Prody's New Nereus Multi IP Codec

     

Nereus is a Multi IP Codec in a 3U rack, which can house up to 14 IP audio modules. These IP audio modules are based on ProntoNet, so it offers the possibility to extend the number of audio signals over IP provided by ProntoNet. It supports all the main features of ProntoNet when working over IP, and inherits all the key features from the devopment of ProntoNet, such us widest range of audio compression modes, stability, flexibility and easiness to use.

Its most important features are based on ProntoNet:

   · IP Multicast and Unicast audio streaming transmission/reception.

   · The Ethernet port is used for audio and control. 

   · Each IP Module offers fully TCP/UDP/IP connectivity via a 10Base-T/100BaseTX Ethernet port.

   · Dolby E transmission/reception over IP (by using AES/EBU I/O in transparent mode).

   ·Most important industry-standard algorithms: PCM,G722,MPEG1/2 Layer II/III, MPEG2/4 AAC LC, MPEG4 AAC LD, apt-X(Standard and Enhanced 16,20 & 24 bits).

   ·Automatic detection of the encoding mode used by the remote unit.

   · A redundant AC power supply is available as an option.

   · Up to seven user configurable general purpose input-outputs (open-collector signals, RJ45 connector).

 

 Streaming advance features:

   - Jitter correction buffer.

   - The unit automatically adjusts in synchronisation with the transmitter site rate.

   - The frame size is user configurable.

   - The codec provides a test tool which allows the user to check the bandwidth, delay and jitter in the IP connection.

   · Local or remotely (TCP/IP) upgrading of one or several units at once using the same utility.

   · Alarms: Real Time alarms management through SNMP traps and e-mails .

PRODYs provide equipment for the broadcast and communications markets that include:

 

 

PRODY'S PORTANET

Portanet is based on the ProntoNet IP & ISDN dual audio codec. Portanet can send and receive simultaneouly via IP thorugh its Ethernet port (10/100BaseTX), and can connect to ISDN codecs through Its built in 1-BRI terminal adapter, which supports U and S/T interfaces and the following ISDN protocols: EISDN, AT5ESS, DMS100 and NAT1.
Portanet comes fitted with the widest range of industry-standard coding algorithms: G711, G722, MPEG 1/2 Layer II/III, MPEG2/4 AAC LC, MPEG4 AAC LD, Apt-X and PCM (uncompressed linear audio over IP), which offers great flexibility by enabling compatibility with connections to third party codecs. Like ProntoNet, Portanet can automatically detect the calling codec and synchronize to It.
Portanet can be controlled from Its top panel, through a large, easy to use, navigate menu display, or via remote control, through Its embedded Web Page, or thorugh the ProdysControl application, from which one can control all the Prodys audio codecs (ProntoNet, Pronto2/3, Kronos E1/T1 Multiplexer, PortaNet...).

Specifications:
AUDIO
·4 XLR balanced mic inputs (switchable for mic,line and 48V. phantom power) each with independent level control.
·Channel assignament (main or talkback) buttons for each input.
·Input level indicator for program channel.
·Limiter after program mixer input.
·Tree 6.35mm jack headphone outputs with independent channel (local/return) and level controls. The headphone mix funtion let users monitor local, return audio or a mix of the two for both, the main program and the talkback program.
·Two XLR male, electronically balanced outputs, as auxiliary outputs. These outputs are totally configurable, so that each one can be assigned to monitor send, receive audio or a mix of them, for both the main and the talkback program.

ENCODING
· Many industry-standard compression modes: G711, G722, MPEG 1/2 Layer II/III, MPEG2/4 AAC LC & MPEG4 AAC LD , Apt-X standard and enhanced, and PCM (uncompressed linear audio) for IP networks of sufficient bandwidth.

COMMUNICATIONS
·Built-in 1-BRI ISDN terminal adapter. S/T and U interfaces. Protocols: EISDN, DMS100, NAT1 and AT5ESS.
·Ethernet 10/100BaseTX interface: Full industry-standard TCP/UDP/IP connectivity. No special networking required. The following protocols are provided:
· DHCP: IP address auto configuration.
· RIP2: Internal/Alias IP addresses can be assigned.
· SNTP: Clock synchronization.
· SNMP: Remote monitoring over SNMP protocol.
· HTTP: An embedded Web server allows the user to monitor/configure the unit from a Web Browser. An ActiveX dynamic Web Page offers full real time monitoring.
· IGMP: This protocol deals with Multicast traffic.
· ICMP: IP control protocol.

Portanet supports both unicast and multicast IP audio streaming connections.

·Streaming advance features:
· Jitter correction buffer. This adjustable buffer avoids audio dropouts compensating for up to 500mS of jitter in the IP connection.
· The unit automatically adjusts in synchronisation with the transmitter site rate, to give a constant delay in IP communications.
· The codec provides a test tool which allows the user to check the bandwidth, delay and jitter in the IP connection. This information can be used to adjust the streaming parameters and so, to obtain the best-quality in the real-time audio reception.
Local or remotely (TCP/IP) upgrading of one or several units at once using the same utility, which is also compatible with ProntoNet units. Factory sofware updates can be downloaded

AUXILIARY DATA
Two RS232 Ancillaty Data ports, for data transmission, such as RDS.
GPIO
2-GPIOs gives the possibility to connect to automation systems: Remote contact closure to send control signal with the compressed bit stream.

ALARMS
Real Time alarms management through SNMP traps.
The alarms are saved in non-volatile memory. It is possible to have an historical log of events even if the unit was disconnected from the network.

BACKUP
Integral backup feature to assure program continuity, in the event of a failure of the main line. ISDN can be used as a back line line in the event of a failure of the IP or X21 lines.

 

PRODY'S PRONTO 3

 

Pronto ISDN 3 completes the PRODYS audio codecs family improving the features provided in previous models. Based on the Motorola 56309 DSP, Pronto ISDN 3 extends its performance possibilities as dual audio codec and supports Layer III amongst its coding algorithms. Its most important features are:    ·ISDN universal terminal adapter (S0 ) and X21 interface.    ·Analog or digital audio (AES/EBU). The AES/EBU interface provides input for external clock.    ·Dual operation (two fully independent communications) in G711, G722 and MPEG Layer II/III MONO 64 Kbps.    ·Independent operating encoding and decoding modes.    ·Automatic detection of the encoding mode used by the remote unit.    ·Compatibility in all modes (G722 and MPEG Layer II/III) with CCS and TELOS.    ·Auxiliary data in MPEG Layer II/III modes.    ·Electrical echo canceller and multiplex (conferencing) in G711. A conventional analogue telephone connected to the front panel of the unit allows communications to be established or received remotely and pass the call to the programme, on hold or on air, as usual with hybrids for the basic telephone network. When the G722 mode is selected, the unit allows high quality voice communications via the ISDN network, with an advantage over other audio encoding systems of a low delay. It also includes a digital audio I/0 AES/EBU signal and a connector for transmitting and receiving auxiliary data simultaneously with the MPEG audio. Pronto3 supports TA and even a X21 port for connecting the equipment to other digital communication networks (dedicated networks, satellite communications etc.) EXTERNAL TELEPHONE: The Prontos also features de ability, accessed through a simple front panel menu, to remote control the unit with a standard analogue telephone (connected to the RJ11 socket on the front panel) using the DTMF (multifrequency) tones generated by the dial pad. The same telephone can also replace an audio I/O channel in G711/G722 modes to act, for example, as a talkback system.
