SONY CXD1959 POD Solution
The Sony CXD1959 POD controller resides in
the STB and delivers most of the functions that are
required to control the external POD module in a
single chip. In particular, the CXD1959 provides
the following POD interfaces required by the
OpenCable specification:
Single Slot POD (or CAM) Interface
Compliant with SCTE DVS131, NRSS-B
(SCTE IS-679 B), DAVIC v1.2 (CAO inter-
face) & DVB-CI (CENELEC EN-50221)
Integrated DES ECB and DES CBC
(DVS042) decryption cores
Integrated DVB common descrambler core
68K type host interface (asynchronous)
Current overload input (automatic POD isola-
tion) 32 concurrent PID filters with odd/even
key pairs (32 key pairs in total)
TS switch integration includes: Two parallel
TS input interfaces for connection to front-end
(FEC) and POD outputs; Parallel TS output
interface for connection to POD
Programmable Parallel/Serial TS output inter-
face for connection to transport processor
Integrated hardware hot-swap support
Control logic to support external address bus
and OOB (out-of-band) buffers
