Title: Video compression method involving conditional replenishment
Inventor: MALTBY JOHN
IPC: H04N7/32
Filed: 1995-03-21
Abstract: The compression method performs a comparison between a first and second image to determine the location of differences therebetween and store theses locations in a list 220. Successive images are compared only at the locations within or neighbouring the localised areas and if no such differences exists for the location currently under consideration, the list 220 is updated to remove that location. A significant reduction in the number of pixels to be compared can be realised by focusing processing efforts on such localised areas thereby resulting in an increase in processing speed.

Patent GB-2321717-A (GB)
Title: Cholesteric optical filters
Inventor: ANDERSON DUNCAN JAMES
IPC: G02B5/30
Filed: 1997-01-31
Abstract: A cholesteric optical device such as a filter is formed from a polymerisable material by irradiating with UV light, changing a physical condition of the material and irradiating for a second time with a narrower band UV. The physical condition may be changed by adjusting the temperature or by the use of an electric or magnetic field. The process may be repeated for different wavelengths of UV so as to penetrate to different depths from the surface 2 to form infrared reflecting layer 17, and red and green reflecting layers 18, 19. For normally incident light the layers 18, 19 reflect red and green and transmit blue. For off axis illumination red light is reflected by the layer 17 and green light is reflected by the layer 18. The birefringence of the layers 17, 18 reverses the direction of circular polarisation of the blue light which thus passes through the green layer 19.

Patent GB-2319689-A (GB)
Title: An entropy encoder using context modelling with data reordering
Inventor: ZANDI AHMAD
IPC: H04N7/26
Filed: 1995-02-21
Abstract: The encoder comprises a bit reordering means that reorders the input data prior to passing it to the context modelling section. The reordering means is designed to reorder the input bits so that a context of a given bit is independent of other bits being processed in other sections of the encoder when said given bit is being processed in a context encoding section. The context modelling section outputs the input data together with a context of the data input and passes these pairs to a context sensitive encoder. This encoder, which may either be a pipeline or a parallel encoder, includes multiple stages at least one of which generates codewords based on the probability estimates of input bits given their paired context; the codewords are compressed versions of the input bits. This arrangement increases the speed of processing by ensuring that all the bits required to code a given codeword are available at the time the codeword is to be generated.
