CineCast HD Version 2.6 Installation and User Manual
DECODER Command (45h)
Example
To change the Chroma Phase (Register 0x5A) to a value 0x2C:
• Decoder Command 0x0029 with 32-bits data = 0x0000065A (write to 0x5A,
device = 0x00, operation = write).
• Decoder Command 0x002A with 32-bits data = 0x0000002C (write value
0x2C to register 0x5A).
Default Video Parameters — CineCast HD
Serial EEPROM Access
The CineCast HD includes an Atmel AT24C02 (256 x 8) Serial EEPROM. Ac-
cess to this serial EEPROM is reserved for factory use only.
To write a value to Serial EEPROM, write value 0xAA to address 0x55:
• Decoder Command 0x0029 with 32-bits data = 0x00002655 (write address
0x55)
• Decoder Command 0x002A with 32-bits data = 0x000000AA (write value
0xAA to register 0x55).
To read a value from Serial EEPROM:
• Decoder Command 0x0029 with 32-bits data = 0x00002701 (read address
0x01)
The read data is returned in Mode Page 0x30 in the “Decoded Frame Number” (in
the lower byte, byte 11) for the first access to mode page 0x30 after an IIC Read
command.
002B Error Mask:
Used to enable/disable error checking for MPEG stream
decoder errors, audio/video channel buffer errors, and loss of genlock errors.
By default, all these errors are masked (disabled). The 32-bits of data contained
in the Error Mask are as follows:
