- 9. GoogleTV: Pros • Part of the Android-family. • Deploying apps is easy™ (via Play Store) • Re-use most of your existing Android code
- 10. GoogleTV: Cons • Does not evolve as fast as mainline Android • Not many devices sold (500,000 - 1,000,000) • Late start in the European Union (2012)
- 11. Help me Android. You're my only hope
- 12. Part II: ChromeCast aka Google Cast Devices
- 13. ChromeCast: Hardware • Model Number: H2G2-42 • It’s not based on ChromeOS • It’s based on Android and Chromium • It’s not going to kill GoogleTV http://www.ifixit.com/Teardown/Chromecast+Teardown/16069
- 14. ChromeCast: Pros • Very cheap hardware (35$) • Very easy to use (My Grandma can do it™) • Web Developers can easily write „Receiver“-Apps • Simple Protocol Stack
- 15. ChromeCast: How does it work?
- 16. ChromeCast: Cons • Google Cast SDK is still a Developer Preview (read: things will break, things will change) • You have to manually whitelist all your apps with Google • It’s not officially released outside the U.S. Things have been broken. But the SDK is stable now.
- 17. WebTech UDP ChromeCast: Protocol Stack • SSDP (Simple Service Discovery Protocol) • DIAL (DIscovery And Launch) • RAMP (Remote Application Media Protocol) • HTML5 & JS (You know that this is) • WebSockets (Bi-directional communication Browser<>WebApp) • WebRTC (Web Real Time Communication)
- 18. TCP WebTech UDP ChromeCast: New Protocol • mDNS (Multicast Domain Name System, aka Bonjour) • Protobuf over TLS Sockets • RAMP (Remote Application Media Protocol) • HTML5 & JS (You know that this is) • WebSockets (Bi-directional communication Browser<>WebApp) • WebRTC (Web Real Time Communication, ex. Screen Mirroring)
- 19. ChromeCast: How it works! 1. Advertises ChromeCast using mDNS (UDP Broadcast) ! 2. Discovers Endpoints using mDNS ! ! 3. Requests App and opens TLS Socket connection ! ! ! 4. CC fetches HTML5 based 1st Screen App (opens WebSocket)
- 20. ChromeCast: How it works! II! ! ! ! 5. Sends request to play media ! ! ! ! ! 6. HTML5 app receives media request (WebSocket) starts fetching content. ! ! ! ! ! ! 7. Media is downloaded/streamed by ChromeCast device
- 21. ChromeCast: Sender App • Cast SDK available for • You need to pay $5 to create an account on the Google Cast Developer Console
- 22. ChromeCast is not just for „streaming“ video content.
- 23. It’s a remote controllable Chrome Browser running on your TV.
- 24. Use Cases: PhotoCast
- 25. Use Cases: CastPad
- 26. Part III: ChromeCast without ChromeCast* * includes shameless plug
- 27. CheapCast all the Droids • Is an app that emulates a ChromeCast (or Google Cast) device on almost any Android Device • Implements DIAL, RAMP/WS Proxy-ing • Does not care if your id is whitelisted or not. • Written by me
- 28. CheapCast: Components WebView SSDP Service DIAL REST WS ChromeCast API Ext 1st Screen Output Receiver App Sender App
- 29. CheapCast: Use Cases • Start developing ChromeCast apps without owning an actual ChromeCast Device • Turn one of your old Android-devices into a ChromeCast Dongle (connect via MHL<->HDMI) • Cast content from your Android Smartphone to your Android Tablet just for the hell of it.
- 30. CheapCast: OpenSource https://github.com/mauimauer/cheapcast Licensed under the Apache 2.0 License Made possibleby Chromium Totally useless right now! But it mightcome back…

- 32. Just Rumours?Yes! But Google Cast ist not going away soon.
- 33. Q&A Follow me on G+
- 34. First one to scan this QRCode to find out the Codeword wins.
- 35. Thanks. Teşekkürler.
