ALGORITHMS AND FUNCTIONALITIES SUPPORTED WITH EACH PROFILE

Profile Algorithms
HIGH Supports all functionality provided by the Spatial Scalable Profile plus the provision to support
3 layers with the SNR and Spatial scalable
coding modes
4:2:2 YUV-representation for improved
quality requirements
SPATIAL Scalable Supports all functionality provided by the SNR Scalable Profile plus an algorithm for
Spatial scalable coding (2 layers allowed)
4:0:0 YUV-representation
SNR Scalable Supports all functionality provided by the MAIN Profile plus an algorithm for
SNR scalable coding (2 layers allowed)
4:2:0 YUV-representation
MAIN Non-scalable coding algorithm supporting functionality for:
coding interlaced video
random access
B-picture prediction modes
4:2:0 YUV-representation
SIMPLE Incudes all functionality provided by the MAIN Profile but
does not support B-picture prediction
modes
4:2:0 YUV-representation
