Invention
The invention relates to a MPEG-like information
distribution system. The invention provides a low cost apparatus
for compressing, multiplexing and, in optional embodiments,
encrypting, transporting, decrypting, decompressing and
presenting high quality video information in a manner that
substantially preserves the fidelity of the video information.
See page 2 of Appellants’ specification. Figure 1 depicts a high
level block diagram of an audio-visual information delivery
system. Figure 2 depicts a high level block diagram of a video
compression unit and a video decompression unit and suitable for
use in the audio-visual information delivery system of Figure 1.
See page 4 of Appellants’ specification. The video compression
unit 21 depicted in Figure 2 comprises three standard MPEG
encoders 218R, 218G and 218B and a multiplexer 219. Similarly,
the video decompression unit 43 depicted in Figure 2 comprises a
demultiplexer 431, and three standard MPEG decoders 432R, 432G
and 432B. See page 14 of Appellants’ specification. The MPEG
standards and other MPEG-like standards and techniques compress
