| Audio Channels |
Note When the decoder is licensed for one channel only, it mirrors the decoded stream to all interfaces and supports up to eight (8) channel pairs of AAC-LC or AC-3 audio decoding for a stream. MPEG-2 TS streams received containing AC-3 audio will be down-mixed to a stereo pair for output on the HDMI and SDI interface. See “Audio Channel Details/Breakout” below. |
