Patent ID: 8650304

Claim:
A method of determining a data rate for a communication link between a host and a client in a mobile display digital interface system, the method comprising: selecting, by the host, a first data rate at which to operate the communication link, the first data rate being within a minimum data rate range or a preselected minimum rate; requesting a client capability packet by the host from the client; receiving by the host the client capability packet comprising a pre-calibration data rate capability field having a first value specifying a maximum data rate at which the client can operate prior to performing forward link skew calibration and a post-calibration data rate capability field having a second value specifying a maximum data rate at which the client can operate after performing forward link skew calibration; selecting by the host a second data rate at which to operate the communication link, the second data rate being equal to or less than the first value of the pre-calibration data rate capability field; sending by the host a forward link skew calibration packet to the client if the client capability packet indicates that the client is capable of responding to a forward link skew calibration packet, the forward link skew calibration packet including a calibration data sequence allowing the client to perform a forward link skew calibration during a duration of the calibration data sequence; and selecting, by the host, after sending the forward link skew calibration packet, a third data rate at which to operate the communication link, the third data rate being less than or equal to the second value of the post-calibration data rate capability field.
