A video playback control method and device

Abstract

The invention is suitable for the technical field of videos, and provides a video playing control method and device. The video playing control method includes the steps of receiving television signals sent by a server, wherein a standard definition video and a high definition video of a same television program are simultaneously transmitted in the television signals; receiving a program mapping table, sent by the server, of the television program, wherein the program mapping table comprises a first identifier for identifying the standard definition video of the television program and a second identifier for identifying the high definition video of the television program; when an audio-video terminal has the playing qualification for the high definition video of the television program, modifying the program mapping table to be characterized through the second identifier, and sending the television signals and the modified program mapping table to the audio-video terminal to enable the audio-video terminal to extract and play the high definition video of the television program. According to the video playing control method and device, the use rate of channel resources for playing the standard definition video and the high definition video and the playing control flexibility are greatly improved.
