Application Example 1

    The IDM VDT1000 bidirectional audio/video codec transmission device is designed to adapt to telecommunications E1 (2M port) transmission channels, employing H.264 compression with powerful real-time image capture and compression capabilities. The IDM-VDT1000 compresses and multiplexes input video, audio, and data into a 2M-rate PCM stream, which is delivered to the transmission equipment via the E1 interface for long-distance transmission, meeting the requirements of remote video surveillance, video conferencing, and other systems, while improving the utilization of E1 line resources in private networks/SDH networks. It also provides RS232/485 serial data communication ports to meet the needs of remote video surveillance, video conferencing, and other systems. All interfaces comply with international standards and are suitable for various working environments.
