Abstract

The embodiment of the invention provides a playing method for a live program. The playing method comprises the following steps: acquiring an index document of the live program from a live program server; parsing the index document; acquiring EIT (Event Information Table) information from the index document; acquiring a program zone of the live program from the live program server according to the index document; conducting playing control on the program zone according to the EIT information. By expanding the EIT information to the index document, the playing method can accurately describe time information of the live program, and can conduct the control of the zone grade on the playing of the live program according to control information in the EIT.

Description

technical field [0001] The invention relates to the field of Internet video, in particular to a method and terminal for playing live programs, and a method and device for generating index files. Background technique [0002] With the wide application of mobile terminals, the demand for playing videos through mobile terminals has increased significantly, and HTTP Adaptive Streaming (HTTP Adaptive Streaming, HAS) technology has also emerged as the times require. HAS technology combines traditional Real Time Streaming Protocol (Real Time Streaming Protocol, RTSP) / Real-time Transport Protocol (Real-time Transport Protocol, RTP) streaming media technology and progressive download based on Hyper Text Transfer Protocol (Hyper Text Transfer Protocol, HTTP) The advantages of technology are high efficiency, scalability and strong compatibility. [0003] The general idea of ​​the HAS technology is to transcode the video content into content of multiple bit rates, and then divide the...
