The HD Experience
- Roughly 53% of the viewing public has HD capable devices in their home
- 24% think they are watching HD while they have no subscription to any HD content
- Today’s HD Considerations
- Choices abound:
- format resolution – 720p, 1080i/p
- frame rates
- compression and wrapping
- audio compression and delivery
- metadata packaging, delivery, and usage
- content delivery protocols
- Metadata is going to be a part of the overall experience
- With emerging technologies:
- Super Hi-Vision (SHV, UHDTV 4320p), 3D
- HEVC/H.265, WEBM/VP8
- HDBaseT, P2PTV
- Dolby Pulse/HE-AAC
- Industry standardization
- Metadata registration, packaging, and delivery standards
- Improved picture and sound quality is a logical next step but we need to also think about the end to end viewing experience including;
- 3D video and audio content
- Mixed-mode viewing to bring interactive and immersive experiences
- Content Transportability both on-to and off-of the aircraft
