The DVB steering board has given its approval to a new set of commercial requirements that will be built on top of the existing CI Plus standard.
Version 1.4 includes support for dual stream operation with a single module, intended for where there is a dual tuner PVR host, and support for DRM protected DRM delivered content.
Other new features include CI Plus browser extensions, additional URIs (Uniform Resource Identifiers), signalling and extensions and clarifications for module applications running on host middleware.
The move follows an agreement with CI Plus LLP that the DVB should take on future development of the CI Plus specification. The work is expected to take a year, after which it is expected to be adopted by CI Plus LLP.
CI Plus adds additional security features to the DVB common interface, allowing televisions and other suitably equipped devices to add pay-TV services without the need for a set-top box.
In a related development, the DVB said that a letter of agreement confirming a liaison between the 3D@Home Consortium and DVB was signed on November 4, 2011. The purpose of the liaison between the two consortia is to encourage the development of standards for 3DTV, to share knowledge about 3D viewing, and to ensure that their work is complementary.
