Abstract: A data interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range "serial" type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.

Abstract: A double data rate serial encoder is provided. The serial encoder comprises a mux having a plurality of inputs, a plurality of latches coupled to the inputs of the mux, an enabler to enable the latches to update their data inputs, and a counter to select one of the plurality of inputs of the mux for output. In another aspect, the mux provides a glitch-less output during input transitions. The mux includes an output selection algorithm optimized based on a priori knowledge of an input selection sequence provided by the counter.

Abstract: A packet structure for a Mobile Display Digital Interface (MDDI) includes a flexible sub-frame length to efficiently transmit large packets. A windowless video stream packet avoids repetitive transmissions of video packets when some parameters are unchanged, saving bandwidth. An enhanced reverse encapsulation packet combines the feature of a separate round trip delay packet with a separate reverse encapsulation packet. A link freeze is used to halt a transmission of a data stream at any point in the transmission and resume the transmission by a host.

Abstract: A method for routing pixel data from a scaled video stream packet within a client in a mobile display digital interface (MDDI) communication system, the method comprising the steps of receiving a predefined pixel content by the client from a host; scaling the predefined pixel content to a specific size by the client; sending the scaled pixel content to at least one specific display buffer from a plurality of display buffers specified by a pixel data attribute field received by the client; and displaying the pixel content of the at least one specific display buffer as well as a corresponding system.
