Abstract

The present application discloses an IPTV 4K audio and video playback management method, device, and display device. The method includes: reading and parsing 4K audio and video data; acquiring RTP serial numbers of the parsed audio and video data; judging whether the RTP serial numbers are continuous; If the RTP serial number is continuous, the audio and video data corresponding to the RTP serial number is sent to the audio and video module for playback; if the RTP serial number is not continuous, it is determined whether the RTP serial number has expired; if the RTP serial number has expired, the audio and video data corresponding to the RTP serial number will be discarded, and Send the agreed return value to the audio and video reading module. The present application determines whether the audio and video data is retransmission data by judging whether the RTP sequence number is continuous and whether the RTP sequence number is expired, and discards the retransmitted audio and video data, thus reducing the data retransmission rate and reducing the invalid data in the data packet , which effectively avoids the 4K video playback freeze, makes it clear and smooth playback, and greatly improves the video playback quality.

Description

technical field [0001] The present application relates to the technical field of set-top boxes, and in particular, to an IPTV 4K audio and video playback management method, device, and display device. Background technique [0002] IPTV (Internet Protocol Television, interactive network television) is a broadband network, using DSL (Digital Subscriber Line, digital subscriber line) or Ethernet and other access methods, through the network set-top box or PC to provide users with a variety of interactive Broadband audio and video services, including audio and video live broadcast, audio and video on demand, games, audio and video conferences and other services. [0003] With the introduction of high-definition and large-stream 4K live channels, multicast replication based on BRAS (Broadband Remote Access Server, broadband remote access) is difficult to meet the needs of large-scale 4K live channel users, and the network access method needs to be transformed. Users of the origi...
