A New Standard – H.265
VCEG Main Focus Areas
Short-Term Focus:
GOALS:
Tandberg is looking at these proposals
Scalability – Temporal/Spatial/FGS
Assumed No Backward / Forward
Compatibility with earlier standards
Improved error-resilience, especially due to packet loss in IP networks
Simple ways of combining outputs ofseveral streams into a single display.
H.265 – Technology Contenders

Short-Term Focus:
- H.264 Extensions – Introducing new scalability Profiles: Spatial, Temporal, ROI, color depth, complexity (Fast Profile) etc,.
 - Trying to improve coding efficiency of certain profiles further
 
- Development of a new Standard based on the basics of compression technology: H.265
 
GOALS:
- 2x Improvement (Hard work) of Coding
 - Gain (i.e) same quality at half the bit-rate.
 - - Better Prediction (Temp Redundancy)
 - - Better coding of prediction Error
 - - Better Entropy coding
 - Minimization of Computational complexity – Encoder & Decoder

H.265 – Technology Contenders
- Introduction of Wavelets in video coding
 - New ways of distributed source video coding.
 -      Intelligent decoders & encoder – Computer Vision tools
 - Development of new transforms
 - New scalability schemes.
 - Switch to progressive (no interlaced) only tools.
 - Better Data-partitioning and Error-concealment techniques.
