The DVB is to mark its 20th anniversary this autumn with a demonstration of DVB-T2 delivering a series of resolutions from 4K Ultra HD down to the smaller screen resolutions typically found in mobile devices.
Using DVB-T2 transmission, a 4K service utilising HEVC encoding, and mobile service will be delivered in a single 8MHz channel. This is enabled by DVB-T2’s featured use of Multiple PLPs (Physical Layer Pipes) that allow for the separate adjustment of the robustness of each delivered service within a channel to meet the required reception conditions. The PLP for the mobile service is compliant to the T2-Lite parameter set.
The DVB will also show CI Plus v1.4, which now supports IPTV. In addition to a standard broadcast, a TV display will receive IPTV via its Ethernet interface. A CI Plus module will receive the IP multicast and carry out the necessary processing for Conditional Access and interactivity.
It is envisaged that the new features of CI Plus v1.4 will permit the CI Plus module to provide traditional set-top box functionality.
