Abstract: Cyclic redundancy checks to improve link initialization processing and to exchange system error information are described. A cyclic redundancy check (CRC) checker including a unique pattern detector (710), a CRC generator (720), a CRC initializer (730) and a CRC verifier (740) is described. The CRC checker prepopulates the CRC generator for a unique pattern. Upon receipt (850) of the unique pattern within a data stream received over a digital transmission link such as an MDDI link, the CRC checker checks CRCs (860) without queueing and storing data. The CRC generator system can also intentionally corrupt CRC values to transmit system error information, the CRC generator system including a CRC generator (910), a CRC corrupter (920), and error detector (930) and an error value generator (940).

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 determining a maximum operating post skew calibration data rate in a mobile display digital interface (MDDI) communication system, the method comprising the steps of sending a skew calibration packet from a host to a client; performing a skew calibration adjustment by the client; sending a client capability packet from the client to the host, the client capability packet comprising the maximum post skew calibration operating data rate; and selecting an operating data rate by the host, the operating data rate comprising a data rate equal to or less than the maximum post skew calibration operating data rate 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.

Abstract: Una interfaz de datos para transferir datos digitales entre un ordenador y un cliente sobre una trayectoria de comunicacion que utiliza estructuras de paquete enlazadas para formar un protocolo de comunicacion para comunicar un conjunto preseleccionado de control digital y datos de presentacion. El protocolo de senal se utiliza por los controladores de enlace configurados para generar, transmitir y recibir paquetes que forman el protocolo de comunicacion, y para formar datos digitales en uno o mas tipos de paquetes de datos, con por lo menos uno residiendo en el dispositivo ordenador y siendo acoplado al cliente a traves de la trayectoria de comunicacion. La interfaz proporciona un mecanismo de transferencia de datos de costo efectivo, de baja potencia, bidireccional, de alta velocidad sobre un enlace de datos de tipo "serie" de corto alcance que se presta a si mismo para la implementacion con conectores en miniatura y cables flexibles delgados que son especialmente utiles para conectar elementos de visualizacion tales como micro-pantallas que se pueden llevar para computadoras portatiles y dispositivos de comunicacion inalambrica.
