Richard John Barry has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8584255
    Abstract: A networked Conditional Access Module provided on an IEEE 1394 network, by defining a Conditional Access Module as a Conditional Access Subunit of the IEEE 1394 network. There is provided an AV/C Conditional Access Commands to allow communication between the Conditional Access Subunit and other Subunits on the network. The Conditional Access Subunit is configured to receive AV/C Conditional Access Commands over the IEEE 1394 network from another subunit, and means to is also configured to transmit AV/C responses over the IEEE 1394 network in response to the received AV/C Conditional Access Commands.
    Type: Grant

  • Patent number: 6591419
    Abstract: A method of transmitting a transport stream over an IEEE 1394 Serial Bus comprising stripping out of the transport stream identifiable unrequired data so as to reduce the bandwidth of the transport stream, a digital multi-media receiver for transmitting a transport stream to a Conditional Access Module on an IEEE 1394 Serial Bus including a reader for reading the contents of the transport stream and identifying data which is not required for processing by a Conditional Access Module, a stripper for stripping out at least some of the identified unrequired data from the transport stream and a transmitter for transmitting all of the remaining data of the transport stream which has not been stripped and a network of digital multi-media devices connected by means of an IEEE 1394 Serial Bus whereby a first device sends such a stripped transport stream to a second device over the IEEE 1394 Serial Bus.
