Problems solved by technology

The traditional way of building a TV wall has the following defects: First, the establishment of a TV wall requires a front-end video image splitter device; Second, the function of the TV wall is subject to the splitter, such as the image display effect of the TV wall is subject to the splitter The performance, the signal source supported by the TV wall is limited by the video signal source supported by the splitter, and often does not support high-definition signal source or digital video signal source, which

Embodiment Construction

[0025] Refer below Figure 1 to Figure 8 Specific examples of the present invention will be described.

[0026] refer to figure 1 , in this embodiment, the TV wall 1 includes four TV sets 11, 12, 13, 14, stacked to form a 2×2 large TV wall 1; the TV signal input terminal of the TV signal distributor 2 is connected to an external TV signal Source, the TV signal source can be an ordinary TV signal source, a high-definition TV signal source, a digital TV signal source, the four-way TV signal output terminal of the TV signal distributor 2 and each TV set 11, 12, 13, The signal input end of 14 is connected, and the four-way TV signal of its output is equal to the one-way TV signal of input, and this TV signal distributor 2 is a common technology, and its function is only to divide one-way TV signal into multiple channels equal to the original TV signal TV signal; the audio equipment 3 is connected to the audio output end of one of the TV sets 12, and is used to play the synchrono...

Abstract

The invention relates to a method for building television wall, which comprises: layering several televisions into TV wall, while each one has image zoom processor; setting the position parameter and image zoom parameter of each television inside the TV wall; transmitting same TV signal to each television; when each TV digitalizes the received signal, the image zoom processor, based on the image zoom parameter and the resolution of screen, expands the image, and based on the zoom parameter and position parameter, calculates out the shift parameter of present displayed image, based on said shift parameter, shifts it to appointed image area to be output to the screen; different TVs displays the different areas of one image that zoomed at same ration, to be layered to form the TV wall; and the sonic processing circuit in one TV can synchronously process the sonic signal, to output it to the sonic device to be played. Compared with present technique, the invention has lower cost and simple process.

Description

technical field [0001] The invention relates to a video wall, in particular to a method for building a video wall and a video wall realized by the method. Background technique [0002] In order to meet the special needs of some occasions, such as shopping malls, public places, outdoor advertisements, conference halls or studios, etc., in order to provide special information and meet the needs of people to see the image information clearly at a distance, it is often necessary to place some large-scale images Display devices, and the current image display devices usually use TV sets, it is difficult to achieve such a large size, so usually multiple TVs are arranged in a certain ratio to form a wall to achieve the purpose of large-size display screens, commonly known as TV Wall. [0003] The traditional implementation method is to divide the video signal according to the ratio of the number of TVs in the TV wall before inputting the video signal to the TV wall, and then enlarg...
