Problems solved by technology

When there are a large number of transmission packets to be processed, it is very likely that when the main task polls the buffer corresponding to a certain client, although the previous batch of data in the buffer has been processed, the new transmission packet has not been completely written. In the buffer, the main task detects that the buffer flag bit is not writable, and turns to query the next buffer status; after the new transmission packet is written, it needs to wait for the next round of query by the main task before it can be processed, thus losing the a processing opportunity
The method of transmitting data packets with a single buffer because the data packets wait for a long time to enter the buffer, so the efficiency of the entire broadcast server to process transmission packets is reduced

Embodiment Construction

[0044] see image 3 , the present invention relates to a method based on client / server architecture that adopts multiple buffers to improve data broadcast efficiency, taking double buffers as an example, its specific implementation process is as follows:

[0045] The client sends a connection creation request to the server through the client-server communication protocol, which includes the data type transmitted by the client and other related additional information;

[0046] The monitoring client connection task (task A) continuously monitors whether there is a client connection according to the TCP / IP protocol. When a new client connection is detected, a task (task B) is created to process the client request.

[0047] The server can handle client request tasks, maintain the communication between the client and the server, and process other requests sent by the client.

[0048] After the data broadcast server receives the client connection request, the working steps of task ...

Abstract

A method for increasing data transmission efficiency is designed based on the customer / server structure mounted in the system in front of a digital T, which processes the connection of customers, delivers data packets transferred from the customer end to its own buffer and plays data packets based on the transmission strategy to form a transmission flow to be sent to a multiplexer. This invented method applies the way of multiple buffers. Advantage: every customer end corresponds to more than one buffer to reduce the time of waiting for entering into the buffer by the data packet.

Description

technical field [0001] The invention relates to a method for improving the broadcasting efficiency of data streams, and belongs to the technical field of digital TV data broadcasting. Background technique [0002] Digital TV broadcasting technology is developing rapidly at present, compared with traditional analog TV, software technology occupies a more important position in digital TV technology. In addition to the decoding of video and audio by hardware, it includes the reproduction of TV content, the realization of the electronic program guide (EPG) operation interface, the realization of data broadcasting services, the interconnection of digital TV receiving equipment and personal computers, and the interconnection with the Internet. Even all need to be realized by software. The introduction of software technology in the digital TV era will greatly expand the business scope of traditional TV networks. [0003] Digital TV technology mainly includes two parts: digital TV...
