IEEE Austin COMSOC/SP Meeting

An Update on UHD Technology Evaluation

Speakers: Mr. Pierre Costa

Lead Member of Technical Staff, AT&T

Beyond being the hottest buzzword in the business, 4K or UHD is a breakthrough technology that’s shaking up the industry and rewriting the rulebook on image resolution and quality. A 4K image is four times the size of an HD image (1920 x 1080) or a remarkable 3840 x 2160! This amazing resolution creates an immersive experience where the added detail and size are similar to looking out a large window. The 4K TV new standard affects not just the world of TV and cinema, but cameras, smartphones, tablets, computer monitors and video games. Practically anything that displays images or records video will need to reckon with 4K in the coming years. But this new technology also presents some challenges, particularly in video transmission systems because of the enormous amount of data it requires. This presentation summarizes 4K work performed at ATT Labs Austin facility in the last year.

This presentation is made up of two part:

1.       Video Quality Assessment for 4K Distribution: discusses the use of 4K content encoding for distribution networks, more specifically the difference between real-time encoding and off-line encoding (non real-time)

2.       Delivering 4K content over Adaptive Bitrate (ABR) networks: this segment focuses on implantations of 4K video delivery on real (existing) networks and points to future requirements on network elements.


Pierre Costa is Lead Member of Technical Staff at AT&T Laboratories in Austin, TX where he is a research engineer in the area of video technologies. He has been an active member of several Standards bodies and has co-chaired the ATIS Network Performance and QoS subcommittee, the VSF HBRAV and QoE technical groups. He is a member of IEEE and SMPTE, and a contributor and board member of the Video Services Forum. Mr. Costa developed early ATM technology at Washington University, MO. and has been active in video quality measurement standards as well as QoS standards for close to twenty years. He received his BSEE and MSEE from the University of Texas at Austin. He owns two patents in IP-ATM protocol conversion and 27 patents in video technologies.
