Patent Images
1. A method for intelligently switching between line coding schemes based on context, comprising:
- receiving one or more symbols according to a first context, at a receiving apparatus, the first context characterized by a first line coding scheme;
detecting, by the receiving apparatus, when a context switch to a second context will occur based on one or more media parameters; and
when the context switch occurs, changing, by the receiving apparatus, to the second context.

Abstract
Methods and apparatus intelligently switching between line coding schemes based on context. In one exemplary embodiment, an High Definition Multimedia Interface (HDMI) system is configured to transmit control and video data according to an 8B/10B line coding protocol, and data island data according to TERC4 (TMDS (Transition Minimized Differential Signaling) Error Reduction Coding 4-bit). Various elements of the disclosed HDMI devices are configured to determine when a context switch occurs, and thereafter seamlessly transition between the appropriate line code protocol.

9. An apparatus configured to intelligently switch between line coding schemes based on context, comprising:
-
a first interface configured to receive one or more symbols according to at least one of;
(i) a first context, the first context characterized by a first line coding scheme, and (ii) a second context, the second context characterized by a second line coding scheme;a processor coupled to the first interface; and a non-transitory computer-readable medium comprising one or more instructions which when executed by the processor, cause the apparatus to; detect when the context switch will occur based on one or more media parameters and a current state of a state machine; and when a context switch occurs, change context. - View Dependent Claims (10, 11, 12, 13, 14)

15. An apparatus configured to intelligently switch between line coding schemes based on context, comprising:
-
a sink configured to receive one or more symbols according to at least one of;
(i) a first context, the first context characterized by a first line coding scheme, and (ii) a second context, the second context characterized by a second line coding scheme;a source configured to transmit the one or more symbols according to the first and second contexts; a display element; a processor; and a non-transitory computer-readable medium comprising one or more instructions which when executed by the processor, cause the apparatus to; determine when a context switch should occur based on one or more media parameters and a current state of a state machine; and when a context switch occurs, cause the source to change the context. - View Dependent Claims (16, 17, 18, 19)
