Use Cases
- TOM has installed a command line system. He does have a tv connected to his computer. He presses a define key that launches a LMC gui on his TV. He browses his media library. using a joystick connected to his command line system and then launch a webtv.
- Nadia takes her remote controller, press a define key that launches a LMC gui on her computer’ screen. She navigates through her media database and launch a film.
- Math is blind. He just came home from work. He says a defined keyword and gets a vocal answer.
- Math : LMC
- computer : LMC activated
- Math : Play Beethoven … all
- Computer : Any order ?
- Math : Random
- Computer : Starting
The music starts playing with the default sound volume.
30 seconds after, after no recognized vocal input, computer listener is deactivated. Math has set an option so that the computer tells him.
- Computer : deactivating listener
Summary
- What’s the differences between those use case ?
| Comparison Points | TOM | NADIA | MATH |
|---|---|---|---|
| UI | Graphical Output on TV | GUI over Xorg | Vocal UI |
| Controller | Joystick connected to the computer | Remote controller on the computer | Vocal controller |
| Player | WebTV player | Video Player | Music Player |
| Core functionalities | Media library, research capacity, player selection, plugins inter communication | ||
- Should Media Center programmers be competent in all those domains ?

- Zooming In on Linux MCE & Pluto
LinuxMCE (based on Pluto Open Source code) is seemingly the actual best solution that fits the previous Use Cases without the developers having to do all the functionalities. Basically, actually the developper are connectors developpers (which means they develop wrappers for external stuff like Xine, Asterisk, MythTV) and integrators (they zrite stuff to have a PnP system). So their approach is a plugin approach, and the core of LinucMCE is a bus to help plugins to communicate via a DCE system. The only thing that I think is lacking is , the core system seems to be only doing a communication job and I wished it was also doing the Media Library management. I didn’t also see in that project the UI as a plugin, which should really be cool to offer a larger panel of fuctionality and satisfy more people.

- Defining plugins categories
- Defining the specs of the LMC’s core.
