Abstract

The invention discloses a method for achieving functions of fast forward, fast backward and accurate Seek in an HLS protocol in an expanding mode. The method comprises the following steps that I-frame record information is obtained, I-frame description information is organized, all I-frame record information stored when a medium is fragmented is organized according to a certain form, and all the I-frame record information contained in each fragment is organized and named as the I-frame description information of the fragment; the I-frame description information is recorded in the M3U8 expanding mode, the I-frame description information of each fragment is stored in an M3U8 file so that a client side can obtain the I-frame description information of each fragment, and therefore the client side obtains the M3U8 file and the I-frame description information of each fragment; the client side accurately controls playing according to M3U8 expansion information. The method can solve the problem of accurate control over accurate Seek, fast forward playing and fast backward playing in an OTT mobile video service system, achieves the purposes of smooth play and random play, and improves digital media life experience.

Description

technical field [0001] The present invention relates to the technical field of streaming media communication, in particular to a mobile video service system based on the open Internet, and its control methods for fast forward, fast push and fine Seek operations in live broadcast, on-demand and time-shifting, and belongs to digital The field of media life technology. Background technique [0002] The OTT mobile video service based on the open Internet is one of the best solutions to meet the needs of many applications such as live broadcast (Live), on-demand (OnDemand) and time-shift (TimeShift) in the future. OTTTV is the abbreviation of "OverTheTopTV", which refers to video services based on the open Internet. The terminals can be TVs, computers, set-top boxes, PADs, smart phones, etc. It means providing services on the network, emphasizing the independence of services from physical networks. At present, the usual practice is to divide and package the media data into diff...
