Patent EP-0450382-A2 (EP)
Inventor: FLAMMER GEORGE H
IPC: H04B1/7156
Filed: 1991-03-18
Abstract: A frequency-hopping packet communication system without a master clock or master control unit is based on use of a receiver's frequency hopping timing and identification to control communication. A frequency-hopping band plan, involving the number of channels and the pseudo-random pattern of frequency change and nominal timing of changes, is universally known to each node in the network. Frequency-hopping is implemented by the division of communication slots and the accumulation of slots into epochs, wherein each epoch equals the total number of available slots (number of channels times the number of time frames per channel). A transmitting node tracks the preestablished frequency-hopping pattern for its target receiver based on previously-acquired information. The transmission node identifies a receiver node and a current frequency channel of such receiver node. The transmission node then checks the frequency channel to determine if available (e.g., not in use and within an acceptable noise margin). If unavailable, the transmission node delays transmission to the identified node to a later slot. During the delay, the transmission node identifies another receiver node and a corresponding current frequency channel. The steps of identifying a receiver node and checking the corresponding current frequency channel are repeated until a node having an available frequency channel is identified. The transmission node then sends a packet to the selected receiver node at a frequency and for a duration defined according to the current slot. Such transmission node tracks the changing frequency of the selected receiver node to maintain frequency synchronization.

Abstract: A pseudo-random pattern generator (40) has modifiable feedback so that a variety of pseudo-random video patterns can be generated and used either directly, or after further manipulation, to control the mixing (52′) of two video sources. Control of a multiplexer (12) allows a variety of pattern lengths to be selected by altering which stages of a shift register (10) are supplied to a feedback exclusive-OR gate (14). Patterns with controllable granularity can be achieved by stretching each part of the noise pattern a selectable number of times along either or both axes. Horizontal stretching is achieved by clocking (28) the shift register (10) more slowly than the rate at which it is being read out. Vertical stretching is achieved by repeating the same pattern (18) on each of a selectable number (30) of consecutive lines. Varying the ratio of the stretching along the horizontal axis to the stretching along the vertical axis allows the aspect ratio of the grains of the pattern to be controlled. The values that are used to initialize (18) the shift register (10) can also be altered to achieve additional variation in the patterns generated. Two (or more) modifiable pseudo-random pattern generators (40,40′) can be used in combination with an array of selectable filters (48) to provide a controllable noise pattern generator (50) with coarse and fine pattern controls and selectable filtering of the output patterns produced.
