Title: Multiple Envelope Tracking System for an Active Antenna Array
Inventor: KENINGTON PETER
IPC: H01Q3/26
Filed: 2010-12-17
Abstract: In an active antenna array comprising different transmission paths 106-108, power amplifiers 121-123 are powered by variable power supply units 164-166 each controlled according to a common envelope signal 172 which is detected, generated and tracked by an envelope detection system 161. A feedback signal 146-148 is then selected by a switch 151 and used to update the Digital Signal Processor 154 which controls predistorters 101-103. Power amplifiers are more efficient when at maximum power, and envelop tracking allows the amplifier voltage to be instantaneously matched to requirements for Long Term Evolution (LTE) standards without requiring a separate envelope tracker for each transmission path. The common envelope may be based on that of a single transmission path or a weighted average of several.

Title: Analysing audiences for channels delivered to a population of households
Inventor: ROBERTS ANDREW
IPC: H04H60/31
Filed: 2012-05-29
Abstract: The present invention includes a method of analyzing audiences for channels delivered to a population of households, each household having one or more presentation devices operable to present a channel for viewing by one or more members of the household, the channel being selected from a signal provided to the household by a service provider and fed to a presentation device via a signal source coupled to the presentation device. The population of households includes a first sample of households, the members of which households compile viewing information including data indicating which channels were viewed, who by, when, and the service provider of the signal from which the channel was selected and a second sample of households, each having a presentation device coupled to a channel selector device receiving a signal from one of a predetermined one or more service providers. The channel selector device is both a signal source configured to select a channel from the signal provided to the household by the service provider and feed it to the presentation device and a means to transmit channel selection data indicating which channels were selected and when via a return path data. An audience analysis unit obtains the viewing information from the first and second samples of households and allocates to each household from the second sample a household from the first sample from which is copied a portion of the viewing information from the first sample household for which the channel was selected from a signal provided by a service provider other than the predetermined one or more service providers e.g. a terrestrial aerial with no return path. This copied portion is then stored for use as data representing the viewing of channels in the household from the second sample. Embodiments of the present invention may be used to integrate STB and Peoplemeter (people meter) panels by fusing households to establish donor and recipient relations for sharing viewing records and hence to establish a large sample size for audience analysis.

Title: Error Concealment for an image display system
Inventor: FRETAY TRISTAN HALNA DU
IPC: H04N19/895
Filed: 2012-10-31
Abstract: A method and associated device for processing an image belonging to a set of images in a display system (such as a multi-projector display) in which the image comprises several image blocks. Image blocks comprising missing or erroneous data are detected, 302, and reconstructed, 303, using an error concealment method (such as a temporal concealment method.) For each image block in the image a distance value with respect to a corresponding image block of a previous image is also determined (Figure 7, 701.) Each determined distance value is then compared with a determined threshold value (Figure 7, 703) and image blocks replaced according to the result of the comparison. The threshold value may be representative of the impact caused in the image by the reconstruction of the image block comprising missing or erroneous data and may be calculated by determining a distance value for each image block bordering an image block comprising erroneous or missing data (Figure 5, 501) and then applying a function (such as averaging) on the set of determined distance values (Figure 5, 502.) The method may be used to recover missing or erroneous data while maintaining image coherency by reducing the number of visual artefacts generated.
