摘要： A serial data transmission system in which a transmitter encodes data in accordance with a TMDS-like encoding algorithm and transmits the TMDS-like encoded data over a serial link to a receiver. The encoded data are transmitted as a run length limited (“RLL”) code word sequence, including transition-minimized code words. In some embodiments, the RLL code word sequence includes only Min words, including both DC balancing Min words and DC unbalancing Min words. In other embodiments, the RLL code word sequence includes both transition-maximized code words and transition-minimized code words. Other aspects of the invention are circuitry and methods for TMDS-like encoding of data for transmission as an RLL code word sequence.

摘要： A method, apparatus and system for pre-authenticating ports is disclosed. In one embodiment, an active port facilitating communication of media content between a transmitting device and a receiving device is identified, while the active port are associated with a first High-Definition Content Protection (HDCP) engine. Then, inactive ports that are in idle mode serving as backup ports to the active port are identified, while the inactive ports are associated with a second HDCP engine. Pre-authentication of each of the inactive ports is performed so the pre-authenticated inactive ports can subsequently replace the active port if a port switch is performed.
