Abstract

The invention provides a display system for displaying a code stream, which comprises a decoder, a system memory, an image processing circuit, an LCD control circuit and an LCD screen, wherein the system memory comprises a display memory, the LCD control circuit comprises an FIFO buffer, the image processing circuit obtains code stream data decoded by the decode from the system memory and sends the code stream data to the FIFO buffer in the LCD control circuit, the FIFO buffer sends the data into the display memory in the system memory so that the data is used to be displayed on the LCD screen, the FIFO buffer is monitored, and information is fed back to the image processing circuit to control the write-in for the FIFO buffer, thereby the control for the code stream is realized.

Description

【Technical field】 [0001] The invention relates to a display code stream, in particular to a display system and a control method for controlling the display code stream. 【Background technique】 [0002] The application of media players in embedded products is becoming more and more extensive, and the image size and definition are also increasing, and the requirements for display systems are also getting higher and higher. [0003] figure 1 A block diagram of a system 100 in the prior art is shown. see figure 1 As shown, the display system 100 includes a decoder 110 , a system memory 120 , an image processing circuit 130 , an LCD control circuit 140 including a FIFO buffer, and an LCD display 150 . First, the decoder 110 decodes the display code stream, that is, the video data stream, and sends the decoded video data to the system memory 120, and the image processing circuit 130 acquires the decoded video data from the system memory 120 and sends the decoded video data to th...
