Abstract: Dans un système de transmission télévision selon le procédé "boîte aux lettres" on transmet à l'intérieur d'un format d'image 4:3 une image active ayant le format 16:9. Les inconvénients du procédé d'interligne (par ex. sautillement des lignes, scintillement des rebords) ne sont cependant pas résolus. On produit à l'émetteur un signal progressif 16:9 avec 575 lignes actives, on le transcode dans la direction verticale en 431 lignes, on le transforme en signal d'entrelacement de lignes, après quoi il est doté d'informations supplémentaires et transmis en format "boîte aux lettres" comme un signal de télévision compatible. Les informations supplémentaires se composent de parties de signaux avec lesquels on produit, à partir du signal d'entrelacement, un signal progressif avec une définition verticale qui est rapprochée de celle du signal source, et/ou à partir de composants verticaux du spectre qui sont séparés lors du transcodage à l'émetteur et/ou à partir de composants horizontaux plus élevés du spectre, qui sont séparés dans l'émetteur lors de la compression du format 16:9 en 4:3. Les informations supplémentaires correspondantes sont produites non pas pour la récupération d'un signal progressif avec 575 lignes actives mais pour la récupération du signal télévision progressif transcodé à 431 lignes. Un récepteur 16:9 fournit une image 16:9 remplissant le format dans une représentation progressive avec 431 lignes. La répartition des composants Y en trois plages de fréquences et l'association des composants Y de haute fréquence aux composants de couleur et l'utilisation d'une méthode des ''moyennes entre blocs'' (IFA) permettent d'éviter les perturbations de couleur croisée et de luminance croisée, et de transmettre en même temps les parties du spectre de luminance à haute fréquence.

Inventor: CLEASBY KENNETH GEORGE
IPC: H02P7/29
Filed: 1991-03-25
Abstract: The circuit provides digital control of current in an inductive load. A switching circuit 11 generates a square wave PWM voltage drive to the load 10, and the current is sensed by sensor 12. This current is fed back as signal V I , which is compared with two zone boundary signals V ON  and V OFF . The switching state is changed between ON and OFF accordingly. 
     The signals V ON  and V OFF  are generated by adding and subtracting (by adder/subtractor 20) a half-zone-width signal (stored as digital data) in zone width store 21 with the input signal D SIG . The zone position may be moved slightly up and down, under control of a counter 26 driven by the ON/OFF signal, to produce dither. The zone width may be selected in dependence on the input signal to reduce ripple at low signal, and to adjust the frequency. The switching circuitry may have multiple power supplies, and/or means for changing the connection of the load to the power supply to modify the rate of change of current and the direction of current in the load. 
     A separate analogue input (V IN ) may be summed with the feedback signal (V I ) or the D/A output (V C ) to modify the current magnitude or replace the input signal (D SIG ) as the main input signal.
