5 Live Video for Ski World Cup Falun 2015 Live Video Ca che Ca che s Ca che 3G/LTE Goal with the project: Offer a live video streaming Android application for the FIS Nordic World Ski Championships 2015 in Falun as part of the Virtual Arena, see Live video from any Android client should be distributed using Erlang s. For information on, see Two key objectives are to take an existing prototype and evolve it so that it can: Be distributed to real users via an Android market educe the delay in the streaming service to become near realtime Uppsala/Falun Page 5

6 How the Live streaming service is used ecording a video User starts the recording app and selects the publish option. The application will then publish the stream object with location and thumbnail. The user can optionally add human readable name and/or description of object to the metadata of the object. Live Video C Playing a streamed video User needs to get the name of the desired stream. Possible ways of getting the name includes: Clicking on stream object (e.g. a thumbnail or location on map) in event browser (see next slide) Clicking on name/thumbnail (from regular web page or from the Virtual Arena Scanning a Q code on a poster/sign or on a screen, e.g. a Jumbotron C a c h e a c h e s C a c h e 3G/LTE Uppsala/Falun Page 6

Data sources As an additional feature the virtual arena could potentially connect to the live streaming service as a user of the service (seen from the live streaming service perspective). The virtual arena can then treat these streams as any other content stream. This would require that there is a clear interface to the virtual arena (e.g. video format, GPS coordinates, ) which we can deliver our streams to. There should not need to be any modifications done to the virtual arena for this. Uppsala/Falun Page 9

This needs to be done in a way that it does not interfere with any existing WiFi service. WiFi access points are combined with s. (Either the APs need to be able to connect to two different backhaul s or the s, which are transparent to IP traffic, needs to be powerful enough to not become bottlenecks.) The live streams can thus be served in the local WiFi by nearby users without causing traffic on backhaul links. The clients in the Androids connect directly to these s. equirements on the NS that can resolve IO name to streaming locator DHCP for connecting clients to

13 Event Browser for User Generated Content In addition to official content from the event organizer, users will also generate content (videos/photos/etc) to share with other users. It is important to have an intuitive and user friendly way for the user to find interesting content in the to view. Event Browser When a user generates and publishes content, it is tagged with a timestamp and location where it was created (Location can use GPS or other localization technology) The Event Browser provides a graphical representation of all content in the system through a map of the event area A time slider allows the user to browse through the recent history of the event and see on the map when and where content has been published There is also the option to set triggers so that the system notifies the user when new content that was published nearby is available Design choices: Show all data in the browser, or only locally available (or differentiate in the view so the user knows expected delay) How to share data between users?
