3. Methodology for performance evaluation of digital television broadcasting beyond 1st generation DTTB systems, including assessment of coverage
Some countries who have completed the transition from analogue to digital terrestrial broadcasting are considering a further transition to 2nd Generation Digital Terrestrial Television systems.
Studies to date undertaken on deployments of 2nd generation digital terrestrial television broadcasting do not meet the valuable records achieved in ITU-R Reports BT.2035, BT.2137 and BT.2143.
The paucity of similar documents to those developed in the transition to 1st generation digital television broadcasting is possibly due to the formative state of the implementation of 2nd generation digital terrestrial television systems.
In response to advancing reports on DVB-T2 deployments beyond the existing equipment trials this contribution proposes that Working Party 6A establishes a Methodology for evaluation of 2nd generation digital television broadcasting, including assessment of coverage

4. Bit rate and bit depth requirements for delivery of UHDTV television pictures
Recommendation ITU-R BT.2073 specifies the use of the High Efficiency Video Coding (HEVC) standard as per Recommendation ITU-T H.265 ISO/IEC for ultra-high definition television (UHDTV) and high definition television (HDTV) broadcasting.
- SD at 860 kbits/sec
- HD at 2703 kbits/sec
- UHD at 23,922 kbits/sec
HEVC encoding was done using x265 version 1.2, and all quality measurements were done using the peak signal-to-noise ratio and structural similarity index.
HEVC Main (8-bit) profile to allow quality matching with H.264 and MPEG-2 8-bit encoding.

5. - full range coding – 12 bits - luminance levels for skin tones
Characteristics of the application of high dynamic range parameters and specifications to UHDTV picture formats
Ongoing studies
- full range coding – 12 bits
- luminance levels for skin tones
- image format signaling - colorimetry values
- PLUGE test signals
- Mapping to display with limited brightness range

6. DRAFT OP73 UHDTV QUALITY SPECIFICATIONS FOR DELIVERY OFHDTV PROGRAMMES
This document recommends the format and quality of the video and audio associated with ultra-high definition (UHDTV) formats for television programme material delivered to the Australian terrestrial television broadcast industry in high definition (HDTV) format. This document deals with the UHD-1 specification (3840 horizontal pixels x active lines) and Standard Dynamic Range picture characteristics.

7. DRAFT OP74 UHDTV PRODUCTION FORMATS FOR DELIVERY OF HDTV COMMERCIALS
This Operational Practice provides specifications for UHDTV production of video and audio associated with the delivery of HDTV commercials and recommends the formats and quality for file delivery to the Australian terrestrial television broadcast industry. It incorporates recommendations for the down conversion of UHDTV signal characteristics in accordance with Recommendation ITU-R BT.2020.
N.B. the Australian terrestrial television broadcast industry seeks file delivery to the Australian terrestrial television broadcast industry with picture characteristics with Standard Dynamic Range.
