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.

1. A method for communicating a client supported power state capability, and controlling client power, over a digital transmission link, the method comprising: providing a client capability packet comprising a client power state capability field, the client power state capability field having a value among a given plurality of different values, the client power state capability field representing the value as bit values at designated bit positions, wherein the first bit value indicates a first plurality of client supported power states, and the second bit value indicates a second plurality of client supported power states;sending the client capability packet from the client to the host after a request by the host;choosing, by the host, a specific client supported power state from the at least one client supported power state indicated by the value of the client capability field of the client capability packet; andsending a power state packet from the host to the client, the power state packet indicating the chosen specific client supported power state. 2. The method of claim 1 wherein at least one client supported power state comprises a low power state. 3. The method of claim 2 further comprising the step of not illuminating a display and not retaining a content of a frame buffer. 4. The method of claim 3 wherein the display comprises an alternate display. 5. The method of claim 2 further comprising the step of not illuminating a display and retaining a content of a frame buffer. 6. The method of claim 5 wherein the display comprises an alternate display. 7. The method of claim 1 wherein at least one client supported power state comprises a high power state. 8. The method of claim 7 further comprising the step of illuminating a display and refreshing the display from a frame buffer. 9. The method of claim 8 wherein the display comprises an alternate display. 10. The method of claim 1 wherein a first value of the client power state capability field indicates a first plurality of client supported power states, and a second value of the client power state capability field indicates a second plurality of client supported power states different than the first plurality. 11. The method of claim 1, wherein a given bit value at a first of the designated bit positions represents a first value of the client power state capability field, and a given bit value at a second of the designated bit positions represents a second value of the client power state capability field. 12. A system for communicating a client supported power state capability, and controlling client power, over in a digital transmission link, the system comprising: means for providing a client capability packet comprising a client power state capability field, the client power state capability field having a value among a given plurality of different values, the client power state capability field representing the value as bit values at designated bit positions, wherein the first bit value indicates a first plurality of client supported power states, and the second bit value indicates a second plurality of client supported power states;means for sending the client capability packet from the client to the host after a request by the host;means for choosing, by the host, a specific client supported power state from the at least one client supported power state indicated by the value of the client capability field of the client capability packet; andmeans for sending a power state packet from the host to the client, the power state packet indicating the chosen specific client supported power state. 13. The system of claim 12 wherein at least one client supported power state comprises a low power state. 14. The system of claim 13 further comprising a means for not illuminating a display and a means for not retaining a content of a frame buffer. 15. The system of claim 14 wherein the display comprises an alternate display. 16. The system of claim 13 further comprising a means for not illuminating a display and a means for retaining a content of a frame buffer. 17. The system of claim 16 wherein the display comprises an alternate display. 18. The system of claim 12 wherein at least one client supported power state comprises a high power state. 19. The system of claim 18 further comprising a means for illuminating a display and a means for refreshing the display from a frame buffer. 20. The system of claim 19 wherein the display comprises an alternate display. 21. The system of claim 12, wherein a first value of the client power state capability field indicates a first plurality of client supported power states, and a second value of the client power state capability field indicates a second plurality of client supported power states different than the first plurality. 22. The system of claim 12, wherein a given bit value at a first of the designated bit positions represents a first value of the client power state capability field, and a given bit value at a second of the designated bit positions represents a second value of the client power state capability field. 23. A non-transitory computer program product, comprising: non-transitory computer readable medium comprising:code for causing a communication of a client supported power state capability, and controlling client power, over a digital transmission link, the computer code comprising:code for causing a client capability packet be provided, the client capability packet comprising a client power state capability field, the client power state capability field having a value among a given plurality of different values, the client power state capability field representing the value as bit values at designated bit positions, wherein the first bit value indicates a first plurality of client supported power states, and the second bit value indicates a second plurality of client supported power states;code for causing the client capability packet to be sent from the client to the host after a request by the host;code for causing the specific client supported power state to be chosen, by the host, a specific client supported power state from the at least one client supported power state indicated by the value of the client capability field of the client capability packet; andcode for causing a power state packet to be sent from the host to the client, the power state packet indicating the chosen specific client supported power state. 24. The non-transitory computer program product of claim 23 wherein at least one client supported power state comprises a low power state. 25. The non-transitory computer program product of claim 24 further comprising code for causing a display not to be illuminated and code for causing a content of a frame buffer to not be retained. 26. The non-transitory computer program product of claim 25 wherein the display comprises an alternate display. 27. The non-transitory computer program product of claim 24 further comprising code for causing a display to not be illuminated and code for causing a content of a frame buffer to be retained. 28. The non-transitory computer program product of claim 27 wherein the display comprises an alternate display. 29. The non-transitory computer program product of claim 23 wherein at least one client supported power state comprises a high power state. 30.
