SD to Analog Video Encoder Modules (PT-ENC-OB)
Operation
The
PT-ENC-OB
is a SD-to-analog video encoder output module that converts a block of eight serial SD
digital signals to composite NTSC or PAL video signals.
The
PT-ENC-OB
module accepts 32 serial digital (SD) video signals from the crosspoint module, which
are presented to four FPGA-based deserializer chips. Within each of the deserializer chips are two 4×1
multiplexers that switch the signals to the receiver blocks.
The two receiver blocks within each of the deserializer chips perform the functions of extracting and
locking all conversion functions to the bit-serial clock. To do this they:
Use the internal and external PLL circuitry to descramble the SMPTE non-return to zero (NRZI) SDI
stream
Find the "x3FF" start of active video/end of active video (EAV / SAV) frame boundaries
