Networking technology firm Lucent has reignited a patent battle with Microsoft over the use of a specific video decoding technique in the Xbox 360 console, which Lucent claims infringes in a patent that it has held for over a decade.
According to Lucent, the MPEG2 decoder used by the Xbox 360 for some of its video functionality infringes on US patent number 5,227,878, which dates from mid-1993 and describes a method for "adaptive coding and decoding of frames and fields of video."
