• Manufacturer Part Number: lc78011e
• Description: Digital Rgb Encoder Ic For Video Cd And Cd-g
• Manufacturer: Sanyo Semiconductor Corporation

• Data input timing
5. OSD input (on-screen display data input)
• OSD timing
6. Signal format switching (NTSC, PAL, or PAL-M)
RGB input (24 bits)
Y (8 bits), CbCr (8 bits) multiplexed input
When no framing is used
The LC78011E provides an OSD signal RGB input function. Four input signals are required: the 3 bits of R, G, and B
data and the BLANK pin input signal, which is used for OSD switching.
The NPSEL and PMSEL pin (pin 31 and 32) are used to switch the signal format.
Note: The white luminance level is 162, and the black and framing luminance level is 66. (When converted from the As 8-bit data values.)
