Abstract: A multimedia sink device comprises: 1) a connector configured to be connected to an adaptor cable; 2) detection circuitry configured to detect when the adaptor cable is connected to the connector; and 3) hot plug detection (HPD) circuitry configured to determine if a configuration circuit is coupled to an HPD line of the multimedia sink device. In response to a determination that the configuration circuit is coupled to the HPD line, the HPD circuitry determines if the configuration circuit is associated with the adaptor cable. The HPD circuitry reads configuration data from the configuration circuit associated with the adaptor cable. The configuration data indicates the configuration circuit is resident in the cable adaptor and causes the multimedia sink device to increase a voltage level of a power supply voltage provided by the multimedia sink device to a multimedia source device via the adaptor cable.

Abstract: A passive cable adaptor for connecting a data source device with a display device is described. The adaptor has a packet-based interface connector at one end, the connector having a positive main link pin, a negative main link pin, a positive auxiliary channel pin, and a negative auxiliary channel pin. At the other end is a micro serial interface connector, wherein multimedia content is transmitted over the cable adaptor and electrical power is supplied over the cable adaptor simultaneously. The cable adaptor has an auxiliary and hot plug detect (HPD) controller utilized to map the auxiliary channel and HPD signals of the packet-based digital display to the micro serial interface ID signal.

Abstract: A passive cable adaptor for connecting a data source device with a display device is described. The adaptor has a packet-based interface connector at one end, the connector having a positive main link pin, a negative main link pin, a positive auxiliary channel pin, and a negative auxiliary channel pin. Also at the same end is a serial interface connector, such as a serial interface connector. At the other end is an upgraded serial interface connector (e.g., enhanced serial interface) connector having high-speed transmission pins, high-speed receiving pins, and a ground pin, wherein multimedia content is transmitted over the cable adaptor and electrical power is supplied over the cable adaptor simultaneously.

Abstract: A receiver is enabled to perform self-configuration of the main data link to receive and display video data. A video data signal is received through a data link having multiple channels or lanes at a specific bit rate. No link configuration data normally associated with the video signal is received. It is then determined which one or more of the channels of the data link are active in transmitting the data signal. A symbol pattern in the data signal is then identified. The symbol rate of the data signal is then synchronized with the local clock frequency. The local clock frequency is set to correspond to the actual bit rate of the data signal, thereby creating a signal-based clock frequency. This local clock frequency is set using only the data signal since no link configuration data associated with the signal is received. In this manner, the receiver configures or trains the link itself using only the video data signal and therefore, the receiver may be described as self-sufficient.
