We find from this disclosure of Dureau that in the
alternate embodiment of figure 3, the video data is transferred
using the faster wide-band network through satellite 35, whereas
the narrow-band data such as text data is transferred over the
communication channel 59, which is a low bit-rate link. We note
that in the alternative embodiment of figure 3, Dureau states
that the wide-band Internet data is encoded by encoder and
multiplexer 25, whereas the narrow- band data is transferred
over communication channel 59. Dureau does not state that the
narrow-band Internet data is sent to encoder 25 before
transmission to the decoder. Thus, at first blush, it would
appear that Dureau encodes the wide-band video data but does not
encode and multiplex the narrow-band data. However, careful
review of Dureau reveals that there are in fact two decoders,
namely decoder 130, which works with renderer 140 to convert the
received Internet data to MPEG, and decoder 25 which decodes and
multiplexes the Internet data, converted to MPEG by decoder 130
and renderer 140, for transmission over the wide-band network.
We therefore find that since all of the Internet data is encoded
into MPEG by decoder 130 and renderer 140, that Dureau encodes
all of the Internet data, and does not encode the wide-band data
to MPEG, while leaving the narrow-band data such as text in the
