example 1

[0055] In the live recording and broadcasting system, the remote control device is a remote control with at least three buttons. The three buttons are video switching button, scene selection button and screen confirmation button, wherein the video switching button corresponds to the video switching unit of the remote control device, and the scene selection button Corresponds to the scene selection unit of the remote control device, and the screen confirmation button corresponds to the recording unit of the remote control device.

[0056] After entering the network guide, you can switch the video source of the guide screen by using the video switching button on the remote control. When it is necessary to quickly call the camera's preset position to realize the shooting of the preset scene, the user can first use the video switch button to select the camera screen, and then use the scene selection button to quickly switch the camera's preset position. If the courseware display d...

[0072] Figure 5 It is a schematic diagram of video data flow of a broadcasting system in an embodiment of the present invention, Figure 5 Among them, VI is video input, VPSS is video processing, VENC is video encoding, VDEC is video decoding, and VO is video output.

[0073] refer to Figure 5 , by inputting the uncompressed high-definition video data of three cameras from the outside of the directing station and one uncompressed high-definition courseware video stream sent from a desktop / laptop, a total of four high-definition uncompressed video data exist in the directing station at the same time. In addition, the broadcast guide station also receives a channel of compressed and transmitted video data from the network or local mobile terminal wireless projection, and decodes and restores it in the broadcast guide station. It can be seen from this that there are a total of five channels of video data options in the broadcasting station for switching between broadcasting d...

Abstract

The embodiment of the invention provides a director system and a recording and live broadcasting system, wherein the director system comprises a plurality of cameras, a director station and a remote control device, wherein each camera is connected with the director station, and the director station is connected with the remote control device; the remote control device comprises a video switching unit, the video switching unit is used for sending a video switching instruction to the director station, and the video switching instruction comprises a target video source; the director station is used for receiving video data shot by each camera and the video switching instruction and switching a director picture to the video data which are corresponding to the target video source and shot by the cameras according to the target video source in the video switching instruction. According to the director system and the recording and live broadcasting system provided by the embodiment of the invention, the operational process of the manual director system is simplified, and the operational threshold of the manual director system is reduced, so that non-professional director personnel can realize high-quality video broadcasting through the remote control device as well, and large-scale population and application of the manual director system is facilitated.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of video processing, and in particular to a broadcast guidance system and a live recording and broadcasting system. Background technique [0002] With the continuous development of video processing technology and the Internet, the demand for broadcast guidance systems is also growing. [0003] At present, the existing guidance system includes two kinds of automatic and manual. Among them, the fully automatic broadcasting system relies on tracking and positioning technology plus a certain switching strategy to move and switch the lens. Since tracking and positioning are easily disturbed, it has high requirements for the environment and scenes, and requires the cooperation of participants to use it effectively, which is not smart enough. And can not reflect the individual's characteristic, the actual use effect is very poor at present. [0004] Therefore, in important occasions that...
