Abstract: Apparatus for serializing 2 parallel outputs of an all points addressable memory into successive data groups, each data group corresponding to a respective value for a pixel in an image wherein the bit-length of the pixel value is selectable, the apparatus comprising: a gate circuit having (i) 2 parallel input junctions connected to the outputs of the memory and (ii) 2 output junctions, wherein the gate circuit selectively converts each set of 2 parallel inputs at said input junctions into 2 successive data groups, each group having a bit-length of 2 bits, wherein each group is transmitted to 2 of the 2 output junctions; and a communication element for conveying to the gate circuit a signal which controls the bit-length 2 of data groups, wherein n is an integer 1

Abstract: In a publish/subscribe data processing broker network having a plurality of broker data processing apparatuses each of which has an input for receiving published messages directly from a publisher application and/or receiving subscription data from a subscriber application, a first broker apparatus 111 has: a software unit for receiving subscription data from a subscriber application 301; a software unit for providing an acknowledgement to the subscriber application to acknowledge that the subscription data has been received; a software unit for propagating the subscription data to a group of other broker apparatuses; a software unit for determining whether the means for propagating has propagated the subscription data to the group of other broker apparatuses; and a software unit for receiving an indication from the subscriber application that the acknowledgement should not be sent to the subscriber application until the means for determining has determined that the means for propagating has propagated the subscription data to the group of other broker apparatuses.

Abstract: In a publish/subscribe data processing broker network having a plurality of broker data processing apparatuses each of which has an input for receiving published messages directly from a publisher application and/or receiving subscription data from a subscriber application, a first broker data processing apparatus 12 has:a unit for receiving a data message published on a first topic by a first publisher application 201 and a unit for forwarding the received published data message to a subscriber application 203 which has requested, by entering subscription data, to receive a message on the first topic; wherein the first broker data processing apparatus sends a declaration to at least one other of the broker data processing apparatuses declaring that the first broker data processing apparatus is the only broker data processing apparatus that is directly communicating with a publisher application that is publishing on the first topic.

Abstract: In a publish/subscribe system comprising a network of broker data processors each of which can receive a published message directly from a publisher application 201 and/or receive subscription data directly from a subscriber application 204, an indication is provided as to whether the published message and/or the subscription data is to be considered as local to a particular broker data processor. The indication may be included in the message or subscription data and used to determine whether or not the message/data should be forwarded to others of the broker data processors.
