Lowest Price but Good Quality for MPEG2/MPEG4 IP Encoder (4 in1), CATV Headend COL5141BP

Specifications

COL5141BP Encoder adopts minimum code rate compress technology, it mainly used in the ground digital TV systems. Powerful image preprocessing ability to maximize remove redundant information. It completely complies MPEG-2 standard, and MPEG-4 and it has high compatibility. Its dimension is 1U standard case. By watching the LCD display on the front panel, user can finish the setting of auto-ranning of this machine.

Features 

• With one ASI input the equipment has two function, encoding and multiplexing
