Overview

ISDN AUDIO CODEC/RECORDER/EDITOR

Opticodec 7000 is a portable audio recorder that can edit and also transmit live. It contains an ISO/MPEG Layer II and Layer III compliant CODEC for use with ISDN. Also included are G.722 7kHz and G.711 telephone modes. Opticodec reduces the bit-rate required to transmit and receive audio between the audio source and the remote receiver location. The ISDN interface provides support for ISDN telephones, eliminating the requirement for additional 1MB service for voice communication. Opticodec 7000 includes a digital audio recorder and digital audio editor for ISO/MPEG Layer II, and transmits ISO/MPEG Layer III over ISDN in a very small, lightweight battery or AC powered package.

Opticodec 7000 is aimed at mobile radio and television broadcast, voice, music, recording and production studio, and broadcast news gathering applications.
