Context : migration to IP networks

• ISDN fading out on most of the countries
• Satellite is quite expensive
• IP access providers propose offers for reliable transport over IP networks
• Lower OPEX
• More flexibility

IQOYA *LINK (1/2)

• Full-duplex stereo IP audio codec

○ 1U rack 19’’ ○ Selectable audio I/Os: Analog, AES/EBU, Livewire, AES67, RAVENNA ○ 1 encoding and 1 decoding ○ Unicast, multicast, multi-unicast, multi-multicast ○ Supports standard RTP (ACIP), Icecast/Shoutcast, MPEG-TS/IP

• Robust IP streaming

○ Two network ports: control / IP audio, backup network, redundant dual streaming ○ Digigram Fluid IP streaming engine offers all mechansims to get a reliable transport over unmanaged and managed networks ○ Real time metrics on the received RTP stream ○ VLANs with QoS ○ IGMPv3

IQOYA *LINK (2/2)

• In-band auxiliary data tunneling (8 GPIOs, serial data through RS232 port or IP)
• Multiple fail-over solutions

○ 3 backup levels ○ SD card for local backup sound files, save/load configuration ○ Switchable hardware by-pass of audio I/Os in case of power suply failure

• SDHC card reader, LCD, keypad and headphones jack on front panel

1-a Reliability (hardware)

Rock-solid, dedicated hardware platform

• Low consumption (<10W) fanless design
• Robust ARM-based processor (AEC-Q100 qualified - Automotive)
• Embedded Linux distribution sized by Digigram
• Very high field measured MTBF > 150 years (more than 3000 installed units)
• Strong radiated & conducted EMI resilience : 10 V/m & 10V
• Lightning protection on network ports

<=> Designed for tansmitter sites

1-b Reliability (Fluid IP streaming engine)

• Management of network errors

○ Reordering of received packets ○ Management of duplicated packets ○ Jitter buffer

• Choice of FEC schemes to
• vercome packet losses on a

network path.

• Dual redundant Streaming with

time diversity to get rid of packet losses by using two separate network paths

• AAC Fraünhofer codec error

concealment

• Constant latency between

encoder and decoder through smart synchronization on the incoming IP stream

Digigram confidential

2 - Audio service continuity

• Up to four configurable decoding priorities
• Priority sources: RTP stream, HTTP stream, sound file / playlist on local SD

card, audio inputs

• Configurable switching criteria: IP stream loss and recovery durations
• Playlists and sound files on SD card managed through FTP
• Silence detection on the audio inputs: alarm, stop/start streaming
• Silence detection on the decoded IP audio stream: alarm, switching to backup
• Fail-over in case of power supply failure

Hardware by-pass of analog and AES/EBU inputs to outputs Manually switchable from rear panel for the AES I/O, and for analog I/Os
