Use Case: Home Network Enabled User-Agent - Network Device Controller

Submitter(s): Samsung Electronics (Russell Berkoff)

Description:

Need/justification:

  • Existing Home Network interfaces do not (by scope/tradition) standardize user interface control. However, the combination of HTML markup and Javascript allow both access to Home Network devices functions and access to very capable user interface resources.
  • Why were you not able to use only existing standards to accomplish this?
    • HTML User-Agents do not provided the abstractions necessary for Javascript to issue discover and issue commands to home network devices.
    • Basic access methods to home network devices need to be standardized so that developers can implement pages to control Home Network devices using Javascript/HTML.
  • What might you suggest could be standardized?
    • Provide generic access methods to enable a User-Agent to discover and command home network devices.
    • Provide extensions to HTML5 <video>, <audio> elements to allow HTML5 to comply with Home Network Media Transport Requirements (mainly DLNA specific headers). Also, provide backward-compatible extensions to previous HTML versions to support similar functionality (presumably as browser-plugins).
    • Provide access and privacy controls for untrusted pages accessing home network devices.
    • Allow pages to control future Home Network device classes where the comand sets are not currently known.
    • Allow pages to discover functional differences (optional functionality) that may be implemented in some but not all Home Network ecosystem devices.

Scenarios

  • The User-Agent commands future home network device classes. For example:
    • Control of home-automation devices such as window shades or (HVAC) room temperature.
    • Control and monitoring of home-energy standards compliant devices (energy usage, time-of-day scheduling).
    • Control of E-Health and Fitness devices.
    • Control of Device Management devices (provisioning, firmware upgrades, etc).

Dependencies:

  • This use-case provides the basic framework for generic access to home network devices. It is "agnostic" towards the underlying functionality of the devices being controlled.
