Equipment Digitalization Conclusion

• Solved Problem
• Improve the A/V quality during whole production
  flow.
• Enhance the capability and performance of
  Equipments.
• left Problem
• working circumstance and production flow is same
  as original.
• Media material sharing still be difficulty. Still
  have to moving VTR tape etc.
• Conclusions
• Equipment digitalization have not upgraded the
  working efficiecy and benefit.

10
Focus moved to Networked

• After digitalization our focus moved to
• efficiency
• benefit
• Technical regarding emphases
• how to get media materials sharing,
  non-substance, long-distance,etc.
• Circumstance individuation, prolificacy etc.
• working flow optimized, etc.
• Low cost in buy and maintenance

11
Something should be changed

• from SDI recorded tape to data,files network
• from the content to metadata, searches, desktop
• From single use to integrated use, prophase and
  postphase use to whole working flow.
• Traditional production flow to new one. in
  exchange with Production group, on-air group, and
  Media Asset Management
• Networked Production is the efficient approach.

Networked production Broadcast in CCTV

• News Sharing System for whole CCTV
• Sports Channel Networked Production system
• Finance Channel Netwoked Production system
• Large scale postproduction Networked system
• HDTV networked production system
• The A/V library of CCTV Media Asset Management
• Harddisk broadcast system.

News Sharing System
15
WHY NEED SHARING?

• 6 channels broadcast news program.
• The news content is almost the same with a little
  difference in style.
• Each channel have their own news gathering team
  with Equipments.
• When important event happen received news
  materials, always need to make more 10 copies for
  so many channels to edit their programs.
• waste so much resources lower benefit

Files format

• High code ratio video file is MPEG-2, 25 Mbps IBP
  long GOP(15)
• Low code ratio video file is MPEG-4, 800kbps.
• Low Audio files is MP3,128kbps.

Conclusions

• After several years developing, We have built a
  whole networked and new type TV production
  management system.
• now we use network system in whole CCTV including
  production, broadcast, supervise and management.
• System design should be calculated the plan,
  system, flow and efficient.
• TV people shoul study the IT tech. new idea used
  in TV production.
• IT Tech. have been supported the main business,
  administration,and other Key useage, IT now be
  the most important role in CCTV
• How to do safe broadcast in Networked system is
  still a big problem.
