4 RELEASE NOTES

4.1 Version 3.06c

What’s new in version 3.06c

● Dual streaming: the redundant stream can now be delayed up to 3 seconds instead of 1second in previous

firmware versions

● Save/load configuration: the full IQOYA configuration can now be remotely downloaded/uploaded to/from IQOYA, in addition to be saved to the SD card. With previous firmware versions, it could only be saved to the SD card. The full configuration file is now a compressed file (.tar).

● Silence detection: silence detection on the decoded IP audio stream is now available, with silence criteria and signal criteria. An alarm is associated to it.

● Automatic disabling of a decoding priority upon silence detection. Each decoding priority can be configured to be automatically disabled upon silence detection in the decoded IP audio stream.

● GPIOs: Status of GPIs and GPOs is now displayed on a WEB page.

● GPO: It is now possible to define a status that each GPO takes when the IP audio stream is lost.

● GPO: a GPO can be used for tunneling or for signaling an alarm. If it is configured for both tunneling and alarming, it only reflects the alarming.

● A digital level can be adjusted for each decoding priority

● Possibility to load the configuration on the SD card when rebooting IQOYA.

What’s new on blue IQOYA *LINK and LINK/LE

● Audio source of the encoder can be a Livewire, AES67, or Ravenna IP audio stream.

● Audio destination of the decoder can be a Livewire, AES67, or Ravenna IP audio stream.

● Synchronization on a livewire clock, PTP clock

● Possibility to generate a PTP clock

● Synchronization on the AES/EBU input

● Possibility to configure an AES bit transparent transport (by using PTP between encoder and decoder)

What’s new in firmware 3.00?

● Four decoding priorities instead of three.

● New menu Preferences/Audio with three sub-menus: Audio in/out, Audio setup, Clock

● Possibility to receive an IP stream, and to transcode and stream it, thanks to the internal “Audio bus”. Receive section decodes the IP stream and sends the decoded audio to the internal “Audio bus”. Send section takes audio samples for the internal “Audio bus” and encodes them and streams over IP.

● Possibility to receive a Livewire stream and to encode and stream it, in standard Livewire mode (240 samples per frame).

● Possibility to decode an IP stream and to send the decoded audio as a Livewire

● Possibility to synchronize IQOYA on its AES/EBU input.

● Possibility to synchronize IQOYA on a network clock (PTP AES67, Livewire)

● Possibility of AES samples transparent transport between the encoder and the decoder without external GPS synchronization.

● Adjustable digital level on audio received on each decoding priority.

● New SNMP variables for allowing an SNMP supervisor to get the maximum jitter over a period of time.

Each decoding priority (1 and 2) has 3 new SNMP variables:

- max temporary jitter for primary stream : disReceiveSourceMetricsAutoResetJitterPrimary

- max temporary jitter for secondary stream : disReceiveSourceMetricsAutoResetJitterFEC

- max temporary jitter for primary& secondary streams : disReceiveSourceMetricsAutoResetJitter A GET on « disReceiveSourceMetricsAutoResetJitterPrimary » of priority 1 returns the max jitter for primary

stream of priority 1 since the last GET, and saves the other values for the priorities 1 and 2, and resets all the temporary jitters. The other values on both decoding priorities can be read (GET) right after the first GET. The counters evolve till the next GET on the temporary jitter for primary stream of priority 1.

● Persistent log file this feature requires the presence of an SDHC card in the unit. The log file is written at the same time in volatile memory and on the SDHC Card. In case the unit is powered OFF and ON, the log file is copied from SDcard to the volatile memory when the unit restarts, so that the log file is visible from the WEB interface with all the traces created before the power failure.

6 INSTALLATION

6.1 Connecting the IQOYA *LINK or IQOYA *LINK/LE

It is recommended to establish all connections before powering the device up. Before plugging the power cord, make sure it is not damaged: Just like for any other audio system, power the individual devices up following the audio path and power down in the

opposite direction. Do not allow anything to rest on the power cable. Keep the power cable away from where people could trip over it. After switching ON the codec, it takes about 30 seconds before it is operational.

We recommend that the first connection to the IQOYA codec is done on a LAN. The default IP address of the Eth0 interface (formerly IP audio) is 192.168.0.100. Make sure all other devices connected to this LAN are in the same subnet and have different IP addresses (this includes the PC from which you will connect to the IQOYA codec to configure it).

To connect the IQOYA codec to the LAN, connect the Ethernet cable to the RJ45 port labeled “IP AUDIO”.

Notes: The default IP address of the “Eth0” port (formerly “IP audio”) is 192.168.0.100. This port is enabled by default. The default IP address of the “Eth1” port (formerly “IP BACKUP / CONTROL”) is 192.168.1.100. This port is disabled by default.

IQOYA *LINK and IQOYA *LINK/LE embed a web server that enables you to control it through your favorite Internet browser.

6.2 Connecting the IQOYA *LINK or IQOYA *LINK/LE to an xDSL network

Like for any other IP equipment, it is highly recommended that IQOYA is not connected directly to the xDSL network. A router/firewall should be used to avoid attacks from “malware”.

7 REMOTE CONFIGURATION THROUGH HTML PAGES

7.1 Connecting to the IQOYA

Open a web browser and type in the address bar the IP address of the IQOYA codec in https mode and hit the ‘Enter’ key.

The WEB browser displays a message about security certificate. Select the option to continue with this WEB server. Enter the username and password. For a first configuration of the codec, use the default administrator login

(username: iqoya, password: iqoya).

You can now visualize the Web pages that enable you to configure the device.

7.2 WEB access rights

IQOYA *LINK and IQOYA *LINK /LE support three categories of users: Administrator, User, Read only

“Administrator” category

A user from the “Administrator” category has all the access rights on the WEB pages. The login to the embedded WEB server as “Administrator” is:

- username: iqoya

- default password: iqoya Password can only be modified when logged as Administrator.

“User” category

A user from the “User” category has limited access rights. “Write” access is limited to the audio parameters (audio format, source/target IP address and UDP port). The login to the embedded WEB server as “User” is:

- username: user

- default password: user Password can only be modified when logged as Administrator. Old password must be entered before entering the new one.

“Read-only” category

A user from the Read-only category only has “Read” access rights. He cannot modify a single parameter of the codec. The login to the embedded WEB server as “Read-only” is:

- username: guest

- default password: guest Password can only be modified when logged as Administrator. Old password must be entered before entering the new one.

7.3 Network parameters configuration

● Click on the ‘Preferences’ icon .

● Click on the “Network” menu

● Select the network interface you want to configure. IQOYA features two physical network interfaces (Eth0 and Eth1), and allows configuring two VLANs per interface

(typically a VLAN for IP audio data, and a VLAN for control). This complies with VLAN tagging IEEE 802.1q and

802.1p.

● Click on the ‘Configure’ button to be able to modify the parameters.

If you want to disable the network interface, select “Stopped” in the “Status” field. Status “running” means the network interface is enabled.

Make sure not to disable both interfaces Eth0 and Eth1, as you would loose the possibility to connect to the codec.

● Select the appropriate mode for the IP interface speed and transmission mode (Auto-negotiation, 10/100 Mbits/s,

half/full duplex).

● Enable or disable the DHCP mode, according to you network configuration. If DHCP mode is Off, enter a valid IP

address, the subnet mask, and if necessary the gateway and DNS IP addresses. Note that IQOYA takes into account one Gateway. It is then necessary to declare only one gateway; declare it on the appropriate network interface. In case a network interface is disabled, its gateway must be set to “none”.

● Confirm the settings by clicking on ‘Apply’.

Type the new IP address into the address bar of the browser to access the IQOYA *LINK again. Do the same for the “ETH1” network interface (IP Backup/Control) if required. By default ETH1 is disabled.

Make sure that Eth0 and Eth1 have IP addresses belonging to different subnets.

If you want to configure VLANs, select the VLAN from the “Network” menu (Eth0 VLAN 1, Eth0 VLAN 2, Eth1 VLAN 1, and Eth1 VLAN 2).

● Enable or disable the VLAN in the “Status” field.

● Enter the parameters of your VLAN: VLAN ID, VLAN priority, IP address of the equipment in this VLAN, and

subnet mask.

Make sure that Eth0, Eth1, Eth0.Vlan1, Eth0.Vlan2 ,Eth1.Vlan1, Eth1.Vlan1 have IP addresses belonging to different subnets.

● Confirm the settings by clicking on ‘Apply’.

From the “Preferences” page, you can view the IP routing table from the menu Network, IP routing.

● If you want to modify the routing table, first download the current table. Click on “Configure” and click on

“Download IP Table”.

● Edit the routing table (typically with Notepad). You may add your IP routes, as described in the downloaded file.

Note: In case you use both Eth0 and Eth1, do not declare two default gateways. Declare instead one default gateway for instance on Eth0, and routes on Eth1 (or vice versa).

● Save your modifications and upload the modified table by clicking on “Browse” and selecting it.

● Click on “Apply

”.

7.4 Services

7.4.1 NTP

7.4.1.1 Date and time synchronization

● Click on the ‘Preferences’

icon .

● Select Services, NTP

● Click on Configure

● Select “Yes” in “Service activation”, and enter the IP address of the NTP server in “Server IP address 1”.

You may enter a secondary NTP server IP address in “Server IP address 2”.

● Click on Apply.

Field “Service status” is set to “Running” when the IQOYA has synchronized its time with the NTP server. It is set to “Running, waiting for synchronization” when the synchronization with the NTP server fails.

7.4.1.2 Audio synchronization based on NTP clock (optional feature)

In the use case where several IQOYA units decode the stream of an IQOYA encoder, it is possible to synchronize the outputs of the decoders. This synchronization is based on the clock delivered by an NTP server. The accuracy of the synchronization depends on the NTP server stratum and on the network performance. The encoder and the decoders must all be configured to manage this audio synchronization based on NTP clock.

This audio synchronization mode based on NTP can be enabled form the Preferences page

, Services, NTP.

● Click on Configure

● Select “Yes” in “Service activation”, and enter the IP address of the NTP server in “Server IP address 1”. You may enter the IP address of a secondary NTP server in “Server IP address 2”.

● Select “Yes” in “Sync audio on NTP clock”

● Click on Apply.

At this point, IQOYA is set in mode where audio synchronization on NTP is allowed. It is then necessary to configure all the parameters. Specific parameters for audio synchronization on NTP are to be configured from the Send page for the encoder, and from the Receive page of the decoders which receive this stream.

Note that an IQOYA can at the same time generate a stream with NTP synchronization, and receive a stream with NTP synchronization.

Please refer to paragraph “Encoder output parameters” to generate a stream with audio synchronization based on NTP.

Please refer to paragraph “Decoder input parameters” to decode a stream with audio synchronization based on NTP.

7.4.2 SNMP

To be able to control and monitor IQOYA, and receive alarms from it via SNMP, it is necessary to enable the SNMP service.

Click on the ‘Preferences’ icon .

● Select Services, SNMP

● Click on ‘Configure”

● Select “Running” from the field “Status”.

● In case you need SNMP traps, enter the IP address(es) of the target SNMP supervisor(s). Up to 5 IP

addresses can be declared.

● It is also possible to change the Community strings for Read; write, and traps.

● Click on “Apply” to save your changes, or “Cancel” to discard them.

7.4.3 Publish/discover

This service is useful when IQOYA uses an AES67/RAVENNA input and/or output. It allows browsing through the AES67/RAVENNA streams available on the network for selecting one as an audio

source, or publishing the generated AES67/RAVENNA stream so that it can be discovered by other devices.

● Click on “Configure” to modify the parameters.

● Enable the service by selecting “Yes” in the field “Service activation”.

● Select the network interface connected to the ZAES67/RAVENNA network.

● Click on “Apply” to save the changes, or “Cancel” to discard the changes.

7.4.4 HTTP bandwidth limitation

In case the network bandwidth is limited and the IP audio stream takes almost all the network bandwidth, the HTTP traffic generated when accessing the WEB pages may disturb the IP audio frames transmission on the network, because the total bandwidth necessary for the IP audio stream plus HTTP traffic may exceed the available network bandwidth.

To avoid this problem, IQOYA offers the possibility to set a bandwidth limitation for the HTTP traffic. This is available from the Service menu, HTTPS. Bandwidth limitation: default value: ‘No’. Set this parameter to ‘Yes’ to define a bandwidth limitation for the HTTPS traffic. Maximum bit rate (kbit/s): enter here the maximum bit rate allowed for HTTP traffic from the IQOYA to the computer hosting the WEB browser. As a consequence, the HTTP upload traffic is also limited, and it takes longer to display the WEB pages. The lower the ‘Maximum bit rate’ value, the slower the WEB pages display.

Note: when loading all the WEB page (typically first access to the WEB page), there may be an additional peak of

HTTP traffic exceeding the limitation of +25%. As a consequence, it is recommended to lower the maximum bit rate value to take into account this peak.

Example:

Network bandwidth limited to 2 Mbits/s Audio format: PCM stereo 16 bits 48 kHz FEC: +10% IP audio bit rate (including FEC): 1 834 800 bits/s Maximum value to be set for parameter ‘Maximum bit rate’: 130 kbits/s

7.4.5 FTP

Enable this service to be able to manage to manage the sound files and playlist files on the SD card, and for downloading the MIB file.

● Click on “Configure” to modify the parameters.

● Enable the service by selecting “Yes” in the field “Service activation”.

● If you want to limit the FTP transfer speed, enter a value in kbps in the field “Bandwidth limitation”.

● For the “Guest FTP Access” parameters, see section “Authorizing a user to upload playlists to the SD card via

FTP”

● Click on “Apply” to save the changes, or “Cancel” to discard the changes.

7.5 Global audio parameters configuration

Once the network parameters are configured, it is necessary to configure the global audio parameters, the transmission parameters for streaming to one or several destinations, and/or the reception parameters. Either the transmitter (Send) or the receiver (Receive) section has to be configured for a unidirectional connection (half duplex). Both the transmitter and the receiver sections have to be configured for a full-duplex connection.

Global audio parameters are configurable from the “Preferences”

page , in “Audio”

menu.

Audio clock

IQOYA supports the following modes for the clock:

Clock source

PTP

Internal

PTP Master mode possible

AESin

PTP Master mode possible

PTP AES67

Livewire

The clock source is the clock that gives the sampling frequency of IQOYA. Select “Audio Clock”to access the clock settings.

IQOYA clock source can be the following.

7.5.1.1 Internal clock

● Clock source: to be set to “Internal”

● Master clock: Set this parameter to “PTP Master” in case IQOYA is used as an encoder and decoder(s)

have to be synchronized via PTP (typical use case: AES bit trasparency). Set it to “None” otherwise.

● Sampling frequency: it defines the working sampling frequency of IQOYA. Note that received and generated IP streams can carry audio at a different sampling frequency (in which case a high quality hardware sampling frequency change is applied). When sampling frequency is set to 48 kHz, IP streams can be at 48 kHz, 32 kHz, 16 kHz (G722), and 8 kHz (G711). Note that 44.1 kHz is allowed for a HTTP stream. When sampling frequency is set to 44.1 kHz, IP streams must be at 44.1 kHz or 22.05 kHz.

● Activate AES IN SRC: to be set to “Yes” in case the AES/EBU input is selected as audio source from the “Audio” menu, and clock source is set to internal.

7.5.1.2 Clock from the AES/EBU input (available on IQOYA units with blue front

panel)

● Network clock: to be set to “AES in”.

● Master clock: Set this parameter to “PTP Master” in case IQOYA is used as an encoder and decoder(s) have to be synchronized via PTP (typical use case: AES bit trasparency). Set it to “None” otherwise.

● Sampling frequency: select the value of the sampling clock that matches the AES/EBU input sampling clock.

● Activate AES IN SRC: to be set to “No”.

7.5.1.3 Livewire clock (available on IQOYA units with blue front panel)

This external Livewire slave clock is typically to be selected when IQOYA is used for:

- encoding and streaming audio samples coming from a low latency (48 samples per packet = 1ms) or

Standard (240 samples per packet = 5ms) Livewire stream.

- or decoding an IP audio stream to a Livewire stream.

Note that once the livewire network configuration is applied, this page should display values and bar graphs about the clock.

● Sampling frequency: select the value of the sampling clock.

● Activate AES IN SRC: may be set to “yes” if the AES/EBU input is the audio source and it is not synchronous of the Livewire clock. To be set to “No” otherwise.

● Network interface: select the Eth interface connected to the Livewire network.

7.5.1.4 AES67 PTP clock (available on IQOYA units with blue front panel)

This external clock is typically to be selected when IQOYA is used for:

- encoding and streaming audio samples coming from a RAVENNA/AES67 stream

- or decoding an IP audio stream to a RAVENNA/AES67 stream.

● Clock source: set to PTP AES67 (slave)

● Sampling frequency: select the value of the sampling clock.

PTP parameters must then be configured.

● Transport: Unicast or multicast

● Domain number: This MUST be set to match the domain number of the related PTP Grand Master.

● Mechanism: Syntonized, End to End (Request responses E2E) or Peer to Peer (P2P). Syntonized means that IQOYA’s clock is the same as the Grand master PTP, but they are not synchronous (delay between the two clocks).

● Synchronous clock is obtained thanks to E2E or P2P modes, which serve to compensate the delay between Grand master PTP clock and IQOYA. E2E is a more universal setting (it consists of requests and answers between the node (IQOYA) and the grand master PTP clock unit). P2P provides higher clock sync precision but requires full PTP support from all participating switches (between IQOYA and related clock master.) In case the PTP clock is generated by an IQOYA, the PTP mechanism must be the same as in the IQOYA master: syntonized.

● Network interface: Select the network interface that receives the PTP clock.

● Multicast TTL: Time To Live value of the multicast PTP frames. This value must be set according to the number of routers the frames have to cross. If the value is >0, each router decreases it before forwarding the frame. When a router finds the TTL value 0, it stops the frame which then does not continue its route.IGMPv3 filtering mode: Allows filtering PTP grand master clock sources: IP addresses of PTP grand master units can be included or excluded. Set this value to “No” to disable the source address filtering.

● Slave IP address: Unused in PTP AES67 Slave mode.

● DSCP: The QoS (Quality of Service) value for PTP traffic (0-63). It is recommended to assign a value which is treated as highest priority level in the network. Default is “Expedited forwarding (EF)”.

● Sync interval: In Slave mode, this MUST be set to match the Sync Interval of the related PTP master clock. In Master mode, this determines the desired Sync Interval.

7.5.1.5 Clock settings for AES bit transparent transport

IQOYA allows for transporting an AES/EBU signal from an encoder unit to one or several decoders unit in PCM format without modifying the audio samples, and with transmission of the C and U information bits of the AES/EBU frames. In this way, audio samples remain unchanged after the transport between the encoder and the decoder(s). There are two possible ways of doing it with IQOYA:

● By synchronizing IQOYA units on AES clocks derived from the same master clock (example: AES clocks derived from GPS)

● By synchronizing the IQOYA decoders to the IQOYA encoder through a PTP clock generated by this latter.

The following describes the PTP synchronization mode. Set the IQOYA encoder in “PTP master” mode, and the IQOYA decoders in “PTP slave” mode.

The PTP clock delivered by IQOYA can be unicast or multicast (multicast must be supported on the network).

For this configuration, it is necessary to use a network link with low jitter and with possibly QoS applied to the PTP frames, otherwise PTP synchronisation might be unusable.
