Appeal No. 2004-2185

End-to-end feedback is used in the on demand case
to control the flow. In the multicast case, the

the control connection to the session agent on the
media server passing flow control feedback as well as

stream will be provided by the system.

lines 42-49, Tables 1-5 at columns 13 and 14 also indicate the

resolution desired among the base layers and first enhancement
layers.
It therefore appears to us from our study of this reference
that the nature of the arguments we noted earlier in the general
manner that appellant presents as to each of the claims on appeal
are not well-founded. We agree, on the other hand, with
appellant's view that Bolot does not teach anything related to
enhancement layers. Significantly, however, Bolot's discussion
at both columns at page 58 and, as noted by the examiner, the
substance of column 1 of page 59 emphasizes that scalable
feedback control systems exist for multicast video distribution
systems in a feedback manner. To the extent the artisan may
construe the teachings as Chaddha as not clearly indicating the
ability to feedback in any environment, including a multicast
