- Main Features:
- Flexible in application: The codec is designed for studio-to-studio, studio-to-transmitter links and cross-media tasks. Even synchronization with microsecond accuracy is possible by an implemented latency control (useful for simultaneous signal output of all decoders of a network or for audio description). In addition, audio streams can be combined to multichannel streams. An optionally available FM Tuner offers further functions for fallback or backup and rebroadcasting. The Easy2connect feature provides operators as well as reporters with an easy to use connection establishment (SIP phonebook) while being in the field.
- High compatibility: The IP-4c supports a wide range of protocols for streaming, control and monitoring (e.g. EBU TECH 3326, AES67, Ravenna, Livewire+, Dante, SMPTE ST 2110, PTPv2, RTSP, SAP, SIP, Discovery, Bonjour, SNMP, HTTP, HTTPS, FTP, FTPS or Ember+ and more). Furthermore, the exchange of additional information like GPIO and ancillary data between the audio networks is possible.
- Pay as you grow: All soft- and hardware components are individually combinable. The scalability from one to four audio channels using software licenses gives you flexibility in planning your network and reducing your costs.
- Multi-format audio coding: A variety of audio coding algorithms is included, supporting formats such as MPEG-1 Layer 2, MPEG-1 Layer 3, the MPEG AAC familiy including the new xHE-AAC and AAC-ELDv2, OPUS, Ogg Vorbis, PCM and Enhanced aptX. The optional Dolby Digital Pro Codec adds support for Dolby Digital (AC-3) and Dolby Digital Plus (E-AC-3). Dolby E can be supported on request. The device can be upgraded with the FRAUNHOFER DAB+ Encoder to support multi-channel remote audio coding for DAB+ systems. The interface to the multiplexer can be realized with EDI/STI-D or FhG MuxEnc.
- Transmission robustness: Dual Streaming and Pro-MPEG FEC ensure rock-solid IP transmission or you go beyond with Stream4Sure (the decoder is able to switch seamlessly in between up to 4 streams with different audio qualities forwarded by the encoder).The Reliable User Datagram Protocol (RUDP) ensures highest packet recovery with minimum bandwidth and low latency. Two hot pluggable power supplies guaranteeing fail-safe operation perfect the whole concept.
- Smart management: Configuration set-up via an easy to use web interface for general settings as well as for backup or fall back. For remote control, the codec offers various possibilities – HTTP, FTP, Telnet, NMS, SNMP. Perfect synchronization can be achieved by PTPv2 and latency control.
