Example Embodiment

[0089] Example one

[0090] In the first embodiment, after obtaining the guide data collected by the physical camera and the virtual camera, LOGO and subtitles are added and sent to the server in a multi-link parallel transmission manner. See figure 2 As shown, the specific process is as follows:

[0091] Step 201: Obtain the guide data collected by the physical machine position and the virtual machine position.

[0092] Step 202: Obtain the frame-selected picture material through the online webpage, and determine the subtitle data at the same time.

[0093] Step 203: Use video keying technology to add LOGO and subtitles to the guide data.

[0094] Step 204: Determine whether the guide data needs to be decoded. When the guide data needs to be decoded, proceed to step 205, otherwise proceed to step 207.

[0095] Step 205: Decoding the guide data to obtain guide data parameters.

[0096] Step 206: Set the parameters of the encoder according to the obtained guide data parameters, and re-en...

Example Embodiment

[0132] Example two

[0133] In the second embodiment, the live broadcast director system has three physical camera positions and one virtual camera position, a total of four video sources, and the final data to be processed can be selected by key operation. The live broadcast director client splits the live stream data and sends it to the server in a multi-link parallel transmission manner. The server integrates the data and then sends it to the target system in a rectified transmission manner. Among them, the physical camera is an external physical camera, which is connected to the live broadcast director client through an interface. See Image 6 As shown, the process is as follows:

[0134] Step 601: The live broadcast director client sends a SYN packet to the server, and the live broadcast director client enters the SYN_SENT state, waiting for the server to confirm.

[0135] Step 602: The server confirms the received SYN packet, and sends a SYN / ACK packet to the live broadcast d...

Abstract

The invention discloses a live broadcasting instruction method, a client and a system. The method comprises steps: broadcasting instruction data are acquired, wherein the broadcasting instruction data comprise data acquired by a physical camera position and/or data acquired by a virtual camera position; editing processing is carried out on the broadcasting instruction data, and live streaming data are determined; according to an instant transmission ability of a transmission link, distribution is carried out on the live streaming data, and sequence block markers are added to live streaming data blocks acquired after distribution; and the live streaming data blocks are scattered in different transmission links and are sent to a target address in a multilink parallel transmission mode. The multilink parallel transmission mode is adopted for transmitting the live streaming data, live streaming transmission is carried out through integrating multiple network links, the network bandwidth is used maximally, the transmission rate is improved, and timeliness and fluency of the live streaming can be ensured.

Description

technical field [0001] The present invention relates to the technical field of audio and video transmission and processing, in particular, to a method, client and system for directing live broadcast. Background technique [0002] The broadcasting technology refers to that each video signal is transmitted to a device called a "video switcher" through a signal line. The "video switcher" is operated by the "TV program producer" to select one of the multiple signals to output to the video recorder according to the "TV performance rules". After the filming is completed in this way, the first compilation of the TV program is completed. In the process of multi-signal directing, the selection of different lenses and different camera positions also determines the expressiveness of the screen presentation of film and television works. This kind of on-site switching work is the "director". [0003] After the video screen being captured is broadcasted through the guide, it will be tr...
