System and method for implementing internet television medium interaction

Abstract

The invention discloses a method and a system to realize the interaction between the Internet and TV media, wherein, the method comprises that a user terminal sends a request of time-shift TV media files for videoing on demand, recorded broadcasting or live broadcasting to a marginal streaming media server of a point-to-point domain of the margin where the user terminal is located; the marginal streaming media to which the request is sent sends a first block of data of a target media file to the user terminal; after receiving the first block of data of the target media file, the user terminal starts immediately to play the first block of data of the media file and simultaneously requests the tables of node information which can provide the subsequent data blocks of the target media file from a content distribution network agent in the point-to-point domain of the terminal side where the user terminal is located; the content distribution network agent sends back the node information table which can provide the subsequent data blocks; and the user terminal requests to download and play the subsequent data blocks of the target storage file. The method and the system of the invention have the advantages of high service quality and being capable of reducing the load of a central streaming media server and the marginal streaming media server and reducing the construction cost.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a system and method for realizing Internet TV media interaction. Background technique [0002] Operators provide recording and broadcasting (TV On Demand, abbreviated as TVOD) and time-shifted TV (Time Shift TV, abbreviated as TSTV) services in the IPTV system, especially IPTV recording and broadcasting and time-shifting services in the metropolitan area (or even wide area) , is a huge challenge for operators. With the increasing popularity of standard-definition and even high-definition TV, the storage space occupied by IPTV live time-shifted TV and recorded programs is very large. To provide large-scale IPTV recording and broadcasting and time-shifting services in a metropolitan area or a wide area, the bottleneck of network bandwidth is a serious problem that must be faced. [0003] At present, services such as file download, Internet TV and VOD are provided on the In...
