<P>PROBLEM TO BE SOLVED: To provide a data digital interface for transferring digital data between a host device and a client device at high speed. <P>SOLUTION: A data interface is for transferring the digital data between a host 202 and a client 204 over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control data and digital presentation data. A signal protocol is used by link controllers which are configured to generate, transmit, and receive a packet forming the communication protocol and to form the digital data into one or more types of data packets. At least one link controller resides always at the host device. The link controllers are coupled to the client 204 through the communication path, The interface provides a cost-effective, low power, bi-directional, and high-speed data transfer mechanism over a short-range "serial" type data link. <P>COPYRIGHT: (C)2010,JPO&INPIT |
