3 What is 8K video UHDTV (Ultra High Defini on TeleVision) 4K : 3840 x 2160 pixels (4 mes as many pixels as HDTV) 8K : 7680 x 4320 pixels (16 mes as many pixels as HDTV) Proposed by NHK Science and Technology Research Laboratories (NHK Giken) Defined and approved by ITU- R and SMPTE pixels 4320 pixels HDTV 4K 8K (c) Copyright: Nippon Telegraph and Telephone,

4 Mo va on Demand of handling high- resolu on video increases Handling: Send, receive, store, playback, etc ex. Sports events are shot and delivered to public viewing as UHDTV (4K, 8K) Olympic games, World cups, Major league baseball games, Football, etc Transmi ed 8K video of World Cup games from Brasil to Tokyo and other ci es in K video equipment is now available in Japan 8K camera: AH (Astrodesign, Inc.) 8K recorder: HR C (Astrodesign, Inc.) 8K projector: DLA- VS4800 (JVC Kenwood Corp.) 8K glass- free 3D LCD monitor: Prototype (Sharp Corp.)

Sends and receives mul ple uncompressed 4K video streams in real me through IP network Accepts and transfers video files with FTP protocol Supplied by NTT- IT Corp. as commercial product Smallest system, which can be configured with one PC, can record and play back up to high- resolu on video Please refer: h p:// ipvs/english/product/p01/index.html (c) Copyright: Nippon Telegraph and Telephone,

11 Synchroniza on Why synchroniza on is required? 8K monitor requires 16 HD- SDI signals which have completely same frequency and same phase each other 8K monitor does not have enough buffer to absorb ji er or difference of frequency of input HD- SDI signals XMS system Smallest system is highly cost- effec ve, but it can not play back 8K (up to per unit XMS records 8K video as independent 16 HD video streams for scalability reason It is PC- based system which has low accuracy quartz. So, each XMS system maybe work with different clock QG- 70 High accuracy quartz Four QG- 70s are required for 8K- video transmission Maybe output HD- SDI signals different phase each QG- 70 Mul ple XMSs and QG- 70s must be introduced for 8K video transmission system Synchroniza on is required in case of play back 8K video from XMS systems We have developed and implemented synchroniza on mechanism shown in following slides for XMS and QG- 70 to transmit UHDTV (c) Copyright: Nippon Telegraph and Telephone,

12 Synchroniza on (Cont.) Frequency and phase synchroniza on Introduce reference signals into all receiver QG- 70s to synchronize frequency and phase between all output HD- SDI signals Each receiver QG- 70 sends synchroniza on packets to sender XMS system to synchronize frequency between receiver and sender Sync signal generator Adjust frequency and phase Synchroniza on packets Adjust frequency QG- 70 (Receiver) XMS (Sender) 8K monitor HD- SDI x 4 (c) Copyright: Nippon Telegraph and Telephone,

Frame number synchroniza on XMS records 16 fragments of same 8K- video frame with same ID Select one QG- 70 among receivers as Master Master QG- 70 broadcast the ID with which it currently play back frame to all other receiver We can get complete synchroniza on at receiver side by using above methods And also get complete synchroniza on using mul ple 10- Gbps networks with different delay because of this scalable method ID=1 ID=1 Report current ID QG- 70 (Receiver) ID=1 ID=2 ID=3 ID=1 ID=2 ID=3 ID=1 Relay current ID ID=1 ID=2 ID=3 (c) Copyright: Nippon Telegraph and Telephone,
