Abstract

According to some embodiments of the invention, a method of minimizing buffer requirements, in a packet based multimedia system having a multimedia source device coupled to a multimedia display deviceby way of a bi-directional auxiliary channel arranged to transfer information between the display device and the source device and vice versa and a unidirectional main link arranged to carry multimedia data packets from the multimedia source device to the multimedia display device is disclosed. Interspersing special characters that allow the display device to distinguish each bit of pixel data included in the data packets thereby requiring only a small FIFO type buffer unit.

Description

technical field [0001] The present invention displays a device. More specifically, the present invention relates to digital display interfaces suitable for coupling a video source to a video display device. Background technique [0002] Currently, video display technology is divided into analog-type display devices (such as cathode ray tubes) and digital-type display devices (such as liquid crystal displays or LCDs, plasma displays, etc.), each of which must be driven by a specific input signal in order to successfully Display the image. For example, a typical analog system includes an analog source (such as a personal computer, DVD player, etc.) directly coupled via a communications link to a display device (sometimes called a display sink). The communication link usually takes the form of a cable well known to those skilled in the art, such as an analog VGA cable in the case of a PC, otherwise known as a VGA DB15 cable. For example, a VGA DB15 cable includes 15 pins, ea...
