BUDGET: 10 crore INR and above (USD1.48 million and above)
Project Overview
• Executed the complete AV, conferencing and control system integration for the new Raipur Vidhan Sabha building, covering the Auditorium, the Sadan (main assembly hall) and the Meeting Rooms.
• Deployed 8 x 105-inch Samsung displays and 7 x Planar LED video walls across the Auditorium and Sadan.
• Installed 13 x 86-inch Samsung displays and 11 x seamless presentation switchers in the Meeting Rooms.
• Positioned 14 Sony PTZ cameras for live coverage and recording.
• Installed well over 400 speakers of different types across the three areas, driven by Extron, Bosch and Dynacord processing and amplification.
• Delivered the Bosch DICENTIS/DCN conferencing and voting system, providing around 360 delegate and chairman positions — 109 in the Sadan and 251 across the Meeting Rooms (117 flush-mounted plus 134 CCSD1000 units).
• Enabled 32-channel language interpretation, synoptic microphone control and automatic camera tracking.
• Unified control of displays, audio and camera presets through a single Kramer-based touch-panel control layer.
• Used EN54-certified speakers wherever public-address and life-safety rules applied.
What did the client want to achieve?
• Run parliamentary proceedings without interruption.
• A new, latest-technology conferencing facility with high-end active LED displays.
• Ensure reliable electronic voting.
• Provide clear multi-language interpretation for delegates.
• Deliver camera-tracked recording of proceedings.
• Present a modern, presentable look for the new assembly building to delegates, staff and visitors.
• Meet EN54 life-safety certification requirements for sound reinforcement equipment, as expected in a public building.
• Keep day-to-day operation simple enough for Vidhan Sabha staff to manage without specialist AV knowledge.
Scope of work your company was involved in
• Delivered supply, installation, testing and commissioning of AV, conferencing and control systems across three areas of the building.
• Auditorium: video displays, PTZ cameras, sound reinforcement (wall and ceiling speakers through amplifiers and mixing console), plus associated cabling and racks.
• Sadan: full Bosch digital conferencing and voting installation — 109 delegate and chairman units, central control units, interpretation consoles and headphones.
• Sadan: also included video walls, network switches and the touch-panel control system.
• Meeting Rooms: same conferencing approach repeated using a mix of flush-mounted and CCSD1000 discussion units across multiple rooms.
• Meeting Rooms: matching displays, switchers and amplification.
• Structured cabling (HD-SDI, HDMI, USB, CAT6 and multicore conference cable) and rack infrastructure supporting all of the above.
What key challenges were faced?
• Unifying two different Bosch product families — flush-mounted DICENTIS units (Sadan and some Meeting Rooms) and CCSD1000 discussion units (other Meeting Rooms) — into one consistent conferencing experience.
• Routing both product families to a common set of central control units so operators only had to learn one workflow.
• Managing cable runs between equipment racks and delegate desks, cameras and displays that stretched well beyond standard HDMI or USB capability; the camera backbone alone ran to around 700 metres of HD-SDI cable.
• Operating in a demanding RF environment with dozens of wireless microphones and interpretation channels running side by side, where any dropout during a live sitting would be highly visible.
• Absorbing a mid-project change of the wireless handheld and lapel microphone system without slipping the schedule.
• Sourcing speakers that satisfied mandatory EN54 life-safety certification while still giving clear, broadcast-quality speech reproduction elsewhere — no single speaker choice could be used everywhere.
How were those challenges resolved?
• Gave the Sadan and the Meeting Rooms their own set of Bosch DCNM-APS2 central control units feeding the same DCNM-FBD2 interface backbone, so the operator interface behaved the same regardless of room or unit type.
• Solved the long-distance signal problem by extending HDMI over HDBaseT with 72 pairs of Kramer transmitters and receivers.
• Kept camera video on a dedicated HD-SDI backbone into a Blackmagic video matrix rather than stretching standard cabling beyond its design limits.
• Improved RF reliability by pairing wireless microphone systems with directional antennas and antenna splitters for even coverage across the building.
• Absorbed the mid-project microphone change by procuring the replacement Bosch wireless handheld and lavalier sets as an additional item against the original supply list, avoiding delays.
• Used EN54-certified Bosch speakers specifically where fire and life-safety compliance was mandatory, and commercial-grade Electro-Voice speakers elsewhere for the extra intelligibility a large public hall needs.
How has your work helped the client?
• Gave the Vidhan Sabha a single, unified system to run its proceedings — voting, interpretation and camera-tracked recording work together instead of as separate systems requiring manual coordination.
• Delivered an installation that is fully commissioned and in day-to-day use for assembly proceedings.
• Provided delegates and visitors a noticeably more modern visual experience across the Auditorium, Sadan and Meeting Rooms compared with the previous setup.
What are you most proud of about the project?
• The scale of the conferencing deployment: 109 delegate and chairman positions in the Sadan alone.
• A further 117 flush-mounted and 134 CCSD1000 units spread across the Meeting Rooms, all running on the same Bosch DICENTIS/DCN platform.
• Delivering 32-channel interpretation and automatic voting across the full deployment.
• Bringing together large-scale delegate hardware with EN54-certified audio, PTZ camera tracking and a single Kramer control layer.
• Achieving all of this without compromising the operational demands of a live legislature.
