Abstract: A cycle redundancy check, CRC, generator system (454) within a host system as well as a corresponding method is described. The system/method provides a mechanism to intentionally corrupt a CRC value. Thereby, the system (454) comprises a CRC generator (910) that generates a CRC value based on data to be included in a data packet to be transmitted over a digital transmission link, a CRC corrupter (920) that corrupts a CRC value generated by the CRC generator to convey host or related system status information, an error detector (930) that detects an error condition within a host system and provides instructions for the CRC corrupter to intentionally corrupt a CRC value. Also a corresponding CRC checker and method are described that can interpret intentionally corrupted CRC values.

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 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.

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.
