Video stream conversion and adaptive switching method and device, equipment and medium

Abstract

The invention discloses a video stream conversion and adaptive switching method and device, equipment and a medium. The video stream conversion method comprises the following steps: receiving a unicast video stream; configuring the unicast video stream according to preset configuration parameters, and converting the unicast video stream into a multicast video stream; and sending the unicast videostream address and the multicast video stream address to an electronic program guide server. According to the invention, the unicast video stream is converted into the multicast video stream; by adopting the multicast mode, the high unicast upper-layer network pressure in the prior art is relieved; compared with the prior art, the invention solves the problem of high equipment investment and network bandwidth occupation, reduces the burden of the server, and retains the unicast stream address and the multicast stream address, so that when multicast cannot be carried out normally, a unicast form is adopted to provide video service, the playing fluency is ensured, and the video watching experience of a user is ensured.

Description

technical field [0001] The present invention relates to the technical field of Internet television, in particular to a video stream conversion method, a video stream conversion device, an adaptive switching method, an adaptive switching device, computer equipment, and a computer-readable storage medium. Background technique [0002] OTT TV (hereinafter referred to as OTT) is referred to as Internet TV for short, and unicast is usually used for transmission in existing mainstream solutions. The advantage of unicast is that the server responds to user needs in a timely manner, and it is easy to realize personalized services, but the disadvantages are also obvious: for example, the pressure on the upper layer network is high when using unicast, CDN (CDN, content delivery network, content delivery network) equipment investment and network bandwidth occupation more. One of the solutions to this problem is to use multicast technology. Terminals using the same data stream join the...

Problems solved by technology

[0003] However, the multicast technology also has the following disadvantages: First, the terminal performance requirements are relatively high, and the terminal needs to record the multicast list, which requires high terminal performance

Moreover, the flexibility of recording the multicast list by the terminal is poor. If the multicast list is changed, firmware upgrade is required to realize it. Second, the requirements for the multicast stream are high. If there is a disconnection in the middle, it will seriously affect the user's viewing experience.
