Title: Method for video signal bandwidth reduction
Inventor: THOMAS GRAHAM ALEXANDER
IPC: H04N7/26
Filed: 1992-05-15
Abstract: A temporally-subsampled video signal from a bandwidth reduction encoder is processed prior to transmission in order to reduce the judder effects that would otherwise be present when the encoded signal was viewed directly on a receiver not equipped with a bandwidth reduction decoder. A fraction 1/N of the samples are transmitted in the first field of each group of N fields, where N is the temporal subsampling ratio. Each of the other N-1 fields is formed by projecting the first field along the estimated motion trajectory to the appropriate time instant and adding to this projection the difference between another group of the N/1 samples and an estimate of these samples derived from those transmitted in the first field. At the decoder, the projected fields and the estimate of the samples can be derived from the samples in the first transmitted field of the group for each subsequent field. Using this information, the values of the other sets of samples can be derived from the subsequent transmitted fields, yielding the original temporally-subsampled signal. This signal is then decoded by the bandwidth reduction decoder.

Patent GB-2281163-A (GB)
Title: Optical transmitters
Inventor: DALEY ROBERT
IPC: H04B10/155
Filed: 1993-08-04
Abstract: An optical transmitter in a TPON (telecommunications over passive optical networks) network includes a servo circuit 41 for controlling the peak optical output power of pulses produced by laser 22. An optical sensor 23 is coupled optically to the laser 22 and provides a monitoring signal MONITOR indicative of the average optical power of the pulses. The servo circuit receives a digital demand signal DEMAND representing an intended peak power of the pulses, and produces from this and the data signal a modified demand signal MODDEM equal to the product of the duty cycle of the laser and the demand signal DEMAND. The servo circuit then adjusts the drive signals DRIVE applied to the laser 22 so as to maintain the monitoring signal MONITOR at or close to the modified demand signal MODDEM. Such a transmitter can provide effective peak power control, even when the average duty cycle of the modulating data signal is low, without requiring a fast sensor and fast associated circuitry. <IMAGE>
