Outline
COL5181B MPEG2 SUPER Encoder (8 in 1), the powerful and stable equipment is very popular in the digital broadcast word, because it can be used in so many solutions to reduce a lot of the cost of the total system. COL5181B is a high density, high performance video processing platform. It's powerful multifunction and stable performance made it suitable for versatile circumstance and can be deployed on the VOD, real time CATV or satellite head end.
COL5181B integrates 8 channel encoder and TS multiplexer in a compact 1RU form, ideal for head end deployment or head end enlargement. Lower bit rates MPEG2 SUPER SD encoding, support up to 28 channel program multiplexing makes you cast more programs on the limited bandwidth. Human design, the friendly operating network software makes you control the equipment easily.
