1. A method for revising a power state of a device in a mobile display digital interface (MDDI) communication system, the method comprising the steps of:
- receiving a display power state packet sent from a host to a client, the display power state packet comprising;
information specifying a device associated with the client, wherein the device information comprises a single-bit identifier as to whether the client is the main client or an alternate client, andinformation specifying a power state for the device, wherein the power state information comprises a field that allows for at least three different power state commands; and
implementing the device information and the power state information by the client, wherein implementing comprises placing the specified device in the specified power state.

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.
