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). Ideally suited for use with a laptop, but convenient with a standard PC or server too.

Features:

•  USB powered – no power supply required
•  Independent operation of DVB-ASI / SDI  input and output:
–  Full-duplex: combined bit-rate 0-160 MBps
–  Half-duplex: DVB-ASI and SDI bit-rate range 0-214 MBps
•  16-Mbytes local hardware buffer for sustained real-time streaming
•  The DTU-245-SXP comes with StreamXpert for Real-time analysis, monitoring and recording of MPEG-2 transport streams; and StreamXpress for ASI/SDI play out
•  The DTU-245-SY-SXP includes all software of the DTU-245-SXP plus  SdEye for SDI analysis and monitoring
