of outdoor large screens can achieve good publicity effects. [0003] Outdoor large screens are usually located near commercial centers or residential areas. In order to avoid disturbing residents, there are special requirements for playback volume, either very low volume or silent playback. During video playback, especially li...
