Chinese national standardization system

• According to the STANDARDIZATION LAW OF THE
  PEOPLES REPUBLIC OF CHINA
• Standard layers and levels
• GB, industry standard, regional standard
  enterprise standard.
• Range covered
• GB security, sanitary, cross-industry
• SJ industry standards and specifications
• DB regional standards, for security and
  sanitary only
• Q/XXXX Functionalities and performance of
  specific product.
• According to the LAW OF THE PEOPLES REPUBLIC
  OF CHINA ON PRODUCT QUALITY
• Every product should follow its enterprise
  standards and the standards of the upper level.

Requirement of DTV Standardization

• Market background
• TV set manufactured 40 million/year.
• TV set installed 350 million.
• Number of manufacturers 20 enterprises, 1000
  upstream downstream operations.
• Number of TV stations 1074.
• Culture background
• TV entertainment has already become one
  of the most popular entertaining method.
• Digital TV has a brilliant future in
  China market.

Goal of Standardization

• Deliver an integrated Chinese DTV standard
  system.
• Provide technical support for DTV content
  authoring and service operation.
• Provide a scientific technical system for DTV
  terminal industrialization.
• Provide broadcast entertainment services for the
  end-users.

Highlights of DTV Standardization

• Highlights
• At the end of 2000 the special case for DTV
  standardization was proposed by the National
  Development and Reform Commission and the
  Standardization Administration of China.
• In May 2001 the National DTV Standardization
  Expert Commission was funded to draft the
  standardization requirement, software
  architecture and system as well as the ways of
  working.
• In Dec. 2001 the MII Standardization Meeting
• Initialized the standardization work for DTV
  terminal products
• Set up a standardization work team, which began
  developing the standards

Achievements of Standardization Work(I)

• Source
• Video MPEG 2
• Audio stereo MPEG2, surround audio
  format to be defined.
• Channel
• Satellite DVB-S, for transmission and
  coverage. Solution for live broadcasting?
• Cable DVB-C test broadcasting, time
  table for improvements.
• Terrestrial Transmission standard still
  under discussion, DMB-T, ADTB-T or CDTB-T?
• May finally integrate into one solutions.

10
Achievements of Standardization Work(II)

• Conditional access Standard has been worked out,
  there are still problems left for implementation.
• Data broadcasting Standardization on-going.
• Terminal standard
• Product performance and functionality standard
• Product testing standard
• Related reception standard has been
  drafted. Due to uncertainties in the
  transmission system, part of the standard will be
  delayed.

11
Achievements of Standardization Work(III)

• Middleware
• The specifications for software architecture,
  software functionalities performance and API
  has been finished. The testing suite and the
  software upgrade mechanisms are still under
  development.
• Interface
• AV?YPbPr?RGB?AV????
• HDMI?DVI???
• Interactivity interface
• Separation of STB and CA

12
Achievements of Standardization Work(IV)

• Display
• PDP, CRT, DLP, LCD and LCOS.
• Most of the standardization work has been
  finished
• Standardization of core components
• Standardization work on tuner and display.

13
Next steps for DTV Standardization

• Personal views
• DTV return channel
• IP-based DTV transmission technology
• Open software platform
• New high-efficient audio/video compression
  algorithm standard
• Source copy protection standard
• Regional content service standard

14
Existing problems of DTV Standardization

• Uncertainty of transmission system which bring
  negative effects to the standardization.
• Undefined broadcasting service models
• Build up of technical evaluation and measurement
  methods
• The corresponding IPR protection
• The corresponding compulsory product
  certification system

15
Conclusion

• The Chinese DTV standardization and
  industrialization is making rapid progress
• The current work is focused on channel and
  display equipments.
• Collaboration of various resources are required
  to build an integrated Chinese DTV standard
  system by technical RD and cooperation.
• An open environment is needed for foreign
  companies and corporations to work together and
  help local companies to achieve a win-win result.
