Sensoray 2263 - Manual (Page 5)

Introduction
Model 2263 is an audio/video capture and playback device. It supports a multitude of
analog and digital sources, ranging from SD composite (NTSC, PAL) to full HD digital
(DVI, 1080i).
Model 2263 outputs simultaneous compressed and low-latency uncompressed (preview)
video streams. In case of HD input source the preview stream is scaled down and the
frame rate may be decimated to fit into the bandwidth available with USB 2.0.
For compressed streams the choice of H.264 or MJPEG video compression types is
available. Compression type, target bitrate and resolution are controlled with provided
API.
Model 2263 captures audio from a stereo line input or audio embedded in the digital
input stream. Output audio formats are uncompressed PCM or AAC.
The output containers are mp4, transport stream (.TS), and AVI.
The board can perform as a decoder for all supported compression types (decoding is
guaranteed only for streams captured with model 2263).
The board implements USB 2.0 high speed interface which also provides power for the
device. A “Y” USB cable is provided to satisfy power requirements.
Model 2263 is available in the enclosure (2263S), or as an OEM board (2263).
System Requirements
A basic model 2263 application (capture of a compressed stream and preview of the
uncompressed) will work on a Pentium III class processor since no significant
processing is required from the host . A high speed USB 2.0 port is required. A second
USB port is required for power only.
RAM size is dictated more by an operating system and application requirements. An
average desktop should not have problems running a 2263 application. Embedded CPUs
sometimes are limited by the peripherals performance. Please contact Sensoray for an
evaluation 2263 unit to test it with an embedded CPU of your choice.
