Review of action items

Bin_Hu: will follow up with Kaz and JC about TPAC meeting

Review of technical use cases

<Bin_Hu> http://www.w3.org/community/tvapi/wiki/Main_Page/Technical_Use_Cases

Bin_Hu: we have 5 use case contributions
... The first use case is triggering of an interactive content overlay
... this has 6 technical requirements
... events to display/dismiss the overlay
... triggered based on various channel/timing events
... overlay has validity period
... content overlay works with different content sources

<Paul_Higgs> does "live" in the last bullet refer to over-the-air?

<Bin_Hu> yes, either over-the-air, or "live" on cable TV

cpn: cpn explains channel scan use case and integration with HTML video and audio

<Paul_Higgs> You can see a javascript object implemention of channel scanning in the OIPF Declarative Application Environment specification (section 7.13.9)

???: can we show progress indicator during channel scan?

cpn: this could be done for DVB-T as we know the range of frequencies to scan

alex: channel scan should notify when scan is complete

genelian: api should report signal strengh, to give user feedback if signal not strong enough
... detect available tuners, to notify user if a new tuner is available
... should report channel names and numbers during the scan
... uses should be able to select channels using their remote control
... allow selection of individual audio and video tracks
... events to notify programme changes
... navigation of EPG
... recording of media streams
... notify user of emergency broadcasts
... parental control
... display multiple media streams, for picture-in-picture
... link to web content relating to broadcast content

???: do we need to modify the API to support IPTV?

<Paul_Higgs> We don't normally "tune" to an IP channel

<Paul_Higgs> but a channel could carry IP content

matt: display of multiple streams may require multiple tuners

genelian: the API can cover single and multiple tuners

Paul_Higgs: picture-in-picture could be done with an IP channel and a tuner channel

Bin_Hu: this should be an application issue, based on sources provided by the API

Sung_Hei_Kim: explains ETRI use case
... URI for media sources
... display of channel and program lists
... program info in multiple languages
... links to channel services

Matt_Haynes: another use case from the BBC
... display of subtitles in broadcast video
... and audio description streams for the visually impaired

Bin_Hu: there's some overlap in these use cases
... suggest the next step is to summarise requirements from the use cases
... deadline for use case contributions is next conference call (July 8th)

<genelian> +1 summarize and de-duplicate the user cases

<scribe> ACTION: Bin_Hu will consolidate the requirements [recorded in http://www.w3.org/2014/06/10-tvapi-irc]

<scribe> ACTION: Bin_Hu will follow up with JC and Kaz re meeting at TPAC [recorded in http://www.w3.org/2014/06/10-tvapi-irc]

Bin_Hu: some people had problems dialing into today's call
... we'll try to use Zakim again next time, with IRC integration
... thanks all for your input today
