Product Overview
PR-3228B 8 in 1 (PR-3224B 4 in 1) MPEG-2/H.264 SD Encoder is our professional SD audio & video encoding and multiplexing device with powerful functionality. It has 8/4 independent channels of unbalanced audio & CVBS video input interfaces or SD-SDI input interfaces. The device supports MPEG-2 and H.264 video encoding and MPEG-1 Audio layer 2, LC-AAC, HE-AAC and DD AC3 (optional) audio encoding. In addition, it has an ASI input and can multiplex the input TS with the 8/4 encoded SPTS to generate a MPTS output.
