Ambe Codec Software

Net-2000™ Voice Codec. By incorporating DVSI vocoder software with Ethernet network connectivity the Net-2000™ VCU is ideal. Net-2000™ AMBE. Open Source DSTAR Voice -- Codec2: from KE7HQY on June 6, 2010 The DSTAR protocol is open and freely available, developed by the Japanese Amateur Radio League (JARL). However, the AMBE voice encoding scheme currently used by the DSTAR protocol is not open, rather it is patented by DVSI, Inc.

Ultimate Unwrap 3d Pro Rapidshare Movies. 6 kbps Introduction The Net-2000™ Voice Codec Unit (VCU) represents the latest advancement in voice compression technology offered by Digital Voice Systems, Inc. The Net-2000™ VCU hardware incorporates DVSI's patented vocoder software for voice compression applications geared toward Ethernet-based and wireless communication systems. The Net-2000™ VCU is designed for flexibility in integration, making it well-suited for a variety of other OEM digital-communication applications, including Voice Over Internet Protocol (VoIP), wireless telephony and voice-monitoring / recording products. All Net-2000™ VCU models integrate an UDP/IP packet protocol for remote access and control. The 10Base-T Ethernet connection on the Net-2000™ VCU allows full-duplex real-time or half-duplex non-real-time voice compression applications over a Local Area Network (LAN). Using the LAN, two Net-2000™VCUs (of the same models) can communicate to create a Voice Over Internet Protocol (VOIP) Ethernet-based vocoder communication system.

Communicating between two Net-2000™ VCUs is as easy as entering the IP address (or host name) of the Net-2000™ VCU units, selecting the desired voice interface and the Full-Rate or Half-Rate Vocoder mode. When two Net-2000™VCUs communicate, each converts the input analog speech into digital speech samples, encodes the speech using the selected vocoder rate and sends the compressed bit stream out as UDP/IP packets over the Ethernet interface. Simultaneously, the compressed bit stream of UDP packets from the other Net-2000™ VCU are read from the Ethernet interface and decoded back into digital speech samples. The decoded samples are converted back into analog speech via the AIC-10 codec whose output is sent to both the handset and line-level output connections. Since the channel data is a packet-based UDP Ethernet protocol, users can develop their own customized controls and user interfaces so that the Net-2000™ VCU can fit into an endless array of applications. Digital Connectivity The UDP/IP connection can also be used to encode/decode files from a PC, or other UDP/IP device making the Net-2000™ VCU ideal for compressed-voice storage applications or non-real-time testing. Alternatively, the Net-2000™ VCU can loop back the VOIP digital data to itself for voice monitoring and evaluation applications.
