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

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
