The DVB is to demonstrate the delivery of HEVC-encoded ultra-high definition and mobile TV in a single DVB-T2 channel at next week’s Broadcast Asia show, co-located with CommunicAsia in Singapore.
DVB-T2 will be used to deliver a range of resolutions from UHD down to the smaller screen resolutions for mobile devices including smartphones in a single 8MHz channel.
The UHD service, with content encoded by Envivio, will be transmitted using a portable Dektec modulator and is received and displayed on a 55-inch UHDTV from Sony with built-in HEVC decoder. The mobile service will be received on an Aprotech Walka handheld TV with 7-inch viewing screen as well as on Samart i-Mobile smartphones and tablet, which are some of the first commercially available mobile devices with embedded DVB-T2 receivers.
The mixing of DVB-T2 multiple services in one multiplex is enabled through the use of Multiple PLPs or Physical Layer Pipes, a feature of DVB-T2 that allows for the separate adjustment of the robustness of each delivered service within a channel to meet the required reception conditions, according to the DVB.
Separately, satellite operator Eutelsat is to launch a new 4K demo channel for the Asian market at CommunicAsia.
Eutelsat is working in partnership with media services provider ST Teleport to launch its 4K TV channel on the Eutelsat 70B satellite that reaches across south-east Asia and Australia.
Content will be encoded in HEVC by Ateme and Thomson Video Networks at 50 frames per second with 10-bit colour depth and will be displayed on a Samsung 65 inch panel at the show. The channel will be receivable via 4K TVs equipped with DVB-S2 modulators and HEVC decoders.
