Problems solved by technology

When there are at least two upload controllers, since the video recorder and video server encoding channel can only be controlled by the corresponding upload controller, the operator can only select the video recorder and video server encoding channel controlled by the upload controller after logging in the upload controller When performing upload tasks, it is impossible to operate the video recorders and video server encoding channels in the idle state controlled by other upload controllers, resulting in waste of resources

Embodiment 1

[0041] When realizing the control method of uploading the video and audio signal, the video and audio signal to be uploaded can be the video and audio signal played by the video recorder, or it can be the access of the live signal sent back by satellite access, studio signal access, and OB vehicle , or the line signal of each TV channel program access. This embodiment specifically describes the control method for uploading video and audio signals when the video and audio signals to be uploaded are video and audio signals played by video recorders, such as Figure 4 As shown, the method includes the following steps:

[0042]401. The upload control machine sends a query instruction to the device control server.

[0043] 402. The device control server performs a query according to the query command, finds out video recorders and video server coding channels in an idle state, and returns query results including the video recorders and video server coding channels to the upload co...

Embodiment 2

[0066] Corresponding to Embodiment 1, it can be seen that this embodiment specifically describes when the video and audio signals to be uploaded are accessed through satellite access, studio signal access, live signal access sent back by OB vans, or line signals for channel program access of various TV stations. Implemented video and audio signal upload control methods, such as Image 6 As shown, the method includes the following steps:

[0067] 601. The upload control machine sends a query instruction to the device control server.

[0068] 602. The device control server performs an inquiry according to the inquiry instruction, inquires out the encoding channel of the video server in an idle state, and returns an inquiry result including the encoding channel of the video server to the upload controller.

[0069] 603. After receiving the query result returned by the device control server, the upload control machine selects an encoding channel of the video server that is in an ...

Embodiment 3

[0089] This embodiment provides an upload control machine, such as Figure 8 As shown, the upload controller includes: a selection unit 81 , a sending unit 82 and a receiving unit 83 .

[0090] When the video and audio signal to be uploaded is the video and audio signal played by the video recorder, before the upload task is started, the sending unit 82 is used to send a query instruction to the device control server, and the receiving unit 83 is used to receive the query result returned by the device control server, The query result includes video recorders and video server encoding channels in an idle state queried by the device control server. The selection unit 81 is used to select the aforementioned video recorder and video server encoding channel in an idle state.

[0091] The sending unit 82 is also used to send a switching instruction to instruct the matrix control server to control the video and audio matrix to connect the route between the selected video recorder an...

Abstract

The invention discloses a control method, devices and system for uploading video and audio signals, relating to the technical fields of video and audio and solving the problem that in the prior art, a video server coding channel can not be shared. In the embodiment of the invention, at least two uploading controllers are respectively connected to the same equipment control server and the same matrix control server. The control method comprises the following steps: selecting the video server coding channel in an idle state; sending a switching instruction to the matrix control server and indicating the matrix control server to control a video and audio matrix to be communicated with a route between an output channel of the video and audio signals to be uploaded and the selected video server coding channel; sending a first starting instruction to the equipment control server and indicating the equipment control server to control the selected video server coding channel to code the video and audio signals to be uploaded. The embodiment of the invention is mainly applied to the technical fields of video and audio and realizes the shared use of the video server coding channel when the video and audio signals are uploaded.

Description

technical field [0001] The invention relates to the field of video and audio technology, in particular to a control method, device and system for uploading video and audio signals. Background technique [0002] In the uploading process of video and audio signals, it is necessary to select a certain control method and use a series of devices to complete the uploading task of the entire video and audio signals. For example, in the program broadcasting of a TV station, the video and audio signals of the program are generally first uploaded to a video server, and then the program is broadcasted through the video server. [0003] The existing technology provides a method of directly controlling the video recorder and video server encoding channel through the upload controller to realize the video and audio signal upload of the complete program. The specific process is as follows: [0004] The upload control machine establishes connection with the video recorder and the encoding ...
