8) What is the maximum MPEG2 data-rate? Up to 40Mbps.
9) Can HD-Connect LE™ decode other MPEG streams, besides HDV? Yes,
the board supports most of the ATSC (ISO/IEC 13818-2) streams, but is
limited to bit rates below 40Mbps.
10) Does the HD-Connect LE™ support DV? No, this is a likely feature for a
future box in the HD-Connect family.
11) What is the data rate of HDV? 720p HDV is approximately 19Mbps, 1080i
is 25Mbps.
12) What is the recommended workflow using HD-Connect LE™? Use HD-
Connect LE™ to convert from HDV to HD/SD-SDI via firewire. Connect
the HD-SDI output to an HD/SD-SDI capture card. Capture the video and
audio either uncompressed or using the I-Frame CODEC such as
DVCProHD or DNxHD. You can control the HDV deck by connecting the
RS-422 from your capture card to the LE box.
13) I edit native HDV on my laptop, how do I monitor HDV and master to
tape? Connect your HD-Connect LE™ to your firewire port and do a
“Print to Tape”. You can monitor the video via the composite output (when
scaled down to SD) or an analog component or SDI monitor. Using the
upcoming HD-Connect LE™ 1394
→
RS-422 control, you can use this
same setup to output to a BetaCam, DigiBeta, or HD-CAM deck.
