NEWS RELEASE

APPEALS COURT RELEASES DECISION IN PREVIOUSLY DECIDED PATENT

INFRINGEMENT CASE BETWEEN SEACHANGE & C-COR

MAYNARD, Mass., June 29, 2005 – SeaChange International (Nasdaq:SEAC) announced that the United States Court of Appeals for the Federal Circuit issued its decision in one of the SeaChange/C-Cor (as the successor to nCube Corporation) patent infringement cases.

The decision reversed the September 2000 finding by the United States District Court of Delaware that C-Cor’s MediaCube-4 product infringed SeaChange’s patent (Patent No. 5,862,312), and remanded certain issues back to the District Court. No costs or awards were granted to either SeaChange or C-Cor. Damages had never been determined in the original case and the decision will have no effect on the Company’s financial statements.

“We don’t believe that this decision will have any impact on SeaChange’s future opportunities in the On Demand television market worldwide,” said Bill Styslinger, president and CEO, SeaChange International. “Our On Demand system is being used to stream more video every month than any other system provider. We will continue to make significant investments in technology development to ensure that our customers will continue to have leading edge, reliable and cost effective solutions.”

An appeal in a second patent infringement case between SeaChange and C-Cor is still pending.
