The HD-SDI CRC’s – What a story !
(French and English document)
It is well known, that in HD-SDI, each line has its own dual CRC control packet in order to check separately the luminance and the chrominance of a signal. It is less known how it works really. This note is giving the basic knowledge in order to understand the process involved in this technology maintaining the integrity of the data in a digital path. At the same time, it will explain a bit more the interest of the data display available in oscilloscopes.
