    摘要: A method, apparatus and system for providing pre-authentication and keep- authentication of content protected ports system employing a ratio of one decipher processing engine (e.g., HDCP engine) associated with multiple ports is disclosed is disclosed. In one embodiment, a receiving device is pre-authenticated by a transmitting device, wherein the receiving device to receive a data stream from the transmitting device via a first data path. Further, a first High-Definition Content Protection (HDCP) engine is associated with a first port in the first data path, the first HDCP engine coupled with a second HDCP engine. The second HDCP engine is associated with a plurality of ports in a second data path, each of the plurality of ports associated with a memory pipe having state information relating to each of the plurality of ports, the state information being used to pre-authenticate the receiving device.

    摘要: Discovery of electronic devices utilizing a control bus. An embodiment of a method includes connecting a receiving device to a cable, where the cable includes a control bus. If the receiving device is in a disconnect state and a signal from a transmitting device is detected on the control bus, the device is transferred to a state for a first type of transmitting device. If the receiving device is in either the disconnect state or the state for the first type of transmitting device and a predetermined voltage signal is received from the transmitting device, then the receiving device is transferred to a state for a second type of transmitting device.

    摘要: The system preferably includes a unique transmitter that sends both clock and data signals over the same transmission line. The receiver uses the same transmission line to send data signals back to the transmitter. The transmitter comprises a clock generator, a decoder and a line interface. The clock generator produces a clock signal that includes a variable position falling edge (T0, T1, T3, T4) for pulse with modulation by the data (00, 01, 10, 11). The falling edge position is decoded by the receiver to extract data from the clock signal. The receiver comprises a clock re-generator, a data decoder and a returm channel encoder. The clock re-generator monitors the transmission line, receives signals, filters them and generates a clock signal at the receiver from the signal on the transmission line. The return channel encoder generates signals and asserts them on the transmission line. The signal is asserted or superimposed over the clock & data signal provided by the transmitter.

    摘要: Embodiments of the invention are generally directed to detection of cable connections for electronic devices. An embodiment of an apparatus includes a port for the connection of a cable, the port being compatible with a first protocol and a second protocol, the port including a connector for the second protocol, the port including multiple pins including a first pin and a second pin. The apparatus further includes a pull-up resistor coupled between the first pin and a voltage source, a pull-down resistor coupled between the second pin and ground, and a voltage detection element coupled with the second pin. The apparatus is to determine that a cable compatible with the first protocol is connected to the port if the voltage detection element detects a voltage above a first threshold.

An embodiment of an apparatus includes a port for the connection of a cable, the port being compatible with a first protocol and a second protocol, the port including multiple pins including a first pin for a first line and a second pin for a second line. The apparatus further includes a processor to determine a type of source device connected to the cable, where determination of the type of source device includes the apparatus detecting a low signal on the first line and a high signal on the second line, and, upon detecting the low signal on first line and the high signal on the second line, the apparatus initiates a discovery sequence, the discovery sequence including transmitting a signal sequence on the second line and attempting to receive the signal sequence on the second line. If the signal sequence is successfully received on the second line, the apparatus determines that a source device compatible with the first protocol is connected to the cable.

    摘要: Embodiments of the invention are generally directed to determination of physical connectivity status of devices based on electrical measurement. An embodiment of a method includes discovering a connection of a first device with a second device, and performing an electrical measurement of the second device by the first device via the connection between the first device and the second device, where performing the electrical measurement includes sensing by the first device of an element of the second device. The method further includes, if the sensing by the first device fails to detect the element of the second device and a predetermined condition for the electrical measurement is enabled, then determining by the first device that the connection with the second device has been lost.
