Affected operating points
- Describe here as well as possible what operating points are affected and how
- In minimum, there should be a status for bitstream compatibility and output bit exactness
- For bitstream compatibility, the following levels are helpful for describing encoder
- Produced bitstream is BE compared to previous state.
- Produced bitstream is non-BE but it is fully backwards compatible for decoding. Decoded output may differ.
- Produced bitstream is non-BC. Old decoder cannot decode the produced bitstream correctly.
- For output difference, use BE or non-BE. Additionally, amount of difference can be presented.
