The DCH-5500EC is a high performance MPEG2 and H.264 HD encoder. It has a wide range of digital/ analog video and audio inputs: CVBS, HD-SDI, HDMI, YPbPr, SPDIF, AES/EBU and XLR balance Audio. Two pairs of stereo audios can be encoded using AAC, MPEG-1 layer II encoding or pass-through the audio data. The encoded video and audio transport stream is available from its TS_over_IP and ASI outputs. With this full range audio and video format compatibility, the DCH-5500EC addresses versatile MPEG2 and H.264 encoding market in the bandwidth scale from 250Kb/s to 25Mb/s.
