Introduction

■ Multiple Video Input with Single Modulation Output

ST-7000 Single Channel High-Definition (HD) modulator provides single channel delivery of multiple

video/audio digital/analog sources over signal coaxial cable. HD video output resolution can be up

to 1080p @ 30 fps with adjustable output power level from 70 to 100

dBµV

in 1 dB step.

Output frequency ranges from 50 MHz to 860 MHz in 6 MHz, 7 MHz or 8 MHz channel bandwidth

depending on the modulation technique.

The operation of ST-7000 is intuitive by using on-panel keypad and 2.4” color LCD screen.

■ Audio Codec

Audio encoding is automatically selected by the Modulator to reach the best quality according to local

modulation technique.

AC3 2.1 Dolby Digital Audio coding applies to ATSC (8VSB) broadcasting in North America.

MPEG MPEG-2 Layer 1 audio coding applies to DVB-T broadcasting in Europe and South America.

ACC Advanced Audio Coding for MPEG-4 applies to ISDB-T broadcasting in South America and certain

ATSC (8VSB) broadcasting in North America.

■ Video Quality

Video quality is optimized by determining the size and the speed to transmit MPEG packets to the TV.

The packet latency and delay variation are adjusted automatically by the Modulator to reach the best

video quality and performance on the TV.

ST-7000 Series HD Modulator

Before Installation

■ Choose Modulated Output Frequency for HDMI Video on TV

•Modulated output frequency of HDMI video can be any existing channel frequency available from

your local Channel Plan.

•Depending on the modulation technique of over-the-air broadcasting TV or Cable TV used in your

area, refer to the corresponding appendix for Channel Plan information.

•Select an unused or an unimportant channel from the Channel Plan as output frequency of HDMI

video.

• If you are unsure about which output frequency to be used for HDMI video

◊ Pick a frequency between channel gap, make sure it’s 6 MHz or 8 MHz away from the previous

and the next channels.

◊ Use the recommended frequency indicated on the corresponding Channel Plan appendix.

◊ Use the default frequency selected by the Modulator.

•Modulated output frequency and channel number can be configured from the LCD menu or Web

Configuration page.

• Follow the instructions of this Start Guide to set up output frequency and channel number to

watch HDMI video on your TV.

•Your TV needs to learn the HDMI video channel by auto or manual channel rescan. Refer to the

user’s guide of your TV set to practice the rescan for channel detection of HDMI video.

■ Combining (Cable) TV Signals from Service Provider (e.g. Comcast)

•In order to combine the existing TV broadcasting channels from service provider, it’s necessary to

select an output frequency and output channel (ATSC only) for Modulator’s HDMI video. The

channel information of your local over-the-air broadcasting or local Cable TV service can normally

be found online or from the channel listing table provided by your service provider.

• For business installers, a handheld spectrum analyzer up to 1 GHz can be helpful to make the

installation easier and faster although it’s not mandatory.

• If the modulator output is going to feed a Digital Cable Converter box or a set-top box, some

service providers offer a dedicated channel (and frequency) for modulated video and some service

providers may need a specific PID to be configured by the Modulator for MPEG streams to be

recognized by the set-top box. Refer to the section of MPEG Transport Stream Parameters for PID

setup.

• If the output power level of the Modulator is too high, it may oversaturate the TV signals delivered

by service providers. It’ necessary to lower the output power level or use an attenuator to reduce

the oversaturation.
