: second screen use case provided from Tencent.

Dears,
we noticed that there is a specification define the use cases, requirements, examples and interfaces needed to enable web pages to display web content on secondary screens(please refer to the link:http://www.w3.org/2014/secondscreen/presentation-api/20140721/).  We provide a presentation scenario extended from the secondary screen to multi-devices and multi-screen, to show how to share and display web contents on multiscreen. This instance is used for a scenario where Presentation-API is combined with WebTiming.

Technical Background:
   There emerged an increasing number of smart devices all around us , such as smartphones, smart watch, smart wearables, smart bands, smart keychains, etc. Smart devices are configured to access  internal applicaton services combined in the smart device and multiple external services provided by different kinds of suppliers. External services are typically accessed via a remote-area network. Smart devices can handle a multiplicity of dynamic actions and interactions, governed by intelligent decision-making and organisational interaction. This may entail some forms of artificail intelligence in order to handle incomplete and non-deterministic interactions, cooperation and competition between members of organisations, richer interaction through sharing of context, sematics and goals etc.
   For an individual, may have multiple different kinds of smart devices, which are required to collaborate with each other. Among a group of people, either individually or collectively, inherently form a smart environment for sharing and interacting with each other, smart devices of the same kinds or different kinds are also required to cooperate with each other. Second screen has failed to cater to the development trend and needs, and multi-screen therefore emerges.


Specific Product Scenario:
This is a scenario based on Mobile QQ(provided by Tencent, it is a SNS product to enable multiple user to communicate with each other) and the prototype demo has been completed. Without doubt, this scenarion can be applied any other internet service for users to interact with each other.

Alice travels with her friends, Bob, Carol and David by train. Alice and her friends want to watch a movie together. However their seats are not in the same row, and the screen is too small for four people to watch together. Alice sends the video URL to the others smart devices which can access some kind of services(it is Mobile QQ in this instance) for the four people to interact with each other. After everyone receives and opens the URL, Alice will receive a notice. When the four people complete, Alice clicks the Play button and all the devices start to play the movie at the same time on their own screens. The process of watching movie and sharing their view about the movie, making some kinds of decision through the Mobile QQ, or interacting with the three other friends also takes place simultaneously, The movie is about a complex story, and they do not completely follow or understand it. And they decide to replay the previous episode. Alice rewinds the movie by 10 minutes on her device, and then all the people watch the 10-minute movie clip again. Bobs phone rings, and he has to leave for a while for the phone call. He clicks the Pause button, and movie playback is also be paused on the others' devices. 5 minutes later, Bob comes back and clicks the Play button again. The movie playback is resumed on every screen. Carol encounters a network problem, and she has to wait during movie data buffering. The others wait until Carols device continues playing the movie.

This demo can be used to show how to share online videos in a temporary discussion group and how to synchronize operation among the discussion group, such as play, pause, playback simultaneously. The sharing party can control the Play, Pause, Fast Forward, and Rewind functions on multiple devices concurrently.
