AI Technical Summary

Problems solved by technology

However, loss of image frames may occur during the transmission of image frames. For example, wireless fidelity (Wireless Fidelity, WiFi) is used to carry IPTV services in a home network. Due to the poor anti-interference ability of WiFi itself, the signal stability is poor. , leading to a high random packet loss rate of WiFi transmission data, and an increased possibility of image frame loss
The loss of the I frame in the transmitted image frame will cause a black screen for a long time, and the loss of the P frame will cause a blurred screen, which reduces the service quality of IPTV

Embodiment Construction

[0034] Embodiments of the present application provide a data transmission method, device, network access device, and storage medium, which can be applied to IPTV services, such as IPTV live broadcast services. figure 1 It is a schematic diagram of a data transmission application scenario in the embodiment of this application. Such as figure 1 As shown, the data transmission system includes a service server 11 , a network access device 12 and a user terminal 13 . Wherein, the service server 11 may be an IPTV head-end server, and the programs of the channels are stored on the service server. Specifically, the service server 11 may be a device such as a remote server. The network access device 12 may specifically be an optical network terminal (Optical Network Terminal, ONT), a gateway, a wireless access point (Wireless Access Point, AP) and other devices. Specifically, the user terminal 13 may be a device such as a set top box (Set Top Box, STB). The user terminal 13 sends t...

Abstract

The present application provides a data transmission method, device, network access device and storage medium, and relates to the technical field of communication. The data transmission method includes: the network access device intercepts the channel parameter information issued by the service server to the user terminal, and detects whether the channel parameter information indicates that the user terminal enables the forward error correction FEC receiving function; if the channel parameter information does not indicate that the user terminal activates With the FEC receiving function, the network access device obtains the network performance parameters of data communication between the service server and the user terminal; the network access device detects whether the network performance parameters meet the network performance deterioration conditions; if the network performance parameters meet the network performance deterioration conditions, the network The access device controls the user terminal to enable the FEC receiving function. The technical scheme of the present application can avoid loss of image frames, thereby improving the service quality of IPTV.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data transmission method, device, network access device and storage medium. Background technique [0002] Internet Protocol Television (IPTV) is a new technology that utilizes the network and integrates technologies such as the Internet, multimedia, and communication to provide a variety of interactive services including digital TV. Data is transmitted from the service side equipment to the user terminal. For example, if the service-side device provides an image service to the user terminal, the service-side device sends the image frame to the user terminal. Image frames can be divided into three types according to coding, namely I frame, P frame and B frame. Wherein, an I frame is a completely coded frame. A P frame is a frame generated with reference to an I frame preceding the P frame and coded up to and including a difference from the I frame. A B fr...
