DTU-245 - DekTec USB-2 ASI / SD-SDI Input+Output Adapter

Description

Convenient, compact USB adapter that can be used to capture and generate MPEG-2 transport streams (DVB-ASI) and uncompressed serial digital video (SDI).

Features:

•  USB powered – no power supply required
•  Independent operation of DVB-ASI / SDI  input and output:
-  Full-duplex: maximum combined bit-rate of 160 MBps
-  Half-duplex: Full DVB-ASI and SDI bit-rate range
•  16-Mbytes local hardware buffer for sustained real-time streaming
•  The DTU-245-SDP comes with DtGrabber+ for advanced recording, DtTV for viewing TV services and StreamXpress         for ASI/SDI play out
•  The DTU-245-SY-SXP includes all software of the DTU-245-SDP plus DekTec’s renowned StreamXpert software             for MPEG-2 analysis and monitoring and SdEye for SDI analysis and monitoring
