Abstract

The invention provides a method for identifying a video signal, a system and video terminal display equipment, which is applicable to the field of the signal identification. The method comprises the following steps of: obtaining the line field information of an input video signal, receiving the information of a video type inputted by a client, making a comparison between the line field information and line field information corresponding to the video type inputted by the client and taking the input video signal as the video type inputted by the client when the line field information are the same. In the embodiment of the invention, the client directly inputs the video type after the line field information of the input video signal is obtained, and only making the comparison between the line field information obtained and the line field information corresponding to the video type inputted by the client is required, thereby simplifying comparing process of the line field information and saving the identifying time of the video signal.

Description

technical field

[0001] The invention belongs to the field of signal recognition, and in particular relates to a video signal recognition method, system and video terminal display device. Background technique

[0002] With the development of video signals, there are more and more types of video signals, such as RGB, DVI, YPBPR, etc. When a video terminal display device receives a video signal, it needs to identify the received video signal and determine the type of the received video signal. At present, the video terminal display device identifies the type of the input video signal according to the line and field information of the input video signal. The method for identifying a video signal includes: Step 1: Obtain line and field information of the video signal. Step 2: Compare the line and field information with the line and field information of each video type supported by the video terminal display device one by one, and find out the video type that best matches the in...

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] In the embodiment of the present invention, after the field information of the input video signal is obtained, the video type is directly input by the user, so it is only necessary to compare the obtained field information with the field information corresponding to the video type input by the user. When the information is the same, the input video signal is the video type input by the user.

[0021] figure 1 The identification process of the video signal provided by the embodiment of the present invention is shown, and the details are as follows:

[0022] In step S101, line and field info...
