Usando un normale televisore in standard PAL (il cui formato è assimilabile ad una risoluzione di 768x567 pixel) come video per il pc, dobbiamo decidere su quale risoluzione impostare la scheda grafica.
Schede grafiche dotate di uscita TV possono occuparsi della conversione della risoluzione attraverso una interpolazione, ma "interpolare" significa comprimere in uno spazio minore our pixels.
With a video card that allows us to compress the PAL signal to a resolution of 1024x768, we risk that the interpolation output makes it illegible or invisible most of the graphics are often required to interact with the application. The resolution
whose compromise between readability and compatibility with applications is that of 800x600. But moltre applications are made to run on minimum resolution of 1024x768, unfortunately also on Linux by setting lower resolutions we are with the non-scrollable dialog box whose buttons are not visible.
HD ready? No, thanks
And surely you should buy a HD ready TV
: do not recommend to see the "so-called" high-definition television to its normal, and even less if you plan to connect to your PC. Among the problems to be solved, in addition to the true image resolution on these TVs, is one of the sockets and connecting cables: to be verified if this TV is equipped with SVGA, because if connected via scart signal that passes PAL is the standard and then standard resolution. Even using the HDMI connection opens several scenarios where things often go in a very different way from what you would expect.
Keyboards and mice living in hell
The other half consists of the input devices, keyboard and mouse also by deploying wireless keyboard and wireless mouse and without the ball, expect to use in places other than a desk or in an environment like a living room poses a serious threat to family peace. The mouse forces us to a precision that could be difficult if used on special surfaces, and the keyboard is too cumbersome to keep you on your knees or beside the chair. Welcome to MythTV
After all these problems, the good news is that MythTV was developed to solve them.
The interface is designed to be visible on television type resolutions, and to use a remote control instead of keyboard and mouse.
possible to use the remote control does not mean simply finding correspondences between tasti dei telecomandi e degli acceleratori nelle applicazioni, ma fare in modo che l'applicazione sia pensata consentendone l'uso tramite telecomando. MythTV sul back endL'altro caso in cui MythTV si rivela la soluzione adatta, è se abbiamo un PC vicino alla presa dell'antenna, e desideriamo usare questa macchina come server a cui collegare gli altri pc. Questo è possibile perchè Mythtv divide le sue funzioni tra back-end (acquisizione del segnale dalla scheda video e salvataggio nel disco fisso) e front-end (visualizzazione del video), funzioni che nella configurazione più semplice possono essere eseguite sullo stesso computer che diventa un Set Top Box o un Personal Video Recorde, ma in scenari più complessi consentono to run these functions on several PCs.
