- IMPACT Compression provides analog video input, output and real-time JPEG
- compression and decompression for the Indigo2 IMPACT line of desktop
- workstations.
-
- IMPACT Compression on the Indigo2 IMPACT platform works with the R4400
- CPU and the Solid IMPACT, High IMPACT, and Maximum IMPACT graphics board
- sets. It can also be used with the IMPACT Video option to provide digital
- I/O and other functionalty.

- With two independent JPEG codecs, Indigo2 IMPACT Compression may be used
- for video editing applications, or simply compressed data capture and
- playback.
-
- * 2 independent channels of JPEG compression and/or
- decompression
-
- * Memory to/from Video or Memory to Memory operations
-
- * Compression ratios as low as 2:1.
-
- AAAAnnnnaaaalllloooogggg VVVViiiiddddeeeeoooo
- Industrial quality video input and output enables video on the desktop.
-
- * 1 8-bit YUV 4:2:2 input
-
- * 1 8-bit YUV 4:2:2 output
-
- * Genlock input

- Applets demonstrating the abilities of the IMPACT Compression device are
- available if impactcomp.sw.examples is installed. The source code for
- the examples is installed in the
- /usr/people/4Dgifts/examples/dmedia/compression/impactcomp directory.
- The examples include:
-
- * blendicomp: Real-time decompression of a JPEG compressed
- movie file, alpha blended with graphics (Requires an
- IMPACT Video option).
-
- * compdecomp: Real-time compression of video input and
- decompression to video output to demonstrate the effect of
- a selected compression ratio on the video source images.

- The following are things to be aware of with the IMPACT Compression
- product:
-
- The impactcomp.sw.eoe and impactcomp_video.sw.eoe images must be
- installed. These images pre-require Digital Media 5.7.
-
- The impactdm.sw.common and patchSG0001141 images must be installed.
-
- Input timing and genlock cannot be changed while any video application is
- running.
-
- The default control values have no effect until a video path is created.
- They are used as suggestions for applications such as videoin to specify
- the desired input source.
-
- The video tools supplied in /usr/sbin are: videoin, videoout,
- videopanel, vidtomen, memtovid, vintovout, and vlinfo.
-
- SSSSYYYYNNNNCCCC MMMMOOOODDDDEEEESSSS
- There are two sync modes in which the products can run:
-
- 1. Internal - Used when performing graphics to video out or when the
- input video signal is poor quality. All timing is generated internally.
-
- 2. Genlock - Used when the output timing must be locked to an external
- timing source. IMPACT Compression can genlock to the reference input or
- the analog video input.

- The following VL packing formats are supported by IMPACT Compression for
- memory transfers. Note that the different memory nodes may support
- different formats and packings. See the IMPACT Compression Programmer's
- Guide for information on each node.
-
- For memory transfers, the following packings are natively supported (i.e.
- require no software conversion): VL_PACKING_YVYU_422_8,
- VL_PACKING_RGBA_8.
-
- Additionally, the following packings are supported for transfers through
- a software conversion: VL_PACKING_VUY_411_SV, VL_PACKING_RGB_332_P,
- VL_PACKING_RGB_8, VL_PACKING_Y_8_P, VL_PACKING_YVYU_422_8.
