M15614: CD proposal of LASeR in IPTV. This contribution analysis the open issues listed in the current WD. Dispositions to proposed items are as follows:
attribute vs. element : Accepted to define new attributes. There was understanding that adding new attribute might violate the extension rule defined by W3C. However, this rule doesn’t seem to be generally obeyed. Therefore, it would be better to take technically preferable solution.
attributes to describe adaptation criteria : accepted to define only minimum values for screen size and available memory. It was concerned that it’s not easy to measure and apply CPU power and remaining battery in a meaningful way.
display size event for dynamic adaptation : accepted to include.
EnhancedSceneIndicator in the LASeR header : accepted
priority: Accepted in principal. Detailed syntax and semantics should clearly mention the selection criteria for the case of combination of this priority and other attributes.
M15622: Proposal for the Presentation of Structured Information. Was reviewed in detail in the AHG (see AHG report). Taken as a basis to produce related specification.
M15649: Timed Representation of Metadata for the Presentation of Structured Information (PSI). Was reviewed in detail in the AHG (see AHG report). Already a standard of MPEG. Can be used in a more general framework where server side standardization is usefull.
Technical Work in Progress.
