I think you are confusing all chip makers using the same algorithm
with
all TV makers buying their chips from the same chip maker.

Are you suggesting that all of these chip makers are reselling one
company's products?
If you would bother to understand what you referenced, NONE of these
chipsets are hi-def (1080).
And yes, H.264 is a proprietary algorithm, with only one company
providing the chipsets.
The decoding is very much *not* proprietary to one company. There
is a
consortium of companies who own patents for the MPEG-2 decoder
alone...

Once again you show you don't understand the technology, but have to
argue anyway. MPEG-2 is NOT H.264.
"The BCM3560 combines a cable/terrestrial 4/1024 QAM and 8/16-VSB
receiver, an out-of-band QPSK receiver, NTSC demodulator, DVI/HDMI
receiver, a transport processor, a digital audio processor, a
high-definition (HD) MPEG video decoder, 2D graphics processing, digital
processing of analog video and audio, analog video digitizer and DAC
functions, stereo high-fidelity audio DACs, a 250-MHz MIPS processor,
and a peripheral control unit providing a variety of television control
functions."
I am happy to admit I don't know everything about digital TV. But I do
know a ridiculous statement when I see it. "But in the U.S., the method
used is proprietary to one company. The chipsets required to decode the
signal are all produced by this company, so all TV's have similar
decoding." qualifies as a ridiculous statement. No one in the industry
would have allowed the FCC to entrench one company as the sole
manufacturer of decoder chips for digital TV.
BTW, you are right that MPEG-2 is not H.264. It's just not relevant.
They are both used for digital TV.
No, you don't know a "ridiculous statement when you see it". You have
proven multiple times you don't even know your arse from a hole in the
ground.
You really should stick with things you know something about. Maybe
eventually you can figure out what those things are.
This is why it is so much fun discussing things with you, your
professional demeanor, your courteous style and you all around good
nature. Thanks for helping me learn. 
No, you repeatedly argue about things you know nothing about. Your
claims that mp3 is not a lossy format and white noise exists in this
thread are perfect examples. And you never admit you were wrong.
Trying to educate you is like trying to teach a pig to sing. And I'm
not wasting more of my time on you.
And BTW - "pi" is not a compression. It is a representation used by
agreement. Someone who does not know the meaning of "pi" cannot discern
the number. OTOH, the person need know nothing about a compressed file
or signal other than the means required to expand it to recover the
contents.
