Problems solved by technology

However, on the basis of the inherent network transmission speed and hardware processing speed, the number or number of channels that can simultaneously play interactive videos in real time is limited. Lianmai
In addition, in the process of video transmission, video fusion may be out of sync due to loss of video data due to various reasons such as network delays, device freezes and other technical reasons

Embodiment 1

[0048] Example 1: Merge the missing area according to the black screen. The advantage of this processing method is that the processing method is simple, but the disadvantage is that the user experience is not good.

Embodiment 2

[0049] Embodiment 2: filling with video frames before the time of the missing region, or filling with video frames after the time of the missing region. This processing method is also relatively simple, but the user experience still has subtle deficiencies, because the missing area is a static video image, which looks relatively rigid.

Embodiment 3

[0050] Embodiment 3: Use the video frames before and after the time of the missing region to perform difference. The disadvantage of this method is that each pixel needs to be calculated for the difference, the amount of calculation is large, and it is difficult to meet the real-time requirements.

Abstract

The invention provides a multi-channel real-time interactive video cache storage method. The method comprises the following steps of acquiring K channels of real-time videos through K real-time videosources; the anchor video source sending the video synchronization request information to the slave video source; responding to the received video synchronization request information, sending responseinformation to the anchor video source from a slave video source, and obtaining global time from a global clock server; when the anchor video source receives the response information, obtaining the global time from a global clock server; the anchor video source transmitting the acquired anchor video and the global time to the distributed server, and the slave video source transmitting the acquired slave video and the global time to the distributed server; and the distributed server inserting the received videos into the corresponding positions of the corresponding cache synchronization queuesaccording to the received global time. According to the method, video fusion synchronization can be ensured, the real-time performance is good, and the user experience is good.

Description

technical field [0001] The invention relates to a video cache storage method, in particular to a multi-channel real-time interactive video cache storage method. Background technique [0002] In the case of a certain network bandwidth, the playback of real-time video is mostly realized by caching technology. When multiple channels of real-time interactive video are played on the same client, different network paths exist in the transmission of each channel of real-time video, resulting in different network delays, which in turn cannot achieve better results when played on the same client. synchronization. The solution in the prior art is to increase the network transmission speed and hardware processing speed through the design of network architecture and topology, so as to eliminate or alleviate the transmission delay of each real-time video as much as possible. However, on the basis of the inherent network transmission speed and hardware processing speed, the number or nu...
