Embodiment Construction

[0025] The whole P2P transmission and broadcasting system of the present invention, such as figure 1 As shown, the system consists of four main parts: P2P quantum packet encapsulation server, embedded P2P set-top box, P2P management system and Internet.

[0026] The P2P quantum packet encapsulation server divides and encapsulates continuous TS streaming media or files into several quantum packets, labels all quantum packets in a continuous order, and marks the quantum packets with time stamps according to time points. The encapsulated quantum packet is stored in the quantum packet encapsulation server, which is used as a data source or seed quantum packet for P2P interface content or TV channels, and is available for downloading by the certified embedded P2P set-top box. When an embedded P2P set-top box becomes a P2P network node on the Internet, it sends request information to the P2P management system and obtains authentication, establishes a communication link with the quan...

Abstract

The invention is a technology of an embedded P2P set-top box and an implementation method thereof. Through a quantum package packaging a server, and various files such as a consecutive transmission stream format (TS) and media, etc. are packed into a quantum TS stream media package (the quantum package), through the certification and the management of a P2P management system, all embedded P2P set-top boxes transmitting on the internet are matched and grouped. As the adjacent group of P2P network nodes, each P2P network node can download from other nodes and share one group of quantum package having the same sequence mark with other nodes, in the same time-stamp mark, the quantum package is restored to the consecutive stream media file through a decoder according to the consecutive marks, and the application of an equivalent node (P2P) technology in the set-top box is realized.

Description

technical field [0001] The invention relates to the field of multimedia technology and the Internet, and the related technologies include: peer-to-peer node (P2P) technology, digital video compression technology, streaming media technology, embedded system and software technology, and the like. In addition, the invention also relates to the technical field of broadcasting and television. Background technique [0002] As a network multimedia terminal, embedded IPTV set-top boxes have been widely used in Internet Television (IPTV) systems. However, when IPTV set-top boxes guarantee service quality and broadband applications, bandwidth guarantees are required. Operators need to transform existing networks on a large scale. It is almost impossible to directly use IPTV set-top boxes on the Internet. However, the use of P2P technology can share network resources and storage resources, and overcome the limitations of bandwidth and network distance. P2P technology implemented by co...
