ADV-8124 is high quality multi-channel professional video/audio encoder with multiplexer.     It has 8/16/24 encoding channels with CVBS video and unbalanced audio inputs.

It supports MPEG-4 AVC/H.264 video encoding and MPEG1 Layer II Audio encoding.
ADV-8124 has modular design, up to 3 standalone modules (24 channels) can be installed.

Each module multiplexes 8 encoded TS to generate a MPTS output through GE output port.
Each module also can output one MPTS through 2 ASI output ports.

High integration and cost-effective design make this device widely used in variety of digital distribution systems such as CATV digital head-end, satellite and terrestrial digital TV, surveillance, etc.
