Problems solved by technology

[0002] With the rapid development of network technology, two-way communication such as video conferencing and video teaching has been widely popularized in users' life, work, and study, and has played an active role in life and work applications. Or during audio interaction, multiple multimedia devices generate multiple multimedia data streams. At this time, one multimedia device cannot be used to generate a multimedia file. For example, the audio data and video data are respectively obtained through the audio device and the video device, and played after transmission. May appear out of sync, resulting in poor user experience

Abstract

The embodiment of the invention provides a multimedia data stream encapsulation method. The method is applied to an articulated naturality web, and the articulated naturality web includes an articulated naturality web multimedia terminal. The method includes the following steps: receiving a multimedia data stream from the articulated naturality web multimedia terminal; packaging the multimedia data stream into a data packet including multiple multimedia data frames according to an articulated naturality web protocol, wherein the articulated naturality web protocol includes an articulated naturality web multimedia data decoding format and an articulated naturality web multimedia data file transmission format; extracting a decoding time stamp (DTS) and a presentation time stamp (PTS) in thedata packet by using the articulated naturality web multimedia data decoding format; and encapsulating the data packet into a multimedia file in an articulated naturality web transmission format according to the decoding time stamp DTS and the presentation time stamp PTS. The purpose of encapsulating multiple pieces of articulated naturality web multimedia data into one complete multimedia file can be realized.

Description

technical field [0001] The invention relates to the technical field of Internet of Things, in particular to a multimedia data stream encapsulation method and a multimedia data stream encapsulation device. Background technique [0002] With the rapid development of network technology, two-way communication such as video conferencing and video teaching has been widely popularized in users' life, work, and study, and has played an active role in life and work applications. Or during audio interaction, multiple multimedia devices generate multiple multimedia data streams. At this time, one multimedia device cannot be used to generate a multimedia file. For example, the audio data and video data are respectively obtained through the audio device and the video device, and played after transmission. There may be out-of-sync phenomena, resulting in poor user experience. Contents of the invention [0003] In view of the above problems, embodiments of the present invention are prop...
