Audio-visual schemes for the automotive likeness processor

Today’s very admired in the automotive enjoyable recital procedure, on advancing the scope for of video playback, motor vehicle enjoyable recital procedure is the solitary audio from the conventional procedure into a video, customer manual and integrated navigation system. Video show clearly, for instance the amount assortment from high-end 3-inch to 7 inch range. Shows that the content of knowledge usually embraces analog (such as computer disc competitor or digital broadcasting and television) and digital knowledge (such as multimedia customer interface and fascinating wallpaper). Figure 1 presenting a motor vehicle audio system. Solomon Systech Image Processor chip-SSD1922 aspects to get concurrently these needs.

Video and photograph content can be processed and SSD1922 interface through digital video screen at Delta or contrasting band sort TFT display. If the video source to get concurrently BT656/601, procedures create would be a lessening of the video decoder and more easy.

JPEG images can be stored in the SD interface SD / MMC card. SD card can be read from the JPEG file, after decoding interface through the liquid crystal display to the LCD screen

JPEG encoder block from video source (camera or DVD input) to obtain images. Ability to deal with its hardware, you can quickly display any JPEG image. SSD1922 supports dynamic JPEG format. SD memory interface will be saved in JPEG picture transmission to the SD card, micro-controller can also save any other data required. Moreover, SSD1922 operation for a variety of menus to provide two-dimensional graphics acceleration functions, such as virtual display, image display, show coverage, hardware cursor display, line draw, block transfer bit raster operation, color fill, color expansion and so on. Built-in 256KB SRAM support animation and JPEG graphics. Supporting one of the largest 640 480 delta arrangement (200K) and 480 RGB 272 stripe pixel arrangement (255K). Video input and the display resolution does not always correspond to 1:1. Adjust the size with SSD1922 features a built-in image storage to the size of SRAM scaling before. Therefore, different resolution, NTSC / PAL video source can be displayed on the LCD screen.

In short, Solomon Systech’s SSD1922 is a apt audio-visual goods in the submission of a engine vehicle of the portion, which characteristics precious and very easy submission conceive will permit us to accelerate the introduction of new products.
