DVB ASI Multiplexer(8in2)

Outline
Multiplexer is a digital broadcasting TV system TS stream re-multiplexer. multiplexer combines several single-programs or multiple-programs, which are compressed, coded, and multiplexed according to customer request by head-end, into single transport stream. Besides, it is also able to interpolate EPG (Electronic Program Guide), CA (Conditional Access) and digital broadcasting etc. Maximally, it can synchronal multiplex 8 route input code streams, and support ASI interface. The code rate of input code stream is maximally up to 270Mbps, while code rate of four separate outputs code stream is maximally up to 108Mbps. Through auxiliary data input channel, Its dimension is standard 1U case. By watching the LCD display on the front panel, user can finish the setting of auto-running of this device.
Features
ü   Multiplex 8 inputs (ASI) SPTS or MPTS, multilevel multiplexing is available
ü   Dual independent TS output
ü   Input date bit rate: 216Mbps(max)/channel
ü   Output bit rate: 2Mbps~120Mbps(tunable), available bit rate is up to 120Mbps
ü   PID filtering and PID re-setting, the user could add , delete the program as they wanted, and mapping the PID of selected program automatically. Support user-defined program’s PID and input through channel
ü   ETHERNET interface, it could carry out the parameters setup and supervision from remote via network management unit.
