Problems solved by technology

However, since live video streams need to be transcoded before live broadcasting, in order to ensure the timeliness of the live broadcast, it will be very troublesome if you need to add a watermark. Usually, you need to perform relevant processing after transcoding to add watermark information, which may not be guaranteed. Timeliness

Embodiment 1

[0043] refer to figure 1 , is a flow chart of an embodiment of a video live broadcast method in the present invention.

[0044] A live video broadcasting method described in an embodiment of the present invention includes:

[0045] Step 100: transcoding the watermark, and generating a transcoded watermark;

[0046] Step 200: Superimpose the transcoding watermark on the transcoding output of the live stream, and perform live broadcast.

[0047] Through the method described in this embodiment, the watermark that needs to be added is transcoded before the live stream is transcoded, and the transcoded watermark is superimposed on the live stream after transcoding and output, so that the watermark information can be displayed in real time during the live broadcast.

[0048] In addition, for step 100, this embodiment can be specifically implemented as follows:

[0049] Step 110: Receive watermark information and live source stream information; for example, the received watermark ...

Embodiment 2

[0055] refer to figure 2 , is a structural block diagram of an embodiment of an apparatus of the present invention.

[0056] The device 1 described in the embodiment of the present invention includes: a watermark transcoding module 2 and a transcoding superposition output module 3 .

[0057] The watermark transcoding module 2 is used to transcode the watermark to generate a transcoded watermark;

[0058] The transcoding superimposition output module 3 is used to superimpose the transcoding watermark on the live stream for transcoding output.

[0059] In this embodiment, the watermark transcoding module 2 may further include: a watermark information acquisition unit 4 , a live source stream information acquisition unit 5 , a live source stream resolution analysis unit 6 , and a target watermark information generation unit 7 . Watermark transcoding unit 10.

[0060] The watermark information acquisition unit 4 is used to receive watermark information; for example, to receive...

Abstract

The invention discloses a video living broadcast method and device, wherein the method comprises: transcoding watermarks, and generating transcoded watermarks; and superposing the transcoded watermarks in live streaming for transcoding output and performing living broadcast. The method and device realize displaying watermark information in real time in a living broadcast process.

Description

technical field [0001] The present invention relates to the field of live video broadcasting, in particular to a method and device for live video broadcasting. Background technique [0002] Add watermark information in the process of video rebroadcasting. Generally, the watermark information is added to the video stream through post-production before rebroadcasting. Such a post-production process is not limited by time and does not affect the broadcast process. [0003] However, with the development of live video technology, the demand for adding watermark information during live video is becoming more and more intense. For example, watermark information is added to live video to protect copyright, or to promote some user advertisements. However, since live video streams need to be transcoded before live broadcasting, in order to ensure the timeliness of the live broadcast, it will be very troublesome if you need to add a watermark. Usually, you need to perform relevant pro...
