VDL Demonstrates New and Updated Professional Digital Radio Products at IBC 2013
VDL (Lyon, France) are demonstrating new and enhanced products for Digital Audio Broadcast (DAB & DAB+) and Digital Multimedia Broadcast (DMB) head-end and monitoring applications.

D-VAUDAX: Ensemble Multiplexer for DAB/DAB+/DMB networks

New 2U chassis, plus Service Linking and Journaline® updates

D-VAUDAX is now available in a new, compact, 2U chassis with an updated motherboard. The Linux operating system continues to provide long-term reliability and stability.

The latest multiplexer software release for D-VAUDAX includes a major update to support the new Service Linking use-cases defined in ETSI TS 103 176. This includes support for multiple LSNs.

Support for Journaline® data services has been added, with the choice of UDP/IP or FTP input.

The Service Provide Profile Management option provides a virtual Service Multiplexer. This option avoids the cost of additional service multiplexers and simplifies multiplex network management.

D-AUDIENCE-M: DAB+ Multi-channel Audio Encoder

New 12-Channel Audio Encoder with integral PAD Inserter and EDI output

The multi-channel D-AUDIENCE-M encoder for DAB+/DAB can be specified with up to 12 channels in a single, 2U unit. Audio settings are managed from D-VAUDAX Multiplexers and support a choice of 1+1 or spare-pool redundancy configurations.

The integral PAD-Inserter provides an efficient and cost-effective solution for adding DLS and Slideshow by eliminating the need for a separate data server.

Encoded audio streams are output to D-VAUDAX multiplexers via UDP/IP with packet-re-send error protection or EDI with a choice of packet re-send or forward error correction.

TRS: DAB/DAB+ Tunnel Emergency Voice Break-in System

New TRS Version 2 with major software update and integrated chassis

TRS enables tunnel operators to replace audio programmes with live or pre- recorded announcements, providing information and instructions in the event of an emergency. Break-in can be with live or pre-recorded announcements to provide safety information and instructions to vehicles in the event of an emergency.

Normal audio programmes are replaced by emergency announcements using the same audio bit-rates as the live programmes. RF frame synchronisation with the live transmission ensures a seamless transition and avoids receiver reconfigurations, which would otherwise lead to a delay in the reception of announcements.

TRS is available for 1 or 2 DAB/DAB+ multiplexes and 1 or 2 audio break-in languages.
