□ Decoder Function
Three 10-bit ADCs
Two video decoders
Analog video input simultaneous decoding up to 2 channels
Decodable combinations:
Composite Video × 2
Composite Video + S video
Composite Video + Component Video
Multiple analog video sources switching function
Brightness correction function
Tone correction function
□ Video Memory Interface
Selectable video memory (64Mbit, 128Mbit, or 256Mbit)
Video inputs that can be captured:
Composite Video, S Video, Component Video, Analog RGB,
ITU-R BT.656, and Digital RGB
(However, as for Digital RGB, dot clock must be lower than 30MHz and the size must be smaller
than 720×480 with the progressive scan performed.)
Capture (only Y component) for recognizing images
Area designation for capturing video
Captured video error control function
Interlace function
Automatic frame period conversion function
□ Rendering Function
Rendering function with rendering commands
Three types of commands: LINE, FILL, and COPY
Built-in Command FIFO (next rendering command can be issued before the end of the previous
command.
Format conversion function
α-blending function at the rendering (α value can be designated in dot.)
Color Mask function
Antialias function at LINE command
□ Display Function
Simultaneous display up to 5 planes: Backdrop plane, two OSD planes, and two capture planes
Display priority control function
Window function (only capture plane)
Transparent dot designation
α-blending function
Flicker cancel function
Captured video correction function: Scaling, distortion correction, inclination correction (only capture
plane)
Resolution conversion function (only capture plane)
PAL → NTSC conversion function
NTSC → PAL conversion function
Interlace → progressive conversion function
□ CRT Control Function
Supports both interlace scan and progressive scan
Supports both NTSC and PAL
Supports QVGA to XGA
Display timing setting in dots and lines
