GEFEN HDMI Switcher...Help Please

[chr0m]

Innanzi tutto mi scuso preventivamente se per caso ho postato nel topic sbagliato... comunque la mia domanda (da totale ignorante in materia) è la seguente:
Qualcuno potrebbe gentilmente spiegarmi, nella maniera + semplice possibile, le differenze tra i seguenti 2 prodotti
- http://www.gefen.com/kvm/dproduct.jsp?prod_id=4560
- http://www.gefen.com/kvm/dproduct.jsp?prod_id=5261
Visto che la differenza di prezzo è notevole vorrei capire a cosa è dovuta e perchè dovrei sceglirere l'uno piuttosto che l'altro a fronte, ripeto, di un esborso sensibilmente maggiore.
Grazie in anticipo per l'assistenza

discussione spostata.

Hai provato a leggere poi attentamente le specifiche?

Ciao

[chr0m]

Ti ringrazio per la considerazione del mio grado di intelligenza..Come ho scritto sono totalmente incompetente in materia ciò implica che non sono esattamente in grado di valutare le differenze nelle specifiche (che mi sembrano pressochè identiche..a leggere ci arrivo ancora oltre non garantisco). Per cui gradirei che qualcuno mi aiutasse se non è di troppo disturbo abbassarsi al mio livello. Grazie

Access up to Four Sources From One Display
4 Sources + 1 Display = Greater Integration Options

Gefen's 4x1 HDMI Switcher routes high definition video in multiple resolutions up to 1080p plus multichannel digital audio from any of four sources. Four inputs accommodate the simultaneous connection of up to four high definition video sources, such as satellite systems and HD DVD players. The output sends the high definition audio/video signals to a high definition display. Switching is done via the IR remote that is provided with the unit.

Fully HDCP Compliant
HDCP (high bandwidth digital content protection) is a standard encoded into the video signal to prevent it from being pirated. If a source device is HDCP coded and is connected to a display or projector without the proper decoding mechanism, the picture is relegated to "snow" or in some cases, very low (480P) resolutions of the images. In order to see high resolution digital video with HDCP compliance, both the source, the display and anything in between must be equipped with HDMI connections that can enable HDCP decoding, such as the 4x1 HDMI Switcher.
How It Works
You simply connect all your sources to the Switcher's inputs. Then connect the display on the output port. Once the sources, the Switcher and the display(s) are powered and connected, you simply select which source you want to view using the IR remote.
Note: This HDMI product supports BOTH Audio and Video signals.

Share a Single HDTV Display with up to 4 HDMI 1.3 Video Sources
4 Sources + 1 Display = Greater Integration Options

Gefen's 4x1 HDMI™ Switcher routes high definition video in multiple resolutions up to 1080p plus multichannel digital audio from any of four sources. four inputs accommodate the simultaneous connection of up to four high definition video sources, such as satellite systems and HD DVD players. The output sends the high definition audio/video signals to a high definition display. Switching is done via the IR remote that is provided with the unit.


The current video source selection is always remembered. When a new source is connected and powered on, the Switcher temporarily routes that signal to the display. Should the new device lose power, the previous selection is restored. This feature is useful for temporarily verifying the functionality of new equipment.


HDCP (high bandwidth digital content protection) is a standard encoded into the video signal to prevent it from being pirated. If a source device is HDCP coded and is connected to a display or projector without the proper decoding mechanism, the picture is relegated to "snow" or in some cases, very low (480P) resolutions of the images. In order to see high resolution digital video with HDCP compliance, both the source, the display and anything in between must be equipped with HDMI™ connections that can enable HDCP decoding, such as the 4x1 HDMI Switcher.

You simply connect all your sources to the Switcher's inputs. Then connect the display on the output port. Once the sources, the Switcher and the display(s) are powered and connected, you simply select which source you want to view using the IR remote.
Note: This device is fully HDCP compliant.

Nella mia ignoranza non riesco sinceramente a capire cosa giustifichi una differenza di prezzo di 200 $ tra l'uno e l'altro

[The Believer]

In effetti è difficile capirlo

Il GTV appartiene alla serie Home, mentre l'EXT a quella "Pro", ma credo che il chipset sia il medesimo per entrambi gli switch, cambia la costruzione (L'EXT è in metallo, il GTV in plastica - pur di buona qualità).

Sicuramente 200$ di differenza sono comunque troppi.
