WiFi coding optimization method and system thereof

Abstract

The present invention relates to a WiFi (Wireless Fidelity) coding optimization method, including the steps of: providing channel information and electric program menus for a client through a transmitting server; initiating a transmitting request to join in by the client; determining whether the signal quality can meet predetermined requirements when the client receives a media data packet, if not, initiating a transmitting request to join in a FEC (Forward Error Correction) flow; the client carrying out a verification on the media data packet according to an FEC data packet after receiving the FEC data packet, and then reorganizing the media data packet. The invention also relates to a WiFi coding optimization system. The application of the invention can improve the correctness of the media data reception by avoiding the use of packet loss retransmission mechanism, enhance the usage rate of broadband, and reduce the terminal power consumption. At the same time, the cost reduction can be realized because the verification data is sent through business layer and a hardware modification is unnecessary.

Description

technical field [0001] The present invention relates to the technical field of signal transmission coding, in particular to a method and system for optimizing signal transmission coding in WiFi data broadcasting. Background technique [0002] Due to the influence of wireless environment interference on WiFi broadcast and multicast services, bit errors may occur in an environment with weak signal strength. Since there is no technology such as forward error correction in the WiFi standard to correct the transmission code, the 802.11 protocol stipulates that the adjustment rate can be used to adapt to user reception in different reception environments and improve the accuracy of received data. When the received data is incorrect, the network card at the receiving end requests retransmission at the data link layer, but retransmission processing will waste bandwidth and consume terminal power. [0003] In order to overcome the defects of retransmission processing, the 802.11e pr...

When the received data is incorrect, the network card at the receiving end requests retransmission at the data link layer, but retransmission processing will waste bandwidth and consume terminal power

[0003] In order to overcome the defects of retransmission processing, the 802.11e protocol adds priority processing and modulation layer processing at the MAC layer, and supports RS FEC coding, but these processing methods of the 802.11e protocol cannot be obtained based on other 802.11 protocols (such as 802.11a or 802.11b protocol) AP support, so there is a certain hardware dependence. If the existing 802.11e protocol processing method is implemented, the existing network needs to be changed, and the implementation cost is relatively high
