At this point, step S102 can be implemented as the following step S1021:

In step S1021, when receiving an operation instruction from the user to disable playback generation, after the live broadcast ends, remove at least one marked video segment from the video generated during the live broadcast and generate playback.

When the operator starts the live broadcast, the cloud broadcasting station will automatically record the start time, and you can set whether playback is required. When playback is required, the user can, for example, turn on the button to generate playback. After receiving the operation instruction, the cloud broadcasting station will generate the video live broadcast. Playback, the user can mark one or more video clips during the live broadcast, and the marked video clips will not generate playback, and the user can control certain video clips in the live broadcast by clicking the buttons that do not need playback start and do not need playback end No playback is generated. In this way, redundant segments in the live broadcast process can be easily removed, and the secondary transmission rate of playback can be improved.

In one embodiment, as shown in FIG. 3, the live playback method may further include the following step S104:

In step S104, it is detected whether an operation instruction of closing the generated playback by the user is received.

At this time, step S102 can also be implemented as the following step S1022:

After the cloud broadcasting station receives multiple video signals, it synthesizes the multiple signals into one signal, that is, each frame in this signal is composed of the content of each channel. Using one player to play this signal, multiple video signals can be simultaneously combined. The content of the road signal is presented to the audience. In addition, the cloud director station will also automatically record the user's switching video stream operation, and then generate a playback of the switching process.

Because different video sources have inconsistent frame rates, that is to say, the frame rates of different video screens played by the same player may not be the same. Therefore, when the player of the cloud director station plays, it can play according to the time stamp of the video. The player obtains the video frames with the same time stamp of each channel of video for splicing and playing. The method of playing according to the time stamp is equivalent to normalizing, or standardizing, the frame rate of each channel of video images. Then, the frames of each channel of video are played at the standardized frame rate, so that the frames of each video have a sense of synchronization.
