Video transmission device

Abstract

The invention discloses a video transmission device which comprises a video data acquisition unit, a quality threshold value setting unit, an encryption unit, a load data information loading unit, a transmitter and a plurality of receivers. The video data acquisition unit is used for acquiring video data. The quality threshold value setting unit is used for determining the quality threshold value of the vide data needing to be transmitted and enabling the quality threshold value meeting requirements to serve as preset threshold value. The encryption unit is used for encrypting the video data reaching the preset threshold value. The load data information loading unit is used for adding effective load data information on the head portion of the encrypted video data. The transmitter is used for sending the encrypted video data which is loaded with the effective load data information to the plurality of receivers in a time synchronization mode. The video transmission device has the advantages that the quality of the video is guaranteed by setting of the quality threshold value, and the problem of live transmission of the video data is solved through the synchronous transmission time.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a video transmission device. Background technique [0002] With the increasing development of the Internet, more and more people use online video to replace traditional TV programs. The video service has become the service with the largest Internet traffic, and it will be the main business form that will dominate Internet applications in the future. However, with the continuous growth of video traffic, while providing rich information, it also occupies the network transmission bandwidth, causing obstacles in the speed of network transmission, and cannot transmit in real time. [0003] In the prior art, the amount of transmitted data can be reduced by compressing and transcoding video data, and the transmission delay of video data can be reduced, thereby avoiding network congestion, but the problem of real-time transmission of video data cannot be completely...

However, with the continuous growth of video traffic, while providing rich information, it also occupies the network transmission bandwidth, causing obstacles in the speed of network transmission, and cannot transmit in real time

[0003] In the prior art, video data can be compressed and transcoded to reduce the amount of transmitted data and reduce the transmission delay of video data, thereby avoiding network congestion, but it still cannot completely solve the problem of real-time transmission of video data
