CA 2321633

A new scheme to transfer bidirectional data streams between a digital display and a computer is disclosed. This bidirectional data transfer can make several I/O devices attach to a display. Existing digital display interfaces are usually unidirectional from a computing to a display. Due to the nature of the existing clocking scheme, backward data transfer from the display side to the computer requires a backward clock. This invention discloses a scheme to send data bidirectionally without sending the additional backward clock. This invention also discloses a scheme to tolerate jitters from the clock source. With this approach, this new interface can make a digital display an I/O concentrator.

L'invention concerne un nouveau schéma de transfert permettant de transférer des flux de données bidirectionnels entre un afficheur numérique et un ordinateur. Ce transfert bidirectionnel permet de connecter plusieurs dispositifs E/S à un afficheur. Les interfaces d'affichage numériques existantes sont généralement unidirectionnelles, allant de l'ordinateur vers l'afficheur. De par la nature du schéma d'horloge existant, le transfert de données en retour, allant de l'afficheur vers l'ordinateur, exige une horloge de retour. L'invention concerne un schéma de transfert permettant d'envoyer des données dans les deux directions sans envoyer d'horloge de retour supplémentaire. Elle concerne également un schéma de transfert qui tolère la gigue de la source d'horloge. Avec cette approche, la nouvelle interface peut transformer un afficheur numérique en concentrateur E/S.
