Problems solved by technology

[0002] In the application scenario where video input signal sources and output channels require as many as several video processing and transmission devices such as video splicers and matrices to participate in the control, due to the large number of input and output signal channels, the user's switching of input and output signal channels and The setting is very cumbersome, and requires the user to perform complex calculations on the physical connections between input signal sources, output channels, video splicers, and matrices. Sometimes incomplete calculations will also increase the cost of connected equipment

Abstract

The invention discloses a video input / output signal channel switching method and apparatus. The video input / output signal channel switching method at least includes: the step 1: receiving a command of a user for switching a video input signal source to any one video output signal channel of the Nth video processing transmission device from any one video input signal channel of the first video processing transmission device; the step 2: setting a logistic mapping relation for the respective video input signal channel and the respective video output signal channel of N video processing transmission devices; the step 3: calculating a set including paths of connection and connection number of the devices corresponding to the paths of connection; and the step 4: when a shortest path of connection exists in the set, providing the user with the shortest path of connection for application so as to realize switching of video input / output signal channels. The video input / output signal channel switching method and apparatus can partially solve the problems that how to simplify the setting modes for switching input / output signal channel and the calculating mode for physical connection, and can avoid pointless connection cost.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of video processing, and in particular, to a method and device for switching video input / output signal channels. Background technique [0002] In the application scenario where video input signal sources and output channels require as many as several video processing and transmission devices such as video splicers and matrices to participate in the control, due to the large number of input and output signal channels, the user's switching of input and output signal channels and The setting is very cumbersome, and requires users to perform complex calculations on the physical connections between input signal sources, output channels, video splicers, and matrices. Sometimes incomplete calculations will also increase the cost of connected equipment. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The main purpose of the embodiments of t...
