YGV619
AVDP6
Advanced Video Display Processor 6
ν Outline
YGV619 (AVDP6) is a VDP (Video Display Processor) adopting OSD display control system that is best
suited to the data broadcasting. The digital image interface of this device for connection with MPEG decoder has
been improved. The use of this device allows screen composition that is suited to mobile information terminals,
car navigation system, etc. Scan timing conforming to the display standard of digital TVs can be made.
Two built-in PLL circuits allows to realize superimposition of external image signal on original one, and to
produce clock best suited to SDRAM that is adopted as external video memory.
ν Features
Display planes: External digital image is overlaid with OSD images composed of regions.
Up to four planes, which are individually composed of backdrop plane (plane on which external images are inputted)
+ region, are available.
OSD image format:
8bit/dot palette mode, and 16bit RGB or YCrCb format can be selected.
YCrCb conforms to the conversion method of ITU601.
Color palette (256 colors in 16777 k colors) can be specified by region.
Digital image input format:
· 18bit R6G6B6
(Max. dot clock frequency: 80 MHz)
· 16bit YCrCb422 (ITU601) (Max. dot clock frequency: 80 MHz)
· 8bit YCrCb422
(Dot clock frequency 27 MHz)
Digital image output format:
· R6G6B6 + 2bit AT
· 18bit YCrCb444 + 2bit AT
· 16bit YCrCb422 (ITU601) + 2bit AT
· 8bit YCrCb422 + 2bit AT + 7bit α blending coefficient
Max. OSD resolution: 960 dots × 1080 lines
(However, max. resolution of overlaid external image is 1920 ×1080 lines)
Applicable digital TV image format:
· 525i
· 525p
· 1125i
Video capture function:
· Draws external video input on the frame memory in real time.
· Can convert resolution.
· Provided with progressive scanning conversion
