[HOME_NETWORK_TF] Requirements formulation

Hello,

I have some concerns with the top-down methodology used to document HNTF requirements. 

While the HNTF draft  requirements do not appear to be defective, they are very high-level  and it is difficult to unambiguously  determine whether the draft requirements fully map the requirements that would be generated by a bottom-up requirements review of the submitted use-cases.

I previously submitted a 1st pass at such a derivation. See 2011-07-25 [HOME_NETWORK_TF] Issue and Requirements Summary posting.

Here are a few examples of inconsistencies between the submissions.

HNTF requirements do not make a clear distinction between playable media and non-media metadata such as EPG data, Channel Lineups.

GENERIC

UPnP

ISSUE-26

User-Agent supports an application which can list EPG data provided by a home-network device

HNTF requirements do not clearly indicate that other features of home network media renderers may be controlled.

GENERIC

UPnP

ISSUE-28

User-Agent supports an application which can control presentation on home-network Media Rendering devices such as alternate audio track selection, Picture-in-Picture,  Closed Captioning, brightness, volume, etc.

HNTF requirements do not clearly describe non-media transport applications of services. This is clear in ISSUE-4 but was not adequately captured in the requirements.

GENERIC

UPnP

ISSUE-30

(not merged with ISSUE-4)

User-Agent supports an application which can control generic home-network device whose function may not be fully standardized. This may include new web applications such as E-Health, Remote Provisioning and Home Energy Management.
