Problems solved by technology

[0004] At present, when users use IPTV, they can only request to download or play media files from the CDN server (Content Delivery Network, content distribution network) through the set-top box alone, but cannot download and play at the same time. Or the playback mode will cause a lot of bandwidth to be idle, which cannot meet the needs of users for IPTV services

Abstract

The invention discloses a method, a terminal, a CDN server and a system for realizing downloading while playing in an IPTV system. The method includes: the terminal obtains code rate information of a media file requested to be played from a content distribution network CDN server, and the CDN The server returns the first response message to the terminal after receiving the request, which carries the code rate information of the media file requested by the terminal to play, and the terminal judges whether the code rate information satisfies the condition of downloading while playing, and if it satisfies , then request to the CDN server to download the file to be downloaded by the user while playing the media file, the method, terminal, CDN server and system provided by the present invention realize the downloading of the media file at the same time without affecting the viewing of the user , make full use of the user's network resources, improve user experience, and bring diversified value-added services to operators.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, a terminal, a CDN server and a system for realizing downloading while playing in an IPTV system. Background technique [0002] IPTV, or Interactive Network Television, is a brand-new technology that utilizes broadband cable TV network and integrates Internet, multimedia, communication and other technologies to provide home users with various interactive services including digital television. Users can enjoy IPTV services in two ways at home: (1) computer, (2) network set-top box + ordinary TV. It can well adapt to the rapid development trend of today's network and make full and effective use of network resources. IPTV transmits TV, video, text, graphics and data on the IP network, and provides manageable multimedia services with quality of service / service experience assurance, security, interactivity and reliability. It can be seen from this that IPTV is a manageable...
