Each video channel captures at the full frame rate (30 fps for NTSC or 25 fps for PAL), which results in an aggregate frame rate of 120 fps for NTSC or 100 fps for PAL. The Model 953-ET compresses the A/V streams into MJPEG, MPEG-4, H.264, or MPEG-TS format for video, and with G.711 or AAC format for audio.
The encoding engine supports ultra-low latency, full frame rate encoding of two video streams from its single composite video input and sends the streams out over the PCI-Express x1 link. The video streams can be displayed on a monitor, saved on a storage device such as HD/SSD, or streamed over an IP network. The Model 953-ET can also perform as a 4-channel decoder, converting a compressed A/V stream into standard analog video and audio signals. Seven transparency levels of overlay images can be displayed on top of the composite video output, as well as up to 160 characters of text overlay for each channel prior to compression.
This extended temperature, small form factor board is ideal for applications where processor performance is critical. The Model 953-ET is well-suited for capture of multiple video sources, such as local/remote video surveillance & traffic monitoring, digital video recording/streaming, and other video processing applications. Sensoray provides SDKs for the Model 953-ET that include drivers, programming examples and comprehensive documentation, for both Windows and Linux operating systems.
