You're talking about movies. HDTV's all support 1080p at at least 60 Hz.
What that ATSC chart was talking about was support as in movie standards.
Since the HARDWARE supports 60Hz in 1080p HDTV's, games can be programmed for that.
No, the standard encompasses the entire system.
1. SCOPE AND DOCUMENTATION STRUCTURE
The Digital Television Standard describes the system characteristics of the U. S. advanced
television (ATV) system. The document and its normative annexes provide detailed specification
of the parameters of the system including the video encoder input scanning formats and the preprocessing
and compression parameters of the video encoder, the audio encoder input signal
format and the pre-processing and compression parameters of the audio encoder, the service
multiplex and transport layer characteristics and normative specifications, and the VSB
RF/Transmission subsystem.
The Advanced Television Systems Committee, chaired by James C. McKinney, was formed by
the member organizations of the Joint Committee on InterSociety Coordination (JCIC)1 for the
purpose of exploring the need for and, where appropriate, to coordinate development of the
documentation of Advanced Television Systems. Documentation is understood to include
voluntary technical standards, recommended practices, and engineering guidelines.
Proposed documentation may be developed by the ATSC, by member organizations of the
JCIC, or by existing standards committees. The ATSC was established recognizing that the
prompt, efficient and effective development of a coordinated set of national standards is essential
to the future development of domestic television services.
On June 5, 1992, ATSC provided information to the Federal Communications Commission
(FCC) outlining proposed industry actions to fully document the advanced television system
standard. The FCC has recognized the importance of prompt disclosure of the system technical
specifications to the mass production of advanced television system professional and consumer
equipment in a timely fashion. The FCC has further noted its appreciation of the diligence with
which the ATSC and the other groups participating in the standardization are pursuing these
matters.2
Supporting this activity, the ATSC Executive Committee requested that the T3/S1 Specialist
Group on Macro Systems Approach meet and suggest which portions of an advanced television
system broadcasting standard might require action by the FCC and which portions should be
voluntary.
Subsequently, T3/S1 held meetings and developed recommendations in two areas:
1) Principles upon which documentation of the advanced television system should be
based
2) A list of characteristics of an advanced television system that should be documented
The list tentatively identified the industry group(s) that would provide the documentation
information and the document where the information would likely appear.
The recommendations developed by the T3/S1 Specialist Group were modified by T3 to
accommodate information and knowledge about advanced television systems developed in the
period since June 1992. Some of the modifications to the recommendations ensued from the
formation of the Grand Alliance. The modified guidelines were approved at the March 31, 1994,
meeting of the T3 Technology Group on Distribution and are described in Section 4.4.
4.1 Advisory Committee on Advanced Television Service (ACATS)
A Petition for Notice of Inquiry was filed with the FCC on February 21, 1987, by 58
broadcasting organizations and companies requesting that the Commission initiate a proceeding
to explore the issues arising from the introduction of advanced television technologies and their
possible impact on the television broadcasting service. At that time, it was generally believed
that high-definition television (HDTV) could not be broadcast using 6 MHz terrestrial
broadcasting channels. The broadcasting organizations were concerned that alternative media
would be able to deliver HDTV to the viewing public, placing terrestrial broadcasting at a severe
disadvantage.
The FCC agreed that this was a subject of utmost importance and initiated a proceeding (MM
Docket No. 87-268) to consider the technical and public policy issues of advanced television
systems. The Advisory Committee on Advanced Television Service was empaneled by the
Federal Communications Commission in 1987, with Richard E. Wiley as chairman, to develop
information that would assist the FCC in establishing an advanced television standard for the
United States. The objective given to the Advisory Committee in its Charter by the FCC was:
The Committee will advise the Federal Communications
Commission on the facts and circumstances regarding advanced
television systems for Commission consideration of technical and
public policy issues. In the event that the Commission decides that
adoption of some form of advanced broadcast television is in the
public interest, the Committee would also recommend policies,
standards, and regulations that would facilitate the orderly and
timely introduction of advanced television services in the United
States.
The Advisory Committee established a series of subgroups to study the various issues
concerning services, technical parameters, and testing mechanisms required to establish an
advanced television system standard. The Advisory Committee also established a system
evaluation, test, and analysis process that began with over twenty proposed systems, reducing
them to four final systems for consideration.
4.2 Digital HDTV Grand Alliance (Grand Alliance)
On May 24, 1993, the three groups that had developed the four final digital systems agreed to
produce a single, best-of-the best system to propose as the standard. The three groups (AT&T
and Zenith Electronics Corporation; General Instrument Corporation and the Massachusetts
Institute of Technology; and Philips Consumer Electronics, Thomson Consumer Electronics, and
the David Sarnoff Research Center) have been working together as the Digital HDTV Grand
Alliance. The system described in this Standard is based on the Digital HDTV Grand Alliance
proposal to the Advisory Committee.
4.3 Organization for Documenting the Digital Television Standard
The ATSC Executive Committee assigned the work of documenting the advanced television
system standards to T3 specialist groups, dividing the work into five areas of interest:
Video, including input signal format and source coding
Audio, including input signal format and source coding
Transport, including data multiplex and channel coding
RF/Transmission, including the modulation subsystem
Receiver characteristics
The standards document is explicit, it covers all components, and it covers all HDTV equipment in North America. Can you cite any evidence that is contrary?
