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. |
