Abstract

A method for control program signals Devices and Systems, The method is applied to the communication between the broadcast device and the control terminal. The control terminal is provided with a visual control interface. The method comprises the following steps: receiving the operation information sent by the control terminal, the operation information being generated according to the drag and drop operation or batch selection and transmission operation of the target program by the worker on the visual control interface; according to the operation information, determining a target program ona preset input port program relation tree at a time before receiving the operation information, and determining a target port on a preset output port program relation tree at a time before receivingthe operation information; sending the program signal corresponding to the target program to the target port to alleviate the technical problem of the low efficiency of the program signal control process existing in the prior art, and the technical effect of improving the program signal control process efficiency is achieved.

Description

technical field [0001] The present invention relates to the technical field of radio and television, in particular to a program signal control method, device and system. Background technique [0002] Radio and television is a communication medium that broadcasts audio and video programs to a wide area through radio waves or wires, collectively referred to as broadcasting. Those that broadcast only sound are called sound broadcasts; those that broadcast images and sounds are called television broadcasts. In the process of broadcasting images and sounds by broadcasting and television, it needs to involve the processing processes of program signal encoding, decoding, transcoding, routing and multiplexing. [0003] When these processes are completed, the broadcasting device needs to send the program signal from the input interface (including multiple input ports) to the output interface (including multiple output ports) according to the operation information of the staff. In p...
