Abstract
Abstract A service provider node has an active network daemon running on it. Users control an adaptive pipeline via the active network capability of the service provider node by sending coded instructions to the service provider node. An adaptive pipeline is constructed within the service provider node according to control parameters contained in the coded instructions sent to it by a user. The adaptive pipeline includes a decode and an encode stage with zero or more intermediate filtering stages. The number and type of intermediate stages is determined by the values of the specified flow parameters. <IMAGE>

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A method for network transcoding of multimedia data flow
comprising the steps of: receiving from a network client by an active network daemon a
request for service containing flow parameters; decoding multimedia data flow requested by the request for service
in a way determined by the flow parameters in the request for service; encoding the decoded multimedia data flow in a way determined by
the flow parameters in the request for service ,thereby producing
transcoded multimedia data flow; and transmitting the transcoded multimedia data flow to the network
client.
Claim 2
Dependent Claim
52 words
A method for network transcoding of multimedia data flow according
to claim 1 further comprising, after the decoding step, the step of filtering
the decoded multimedia data flow in a way determined by the flow
parameters in the request for service, the filtered decoded multimedia
dataflow being input to the encoding step.
Claim 3
Dependent Claim
50 words
A method for network transcoding of multimedia data flow according
to claim 1 or 2 wherein the flow parameters indicate at least one of the
following: command type, ports, media type, bit-rate, frame rate, resolution,
end-to-end latency, interlace, signature, loss percentage, content
identification, code type, filter, filter parameter, prediction, hostname.
Claim 4
Independent Claim
94 words
An apparatus for network transcoding of multimedia data flow
comprising: means for receiving from a network client by an active network
daemon a request for service containing flow parameters; means for decoding multimedia data flow requested by the request
for service in a way determined by the flow parameters in the request for
service; means for encoding the decoded multimedia data flow in a way
determined by the flow parameters in the request for service, thereby
producing transcoded multimedia data flow; and means for transmitting the transcoded multimedia data flow to the
network client.
Claim 5
Dependent Claim
47 words
An apparatus for network transcoding of multimedia data flow
according to claim 4 further comprising means for filtering the decoded
multimedia data flow in a way determined by the flow parameters in the
request for service, if any filtering is desired as indicated by the flow
parameters.
Claim 6
Dependent Claim
50 words
An apparatus for network transcoding of multimedia data flow
according to claim 4 or 5 wherein the flow parameters indicate at least one
of the following: command type, ports, media type, bit-rate, frame rate,
resolution, end-to-end latency, interlace, signature, loss percentage, content
identification, code type, filter, filter parameter, prediction, hostname.
Claim 7
Independent Claim
53 words
An apparatus for network transcoding of multimedia data flow
comprising: a service provider node having an active network daemon capable of
receiving a request for service containing flow parameters from network
clients; an adaptive pipeline to transcode multimedia data flow in a way
determined by the flow parameters in the request for service.
Claim 8
Dependent Claim
132 words
An apparatus for network transcoding of multimedia data flow
according to claim 7 wherein the adaptive pipeline comprises: a decoder within the service provider node adapted to decode
multimedia data flow requested by the request for service in a way
determined by the flow parameters in the request for service; a filter coupled to the decoder, adapted to filter multimedia data flow
in a way determined by the flow parameters in the request for service, if any
filtering is desired as indicated by the flow parameters. an encoder coupled to the filter, adapted to encode the decoded
multimedia data flow in a way determined by the flow parameters in the
request for service thereby producing transcoded multimedia data flow; and means for transmitting the transcoded multimedia data flow to the
network client.
Claim 9
Dependent Claim
50 words
An apparatus for network transcoding of multimedia data flow
according to claim 7 or 8 wherein the flow parameters indicate at least one
of the following: command type, ports, media type, bit-rate, frame rate,
resolution, end-to-end latency, interlace, signature, loss percentage, content
identification, code type, filter, filter parameter, prediction, hostname.
