Agenda

• Why HEVC and 4K together?• UHD/4K TV: Status and Next Steps• HEVC for HDTV and TV Everywhere


Why HEVC and 4K Together?


Why HEVC and 4K Together?6

• HDTV and H.264/AVC• H.264/AVC (Advanced Video Coding): defined in the 2000s for

HDTV compression• HDTV 1080i requires around 8Mbps

• UltraHD/4K• x8 more pixels than HDTV• Potentially 60+Mbps with H.264/AVC• New compression required: H.265/HEVC is here and is a

MUST for UltraHD/4K


Is UHD/4K the only role for HEVC?

• NO!• HEVC:

• Halves bandwith compared to H.264/AVC for all formats• Halves transmission costs

• HEVC in meant also for:• HDTV Broadcast• HDTV streaming on IP networks / telco networks


4K TV: Status and Next Steps


UHD/4K: Larger picture

9

• UHD: More pixels for more details HDTV: 1920 x 1080 UHD/4K: 3840 x 2160

• Wider viewing angle for an immersive experience Viewing angle: 60°instead of 30°

• But is this enough to create a market shift?


UHD: improved motion

• The larger the screen, the more pictures you need!

• 30 frames per second (fps) is not enough• Shutter time when shooting movement is critical

• 60 fps is a minimum already in HDTV• Up to 120fps is considered for future systems

UHD: Better Colors

• Current TV color system (BT 709) was born in 1993 and was meant for CRTs (Cathodic Ray Tubes)

• New TV color space (BT2020) has been defined for UHD and flat displays

UHD – Status15

• UHD is ready for deployment• Video: 4Kp60 10bits• Full support of BT2020 and High Dynamic Range• Audio: AAC, Dolby AC3, Dolby AC4 (5.1), DTS 11.1

• Full interoperability with Set-top-boxes and UHD displays


UHD – Status16

• Primary distribution• 4kp60 @ 100Mbps for primary distribution

• Broadcast• 4kp60 HEVC-HEVC transcoding @ 20-30Mbps for broadcast

HEVC for HDTV and TV Everywhere


HEVC – other applications

• HEVC for HDTV broadcast• Reduces transmission costs by 2• Full support of 720p60 and 1080i30• Target rate: 4 to 5Mbps

• HEVC for HDTV streaming• 720p60 around 1Mbps for small screens (smartphones)• 720p60 around 3Mbps for larger screens (Connected TV)• Transmission protocol: MPEG DASH


HEVC streaming – Benefits

• Benefits of streaming• Unicast: one-to-one dstribution• Light structure for deployment• Allows for new applications

• Dynamic ad insertion• Network-side ad insertion• Player side ad insertion

• Targeted watermark• Uniquely identified leaked content per

user• No player integration required

• TV anytime• Personalized time-shifted playlists

• Analytics• Audience measurement• CPM calculation


HEVC streaming – system architecture


HEVC streaming – status

• First HEVC operational deployment in 2014• 4G Mobile network in China

• HDTV and 4K streaming• Launch of services to connected TVs, or IP boxes• MPEG-DASH transport


Conclusion

• HEVC end-to-end system are ready and have proven performance in operation• For HDTV and UHD/4K• For Broadcast and Streaming

• HEVC encoder implementation confirm that rate reduction is already close to 50%

• The market is ready for the move
