No, more like trying to find a way for broadcasters to make a buck off digital.

They keep shooting themselves in the foot by allocating bandwidth for anything but HD, and can't figure out why HD hasn't really taken off. First it was subchannels, mobile is coming, as is data and who knows what else.

I can not understand why they won't give HD a chance.

I agree, for the $$$. I hope these next generation receivers can handle compressed content better than multipath cause it may be the next issue. HD lite OTA.

> Most popular ATSC demodulators are now:

Is the Cas-220 the same as the Cascade2 ?

http://www.crc.ca/en/html/crc/home/r...broadcast/rtnt
has test results for Linx, Zenith/LG and Samsung.

Are there any test results or reviews of the Cascade2?
Or the Zoran/Oren OR51132 ?

The CRC report states, "This Samsung ATSC 8-VSB receiver, based on Samsung Gemini chip and using an ALPS tuner, is the best DTV receiver that CRC ever tested up to now. It has very impressive multipath and C/N performances."

Most impressive, but is this combination in any existing or planned Samsung consumer unit? What's in the DTBH2650F?

You must mean the DTB-H260F, which was discussed just a few posts ago:

Cascade is the "family" name, Cas-220 is a part number of the IC.

Cas-220 = Cascade2 ( a 5th generation 8-VSB Demd.)
OR51132 = Cascade1

Since the new Samsung DTB-H260F contains the Alps TDQU3 tuner and an ATI Xilleon 240H Display Processor chip
that INCLUDES the ATSC/NTSC/QAM Demodulator, I'm going to speculate that the ATI Xilleon 240 is the "Gemini" product:

Well....
Gimini is a Samsung's ATSC Demodulator.
Samsung already integrated it into their Tuner promoting it to the DTV market as a NIM ( RF TV Tuner + Demodulator).

Samsung's Tuner operation is SEMCO. (Samsung Electro-Mechanics Co.)

Thank you.

FYI: Thompson posted (limited) specs on two ATSC_QAM_NTSC Decoder chips:
http://www.thomson.net/EN/Home/Techn...mson_4110c.htm
Claims it "meets" ATSC A/74 with +/- 40 usec multipath.

They also posted detailed performance specs for NIMs (tuner modules):
http://www.thomson.net/EN/Home/Techn...0Tuners%20NIMs
One of the three even supports the Smart Antenna option....

The sixth is back in the news:

Would be interesting to see what performance it has.
How many streams of the 50 A/74 it receives, etc...

Rick_R 07-30-2007 09:35 AM

Good to hear that they will offer a STB that incorporates this chip. I just hope that they will offer a HD version of the STB in addition to the non-HD version required by the coupon redemption.

I think CECB's killed this thread.
