9X1 HDMI Scaler Switcher - 1080p
http://www.hdtvsupply.com/hdmi-scaler-switcher.html
9X1 HDMI Scaler Switcher Input Resolutions Converted to 720p/1080p (not 1080i):
HDMI1/HDMI2:
480i
480p
576i
576p
720p (50HZ; 60HZ)
1080i(50;60 HZ) and
1080p(50HZ; 60HZ)
This 9X1 to HDMI Scaler & Switcher is capable of switching between 9 sources, scaling any one of the sources up to HDMI. The output resolution is also selectable between 720p and 1080p. It does not output a 1080i signal for interfacing with a 1080i TV or projector, only 720p and 1080p.
The 9X1 HDMI Scaler Switcher will convert practically all analog video formats to HDMI, including component, composite, S-video, VGA, stereo audio (integrated into the HDMI output signal) and SCART. It also up-scales the resolution to only 720p and 1080p. Again, 1080i is not supported.
Switching between your many sources is easy with the included remote. This 9X1 HDMI Scaler Switcher is HDCP and HDMI 1.3 compliant, supporting DTS HD and Dolby True HD audio formats as well.
If you prefer, you can also control this switch/converter/scaler with RS-232 automatically. 4:3, 16:9, and 16:10 are input display modes supported in standard definition, and 16:9 and 16:10 are the supported widescreen inputs.
