Abstract: Reduced-bandwidth versions of display signals that are currently being provided as outputs by multiple computer systems are received and processed for output, at another computer system, of a representation of each of the display signals. The received reduced-bandwidth versions may include, for example, versions of display signals that are generated by applying any one or more of the following to each of the display signals: scaling, segmenting, and compression. At a transmit side, respective requests for different reduced-bandwidth versions of a display signal that is currently being provided as an output by a computer system are received from multiple other computer systems. The different reduced-bandwidth versions of the display signal are generated and transmitted to the requesting computer systems responsive to the requests.

Abstract: An output signal indicative of one or both of a display signal and an audio signal currently being provided as output by a computer system is routed to or otherwise provided to another computer system for analysis. A determination is made as to whether the output signal satisfies one or more conditions for performing one or more actions. The action, or each action in the case of multiple actions, is initiated responsive to a determination that the output signal satisfies the condition(s). Other monitoring and control embodiments are also disclosed, and may be implemented in so-called Keyboard, Video, and Mouse (KVM) systems or non-KVM systems.

Abstract: An apparatus and method for transferring data between a host system and a communication network via a communication module wherein the communication module presents a UART-like interface to the host system. The communication module is comprised of an emulated UART module, a digital signal processor (DSP), and a DSP memory. The emulated UART provides a compatible UART-like front end for interlacing directly with a host system and additionally performs direct memory access-like (DMA) functions enabling the direct transfer of transmit data between the host system and DSP memory that is directly accessible by the DSP for modulation and/or other processing such as data compression. The emulated UART module additionally provides performance features such as adjustable buffering quantity thresholds for triggering interrupts to either the host system or DSP, and pacing features that provide the host system with the appearance and performance of a serialized UART.
