Latest Patents

One of Kevin's latest patents is titled "Instrumentation of MPEG-2 transport streams for testing network performance." This invention discloses a method and apparatus for testing and measuring the performance of a network that delivers multimedia. The multimedia source is divided into data packets according to a packetizing standard. Each data packet includes a header and a payload containing a portion of the multimedia. N data packets (N>0) are grouped together into a packet bundle, and instrumentation is inserted into the header of at least one data packet within the packet bundle. This instrumentation includes information used to determine performance characteristics of the network.

Another significant patent is "Detecting media rate for measuring network jitter." This invention provides a method and apparatus for measuring network performance. A stream of packets of encoded data is sent by a transmitter across a network and received. The stream includes (n+1) packets having transmittal timestamps from a clock local to the transmitter, where n is an integer greater than or equal to one. An (n+1) transmittal timestamp and an n transmittal timestamp are determined. A value is calculated based on these timestamps, which corresponds to the size of a virtual buffer needed to store the packets during a measurement interval. This value is then used to determine a performance measure for the network.
