Z-Band, Inc. High Definition Video Distribution System Preliminary Specifications for Design Applications

Z-Band, Inc. High Definition Video Distribution System Preliminary Specifications for Design Applications

1.0 Introduction

Describe the Owner's site-specific requirements. Provide details concerning the intended use and implementation of the video or other elements to be distributed over the Z-Band RF High Definition Video Distribution System. The description must comprehensively describe the expected use of the System and may be expanded to include information on the actual channels to be employed on the System. Information on a head-end for the System to incorporate CATV, satellite earth station receiver, off-air and local origination channels may also be included. If the head-end is to be a part of this project, then appropriate sections for the commissioning and testing of the complete System should be incorporated in the document.
This document may be accompanied with floor plans and details of the desired System. At a minimum, the owner must identify the existing conditions including the facilities and the existing cable system. If no cable system exists, then a separate or combined cable system specification should be generated.
The Owner requires a RF High Definition Video Distribution System capable of delivering up to 134 RF video channels (6 MHz NTSC Channels containing NTSC, ATSC and QAM modulated programs) and IP Video over an installed Category 5e/6/7 shielded or unshielded twisted pair cable system. The System shall utilize a cable plant comprised of a TIA/EIA 568 compliant horizontal distribution cable system and a coaxial and/or single mode fiber backbone system. The System shall employ Active Automatic Gain Control Electronics to adjust the video signal levels to each TV and shall be capable of supporting up to 14,000 connected devices.  The System shall support bi-directional RF transmission for backbone interconnections. Note: see paragraph 2.01.G for Category 5e frequency limitations.
Optional – A combination of outside plant coaxial and optical fiber backbone system will be deployed to connect between several remote buildings on the campus or office complex.
The High Definition System shall provide video distribution to rooms in the main building and to the rooms in each of the remote buildings. The System components shall be installed in racks in the main equipment room and throughout telecommunications closets in the building/campus. The System components shall be co-located with the existing Category 5e/6/7 termination hardware to facilitate proper patching from the patch panels and the Video Distribution System equipment. The Installer shall configure the System and place the System components throughout the facility as required. After installation, the Installer shall conduct a series of tests to ensure that the System is fully operational to vendor specifications in all areas of the building.
Optional – The Contractor shall be required to commission the System and live test the System in its entirety. The commissioning shall include the power up of all equipment, the tuning of the head-end, the placement of all ancillary equipment and the final adjustment of the televisions and video input devices.

2.0 Products

The RF High Definition Video Distribution System shall consist of user-configurable and auto-configuring components, which facilitate simple modifications and additions to the System. The System shall allow cascading of units up to four levels deep. All passive and active electronic components of the System shall be FCC certified to operate on a Category 5e/6/7 cable plant, shall be compliant with "FCC Regulations, Part 15," and shall be UL/CSA listed. Additionally, the components shall be designed with passive circuitry to simultaneously allow transmission of IP Voice, IP Video, data or other low voltage signal types on the pairs of the Category 5e/6/7 cable which are unused by the System.
2.01 RF BROADBAND HIGH DEFINITION VIDEO DISTRIBUTION HUB ("HD GigaBUD"):

A. Provides a method of distributing up to 134 RF modulated NTSC, ATSC or QAM channels and seven sub-channels (T7-T13) over Category 5e/6/7 in a TIA/EIA 568 horizontal cabling infrastructure. The "HD GigaBUD" requires a 23dBmV CATV flat NTSC signal input for maximum performance. The optimum ATSC/QAM input signal level is 17dBmv for (Digital) and 20dBmV (Digital) for cable box applications.
B. The "HD GigaBUD" shall be self-configuring and plug-and-play so as to easily accommodate adds, moves and changes, and maintains proper signal level and slope to all drops.
C. The "HD GigaBUD" shall combine, split, amplify and equalize the signals so as to achieve a high picture quality and to be in compliance with "FCC Regulation, Part 15".
D. The "R" series "HD GigaBUD" shall have Return Video channels T7 - T13 & channels 2 - 6 available; the Standard unit provides Return Video channels on T7 - T13 only.
E. The "HD GigaBUD" shall cascade up to four levels deep and accommodate up to 14,000 outlets.
F. The maximum distances between the cascaded "HD GigaBUDs" are: 400' with RG-6 coaxial cable, 600' with RG-11, and 1050' with .500 semi-flex coax. These shall reflect an attenuation budget of 12.5 dB at 240 MHz.  Single mode fiber up to 25km may be used to cascade "HD GigaBUDs".
