摘要: Circuits, methods, and apparatus that allow a DisplayPort compatible host device to control data transactions over an I2C bus when communicating with a legacy monitor. One example includes an adapter having a compatibility register that may have a number of locations, where at least some of the locations correspond to I2C bus speeds. Values stored at these locations can indicate whether the adapter is compatible or incompatible with the corresponding I2C bus speed. Another example includes an adapter having a speed register that may have a number of locations, where at least some of the locations correspond to I2C bus speeds. A defined value written to one of these locations dictates the corresponding I2C bus speed.

摘要: Circuits, methods, and apparatus for registers to store information that may be used by devices in a display system. One example provides control and data registers in a display to store information pertaining to a display system that includes the display. The registers can store attributes of the display, a host device, and a branch device. The information may include an organizationally unique identifier, chip identification, major and minor chip revision information, and firmware major and minor revision information.

摘要: Circuits, methods, and apparatus that allow a host to determine the capabilities of a new display that has replaced a previous display in a display system. In one example, a host determines capabilities of a new display after the host exits a sleep state. After exiting the sleep state, the host wakes an adapter. The adapter determines the presence of a display and sends a hot-plug detect interrupt signal to the host. Following this, the host reads information stored in the display and determines whether the adapter has been connected to a new display. If the adapter is connected to a new display, the host reads capabilities such as supported resolutions and refresh rates from the display and make adjustments to graphics output data as necessary.

摘要: Methods and apparatus for protecting data bus ports and their corresponding PHY devices from taking damage associated with excess voltage across one or more signal pairs during an intermittent connection are provided. Such connections cause the signal pins to carry external device current which raises the signal voltage above the power rails, exceeding the PHY device ratings and causing PHY degradation or destruction. In an exemplary embodiment, an RC circuit is used to detect the voltage level across a signal pair. If this voltage level exceeds a certain preset voltage level, power to the outgoing serial bus port is shut off and return power is abated. While the circuit is responding, the exemplary embodiment uses a 3.6V Zener diode to bleed excess voltage to ground. A current monitor/limiter is also used for limiting current if the voltage level detected exceeds a certain threshold.

摘要: A high-speed optical interface for connecting computers to external I/O devices allows a number of native I/O formats to be encapsulated into PCIe Vendor Defined Messages (“VDMs”) for transfer over a single physical medium, preferably optical, and is thus referred to as the converged I/O (“CIO”) interface. Standard PCIe bridges are modified to support peer-to-peer communications, allowing greater exploitation of the capabilities of PCIe.

摘要: The present invention provides a method that protects symbol types by characterizing symbols as one of two types—DATA or NON_DATA, generating a symbol characterization bit, placing the symbol characterization bit at both ends of the symbol, and transmitting the symbol with the symbol characterization bits at both ends. Thus, a single byte error may affect a type bit in two consecutive symbols, and will affect one or the other of the type bits in a single symbol, but cannot affect both type bits in a single symbol.

摘要: Methods and apparatus for resolving valid networking structures for impromptu or ad hoc networks of audio-visual (A/V) components. In one embodiment, the networks are checked for problematic or “confounding” structures such as loops and non-unique paths between endpoints. Apparatus and methods are also disclosed which provide for network arbitration, and topology resolution. While the network itself is generally unidirectional during functional operation, each component utilizes an auxiliary bi-directional channel to perform the functions of arbitration and topology resolution. Control over network responsibilities may also be transferred from a master node to other nodes in the system for low level topology resolution, and relinquished back to the master node for normal operation.
