Benefits of using IQOYA the products

IQOYA *LINK and *LINK/LE Benefits Proof Value for money Most of the features are included in standard: FECs, dual redundant streaming, VLANs, QoS, SNMP, Fraunhofer AAC codecs Lower your OPEX Very high MTBF, Low consumption, very stable Fluid IP streaming Guarantee the audio service on your transmitter sites 3 configurable backup levels with switching criteria Backup on IP stream, audio inputs, local SDcard Hardware by-pass of audio I/Os in case of power supply failure 2 Eth ports, QoS, VLANs, IGMPv3, FECs, dual redundant streaming, Take the most of your managed or unmanaged networks real time metrics on received IP streams Full SNMP support (SET, GET, Traps) Use any popular professional software applications for Dataminer driver supervision Supported audio I/Os: analog, AES/EBU, Livewire, AES67, RAVENNA Connect IQOYA to legacy audio or IP audio in-house infrastructure 10 Digigram confidential

Presentation and assets of IQOYA *LINK and *LINK/LE

IQOYA *LINK & IQOYA *LINK/LE overview and assets

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 13 Digigram confidential

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 14 Digigram confidential

IQOYA *LINK/LE Same as IQOYA *LINK except: ○ No LCD and keypad on front panel ○ 4 GPIOs instead of 8 15 Digigram confidential

Assets 1/ Reliability 3 / Audio quality 2 / Audio service 4 / Interoperability continuity Digigram confidential

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 17 Digigram confidential

1-b Reliability (Fluid IP streaming engine) ● Management of network errors ● Dual redundant Streaming with ○ Reordering of received time diversity to get rid of packet packets losses by using two separate ○ Management of duplicated network paths packets ● AAC Fraünhofer codec error ○ Jitter buffer concealment ● Constant latency between ● Choice of FEC schemes to encoder and decoder through overcome packet losses on a network path. smart synchronization on the incoming IP stream 18 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 19 Digigram confidential

3- Audio quality Digigram expertise in designing broadcast grade hardware audio I/Os Wide choice of included audio formats: ● PCM 16/20/24 bits ● ISO MPEG 1/2 layer II, and layer III ● MPEG-4 AAC LC, HE-AACv1, HE-AACv2, AAC-LD, AAC-ELD (Fraunhofer) with error concealment ● Opus Optional audio format: CSR apt-X Enhanced 20 Digigram confidential

4- Interoperability Supports the following audio connectivity: ● Analog, AES/EBU, Livewire, AES67, RAVENNA Compatible with third party codecs thanks to the standard ACIP ● IP audio streaming Compatible with all SNMP supervisors ● SNMP control, monitoring, alarming (SET, GET, TRAPs) ○ SNMPv2c MIB included ○ Supported by Skyline Dataminer ● Can be used in symetrical RTP for temporary remote IP ● contribution 21 Digigram confidential
