Abstract: In one embodiment, a process determines a size of a video unit (e.g., frame) to transmit from a sender to a receiver across a communication channel for an associated video stream, and also determines an updated packet loss rate on the channel. In response, the process may dynamically determine both a number N of video data packets and a number M of forward error correction (FEC) packets to transmit for the video unit based on the size of the video unit, the updated packet loss rate on the channel, and an error resilience requirement for the video stream. In an illustrative embodiment, N and M are determined during transmission of the video stream through a look-up operation into a table indexed by the size of the video unit and the updated packet loss rate as co-indices, the co-indices co-indexing a pre-determined N and M pair.

Abstract: The invention provides improved methods and apparatus for control using field and control devices that provide a virtual machine environment and that communicate via an IP network. By way of non-limiting example, such field device can be an “intelligent” transmitter or actuator that includes a low power processor, along with a random access memory, a read-only memory, FlashRAM, and a sensor interface. The processor can execute a real-time operating system, as well as a Java virtual machine (JVM). Java byte code executes in the JVM to configure the field device to perform typical process control functions, e.g., for proportional integral derivative (PID) control and signal conditioning. Control networks can include a plurality of such field and control devices interconnected by an IP network, such as an Ethernet.

Abstract: A control system has blocks or other components that facilitate validation of their own replacements, e.g., downloaded via e-commerce transactions. The system includes first and second process control components. The first component is coupled to a third process control component, with which it transfers information, e.g., as part of an active or ongoing control process. The second component can be, for example, an update or other potential replacement for the first component. The first and/or second components can effect substitution of the second component for the first. More particularly, they can effect coupling of the second component for information transfer with the third component and decoupling of the first component from such transfer with the third component. Preferably, such coupling and decoupling occur while the process control system remains active.
