Methods and apparatus for low power audio visual interface calibration

A method for calibrating operation of at least a transmitter for a receiver, based on one or more minimum receiver requirements of the receiver, comprising:

• during a calibration mode:
• configuring one or more receive path components;
• determining the one or more minimum receiver requirements of the receiver, the one or more minimum receiver requirements being based at least on a bit error rate (BER) calculated from a received test pattern;
• calibrating one or more transmitter settings based at least in part on the one or more minimum receiver requirements, the one or more minimum receiver requirements comprising at least a minimum eye requirement specific to the receiver;
• assigning the calibrated one or more transmitter settings to one or more relative anchor points;
• storing the one or more relative anchor points;
• and
• during a subsequent operation mode:
• initializing a link based at least on the stored one or more relative anchor points.

A non-transitory computer readable apparatus comprising media configured to contain at least one computer program having a plurality of instructions, said plurality of instructions which, when executed:

• determine one or more minimum first receiver requirements of the receiver;
• calibrate one or more first transmitter settings based at least in part on the one or more minimum first receiver requirements;
• assign the calibrated one or more first transmitter settings to one or more relative anchor points;
• store the one or more relative anchor points;
• and
• responsive to a subsequent operation, initiate a link based on the stored one or more relative anchor points.
