I read that this information are in the forum but I can't find it
So I need to Know how works the CRC Encoder to calculate de Checksum of the Nec 3540 Firmware.
I have some experience with the CRC and I know that it can have the polly you want and even theres diferentes algos for calculate de Checksum. You Can creat your own CRC Encoder.
What I want is to play with the firmware, for start I want to play with the "VIDEO_TS" string
