hi,
at first sorry for a probably bad english!
for a few month i have bought a set-top-box from samsung on ebay, exatly
a Sasmung Media Receiver SMT 7020S.
this box has a dvb-s tuner and can also be used for vod from t-online
(the box ist printed with Ready for T-Online Vision).
here are the specs:
Mobile Intel(R) Celeron(TM) CPU 733MHz
128MB RAM
Intel Corporation 82815 CGC [Chipset Graphics Controller]
Intel Corporation 82801BA/BAM AC'97
Intel Corporation 82801BA IDE U100
VIA Technologies, Inc. USB 2.0
Intel Corporation 82801BA/BAM/CA/CAM Ethernet Controller
Conexant CX23880/1/2/3 PCI Video and Audio Decoder
Conexant CX23880/1/2/3 PCI Video and Audio Decoder [MPEG Port]
all chips are placed on one board.
the box has no vga or dvi output, only scart is available.
so the i815 and maybe the cx88 are connect to a focus fs454 (over DVO
output, see http://216.103.204.9/corporate/pr_new/170903_intel.htm).
the focus fs454 chip is placed on the underside of the board and is
probably connected via i2c to the i801 and can switch beetween the intel
and conexant.
or does the conexant write direkt to the buffer from the i815?
pictures are available from
http://smue.org/gallery/v/vdr/samsung_smt7020s, an i have send some self
made pics to Gunther Mayer (the email is from
http://www.linuxtv.org/v4lwiki/index.php/How_to_add_support_for_a_new_card)
the box runs original wince from a 32mb dom, but i will see linux
running on this box
this is the output from lspci -vv

additional there are a STV6412A, a ISL6421AER, an ATMEL042 24C02N and
the tuner TDQF-S001F.
there is also a winbond w83627hf.
can anyone please point me to the right way, or can help to get this box
work?
on the backside is a 6-pin connector called console near the tuner. ???
best regards
MichaeL
