| 16-10 | Specific Infrastructure Requirements For Video Distribution Services |
| A. | Introduction |
| These requirements supplement the general requirements given to the Intrabuilding Communications Infrastructure Requirements section of these Construction Design Standards. They detail the specific needs for state-of-the-art video distribution systems. |
| The Office of Media Services, under the administration of the Vice Chancellor for Undergraduate Affairs, is responsible for audiovisual and technological resources used as part of the campus' regular instructional programs. General assignment classrooms, departmental teaching laboratories, and multi-media instructional spaces on campus require greater sophistication than in the past for technologies that are available to faculty and students as part of their educational experience and instruction of individual courses. Data technology developments are turning traditional visual and text materials into a digitized form; this combination of textual and graphic elements will be available upon demand wherever students and faculty assemble: classrooms, individual workstations, and the confines of residential communities, such as dormitories and private homes. The availability of these resources depends on reliable and continuous access to the campus network at virtually all locations where faculty and students convene. |
| The requirements described below refer to general provisions of connectivity, the capacity for possible future expansion of the network, and the most probable applications. This document does not consider the technology, software, or programmatic uses that can be utilized once the campus and its buildings are ubiquitously interconnected. The primary focus is that without this infrastructure and its possible connections, the potential of the new technologies will not be realized. As we progress towards an electronically distributed format for conducting business on campus, including teaching and learning experiences, the continuance of our institutional vitality will become interdependent on this communications infrastructure. |
| B. | Density Of Video Outlets |
| Video outlets should be provided wherever real-time and full-motion video services might be required over the life of the building. It is not necessary to wire each outlet, but providing the conduit and outlet box during general construction will be much less costly than retrofitting them later. Therefore, in designing new or renovated facilities the following rules should be applied: |
| 1. | Density in office space: Video distribution is not normally provided in individual office space, but video may be required in conference rooms and lounge areas. It should be assumed that all general-purpose meeting rooms and library spaces should be connected for two way video capability. In these areas a 4 x 4 deep box with a 3/4" conduit to the Communications Service Distribution Closet (CSDC) should be used. |
| 2. | Classrooms (Refer to the three drawings at the end of this section for conduit sizes and other requirements for a typical classroom): Current practice is to provide video distribution to each general purpose classroom. Smaller classrooms have one or two video monitors at the front of the room, whereas larger lecture halls and selected classrooms use large-screen video projects, usually suspended from the ceiling, using a pipe mounting or retractable lift structure for securing the projection device. Remote controlled power relays are included for operation from the OMS video control room in Dwinelle Hall or from a local equipment panel. Teaching laboratory rooms, which includes chalkboards, should be considered a classroom/teaching environment and therefore be equipped for possible video display. |
| Current practice is also to include a provision for local video tape and disk playback, with equipment mounted in a metal rack type cabinet enclosed in a closet or enclosure at the front of the room. This installation involves only local wiring and should be discussed with Media Services at the time of design. | |
| 3. | Residential Units: A video/CATV connection should be provided for each resident room in a residential unit. Additional connections should also be provided in lounge and central study areas, such as the Academic Study Center complexes for each cluster of dormitories. This location can often be the same room or located near the Computer Lab within each building. |
| C. | Communications Service Entrance Room |
| The main video distribution equipment for a building may be located in the CSER. The area dedicated to video distribution must have a sheet of 4' x 8' x 3/4" AC fire retardant plywood mounted on the wall. There should be a dedicated 20 amp, 120 VAC isolated ground duplex power outlet. The video distribution equipment rack may be located in the CSER. Space should be allocated for a 22" wide x 35" deep x 6' cabinet, with 3' clearance front and rear. |
| D. | Communications Service Distribution Closets (Csdc) |
| The CSDC is where interconnection is made between cables from the classrooms or viewing rooms and the video distribution trunk cables. Electronic equipment for video distribution may be located here in addition to, or in lieu of, equipment in the CSER, depending on the number and distribution of classrooms and viewing rooms. A 4' x 8' x 3/4" AC fire retardant sheet should be mounted on a wall, with space allocated for a 22" wide x 35" deep x 6' rack cabinet. A dedicated 20 amp, 120 VAC isolated ground duplex power outlet should also be provided. |
| E. | Communications Outlets |
| Video connection locations should be clustered, wherever possible, with other communications connections, such as telephone and data. General Assignment Classrooms recently renovated under the Classroom Renovation Projects, like Lewis 100 and Dwinelle 155, are typical examples of this clustering approach. Specific installations will vary depending on the size of each room and the video display equipment used. |
| F. | Relationship To Telephone And Data Wiring |
| The communications system as conceived is a shared one. The limitations set forth in the data sections of this set of guidelines and the general provisions of the system as outlined for the infrastructure will safeguard against electronic interference and interruptions that could otherwise occur during operation of the campus network. The Office of Media Services (OMS), Data Communication and Network Services (DCNS), and Telecommunications (TELCOM) should be consulted at all phases of Capital Projects. These three service units are responsible for the on-going operation of the systems described in these Construction Design Standards; they are committed to reliable and safe operation of campus communications. Collaborative and inclusive involvement of these three units in development of the campus infrastructure and its implementation is essential to its successful completion and continual improvement. Coordination with the University project management to schedule consultations with these units. |
