In a move which could facilitate the transmission of high definition video content over wireless links, an industry group, which includes Intel and Samsung, has published a content protection method for the distribution of high definition content using the WirelessHD standard.
The group behind the WirelessHD standard has published an extension to the Digital Transmission Content Protection (DTCP) specification for the use of WirelessHD.
The group said DTCP permits both streaming and copying of high-definition content from device to device.
Earlier this year, WirelessHD announced DTCP as the content protection method of choice for WirelessHD transmissions. DTCP enables not only direct display, but also the distribution of high definition (HD) content. This content, whether from Blu-ray discs, satellite, cable, or Internet broadcast may be securely sent over WirelessHD signals.
"The use of DTCP enables both the wireless display of this content in the newest generation of LCD’s and plasmas and the managed copying of this content to digital video recorders (DVR) and portable media players (PMP)," said the WirelessHD group.
The supplement to the DTCP specification provides the technical details for the use of DTCP with WirelessHD-enabled consumer electronics and personal computing products.
This newly approved use of DTCP is based on satisfying the concerns of the Motion Picture Association of America (MPAA) and the major studios about unauthorized and illegal copying of protected content.
The WirelessHD group was formed in 2006 by Intel, LG Electronics, Matsushita Electric Industrial, NEC, Samsung, SiBEAM, Sony and Toshiba.
