m16296 EBU metadata specification maintenance page have recently been updated with the audio and visual profiles as defined in our URI assets. EBU would like to receive notifications concerning updates of it. Informing EBU classification schemes is extending the list of “Genre” and “Role” originally defined in MPEG-7
m16306 This document contains short introduction about IPMP as an enabler of DRM in MPEG and the list of relevant technologies. It is agreed to produce an output document describing vision based on this input contribution and another document containing detailed descriptions about each technologies separately.

Request for Internal Liaison between SC 29 and IEC TC 9
The AVC base layer stream for SVC and MVC should be defined separately instead of a single definition (AVC video sub-bitstream that uses ‘either or’) to avoid confusion in the STD sections.
We also need to clarify the difference between MVC base view only stream from a combined stream (MVC base + 1 view - called MVC base view video sub-bitstream) and how to signal this to an MVC decoder.
Even though AVC precludes use of stream_type = 0x1F (SVC enhancement) and stream_type = 0x20 (MVC view enhancement) to enhance the same base layer stream (as the NAL unit type 14 differs between SVC and MVC) within a program (PMT or PSM), system should allow applications to use base layer specific to SVC and base layer specific to MVC within same program.
We should add text to MVC extension descriptor saying that if this is absent for stream_type = 0x1B, then this is an MVC base layer stream with no additional views.
Rx is not defined for enhancement layers in STD for MVC. This needs to be the re-assembled level based value if HRD is present or level based value from Annex A if HRD is absent.
Extending the hierarchy descriptor has made it very complex as it is used for MPEG-2, SVC and MVC. In addition, it may be difficult to check backward compatibility for all cases. The suggestion is to look at using a new hierarchy descriptor for MVC and combine the MVC extension descriptor with this new descriptor.
Re-name DRD NAL Unit to VDRD (View or Dependency Representation Delimiter) and add it for use with MVC enhancements.
Suggestion to video group to delete use of prefix NAL unit for base layer of MVC as this allows applications to add additional views to a base layer that was deployed earlier without the prefix NUT
