Understanding StudioZ SDI Functionality
With StudioZ SDI, you have the capability for real-time audio/video capture and playback. StudioZ SDI provides these basic capabilities:

Capture of video and audio to hard disk.
Playback of compressed and uncompressed video and audio from hard disk.
Hardware image compression and decompression to and from host memory.
JPEG compression/decompression.
Video input/output.

Uncompressed Capture and Playback
StudioZ SDI can capture and play back uncompressed video at full size and full rate. In this mode, the compression setting or Video Quality level is ignored. During video capture, the compression circuitry is bypassed and the uncompressed video is transferred to system memory, and then to the disk drive. During playback the process is reversed, again bypassing the decompression circuitry.

You can vary the size, brightness, contrast, hue, and saturation of the video as it is captured or played back in either compressed or uncompressed mode. You also can build video sequences from bitmaps generated by other applications.

JPEG Compression/Decompression
StudioZ SDI can capture and play back full-rate, full-frame video while performing hardware- accelerated motion JPEG compression and decompression. As video frames are digitized, they may be JPEG compressed, written to system memory, and then written to hard disk. This compression reduces the disk data rate required for full-rate, full-frame capture. The actual disk data rate is a function of the Video Quality value set during StudioZ SDI driver configuration, the image content of the video captured, and the amount of hard disk space that is used.

Motion JPEG encoding is an intraframe compression scheme. Each field is compressed individually, allowing frame boundary editing at any point in the video. The reconstructed JPEG image is not a bit-for-bit copy of the original image. You can adjust the image quality by changing the Video Quality value during StudioZ SDI driver configuration.

You can compress images (raster data blocks) in system memory and then store them in system memory. You can also decompress compressed images, with system memory serving as both the source and destination. With the exception of 720 x 486, images must be composed of an integer multiple of 16 x 16 pixel blocks.

StudioZ SDI provides direct memory access (DMA) capability to allow compression and decompression to occur with minimal host processor intervention.

Video I/O
StudioZ SDI accepts SDI input in either 525 line/59.94 Hz (NTSC) or 625 line/50 Hz (PAL) format. The 10-bit-per-component input is processed by input lookup tables for 10-bit-per- component to 8-bit-per-component transformation, and for brightness, contrast, hue, and saturation adjustment.

The StudioZ video encoder takes digital YUV 4:2:2 data and produces SDI, S-video, and composite outputs in either 525/59.94 Hz or 625/50 Hz formats. Lookup tables convert 8-bit- per-component output data to 10-bit-per-component output data and can provide brightness, contrast, hue, and saturation adjustment.
