Encoder Plus
The iPlex offers a Real-Time MPEG Encoder Plus (RTME Plus) submodule. This
encoder supports two stereo channels of audio for either MPEG-1 Layer II or
Dolby Digital (AC-3) audio. The audio source can be any of the following types:
Unbalanced, Balanced, AES or Embedded SDI. The encoder supports analog and
digital video sources. For an analog video signal, you can configure the encoder
input as S-Video or composite video. Alternately, the encoder can receive digital
video input through the Serial Digital Interface (SDI). The encoder is capable of
extracting embedded audio from the SDI input.
