Problems solved by technology

However, the driver integrated circuits in the existing display modules often do not contain encoding and decoding algorithms (hardware circuits), and bridge chips are required to be responsible for encoding and decoding operations, which increases process complexity and cost

Embodiment Construction

[0032] In mobile devices, the DSC-compressed serial display data received from the MIPI interface enters as figure 1 The shown display stream compression decoding module and the display interface interaction device are processed by the interaction device (the processing flow is as follows: figure 2 Shown), obtain the MIPI data that is packaged into by the DPI data after the complete decompression, the MIPI data of this package is given to the display module of mobile equipment for displaying. In the interactive device, first, the serial display data is converted into DPI (Display Pixel Interface) data through an input decapsulation module, and the DPI data includes an input clock (pixel clock, pixel clock) and control information for decompression processing. DPI data enters the line buffer to achieve clock synchronization: the output clock generation module gives the local clock 1 with a frequency similar to the input clock to the line buffer, and the input clock of the DPI ...

Abstract

The present invention relates to the field of display processing technology, and in particular to a computer-readable storage medium and a display stream compression decoding module and display interface interaction device using the medium. The medium stores a computer program, and the computer program can be displayed by the display stream compression decoding module. Executed by a processor of the device for interacting with the display interface. The DSC standard V1.1 stipulates that bit stream compression has a fixed compression ratio, and the number of slices of a complete image can be 1, 2 or 4. The number of slices is calculated by encoding and transmitting the image parameter set, and then the clock frequency required by each module is automatically allocated, and the input and output timing of decoding is controlled, which is easy to operate. On the hardware, the data of the display serial interface is converted into the bit stream of the DSC, and the decoding algorithm in the DSC standard V1.1 of the VESA Association is implemented by hardware, which makes it simple and cheap to implement on conventional hardware.

Description

technical field [0001] The present invention relates to the field of display processing technology, and in particular to a computer-readable storage medium and a display stream compression decoding module and display interface interaction device using the medium. The medium stores a computer program, and the computer program can be displayed by the display stream compression decoding module. Executed by a processor of the device for interacting with the display interface. Background technique [0002] The Video Electronics Standards Association (VESA) established the Visually Lossless Compression Standard (DSC, Displaystream compression) group in September 2012, successfully released the first version of the DSC algorithm in April 2014, and tested more than 200,000 images, all of which are visually lossless It has become one of the industry-recognized compression standards, and the image can guarantee high compression quality. The core of the DSC standard is to provide a cl...
