High data rate interface with improved link synchronization
First Claim
1. A method executed in a processor comprising a controller circuit for ensuring that all data signals are simultaneously being driven during a transmission of a reverse link encapsulation packet in a mobile display digital interface (MDDI) communication system, the method comprising the steps of:
- disabling a host'"'"'s data line drivers prior to a last bit of a turn around 1 period of the reverse link encapsulation packet;
enabling the client'"'"'s line drivers at a beginning of the turn around 1 period of the reverse link encapsulation packet; and
simultaneously driving the data signals by the host and the client.

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.
