HD HDR Live broadcasting
Sony already offers a full range of 4K HDR production systems for movies and TV drama and for live broadcasting where Sony has established its “SR Live for HDR” workflow, a powerful system for the efficient and simultaneous production of 4K HDR and HD SDR.
In July 2016, the International Telecommunication Union published the ITU-R HDR-TV Recommendation, BT.2100-0. This standard presents two options for producing HDR images - Perceptual Quantization (PQ) and Hybrid Log-Gamma (HLG) - and opens the way towards wider adoption of HDR broadcasting.

At the same time, many customer are also looking to produce High Definition (HD) content in HDR, especially where migration from HD to 4K Ultra HD may still need some time.
Responding to this need, Sony is now providing a HD HDR capable solution for broadcasters in a number of areas:
Workflow
SR Live for HDR can support HD HDR- based simultaneous production of HD HDR and HD SDR in the same method as for 4K HDR. In the SR Live for HDR workflow, the camera’s output signal is converted into [S-Log3, BT.2020, HD HDR] as an intermediate format for production processes.

Once the image has been produced, the Sony HDRC-4000, HDR production converter unit is required to convert it to an appropriate HDR-capable transmission format, such as standardised HLG or PQ. The HDRC-4000 utilises original algorithms, including built-in AIR Matching (AIR refers to Artistic Intent Rendering), to accurately reproduce the image quality and colour determined during S-Log3 production — regardless of the transmission format used.
The “SR Live for HDR” production environment can include a multiplicity of subject types, devices, formats, and vendors. The system is capable of delivering extremely high-quality content as images are produced using the S-Log3 format and converted into the desired format for distribution or broadcast.

Acquisition
The following system cameras will all support S-Log3 and BT.2020 for SR Live for HDR and will add HD HDR capability via a firmware upgrade:
The HDC-4800 camera system
The HDC-4300 camera system
The HDC-P43 camera system
For the HDC-2500, an HKCU-2040, 4K HDR processor board provides both a 4K and HD HDR capability from its image sensor.

Recording and replay
The PWS-4500, 4K live server - supports HD S-Log3, HD HLG and 4K/HD PQ with a software update to v2.3.
Monitoring
The BVM-E171, HD OLED master monitor will support HDR through a new HDR monitoring license, BVML-HE171. The license gives users an option for implementing HDR according to their production needs and budget. Sony BVM-X300 and PVM-X550 are already HDR-ready for any resolution up to 4K, and the addition of HDR to the BVM-E171 brings HD HDR monitoring capabilities to new users including OB vehicles where space is limited.

Instant HDR Workflow
As the expanding need for HDR content continues, internet video platforms and professionals producing corporate or event content are paying more attention to the added value of HDR. They need to deliver content quickly, without compromising on imaging expression and quality of content. To meet this demand, Sony now offers HDR capability on the entry level handheld XDCAM camcorders, PXW-FS5 and PXW-Z150. Both feature HLG recording[1] for easy file-based workflows, whilst achieving the image quality of HDR. This simple workflow enables the shooting, editing and viewing of HDR content in HLG, without the need for additional color grading.

Camcorders
The Sony PXW-FS5 and PXW-Z150 will receive the additional HDR capabilities via a software update. For the FS5, HLG will be supported, in addition to S-Log3. The HLG[2] mode can be set-up quickly through the option of the newly added picture profile. HLG mode will also be supported in the PXW-Z150.
