Modulation and distributing video

tecLAN, iLAN, and iSAT models are conﬁgured to distribute your own televi-

sion channels through out your home. In order to distribute your own televi-

sion channels a device called a modulator is needed to turn line level signals

(the RCA style outputs on your satellite or DVD for example) into “modu-

lated” television channels.

UStec carries a series of modulators from 1 to 3 channel (this means up to 3

devices can have their own separate channels) in mono and stereo versions.

UStec modulators have been speciﬁcally designed to work with our systems

and have the necessary dB output to drive a whole home (35dB). UStec can

not guarantee the results when using non-UStec components.

Let’s use a typical scenario to

understand how a modulator

works. Lets assume we want to

watch a DVD in every room in the

home.

Here is the picture of the front a

of the 1 channel modulator part number MOD1CH.

Using RCA style patch cords connect the Video out on the DVD to the Video

port on the rear of the modulator (Yellow jacks). Next connect the left and

right audio from your DVD to the left and right inputs on the modulator.

This particular modulator is a

mono modulator, which means

that the left and right audio sig-

nals get mixed together. UStec

offers stereo versions if you are

interested.

On the front of the modulator select the up and down buttons and turn the

modulator to channel 120.

Your UStec system has a specialized ﬁlter to block any

modulated signals from harming the cable companies return path. The return path is

where cable modems and interactive set top boxes signals go back to the cable com-

pany. Even if you do not utilize these cable services, without the ﬁlter you could effect

your entire neighborhood.

If you have cable television service, UStec strongly recommends modulating

to channels 118 and higher. Cable companies have been allocated to 750

MHz for their digital signals. Channel 116 ends at 750 MHz. This eliminates

any possible problem with wiping out a series of digital channels.

For those with off-air antennas you can safely modulate on channel 60 and

higher.

Power off the modulator.

Once the channel has been set (120 in our example) connect a coax cable to

the cable port on your modulator and plug the other end into the INTERNAL

port on your tecPort. Satellite users plug the modulator into the port labeled

modulator on the CX-2060 diplexer that came with your system.

Power on your modulator and device (DVD in this example)

Now your DVD should be viewable on every channel in the home on channel

120.

NOTE: You can NOT modulate to a channel that is already occupied by another

channel. If there had already been programming at channel 120 as the explanation

above, suggested would need to pick another channel that is free and at least 2 chan-

nels away such as 122.

Modulation and distributing video

Here is the above steps again.

Connect the RCA feeds from the device you want to view everywhere in your

home to the modulator.

Set the channel to the desired channel (>117 with CATV or >60 on UHF)

Power down the modulator

Connect the coax output on the modulator to the Internal Input on the

tecPort, or to the port labeled Modulator if using satellite.

Power up the modulator.

Turn your TV’s to the channel set in step 2

Enjoy.

Set Top Box note:

One other important note here pertains to cable companies and their set-top

box. Unfortunately most of the cable companies set-top boxes are designed

to only pass their signals and to block all others. This adds one more step to

the task of distributing modulators.

If your TV has dual inputs then your problem is already solved. Connect the

raw TV feed into Antenna A (or RCA input) and the cable box into antenna B.

All your modulated signals are available on Antenna A and your set-top is on

Antenna B.

If you only have one set of inputs, then a cable box combiner kit is needed.

Contact your UStec dealer for one. This solution routes your modulated sig-

nals around the cable box to simply solve the issue.

Satellite Internet Hookup

Two-Way Satellite

Satellite Internet is a still maturing market. Satellite Internet has signiﬁcant

challenges most IPS do not face. This is due to the fact the signals need to

travel more than twenty three thousand miles to the satellite in orbit and

back to the ISP headend on earth before sending the return signal back to the

homeowner. This leads to large latency or delay in time for a task to be com-

pleted.

Many networked applications do not do well with long latency, so the satel-

lite Internet companies have come up with alternative methods for making

reliable connections.

The satellite Internet companies have specialized hardware which encapsu-

late the normal TCP Internet packets into a more satellite friendly versions.

This makes it more difﬁcult to share these broadband technologies than does

cable or DSL modem technologies.

Typically UStec recommends putting the broadband equipment into the tec-

Center for distribution throughout the home. Due to the satellite technolo-

gies available at the time of this writing, UStec will recommend that the

satellite equipment be mounted at the location of the designated computer.

(We’ll share that computer for whole house distribution)

Later in 2002 DirecWay will have available an add-on product to its lineup

that will allow for the broadband sharing of its connection. At this time size

is still a limitation (3 different hardware boxes) so the connection will still

need to take place outside the tecCenter.

The following diagram will show how to set the computer hardware up to

share the broadband Internet connection
