DeJaVu....
In Nov 2005, Zoran and Thompson announced A/74 Compliance:
http://www.zoran.com/Zoran-and-Thomson-Announce-Low
Thomson DTT768XX NIM spec sheet (dtg Oct2006 and perhaps earlier)
claimed "full compliance" to A/74.
Earlier, in Dec 2004, ATI claimed they met ATSC A/74 Guidelines:
"performance parameters for receiver sensitivity, multiple signal
overload, phase noise, selectivity, and multipath distortion."
Latest article probably means Zoran is first ATSC Receiver
TESTED BY CRC that passed those sub-set of A/74 tests actually
performed by CRC.
Of interest would be how many Field Ensembles "passed", compared
to batting about 0.5 for the "best" HDTVs tested in
FCC OET TR-05-1017:

BTW: CRC did not conduct this test in the publicly posted tests.

The Zoran processors they mention, however, are combined demods and
MPEG-2 decoders. So whatever A/74 recommendations they exceed must have
more to do with things like echo tolerance, and less to do with IM3
distortion or selectivity.

Zoran's ATSC Digital Television Receiver Is First to Exceed A/74
Requirement For Digital Broadcast Transition
Compliance Tests Performed by Communications Research Centre Canada
Sunnyvale, Calif. - July 16, 2007 - Zoran Corporation (Nasdaq: ZRAN)
announced that its Cascade vestigial sideband (VSB) receiver technology,
is the first to exceed A/74 requirements and to comply with the Advanced
Television Systems Committee, ATSC Recommended Practice: Receiver
Performance Guidelines, according to a recent Laboratory Test Report
issued by the Communication Research Centre Canada (CRC), an industry
recognized independent testing laboratory.
These guidelines seek to determine a receiver's capability to receive
DTV signals under conditions expected to be found in various free-to-air
reception environments such as densely populated urban areas, where it
is more difficult to deliver clear reception due to broadcast
reflections off buildings and vehicles.
"The overall receiver performance is above average of the other ATSC
receivers tested in the last years at CRC. It is the first receiver to
achieve or exceed all the A/74 requirements . . . ," states the
Executive Summary of the Laboratory Evaluation of a VSB Television
Receiver for Terrestrial Broadcasting, published May 14, 2007 by
Communications Research Centre Canada.
"The A/74 Recommended Guidelines are the industry's unbiased objective
criteria for ATSC receiver performance. We are pleased that Zoran's
technology is the first to achieve and exceed these important
performance requirements that will become standard as the U.S. converts
to digital television broadcasts in 2009. Meanwhile, we are enabling our
customers to deliver ATSC compliant products now so that consumers will
have affordable choices during the transition," said Ram Ofir, senior
vice president, general manager Zoran's Home Entertainment division.
Zoran's Cascade VSB receiver technology is integrated into its
SupraHD(r) 740 and SupraHD(r) 760 DTV processors as well as additional
SupraHD(r) processors that will be introduced later this year.
Zoran's SupraHD(r) 740 processor powers its analog-to-digital converter
box solution, which includes in-house, royalty-free ATSC middleware, a
decoder, a complete ATSC demodulator, efficient single-memory system
design, and application engineering that assists manufacturers in
bringing new products quickly to market.
Zoran's SupraHD(r) 760 processor integrates all the components required
to replace existing multi-chip TV solutions. It supports full ATSC and
NTSC functionality required for digital and analog TV as well as high
quality video scalar capabilities previously reserved for high-end,
multi-chip HDTV solutions. It is capable of driving various types of LCD
panels up to 1440 x 900 resolutions.
