Use Case: Extend VIDEO tag for broadcast video support

Submitter(s): MStar Semiconductor (JC Verdié), ...

Description:

high level description/overview of the goals of the use case

Provide a unified media player interface and approach for broadcast tv on web applications

Schematic Illustration (devices involved, work flows, etc) (Optional)
Implementation Examples (e.g. JS code snippets)

   <video>
    <source="#WebTVObject" type="video/x-webtv"/>
    <track kind="broadcast_hd" src="chann1HD">
    <track kind="broadcast_sd" src="chann1SD">
    <track kind="subtitles" src="chann1subtitle">
    <div class="panel"></div>
   </video>

Need/justification:

Today, broadcast video doesn't fit in HTML5 player capabilities, leading web-based TV UI to use either proprietary or alien standards to include it such as objects with a specific mime type

Explanation of benefit to ecosystem

Broaden the range of videos supported by HTML and increase the adoption of HTML for tv ui

Why were you not able to use only existing standards to accomplish this?

There is nothing in W3C to do this, except if we consider using a plugin type object as part of existing standards for such a generic need

What might you suggest could be standardized?

Some attributes should be changed and New attributes added to the video tag to handle specific information related to broadcast video such as:

channelTuning
protocolInformation (dvb, ISDB,....)
src modified : IP address, DVB triplet,...
seek would not be available on live broadcast
...
