Digital Watermarking for TV "Coming of Age".The European Broadcasting Union “EBU” redirects here. For other uses, see EBU (disambiguation). The European Broadcasting Union (EBU; French: L'Union Européenne de Radio-Télévision ("UER") (EBU EBU European Broadcasting Union EBU English Bridge Union EBU Enterprise Backup Utility (Oracle 7) EBU European Boxing Union EBU European Board of Urology EBU Electronic Business Unit EBU Equivalent Billing Unit EBU Engine Build Unit ) reported significant progress towards the development of effective ways to protect the copyright of live broadcasts on digital networks. Philips, Thomson, Lucent Technologies and Tektronix each developed a system of "digital video watermarking" in response to requirements agreed with an EBU project group. The systems have been undergoing performance tests since last summer. "While none of the systems submitted completely met all the stringent requirements set by the group, the tests did show that digital watermaking is coming of age," the project group said in a statement. The need for a secure means of marking video and audio material is increasingly urgent at a time when digital technology enables perfect pirate copies to be made and distributed through a growing number of communications channels. The new technology -- involving the invisible marking of video sequences and a reader able to recognize data in real time from a digital signal could be of great use in intellectual property management, tracking and copy protection from production to transmission. The tests were carried out by the BBC BBC in full British Broadcasting Corp. Publicly financed broadcasting system in Britain.

Louis Cheveau, Head of Trans-mission Technologies at the EBU, said the tests had been valuable in showing how the systems might be improved. Feedback had been given to the manufacturers, whom he thanked for their cooperation. Tests on audio watermarking systems will take place at a later stage. |
