Sensoray 614 - Manual (Page 5)

Introduction
Model 614 is a PCI version of MPEG video and/or audio capture device. It captures video and/or
audio from a standard NTSC/PAL analog video source optional with stereo or monochrome audio
source into one of following compressed MPEG streams: MPEG1, MPEG2, MPEG4, H.263, or
MJPEG. It also supports capturing raw frames from NTSC/PAL video source.
The capturing frame rate is up to 30 fps for NTSC and 25 fps for PAL. Capturing resolution could
be chosen from followings: D1.N (NTSC), D1.P (PAL), VGA, QVGA, QQVGA, SIF, 2SIF, 4SIF, CIF,
QCIF, SQCIF, 4CIF.
Captured MPEG-1/2/4/MJPEG video can be annotated with up to 8 windows/fields of caption
overlay. Hardware-wise, it’s implemented between raw capturing and MPEG/MJPEG compression,
on bitmap block base. Therefore, both text characters (for text caption overlay) and bitmap-blocks
(for image overlay) could be supported. Up to 64 characters or bitmap-blocks can be filled into one
window/field. There are four scales available for being chosen for each window/field to size the
overlay. The caption overlay can be chosen in transparent or non-transparent.
A single +5V power supply through PCI bus is required to power the board.
