PCI video broadcast decoder
SYMBOL
can be selected:
a) Digital Video Port (VP): output only; in 8-bit and 16-bit formats, such as VMI, DMSD (ITU-R BT.601); zoom-video,
b) Transport Stream (TS) capture input: from the peripheral DTV/DVB channel decoder; synchronized by Start Of
c) Digitized raw DTV/DVB samples stream output: from internal ADCs; to feed the peripheral DTV/DVB channel
d) GPIO: as default (no other function selected); static (no clock); read and write from or to individually selectable
e) Peripheral interrupt (INT) input: enabled by interrupt enable register; routed to PCI interrupt (INT_A).
