Embodiment Construction

[0058] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0059] The system designed by the present invention is as image 3 As shown, it consists of several Da Vinci digital platforms connected together through the network. Each Da Vinci digital platform adopts ARM+DSP dual-core architecture, such as figure 1 As shown, ARM module 1 runs the main program as a general processor, and DSP module 2 is responsible for audio and video decoding as a coprocessor; wherein, ARM module 1 includes a P2P engine module 8, a player module 6, a UI module 5 and a control module 7. The P2P engine module 8 is responsible for obtaining the required audio and video data from the network. The player module 6 is responsible for playing the data obtained from the P2P engine module 8. The UI module 5 is responsible for providing a good interface for the user. The control module 7 and the UI module 5 , the player module 6 is connected...

Abstract

The invention relates to a method for realizing a DM6446-based embedded P2P live streaming media system with the advantages of reasonable design, high cost-performance ratio, excellent playing effect and the like. The system consists of a plurality of Vinci digital platforms which are connected with one another through a network, wherein each Vinci digital platform uses an ARM+DSP double core framework; an ARM module is a main running program of a general processor; a DSP module is a co-processor which is used for decoding audio and video; the ARM module comprises a P2P engine module, a player module, a UI module and a control module; the P2P is connected with an Ethernet and acquires required audio and video data from the network; the player module is used for playing the data acquired by the P2P engine module; the UI module is used for providing an excellent interface for a user; the control module is connected with the UI module, the player module and the P2P module and is used forcontrolling the running state of each module in cooperation with the UI module and responding to key operation on a remote controller by the user; the player module is connected with a display and anaudio device respectively; and the UI module is connected with the display.

Description

technical field [0001] The invention belongs to the technical field of network multimedia, in particular to a method for realizing an embedded P2P streaming media live broadcast system based on DM6446. Background technique [0002] With the development of computer network technology, streaming media has become a popular distribution method for multimedia files such as audio and video. The main difference between streaming media and conventional multimedia is that streaming media can be played while downloading. Streaming media live broadcast system can be widely used in video conferencing, remote training, radio and television and other fields. However, for these fields with large-scale potential users, the live streaming system of the traditional C / S (client / server) architecture has high requirements on server performance and network bandwidth, so the processing performance and network bandwidth of the server will become the extension of the entire system. the bottleneck....
