1.       What is the HDMI Extender

The HDMI Extender allows you to extend the length of HDMI cable used in your theatre system. It is especially useful in DLP projector systems where the source and projector are far apart. The unique circuitry automatically provides compensation for DVI, HDMI cables by equalization, buffering and de-jittering the TMDS signals which degrade over long cable runs. The HDMI Extender \"cleans\" up all signals to ensure error free transmission

2.       Where should I place the HDMI Extender

The HDMI Extender should be placed as close to the Projector or Monitor as possible to realize its full capability. In other words, HDMI Extender should be placed so that the LONGER cable is at the HDMI Input

3.       I have 2 HD Displays, how can I switch between the 2 displays

You can easily switch between the 2 HD Displays by using the 4x2 HDMI Cross switch. The 4x2 HDMI cross switch has 4 Inputs and 2 Outputs. The 4x2 HDMI Cross switch has the ability to let you watch 2 different programs simultaneously. For example, you can watch a HD Sports event on your projector and a DVD or Computer can be displayed on a secondary HD display all at the same time! The Cross switch does not split or show the same program on both outputs. The advantage is that you can watch 2 different programs on 2 displays or simply switch between both displays. A huge benefit is for viewers with a projector and a LCD/Plasma who then can use the cross switch to view the projector on \"special\" events in order to save wear and tear on the bulb life.

4.       What devices currently use HDMI

The list HDMI HD video sources is growing. It all started with Upscaling DVD players which simply converted standard 480i formatted video and upscaled it to 720 i/p and 1080 i/p to match today\'s HDTV\'s.

5.       Can I split HDMI and watch the program on 2 HDTV

HDMI can be split and distributed to multiple HDTV using a 1x2 HDMI splitter Distribution Amp. There are some HDMI \"Y\" cables that can physically connect 1 HDMI source to 2 HDTV, but that will not work. You must use a 1x2 HDMI splitter Distribution Amp. A passive \"Y\" cable will not be able to process the HDCP content protection protocol and will cause the HDTV to shut down. The 1x2 HDMI splitter Distribution Amp has internal HDCP keys that can independently handle multiple HDCP sessions and allow 1 single HDMI program to be displayed on multiple HDTV.

6.       How to distribute HDMI over standard Ethernet Cables

It is possible to distribute HDMI over a pair of standard Ethernet cables by using HDMI to Ethernet converters. The HDMI Ethernet converter enables transmission of 1080P HD HDMI digital video and audio over a pair of standard Ethernet CAT5/6 cables.

Using HDMI over Ethernet Transceiver allows installers to use standard CAT 5/ 6 cables for ease of installation.

Ethernet cables and connectors are easily field terminated thus allowing installers to easily install the proper length cable needed for ultimate flexibility and eliminate logistics problems of having custom length HDMI cables.  No need top pre-measure and customer order cables

7.       How do I get surround sound to my Audio Receiver from HDMI

There are several ways to connect sound from your HD source player to your Surround Sound System.

If your Audio Receiver has HDMI audio processing capability- Simply connect the HDMI source to your Surround System via the HDMI connection.

If your Audio Receiver only has Optical Audio surround sound input- Octava HDMI distribution amplifiers provide HDMI to Optical audio ( 5.1)conversion. You can connect your HDMI sources to the Octava HDMI Distribution Amplfiers and audio will be converted to Optical format AND will be available on the HDMI ouput and the Optical output. This allows you to get audio directly to the HDTV AND/OR thru the Surround Sound Receiver.

8.       I have a PS3, how can I get 7.1 Analog Audio to my audio system

The PS3 can decode 7.1 LPCM. However it does not have any 7.1 Analog Audio Outputs for integration with Audio systems requiring 7.1 Analog Inputs. The HDSA71 can take the decoded 7.1 LPCM from the PS3 and convert to 7.1 Analog Audio outputs so you can connect to your high end 7.1 audio receiver.

The HDSA71 also has an additional Auxiliary 5.1/7.1 Analog Audio inputs that allows you to switch in a secondary 5.1/7.1 Analog Audio source.

9.       My HDTV only has DVI. How do I route HDMI/DVI video and Stereo sound to it.

Switching Multiple digital video and Stereo Audio to a DVI input HDTV may be difficult because only 1 set of L/R stereo Audio Input is mapped to the DVI input.

If you have multiple HD sources that need to be shared with a DVI input only HDTV, you can use the HDDA31 which integrates HDMI/DVI video switching with 3 sets of L/R Stereo Inputs. This allows easy switching of 3 HDMI/DVI sources and L/R stereo with your DVI input HDTV

10.   I have a Wii with component video output. How can I connect to my HDTV with HDMI

If you have a video source with only COMPONENT video , for example the Wii, you can use a Component to HDMI converter to send the video to the HDTV via HDMI. The component video to HDMI converter also has a L/R audio input that will convert the audio to HDMI. The advantage is that you can consolidate all your HD video connections to HDMI and run 1 single cable from the converter to the HDTV. Great for Projector systems.

11.   Can I send HDMI, Infrared and Optical Digital Audio over long distances from source to HDTV.

If your HD sources and HDTV are far apart and you need to control the source equipment via I.R. You should use the HDMI Ethernet+I.R. Extender. This device allows you to carry HDMI, I.R. and Optical Digital Audio over 150ft using a pair of standard Ethernet cables. Now, you can locate your source far from your HDTV and have complete control with I.R. using one simple solution. Optical Digital Audio can also be carried from source over 150ft to a remote Surround Sound System.

12.   What is HDCP

High-bandwidth Digital Content Protection (HDCP) is a form of digital content protection developed by Intel. HDCP allows the Content providers ( movie, tv studios) to encrypt the digital content over the DVI or HDMI interface so that unauthorized device, non-HDCP device can not view the content. In order for one to view a HDCP protected video source, both the source ( dvd player, settop box) and the display must be HDCP licensed. HDCP protocol is carried over 2 lines, SDA and SCL of the DVI or HDMI connector and uses I2C physical layer protocol. HDCP is a robust encryption algorithm that help content providers combat piracy and unauthorized distribution of the HD content.
