Introduction
The Visual Circuits ReelTime 4 and the 4ReelTime Pro boards are
PCI bus boards that can play back up to four MPEG2 or MPEG1
video and audio files simultaneously. The ReelTime 4 supports
composite video, S-video, or interlaced RGBS video (Red, Green,
Blue, with combined H/V sync). This form of RGB video cannot
be displayed on a standard computer VGA monitor. There is CD
quality stereo audio output for each channel.
The 4ReelTime Pro supports composite video and optional S-video
output. The ReelTime 4 board has replaced the 4ReelTime Pro,
offering the same performance with increased functionality.
The ReelTime 4, in addition to adding RGB quality video output,
now provides software controlled volume adjustment on the
baseboard. (Volume control previously required an additional
audio or genlock card.) The ReelTime 4 supports the new RT
Daughter card for genlocking. The RT Daughter card also offers
an onboard blackburst generator. (See RT Daughter document for
details.)
Each board is designed to operate as a PCI bus master. This means
that once the software tells the board where to retrieve the MPEG
data from, the board will retrieve and route the data to the
appropriate channel with minimal CPU use. This feature allows
for multiple boards to run concurrently with smooth multi-channel
video and audio playback.
NOTE
ReelTime 4 and 4ReelTime Pro boards cannot
be mixed in the same server.
