The IG­VirtualVoice System is a platform that enables centralized management, generation and transmission of audio messages to different sites using Voice over IP (VoIP) techniques. It is specifically focused to Public Address services where the geographical distribution for audio broadcasting is the main constraint. In this area, it offers the following advantages over equivalent analog solutions: • It does not need a specific communications infrastructure: the system can be easily integrated into a TCP / IP communications infrastructure, regardless of technology used (Ethernet, ATM, Wi­Fi, etc.). Then with a standard IP network (Multiservice IP network), it can provide any type of sound communication between the Service Center and the audio broadcasting point. • Different audio sources: because it is a based on VoIP and the “state of the art” in digital audio technology, the system supports live audio, pre­recorded audio and text­to­speech messages. • Open system: standard protocols are exclusively used for interconnecting every element of the system (SIP and Audio Streaming). • Analog platform independent: IG­VirtualVoice system is an independent element from analog stage (amplifiers and speakers) and it has standard audio interfaces, so any analog equipment manufacturer can be easily integrated. • Modular and scalable system, with high reliability and availability.

Technical Specifications (I)
System Management: • Broadcasting of prerecorded messages, live audio or text­to­speech, allowing multiple methods for selecting the destination (per player or group of players, per audio outputs, priority, date and time, etc.). • Standard­based solution for voice over IP transmission (SIP G.711 codec) and file transfer (TFTP ­ Trivial File Transfer Protocol) which allows hardware / software integration from different vendors in the global solution. • Every player offers up to 3 independent audio unbalanced outputs at 0dBm, compliant with the input signals specifications from standard analog audio amplifier systems. • It integrates a mechanism for audio message prioritization that allows the interaction of different sources simultaneously tries to access to the same broadcasting player or area, ensuring that the most critical message is always played in the first place. • Every player can autonomously operate in terms of playing prerecorded messages, live audio or text­to­ speech, which allows support a high service availability, as well as working when a failure condition appears in the IP network. • Integrable with other external systems to allow for automatic message broadcast due to external events (for example, alarms). • Web interface for central servers and audio players administration. • User interface based on Windows operating system, capable to be embedded in thrid­party applicactions.

Supported Languages: • Text to speech engines in several languages: Spanish, French, German, Italian and Portuguese. • Male and female voices. • Standard quality (by default in the system) or premium quality voice codecs (optional: 1 license per player). Scalability: • Works in any TCP / IP network without the need a dedicated network for the service, reducing the cost and deployment time of the system (multiservice network). Developed System by InfoGLOBAL: • Can be performed any specified modification or extension in the firmware by customer request in order to completely adapt the product to any specific environmental needs.

The Public Address Server (IG­VV­GEME) is the equipment where the service intelligence is located. It is an embedded server with the management application with additional features for platform control and management: • Equipment Inventory: all elements of the system (players and software clients) should be registered in GEME server and refresh it periodically. In this way, GEME server will know at all times with what equipment are available. • Registration of prerecorded and text­to­speech messages: GEME server records and maintain the master copy of prerecorded and text messages. Any change from an operator launchs a process for remotely update all the players. • Service Management: GEME server receives requests for message addressing from operators and is responsible for distributing them to the players, managing priority events and available resources. • Activity reports: GEME server receives requests from operators as well as activity reports form players, allowing to generate statistics from the platform. This information is stored in a logging database and it is available for querying. • Failure reports: GEME continuously receives information from players that report their own state, the managed audio amplifiers and speaker lines (if available) . This information is stored in a logging database and it is available for querying.

The Public­Address Player (IG­CRAYAMP3) is the system that is located in the remote location closest to the analog audio equipment (amplifiers), following the service architecture in any environment. This equipment supports the audio broadcasting features in the location: • Definition of multiple broadcasting zones: CRAYAMP has 3 independent audio outputs to connect the analog audio amplifiers, such as every one covers a certain area or zone, and therefore may be defined, managed and operated independently in the system when voice messages must to be broadcasted. • Broadcast Execution: CRAYAMP receives requests for audio broadcasting from GEME server and its priority, reporting the state, as well as at any time is able to inform to GEME about the it resources availability. • Audio decoding: CRAYAMP decodes the broadcasted live audio, pre­recorded and text to speech messages, translating them into analog audio so they can be processed to every amplifier connected to every audio output. • Analog Equipment Management: CRAYAMP can manage the external amplifier (if available) through several different methods (IP, serial, I/O relays, etc.).
