Model 953-ET is a PCIe/104 form factor audio/video codec that simultaneously captures four channels of analog video and four channels of audio. Each video channel captures at up to full frame rate (30 fps for NTSC or 25 fps for PAL). Model 953 implements H.264, MJPEG, or MPEG-4 compression for video (with MPEG-TS supported), and G.711 or AAC for audio. A low-latency video preview stream is also provided for each channel.
Model 953 is capable of decoding compressed sreams in a full duplex mode (simultaneously with encoding). The decoded audio/video data is available on analog outputs.
The board's PCIe/104 connector supports both stack-up and stack-down, so that the board can be stacked anywhere in a PC/104 stack or an EPIC stack. The board's full conformance to the PCIe/104 and PCI/104-Express specification guarantees that it won't mechanically interfere with adjacent boards. All operating power is obtained from the PCIe/104 bus connector; no external power supply is needed.
The unit is capable of simultaneously producing two different video streams from its single composite video input and sending the streams out over the PCI-Express x1 link. One of the streams can be a low-latency stream (in umcompressed format and useful for real time previewing) and the other compressed, or both streams may be compressed. Image resolution, compression type and bit rate can all be independently configurable for each compressed stream.
Up to 1024 bytes of application-supplied data may be inserted in the H.264 or MPEG stream, at a specified frame interval or single shot.
Video and audio are available as elementary streams or may be multiplexed in MP4 container format.
Model 953-ET supports transport stream using AAC audio and H.264 or MPEG-4 video.
The Model 953-ET eliminates "lip sync" problems by implementing hardware-generated timestamps to keep audio synchronized to the video.
One general purpose digital input and one output is provided for each channel. Both input and output are optically isolated. The input is sampled every millisecond, when a state change is detected a notification is sent to the application program.
For each channel of video output, overlay images can be displayed on top of the composite video output. The overlayed video may be sourced from either the composite video input or a decoded compressed stream. Image formats supported are Windows bitmap (BMP) and Portable Network Graphics (PNG), with 24 or 32 bits per pixel. Overlays support 7 transparency levels.
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. Decoding is guaranteed only for the streams captured with the Sensoray Model 953-ET. The following formats are supported for decoding: MPEG-4 (.m4v), H.264 (.264 or .h264), MP4 (.mp4) and MJPEG (.mjpg or .mjpeg).
Ultra-low Latency Preview
The Model 953-ET supports an ultra-low latency preview mode for real-time applications. When capturing in native resolution (704x480 for NTSC or 704x576 for PAL) this mode reduces the overall latency by approximately one frame time to around 35 ms.
Software Development Kits (SDKs) are available for both Linux and Windows developers. The SDKs include drivers, programming examples and comprehensive documentation to enable the users and programmers to quickly develop custom application software for the Model 953-ET.
