decoded. In order to reduce bit rate, a desired result in information transmission, the
invention compresses data by representing segments of the information by symbols
corresponding to generic objects that may be recognized from content in the aural or
video information. To the extent that portions of the content can be identified as
corresponding to generic objects housed in libraries containing generic object sets in
the encoder and decoder, only the symbol for the generic content, and the
unrecognized material need be encoded for transmission and decoded after
transmission and thereby substantially reduce the amount of information that must
actually be conveyed in the digital data stream.
Representative independent claim 1 is reproduced as follows:
1 . A system for transferring a data signal including a transmitter having
an encoder and a receiver having a decoder, comprising:
said encoder including a object selector for identifying a signal segment
from the group of speech, audio, video and graphic signals, each selected
segment comprising a representation of an information quantity;
wherein said encoder includes a plurality of encoder libraries, one
of said libraries containing a generic feature representation of an
information quantity and a symbolic code corresponding to said generic
feature representation of said information quantity; and
said decoder having a second plurality of libraries corresponding to
said plurality of encoder libraries, and one of said decoder libraries
containing said generic feature representation of said information quantity
and said symbolic code corresponding to said generic feature information
quantity.
