4 We will talk about: What about 4K? Hybrid satellite and terrestrial network Our workshop set-up for ABU 2014

5 Why 4K? Analog TV Color TV HD/Hi Vision, Digital TV 4K TV 8K TV? 1960 s 2000 s 2020 s Continuous evolution of picture quality in terms: Resolution Colors (color space, bit depth) Frame rate

6 Resolutions: Continuous evolution of resolutions Quad HD (4K) SD HD Full HD 8K 720x x x x x 4320

7 Challenging higher frame rate thanks to the 4K/UHDTV New video format is the chance to reconsider all video parameters, and the frame rate is a key one. The cinema industry is also moving toward double frame rate. (refer James Cameron works) and the EBU demonstrated very well on the last IBC show the visual gains of higher frame rate. The main reason of the visual experience improvement is due to faster camera sensors producing less panning effects and sharper images (especially at text characters or object edges). Sport video is where people can appreciate the most the advantages of higher frame rates 50p/60p comes as the new requirement for the Soccer June Note: Because the motion vectors are much reduced, encoding at double frame rate doesn t mean doubling the bitrate for the same quality. 60p 30p 24p

8 Colors: Widening of the color space ITU BT.709 (used for HD so far) ITU BT.2020 defined for and for

9 Color Depth consideration Why 10bits is required for 4K (vs 8bits): With more pixels, the gradients in the sceneries become more apparent. In order to avoid such gradients artefacts, it is necessary to go to 10bits.

10 Base-band rates and compressed rates : HD 1920x1080 4:2:2 60i (30p) = ~1.5 Gbps 4K 3840x2160 4:2:2 30p = ~6Gbps (4:2:2) & ~4.5Gbps (4:2:0) ~12 ~6 ~1.5 Gbps HD x8 x4 4K 30p 4K 60p Base-band world 4K 3840x2160 4:2:2 60p = ~12 Gbps (4:2:2) and ~9 Gbps (4:2:0) HEVC H264 HEVC H264 HEVC Compresed world Mbps H264

11 By the way,.. What connectors available for 4K (Broadcast)? 4x SDI (BNC): 4x 3G-SDI (Level A or B): SMPTE 424M 4x HD-SDI : SMPTE 292M HDMI 1.4 v: Dual HDMI 1.4v: Quad HDMI 1.4v: Display-Port 1.2v Display-Port 1.2v (Multi-stream) HDMI 2.0: 4K 4:2:210 bit 50p/60p 4K 4:2:210 bit 25p/30p 4K 4:2:210 bit 25p/30p 4K 4:2:210 bit 50p/60p 4K 4:2:210 bit 50p/60p 4K 4:2:210 bit 25p/30p 4K 4:2:210 bit 50p/60p 4K 4:2:210 bit 50p/60p ASTRODESIGN, TVLOGIC, SONY and Sharp professional displays All 4K TVs SHARP, some TOSHIBA LG, SAMSUNG, TOSHIBA, SONY PRO SHARP SHARP SONY, PANASONIC, and soon all 4K TVs

12 Modulation: 8PSK, 2/3 (22.5Mhz) Symbol rate: 18 Mbauds Bit-rate: 40Mbps ~ 58Mbps Modulation: 32K, 1/128 (8Mhz) L1 Mod: 64-QAM PLP Params: 256-QAM, 2/3, FEC-64K Bit-rate: 40Mbps Two video services encoded at 20 Mbps (19 Mbps HEVC video rate 4K 25p)
