UHDTV System Parameters for Programme Production(STD-B56 Ver.1.0 March 2013)This standard specifies the system parameters of the UHDTV for programme
production system. It is a subset of ITU-R BT.2020 and its parameter values are
selected to meet program production for a broadcasting service in Japan.
English version is not available.

1.2GHz/2.3GHz-Band Portable OFDM Digital Transmission System forTelevision Program Contribution(STD-B57 Ver.1.0 December 2013)This standard specifies the OFDM digital transmission system with SISO (Single-InputSingle-Output) mode for the FPU (Field Pickup Unit), a kind of portable radiotransmission equipment for television program contribution in 1.2GHz/2.3GHz-band.
English version is not available.

Interface for UHDTV Production Systems(STD-B58 Ver.1.0 March 2014)
This standard specifies the interface for UHDTV equipment that meets UHDTV
System Parameters for Programme Production (ARIB STD-B56).
English version is not available.

Three-dimensional Multichannel Stereophonic Sound Systemfor Programme Production(STD-B59 Ver.1.0 March 2014)
This standard specifies the three-dimensional multichannel stereophonic sound systemwith 22.2-channel (22 main channels plus 2 low frequency effect channels, that arearranged on three layers). This system is intended to be applied to the sound system ofthe UHDTV.
English version is not available.

Study for Broadcasting System
1

Quality Evaluation Method for Broadcasting(1) Flat Display Image Quality Evaluation
The experiment on the relationship between appearance and screen size isconducted. It is observed that appearance does not depend on the screen size, andthat appropriate environment needs to be fixed at the time of evaluation.
(2) Sound Quality Evaluation
Regarding the evaluation of the next generation 3D multi-channel sound system,
the methods for the subjective assessment that stipulated in ITU-R BS.1116 is
being studied.
The proposed amendments to the method for the subjective assessment ofintermediate tone quality (MUSHRA method) in ITU-R BS.1534 are discussed andcomments are sent to Rapporteur group of ITU-R WP6C.

2

New Technology for the Next-generation Broadcasting System(1) Future 3D Television
The research and study are conducted for the future glassless 3D television system.
As an initial step, the current status of the stereoscopic 3D system is surveyed.
(2) Hybrid broadcast broadband service
A discussion on hybrid broadcast broadband service is in progress.
(3) Transmission Technology for Next-Generation Digital Broadcasting
The study is conducted on transmission technologies and transmission systems forthe television program contribution that exceed current transmission bit rate.

Digital Broadcasting Systems(1) Multiplexing Technology
Multiplexing of UHDTV and V-low multimedia broadcasting are being studied.
A discussion on the multiplexing for satellite UHDTV broadcasting is in progress
focusing on MMT/TLV system and extended MPEG-2TS system.
(2) Video Coding Technology
The subjective evaluation experiment is conducted to estimate bit rate required toobtain broadcast quality when encoding UHDTV video using HEVC (HighEfficiency Video Coding).
The work is in progress to make operational guidelines and to find constraints ofencoding parameters in case of using HEVC.
(3) Audio Coding Technology
Regarding the input format and coding technology for UHDTV audio, the technicalspecification and the method for experiment are discussed.
(4) Data Broadcasting
The study is focused on service image and use case of the data broadcasting onUHDTV (4K/8K).

The access control technology of UHDTV is studied. Both the MMT/TLV method
and the extension MPEG-2 TS method are in discussion with respect to scramble
subsystem.
In addition, it is concluded to adopt a triple key method, which is same as thecurrent broadcasting, for the access control functions of related information
subsystem.

The operational issues regarding Operational Guidelines for Loudness of Digital
Television Programs (TR-B32) are in discussion. Responding to the question fromouter organization, it is confirmed that TR-B32 is developed to control audio
programme by average loudness level and true-peak level. Since mode of short term
loudness is out of the scope of TR-B32, the specification for indicating meter
designed in ITU-R BS.1771 is treated as a reference and annexed to TR-B32.

2) Scrambler be not applied
3) Bit rate be 10.692Gbps
4) The 8B/10B synchronization code should be “EAV / SAV rewrite”
5) Jitter provisions be the same as the ST435 to match SMPTE standard
6) Placement of 24 core of 10G link be fixed7) A format that can be transmitted within 12-core, should be arranged bystuffing link-signal to make 12-core receiver and transmitter be available
