Data compensation method of streaming media of mobile terminal and data compensation system thereof, and content distribution network

Abstract

The embodiments of the invention disclose a data compensation method of a streaming media of a mobile terminal and a data compensation system thereof, and a content distribution network (CDN). The method comprises the following steps that: a personal computer (PC) sends a first node obtaining request message to a node scheduling server, receives a first obtaining response message returned by the node scheduling server, and determines whether there is a peer-to-peer (P2P) node storing low-bit rate content data of a streaming media program; if so, the low-bit rate content data of the streaming media program are downloaded from the P2P node and are stored; if not, the low-bit rate content data of the streaming media program are downloaded from a content server and are stored; the node scheduling server is required to add a first shared entry to a program shared state table, so that a follow-up mobile terminal can download the low-bit rate content data of the streaming media program from the PC. According to the embodiments of the invention, P2P sharing of content data of a streaming media program can be realized between a mobile terminal and a PC and thus sharing of the P2P can be effectively utilized to save network resources, thereby reducing the bandwidth stress and lowering system deployment and cost.

Description

technical field [0001] The present invention relates to communication technology, in particular to a mobile terminal streaming media data compensation method and system, and a content distribution network (Content Distribution Network, hereinafter referred to as: CDN). Background technique [0002] Streaming media refers to media formats played on the Internet (Internet) or Intranet (Intranet) in a streaming manner, such as audio, video or multimedia files. Streaming media does not download the entire file before playing, but only stores the beginning part of the content in the memory, and caches the data packets in the computer to make the media data output correctly. The data stream of streaming media is transmitted at any time and played at any time, but there is some delay at the beginning. Obviously, the key technology for the realization of streaming media is streaming transmission. Streaming transmission mainly refers to parsing the entire audio, video and 3D media a...

Problems solved by technology

Since P2P sharing can only be based on the unified coding format and the content data of streaming media programs at the same bit rate, the content data of streaming media programs can only be shared between PCs and between mobile terminals.

Since the mobile terminal streaming media is still in the common client / server (Client / Server, hereinafter referred to as: C / S) framework structure, it is impossible to effectively utilize P2P sharing, and the content data of the streaming media programs of the mobile terminal are all sourced In the content server, it causes a lot of bandwidth pressure on the content server, greatly wastes limited wireless network resources, and the system deployment and operation costs are high
