A new hybrid mobile broadcast technology platform could provide a solution to the current standoff between the mobile and TV sectors over a common approach to mobile broadcast standards. The system, which embeds an LTE-A+ video steam within a standard DVB-T2 broadcast signal, is about to be field-trialled.

The BBC has started its Ultra-HD closed trials from the World Cup tournament in Brazil. The BBC Research & Development department has partnered with Arqiva for the trials that will use the latest DVB-DASH profile IP.
The UHD production will be received in the UK from an H.264/AVC satellite contribution feed. For both DTT and IP we will be using Main Profile HEVC to compress the video to distribution bitrates that can be sustained within a DVB network and a super-fast broadband line. The frame rate being used is 59.94Hz as that is the standard in Brazil.
The DTT trial will be transmitted from Crystal Palace (London), Winter Hill (Manchester) and Black Hill (Glasgow). The transmissions are just starting up now. As we are using the same T2 modulation parameters that are used for HD multiplexes the signal can be received on current consumer equipment, I’m not aware of any equipment which can decode the video. Though some existing HD models may tune the service and decode the audio.
The stream will use the latest DVB-DASH profile and is geo-IP locked to the UK only.

The DVB (Digital Video Broadcasting) group is seeking an expanded role to unify global standards for multiscreen services, while also ending the historical regional fragmentation in digital terrestrial transmission.
Emerging multiscreen services are being held back by fragmented standards, particularly over interaction between companion screens and linear broadcast services. At an IBC press conference the DVB said it wanted to act as a unifying force both in digital terrestrial transmission and companion screen interaction.
So far companion screen applications have grown up around many different proprietary technologies and are ripe for standardization, according to Nick Wells, vice chair of the DVB Technical Committee. “I expect to see broadcast and IP networks working together and here the DVB has a huge amount to offer,” said Wells.

The DVB Project is pleased to announce that its Steering Board today approved the Commercial Requirements for a second 3DTV delivery system. Termed ‘Service Compatible’, the second system is a solution required by content deliverers that enables the 2D and 3D versions of a programme to be broadcast within the same video signal, so that new 3D televisions and next-generation STBs can receive 3D programmes, while consumers with existing 2D HDTV receivers and set-top boxes can watch the 2D version. This 2D picture will probably be either the left or right image of the ‘stereo pair’.

A significant step in the road to Ultra High Definition TV services has been taken with the approval of the DVB-UHDTV Phase 1 specification at the 77th meeting of the DVB Steering Board. The specification includes an HEVC Profile for DVB broadcasting services that draws, from the options available with HEVC, those that will match the requirements for delivery of UHDTV Phase 1 and other formats. The specification updates ETSI TS 101 154 (Specification for the use of Video and Audio Coding in Broadcasting Applications based on the MPEG-2 Transport Stream). Another specification to gain approval from the Steering Board was the MPEG-DASH Profile for Transport of ISO BMFF Based DVB Services over IP Based Networks. This specification defines the delivery of TV content via HTTP adaptive streaming. MPEG-DASH covers a wide range of use cases and options. Transmission of audiovisual content is based on the ISOBMFF file specification. Video and audio codecs from the DVB toolbox that are technically appropriate with MPEG-DASH have been selected. Conditional Access is based on MPEG Common Encryption and delivery of subtitles will be XML based. The DVB Profile of MPEG-DASH reduces the number of options and also the complexity for implementers. The new specification will facilitate implementation and usage of MPEG-DASH in a DVB environment. Via DASH Industry Forum

The SVC4QoE consortium has concluded its project to show how the combination of Scalable Video Coding (SVC) and Quality of Experience (QoE) technologies can improve mobile multimedia services using DVB-T2 transmission. SVC means the receive device can be given a base layer video stream and an enhancement layer.
A QoE monitoring probe inside the receive device was used to detect any deterioration in receive conditions so the decoder could respond, if necessary, by using the base layer only to ensure continued service.
