Block diagram

Technical specifications:

• Video output: RGB (RS-170)
• Color resolution: 8 bit per R,G,B components
• Resolution: 512x512 or 768x576 (chess)
• Power consumption: about 20 Watt
• Compression ratio: 3 (lossless) to 20 (preview)
• Up to 5 minutes of movie off a 1 GB hard disk
• software compression speed (the time is provided for one frame):
  less than 8(486DX2-66)/3(Pentium-90) seconds for 512x512 resolution
  less than 13(486DX2-66)/5(Pentium-90) seconds for 768x576 resolution
• Video standard: PAL, Y/C or analog component (Y,R-Y,B-Y) - Optional (with coder)

The software (DDFilmer) makes the compression and facilitates an assembly of the video from fragments, which are stored as a sequence of TGA files, a FLI file or other. During the playback, the compressed video data is read from the hard disk(s) and through the memory into the PHOENIX board. The latter decompresses the data in real time and passes the videosignal onto an RGB-monitor and/or through the coder into a VCR and/or TV-monitor. High speed data transfer is provided by a fast computer bus, fast adapters, and use of the host computer RAM as the video data transfer buffer.

Hardware requirements:

• PC AT/486 with PCI, EISA or VESA local bus (VLB)
• 16 MB of RAM (or more)
• Fast SCSI-2 hard drives (upto 4 disks)
• Fast SCSI-2 controller card on the respective fast bus (PCI, EISA or VLB)
• Sound card - if sound is to be used

Software requirements:

• DOS & MS Windows 3.XX or Windows-95.
• ASPI-manager for SCSI-controller card - optional
• Hard drive defragmentation software - recommended
• Sound card driver for Windows - if sound is to be used
