DH-ENC     MPEG-2 Compact encoder

DH-ENC MPEG-2 compact encoder, which is up to DVB standard, encodes A/V signals of analogue TV into MPEG-2 real time transporting stream(TS). The original analog TV signals can be PAL/ NTSC. Different output interface, for example,ASI,E1,E3,or Ds3 etc, could be fitted in DH-ENC for different networks such as HFC,MMDS,8GHz microwave system, PSTN, SDH. Therefore...

DH-MMDS-TX     Digital MMDS Transmitter

DH-MMDS-TX  is a high-quality broad band digital MMDS transmitter, operating without power combiner &wave guide with single channel or multi-channels output. It is well known that analogue MMDS system can transmit 23 channels (8MHz wide each), so when MMDS is used for digital transmitting, much more channels can be transmitted since each 8MHz width can take 4-6 MPEG-2TV program or over 20 MPEG-1 audio programs. Owing to the very low LO phase noise, analogue signal transmitting is compatible with DH-MMDS-TX...
