D-AUDIENCE-M is a Digtial Radio Audio Encoder that uses the high-efficiency MPEG-4 coding standard HE-AAC-V2 (ETSI TS 102 563) for DAB+ and the MPEG Layer II Audio Encoder (ISO 14496-3) for DAB.

As part of an integrated head-end system, D-AUDIENCE-M Encoders are remotely managed via IP from a VDL D-VAUDAX Multiplexer.

Encoder Inputs

D-AUDIENCE-M can be specified with a choice of audio input configurations:

  • Up to 4-channels analogue (balanced) and up to 4-channels digital (AES/EBU)
  • Up to 16-channels digital (AES/EBU)
  • Up to 16-channels Livewire (Audio over Ethernet)

Encoder Outputs

Audio output to a VDL D-VAUDAX Multiplexer is via IP (LAN or WAN).  Output protocol options are UDP/IP with packet re-send capability error protection, or EDI output with a choice of forward error-correction or packet re-send.

Each audio input can be configured with multiple outputs at different bit-rates and coding formats (DAB+ and DAB) for use on separate ensembles.

Programme associated Data (PAD)

D-AUDIENCE-M includes a PAD (Programme Associated Data) Inserter with FTP input.  Alternatively, PAD can be received via an IP connection from a VDL D-VAUDAX Multiplexer, or VDL PAD-Server.

Monitoring

In addition to providing status via the VDL D-VAUDAX Multiplexer, D-AUDIENCE-M can be monitored via SNMP.

Connectors

Audio encoder connector options include flying leads with XLR connectors or rack-mount connector panels with XLR connectors.
