Output-oriented network transmission technique of multi-screen splicing system

Abstract

The invention relates to an output-oriented network transmission technique of a multi-screen splicing system. The core of the technique is output-oriented smart segmentation and accurate transmission; in other words, segmentation processing is performed on signals in a smart way according to the requirements of output display, and then each part of data is accurately transmitted to a corresponding display unit. The technique comprises the following main steps that: step 1, an input acquisition end processor (2) acquires a signal from a signal source (1), and performs compression processing on the corresponding signal according to a display policy sent by a control host (5); step 2, the acquisition end processor (2) segments the signal according to the display policy, compresses and packs the segmented image data and then transmits the same to an output display end through a network; step 3, a display end processor (3) unpacks and decodes the data and performs amplification processing on the signal according to the display policy; and step 4, the display end processor outputs and displays the image on a corresponding spliced display screen (4). In the whole process, the data is segmented in advance at the input end and each part of data is accurately transmitted to the corresponding display unit; and the compression of the signal is completed at the input end while amplification is realized by the output end; therefore, the data in the whole network system is transmitted at the lowest flow rate and the waste of bandwidth is avoided.

Description

technical field [0001] The invention relates to the field of multi-screen splicing display of images, in particular to an output-oriented multi-screen splicing system network transmission technology. Background technique [0002] At present, with the development of video splicing display technology, large-screen splicing video walls have gained more and more favor for their high-definition, vivid colors, and large-screen effects. The high resolution of the splicing large screen can convey more information, and can meet the needs of real-time monitoring, command and dispatch, report display, advertising and other aspects, and has been widely used in a large area. [0003] The existing splicing display technology is usually realized in the following way: the data acquisition terminal of the splicing image processor samples and encodes the image information of the signal source, transmits the data to the processor memory through the system bus or network, and then according to ...
