MPEG-4 Encoder (4 in 1), digital TV headend.

MPEG-4 Encoder 1. 4 channels video interfaces(CVBS) 2. 4 channels imbalance audio interface output 3. 2 ASI output

COL5141B MPEG-4 Encoder

Outline

COL5141B 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 multiplexingMuch less bit rate Compared with fujitsu solution, under the same image quality , this equipment can reduce the bit rate at least 30%Input image proportion of height and length support 4:3 and 16:9 output imageTow Video encoding format support MPEG2 and MPEG4 coding formatMultiple audio standardMore powerful adjustment function on picture quality parameters   Support picture sharpness adjustable, VBR and CBR variableMore stale network performance adopting Marwell 6218 as CPU chip, supporting connecting with Hub.SDT,NIT settingOutput code rate adjustable, flexible in operation4 channels video interfaces(CVBS)4 channels imbalance audio interface output2 channels ASI output
