摘要： In a communication system having a master-slave arrangement communicating with each other using the RS485 protocol, an FPGA with a buffer memory is provided in the master and slave, respectively, to handle the actual communication. The CPUs of the master and slave transfer data to and from the respective buffer memory. The master's FPGA initiates and maintains communication with the slave's FPGA. The masters FPGA and the slave's FPGA communicate with each other using the RS485 protocol by transmitting requests, acknowledgements and data. From the standpoint of the CPUs of the master and slave, the communication appears to be full duplex, although the actual communication between the FPGAs is half duplex. One particular application of the communication method is a KVM switch system where the KVM switch acts as the master and the computers connected to the KVM switch act as slaves.

摘要： A video data recoding method suitable for recording computer sessions. Each video image frame is divided into multiple blocks. A server processes the video frames and transmits only changed blocks for each frame to a video log server. The video log server stores the changed blocks with block indices in a data file. The video log server also maintains a virtual frame table which stores, for each block of the frame, the data location within the data file where the most recent occurrence of that block is stored. The virtual frame table is continuously updated as changed blocks are stored in the data file. The video log server further stores a snapshot file containing snapshots of the virtual frame table at predetermined time points, along with time stamps and a next changed frame location. The data file and the snapshot file are used to reproduce the video images.

摘要： A combination console module is described which enables a console to be used both as a local console for a local KVM switch and as a remote console for a remote network-enabled KVM (IKVM) switch. In a stand-alone configuration, the combination console module includes a control section, an analog-to-digital converter for converting analog video signals from the KVM switch to digital video signals, a digital-to-analog converter (DAC) for converting digital video signals from the network to analog signals, a video switch for applying either the input video signal form the KVM switch or video signals from the DAC to the console's display, and a network interface device. The keyboard/mouse signals from the console are processed by the control section and transmitted to either the KVM switch or the network. The combination console module can also be implemented by modifying a conventional IKVM switch by adding the DAC.

摘要： A system includes multiple KVM switches, multiple user consoles and a recording system connected via a network. Each KVM switch facilitates interactions between user consoles and selected servers connected its server ports. The KVM switch transmits keyboard, mouse and video data exchanged between user consoles and servers, and administrative data, to the recording system. The recording system records the keyboard, mouse, video and administrative data, and detects trigger events based on such data. Trigger events include predefined keywords, mouse operations, video images, user IDs and server IDs, or combinations thereof. When a trigger event is detected, the recording system automatically transmits monitoring information to an administrative console via the network. The monitoring information may include combined video data containing information about keyboard and mouse actions superimposed on desktop images. The administrative console may also request specific recorded data for review. The recording system may employ a master-slave configuration.

摘要： A method for image compression is described. The method compresses computer images for efficient transfer of consecutive compressed images through a network. The method comprises loading two consecutive images, fuzzy comparing the two consecutive images, calculating the total different number between the two consecutive images, and determining an encoding algorithm, such as run-length and delta-modulation (RLEDM) or JPEG, according to the total different number. The fuzzy comparison eliminates deviations caused by capturing errors. The RLEDM encoding algorithm of the invention only deals with image differences between the two consecutive images, including line pattern indexes and line patterns, and depends on a minimum encoding size rule to further determine the encoding algorithm, such as a direct encoding, a run-length encoding or a delta-modulation encoding. The method provides an improved encoding algorithm by using a strategy where different circumstances each involve adopting an optimum method to reduce a bandwidth requirement of networks.
