Abstract

Interface board for an IBM compatible micro-computer, with a TV/Videocircuit using an electronic system. The connection board either plugsdirectly into the micro-computer, or remains outside on the RGB output. Thismicro-computer/video interface board has three outputs: one for the TV signal(PAL SECAM/NTSC), an Analog RGB signal with synchronisation and a Digital RGBsignal. An external synchronisation system (Genlock) synchronises themicro-computer images with those from the Video.

Description

   Carte de connexion micro-ordinateur -circuit de   TV/Video.   



  L'invention concerne l'interfaçage de tout micro-ordinateur IBM PC/XT/AT ou PS, y compris les compatibles, avec un circuit de TV/VIDEO au moyen d'un système électronique : La carte de connexion. Celle-ci, soit s'enfiche directement dans le micro-ordinateur, soit, se place extérieurement sur la sortie RGB. 



  Il est bien connu que l'écran du téléviseur et le VDU de l'ordinateur sont, en dépit des apparences, issus de technologies séparées par une génération. 



  Le micro-ordinateur envoie à son unité d'affichage des signaux numériques, lesquels sont convertis dans un adaptateur graphique ( suivant différentes normes : CGA, EGA, VGA...) qui permet alors la reproduction d'images sur son écran. 



  En vidéo, c'est un tout autre principe qui est appliqué: les signaux sont transmis sous formes d'ondes analogiques. Une incompatibilité complète règne entre ces deux mondes. 



  La carte de connexion contourne cette incompatibilité en transformant le signal RGB digital en un signal RGB analogique tout en traitant les images graphiques et textuelles pour les afficher sur l'écran TV/VIDEO. A cette fin, elle incorpore différents codeurs qui transforment le signal RGB analogique en un signal Vidéo composite standard Broad Cast dans les différents Standards ( PAL/SECAM/NTSC ). 



  La carte permet également la synchronisation interne ou externe soit sur l'horloge interne de la carte soit sur un signal externe Vidéo composite ou Black Burst ou même Fast Blanking. 



  Cette carte d'interfaçage micro-ordinateur vidéo a trois sorties : un signal TV (PAL SECAM/NTSC ), un signal RGB Analogue avec synchro et un signal RGB Digital. Un dispositif de 

 <Desc/Clms Page number 2> 

 synchronisation externe ( Genlock ) synchronise les images du micro-ordinateur avec celles de la Vidéo ( camera, magnétoscope et autres... ). 



  Elle admet également un super imposeur. 



  Il devient ainsi loisible à l'utilisateur de présenter les images générées par son micro-ordinateur sur écran(s) de TV, voire sur écran géant qui sera du type Vidéo et non Data. 



  Ces données peuvent également être enregistrées sur vidéo-cassettes. 



  L'accès à la vaste bibliothèque d'applications sous MS-DOS ( tableurs, traitements de textes, animatiques, et autres bases de données ) demeure acquis. 



  Le système enregistre tout programme informatique sur vidéo-cassette pour le présenter d'une manière active lors de formation. 



  En mode genlock, le système permet le mixage de signaux informatiques ( textes, graphiques ) et de signaux vidéo ( film vidéo ). Il autorise l'incrustation de films vidéos ou le mélange de textes et de dessins en surimpression sur des images de caméras ou de magnétoscope, en utilisant le superimposeur à défaut d'un mixer d'images.

   Microcomputer connection card - TV / Video circuit.



  The invention relates to the interfacing of any IBM PC / XT / AT or PS microcomputer, including compatible ones, with a TV / VIDEO circuit by means of an electronic system: The connection card. This, either plugs directly into the microcomputer, or is placed externally on the RGB output.



  It is well known that the television screen and the VDU of the computer are, despite appearances, from technologies separated by a generation.



  The microcomputer sends digital signals to its display unit, which are converted into a graphics adapter (according to different standards: CGA, EGA, VGA ...) which then allows the reproduction of images on its screen.



  In video, a completely different principle is applied: the signals are transmitted in the form of analog waves. There is complete incompatibility between these two worlds.



  The connection card gets around this incompatibility by transforming the digital RGB signal into an analog RGB signal while processing the graphic and textual images to display them on the TV / VIDEO screen. To this end, it incorporates different encoders which transform the analog RGB signal into a Broad Cast standard composite video signal in the different Standards (PAL / SECAM / NTSC).



  The card also allows internal or external synchronization either on the internal clock of the card or on an external signal Composite video or Black Burst or even Fast Blanking.



  This video microcomputer interface card has three outputs: a TV signal (PAL SECAM / NTSC), an analog RGB signal with sync and an RGB Digital signal. A device for

 <Desc / Clms Page number 2>

 external synchronization (Genlock) synchronizes the images of the microcomputer with those of the Video (camera, video recorder and others ...).



  She also admits a super taxman.



  It thus becomes possible for the user to present the images generated by his microcomputer on TV screen (s), or even on a giant screen which will be of the Video type and not Data.



  This data can also be recorded on videotapes.



  Access to the vast library of applications under MS-DOS (spreadsheets, word processors, animatics, and other databases) remains acquired.



  The system records any computer program on videocassette to present it actively during training.



  In genlock mode, the system allows the mixing of computer signals (texts, graphics) and video signals (video film). It authorizes the inlaying of video films or the mixing of texts and drawings superimposed on images of cameras or a video recorder, using the superimposer if there is no image mixer.
