Use Case VideoBroadcast
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
- ...
Dependencies:
- other use cases, proposals or other ongoing standardization activities which this use case is dependant on or related to
Using XML to handle broadcast channel list
