Abstract

The invention which is suitable for the network TV and the digital TV system discloses a switch method used in the live broadcasting and replaying of the digital TV and a video server, and comprises the following steps: preserving the TV program information into a series of content fragment data, and generating the auxiliary data which is corresponding to the content fragment data; receiving the command with the live broadcasting and replaying of the timing information; looking for the corresponding content fragment data and playing position according to the time information in the live broadcasting and replaying commands and the auxiliary data which is corresponding to the content fragment data, and starting to play the content fragment data from the position. The invention generates a series of content fragment data in the disk, and generates the auxiliary data which is corresponding to the content fragment data, and the video server finds out the content fragment data to be played according to the request of users and the auxiliary data, and plays the content fragment data in the manner of pre-reading and pre-handoff; then, a seamless handoff effect of the switch between the playing and the replaying of the digital TV can be achieved.

Description

technical field [0001] The invention belongs to the field of network television and digital television systems, and in particular relates to a digital television live broadcast and playback switching method and a video server.
