The ASI-310 convert MPEG-2 transport streams between DVB-ASI and SMPTE 310M formats. ASI-310 converter offers number of unique features to ease integration into environment. It can simultaneously convert ASI-to-310 and 310-to-ASI. The 310 output can be frequency-locked to reference 310 input or high-stability on-board temperature-compensated crystal oscillator can be used. The bit rate is user-selectable (19.392658 or 38.785316Mb/s) as is PCR re-stamping of 310 output stream.Wide range of ASI input rates can be converted to 310 by adding or deleting null packets as needed to maintain the exact output data rate. GPI/O outputs can be used to signal error conditions such as loss of video and excessive ASI input rate.
