Video images in, e.g., a multimedia stream are scanned prior to
compression for transmission to recognize symbols, such as graphics
symbols and alpha-numeric characters. The types, positions, sizes, etc.
of the symbols are recorded to render symbol information, and then the
images are compressed with or without compressing the symbols, which may
be removed from the images prior to compression if desired. The
compressed video and symbol information are sent to a receiver, which
decompresses the video, optionally transforms the symbols, and then
inserts the symbols where indicated by the symbol information.
