Problems solved by technology

[0002] In the existing multi-screen signal processors (or systems), the processing of signals is still mainly analog signals, and the processing ability of digital signals is weak; most products can only process one or a few digital signals; even Some products perform D / A conversion on digital signals and then process them in the same way as analog signals
And usually use special data paths and processing methods for some signals. In a complex processing environment that can handle multiple signals, there may be multiple data paths, processing methods and control methods at the same time, which increases the complexity of control and processing. , it is usually difficult to add a new signal processing method
[0003] In the existing ultra-high-resolution display environment using multiple display output channels, when processing digital signals, one processing device is usually connected to multiple display devices, and the information processed by the processing device is sent to When the display device performs display and the processing device performs processing, one way is to decode through software decoding, that is, to use the CPU to complete the decoding work. However, for a single processing device, it can only process limited digital signals, such as 8 In this case, for a high-resolution display environment that can display dozens of channels, only processing 8 channels of digital video is far from meeting the needs of users. Another way is to use Dedicated hardware boards are used for decoding processing operations. In theory, as long as there are enough boards, enough digital signals can be decoded to meet the application requirements of high-resolution environments. However, due to the hardware board The data volume of the digital signal decoded by the card is very large, for example, for D1 resolution digital video, the code rate after decoding is 15MB / s), and at the same time, because the computer bus can only transmit limited signals, the decoded When the data is transmitted from the hardware board to the graphics card, it is easy to encounter a transmission bottleneck, which limits the application of digital signals in a multi-channel high-resolution display environment

Abstract

The invention discloses a system and a method for processing digital signals in a distribution type, which respectively processes different parts of the digital signal source by different processing equipment and sends the processed information to corresponding display units for displaying; images displayed on all display units are spliced as a whole display picture. As each processing equipment respectively processes a part of the signal source data only, each part is displayed by different display unit and the whole display picture with high resolution is spliced, therefore, the whole processing capability of the system is reinforced; furthermore, the requirement of high-resolution display environment is met and the display quality of high-resolution display environment is improved.
