Selective encryption

FNB comments
1. SVC NAL units in base layer ES: NUT 14 adopted NUT 20 not agreed at this point. Needs to work out a clear proposal when multiple video descriptors are present in one elementary stream wrt their association to NAL units.
2. Add an additional descriptor to the AVC video descriptor that also carries the information carried in the SVC descriptor: Proposal: Split current SVC descriptor into AVC part and extension adopted
3. Editorial comments: not discussed, discretion given to the editors
General remark: Clarify the use of “defined” in amendment
GNB comments

1. 
   Definition of video sub-bitstream : Not adopted. Instead the group decided to allow the NAL units that belong to temporal enhancements to be present in their own elementary stream. For that, the presence of DTS and PTS values is mandated. All NAL units that belong to the same AU have the same value of DTS and PTS.
