    摘要： A video transmitter can adaptively alter its transmission rate to plural receivers which receive video via multicast transmission. While the transmitter is initially in the “no tuning state”, the need for a video tune-up state change can be determined. If so, then the state can be set to “tuning up” and the retransmission rate can be increased. However, if “tuning-up” is no longer required, the state returns to the “no tuning” state” Likewise, the need for a video tune down slate change can be determined and the retransmission rate can be decreased. However, if the state is set to “tuning down” and “tuning down” is no longer required, the state is set such that “tuning down” is no longer true and the state returns to the “no tuning” state.

    摘要： A digital rack interface pod (DRIP) that is able to establish a communications link between a remote access appliance and a server having a USB port and a video port, to facilitate a keyboard/video/mouse (KVM) session between the server and the appliance. The DRIP is also able to establish a communications link between the appliance and an Ethernet port of the server that is associated with a service processor (SP) of the server. In this manner the DRIP is able to route data from the SP of the server to the appliance as well as communications from the appliance to the SP Ethernet port of the server. The DRIP is able to intelligently determine which packets of information received from the appliance are intended for the SP Ethernet port of the server and routes those packets to the SP Ethernet port of the server. The DRIP also automatically monitors and dynamically reassigns its two Ethernet ports as needed so that whichever one of its two Ethernet ports it discovers a connection with the appliance on will be the port that it continues using to communicate with the appliance.

    摘要： A video transmitter can adaptively alter its transmission rate to plural receivers which receive video via multicast transmission. While the transmitter is initially in the “no tuning state,” the need for a video tune-up state change can be determined by calculating if the current generated A/V retry transmission rate is greater than the video tune-up start threshold and if it was triggered more than the video tune-up interval ago. If so, then the state can be set to “tuning up” and the retransmission rate can be increased by the video tune-up step, as shown in FIG. 7. However, if the state is set to “tuning up” and it is determined that the current generated A/V retry transmission rate is greater than the video tune-up stop threshold, then “tuning-up” is no longer required, and the state is set such that “tuning up” is no longer true such that the state returns to the “no tuning” state. Likewise, the need for a video tune-down state change can be determined by calculating if the current generated A/V retry transmission rate is greater than the video tune-down start threshold and if it was triggered more than the video tune-down interval ago. If so, then the state can be set to “tuning down” and the retransmission rate can be increased by the video tune-down step. However, if the state is set to “tuning down” and it is determined that the current generated A/V retry transmission rate is less than the video tune-down stop threshold, then “tuning-down” is no longer required, and the state is set such that “tuning down” is no longer true and the state returns to the “no tuning” state.

    摘要： A group identifier can be used to assign blocks of addresses to the various groups of transmitters and receivers communicating on a single wired LAN. For example, a form-based control (e.g., a text entry box, a radio button, a drop-down box, a list box or a combo box) can be provided in a form controlled by a web server internal to the transmitter. The form enables a configuring user to specify to which of multiple (e.g., 4) groups a transmitter and its receivers (e.g., specified by MAC address) are going to belong. The transmitter thereafter can select its own IP address (based on the group number) and the known range of IP addresses available for its receivers. Once the IP addresses have been assigned to the transmitter and receivers, the transmitter can send (1) control data to the receivers at their receiver-specific IP addresses and (2) AV data to their multicast address.
