Abstract: An encoding data processing apparatus generates a video material item marked copy by embedding a payload data word into the video material item. The video material item includes plural video frames. A code word generator generates a water mark code word from the payload data word and reads data representing the water mark code word into a shuffle data store. A shuffle processor generates pseudo randomly at least one address within an address space of the shuffle data store for each video frame and reads data representing part or parts of the water mark code word out from the data store at locations identified by the pseudo randomly generated address. A data embedding processor receives the video material item and embeds the data representing the part or parts of the water mark code word read out from the shuffle data store for each frame into a corresponding frame of the video material item.

Abstract: A digital image processing apparatus for applying pixel-based color correction to an input image to generate an output image is described herein. The apparatus includes color correction logic arranged to provide two or more color correction processes. Each color correction process has a respective associated locus in a color space and a respective associated color mapping operation. The color correction processes are arranged as a succession of processes so that the results of a color correction process form the input to a next such process in the succession. Each color correction process is operable to detect whether each pixel lies within the respective locus in color space and, if so, to apply the color mapping operation to that pixel. Each color correction process after the first process in the succession is configured to inhibit color mapping in respect of the loci associated with previous processes in the succession.

Abstract: An intercooler assembly includes a housing that defines an internal space containing a plurality of tubes. A joint between a tube and a tube plate is created by a laser welding process. A form presses the walls of the tube outwardly to form the flange. The downward force of the form not only creates the desired flange, but also exerts a pressure that holds the flange against the tube plate. The form provides for the transmission of laser energy to that the creation of the flange can be performed concurrently with the welding process.

Abstract: A communications network in which service flows between an end user and the network are transported via a gateway (8) which identifies different service flows and notifies them to a credit control function (12) of the network. The credit control function grants a cache representing an amount of and end user's credit and/or an amount of network resource to the gateway for the identified service flows and provides instructions to the gateway for the identified service flows which enable the gateway to share units of the caches between service flows, for example if there is a threat of a service flow becoming blocked due to a lack of credit in an end user's account.

Abstract: An image processing apparatus is operable to embed data into an image. Images such as those generated from an inter-laced scan may comprise a frame of image data, the frame comprising first and second image fields. The image processing apparatus comprises a combining processor operable to introduce the data to be embedded into at least one of the first and second fields of the image frame. As such a likelihood of a perceivable effect of the embedded data on the image may be reduced, because the images are viewed as a frame. The embedded data may also have an increased likelihood of being detected because some processing may effect the image frame more then the fields of the image. The combining processor may be operable to represent the data to be embedded in a transform domain form, and, in combination with a transform processor, combine the data to be embedded with the first and/or second fields with the image in a transform domain form or a spatial domain form.

Abstract: An HQ tube arrangement suitable for packaging within a vehicle may be designed by creating a mathematical model representing a tube arrangement having a first passageway and a second passageway fluidly connected to the first passageway at first and second junctions. The second passageway is divided by the junctions into first, second, and third passages. Lengths are associated with each of the first passageway and the first, second, and third passages. A filter parameter, based upon an average transmission loss for a particular frequency over a standard deviation, is analyzed as a function of the lengths. Lengths are chosen based upon analysis of the filter parameter. Portions of the outer walls of the first and second passageways may be secured to or common to one another so that lengths of the passageways run along side of each other to provide a more compact HQ tube arrangement.
