Multimedia data processing device and multimedia data processing method

Abstract

The embodiment of the invention provides a multimedia data processing method and a multimedia data processing device, wherein the device comprises a network bus base plate and a plurality of processing cards, the network bus base plate comprises a switch, a network interface connected with the switch and a plurality of network bus slots, the switch is connected with an articulated naturality web server of an articulated naturality web through the network interface and used for receiving multimedia data of the articulated naturality web server or transmitting the multimedia data to the articulated naturality web server through the network interface; the plurality of processing cards are connected the switch through the plurality of network bus slots, and are used for processing the multimedia data transmitted to the switch by the articulated naturality web server, and thereby obtaining the processed multimedia data. By application of the device and the method provided by the embodimentof the invention, the multimedia data processing device is provided with the plurality of processing cards, thus, capability of processing the multimedia data is improved, a phenomenon of coding and decoding delay or data packet dropout caused by scarce capacity of single terminal equipment is avoided, and a video conference can be played more smoothly on a display device.

Description

technical field [0001] The invention relates to the technical field of Internet of Things, in particular to a multimedia data processing device and method. Background technique [0002] At present, with the popularization and development of the Internet of Vision business across the country, the high-definition Internet of Vision interaction plays a pivotal role in government departments and other industries. The Internet of Vision adopts advanced real-time high-definition video switching technology to realize the real-time transmission of high-definition video in the whole network that cannot be realized by Ethernet at present. Dozens of video, voice, picture, text, communication, data and other services such as live broadcast, TV mail, and information release are all integrated into one system platform, and real-time interconnection of high-definition quality video communication is realized through a variety of terminal devices. [0003] In a video conference, the termina...

Problems solved by technology

[0003] In a video conference, the terminal device needs to collect and encode local multimedia data and send it to the Internet of Vision server. At the same time, it also needs to receive the multimedia data of the peer participant from the Internet of Vision server to decode and play it. When there are multiple participants In the case of participants, it is necessary to decode the multimedia data of multiple participants at the same time and then combine the screen and other processes, while video conferences usually use a terminal device to decode, encode, and combine the multimedia data generated by the video conference. This results in insufficient processing capacity of a single terminal device, resulting in codec delay or data packet loss, making the video conference appear on the display device as picture or voice delay, picture freeze, etc.
