Title: Adaptive program guide device interruption detection
Inventor: ZHOU YIMING
IPC: H04N5/445
Filed: 1998-10-23
Abstract: The apparatus includes a device for receiving broadcast material and a detector for detecting whether a viewer has watched a programmer for a predetermined length of time(e.g. half of a program). If the user has watched a programme for at least the required time details of the program are stored in a user action log. This log is used over a period of time to develop a profile of viewer preferences and habits. This profile is used to produce a virtual channel having a schedule of programmes matching user preferences and also an adaptive programme guide that shows all the available programmes matching a user profile. If the viewer is not present the apparatus will record the programme from the adaptive guide that has the highest match with the user profile or if the user is distracted or interrupted the apparatus will record the program for playback from the point of interruption.

Title: Video line number converting apparatus
Inventor: KIM SEO-KYU
IPC: H04N7/01
Filed: 1998-12-24
Abstract: Apparatus for converting the number of video lines in an image includes a line memory 21 for delaying an input signal, an interpolator comprising two coefficient generators 22, 25, two multipliers 23, 24 and an adder 26 for weighting and adding the delayed and undelayed signals by respective coefficients dependent on the line number.

Patent GB-2338095-A (GB)
Title: Coprocessor opcode division by data type
Inventor: JAGGAR DAVID VIVIAN
IPC: G06F9/318
Filed: 1999-03-08
Abstract: A data processing system having a main processor and a coprocessor. The main processor responds to coprocessor instructions within its instruction stream by issuing the coprocessor instructions upon a coprocessor bus and detecting if the coprocessor accepts them by returning an accept signal. The coprocessor instructions include a coprocessor number and the coprocessor checks this number to see if it matches its own number(s) to determine whether or not it should accept the coprocessor instruction. A data type field within the coprocessor number in the coprocessor instruction also serves to specify one of multiple data types to be used in the coprocessor operation; particular coprocessors can interpret this part of the coprocessor number to determine data type. If the coprocessor supports multiple data types, then it has multiple coprocessor numbers for which it will issue accept signals and then uses the data type field to control the data type used. If a coprocessor does not support a particular data type then it will not issue an accept signal for coprocessor instructions that specify that data type. The main processor can then use emulation code to provide support for that coprocessor instruction.
