Sony HDRC-4000 Operation Guide - Page 3

Overview The HDRC-4000 HDR Production Converter Unit converts HDR video signals using the OETF standard. OETF supports several standards, including Sony's original S-Log3 curve, SMPTE ST 2084 (PQ) and ITU-R BT. 2100 (HLG), and supports mutual conversion between standards. The unit also features the AIR MATCHING (Artistic Intent Render Matching) function, which allows you to convert to any format, using HDR signal OETF mutual conversion, so that the "look" is correct on a display that supports that particular OETF standard format. Also, you can convert between SDR and HDR while maintaining an identical appearance using the Display Referred conversion function. (However, when converting from HDR to SDR, SDR output levels that exceed 109% are clipped at 109%, causing an overexposure.) In addition to HDR OETF conversion, it also supports simultaneous mutual conversion between HDR/SDR, 4K/HD, and 2020/709 color space for conversion of various signal formats. This unit also supports external reference sync signals, and can be operated as a video signal frame synchronizer. Features Various video signal format conversion support Supports simultaneous conversion of various signal formats. • HDRyHDR: OETF signal standard conversion • HDRySDR: Dynamic range conversion • 4KyHD: Resolution conversion • BT.2020yBT.709: Color space conversion In addition, the SDI signal input/outputs also support the following signal formats. • 12G-SDI / 6G-SDI / 3G-SDI Level-A / 3G-SDI Level-B / HD-SDI • 2SI/SQD/No division AIR MATCHING (Artistic Intent Render Matching) function This function performs OETF conversion of HDR signals that maintains the image reproduction (visual appearance) on the display. When AIR MATCHING is ON, the conversion is performed such that the image on a display connected to the input side has the same visual appearance as the image on a display connected to the output side. The OETF settings of these displays are set as the input/output OETF. When AIR MATCHING is OFF, conversion is performed faithfully for the OETFs (Opto-Electronic Transfer Function) configured for input/output. Whether the image reproduction on the displays is the same or not is not taken into account. Display Referred conversion This function performs conversion of SDR signals to HDR signals, HDR signals to SDR signals, and HDR signals to HDR signals that maintains the image reproduction (visual appearance) on the display. The black level, gamma, inverse gamma conversion, highlight creation, HDR De-Knee and other picture quality adjustment settings are fixed (OFF or 0.0). Simultaneous output of 4K and HD signals Simultaneously outputs 4K and HD signals as output video derived from a single input signal. The 4K output and HD output signal conversion settings can be configured independently. Dual system signal processing Equipped with a dual system (channel A, channel B) signal processing function. A 4K signal or HD signal can be freely selected for each input setting. Video input/output Inputs Channel A • 4K: Single-Link 12G-SDI, Quad-Link 3G-SDI/Single-Link 6G-SDI, Dual-Link 3G-SDI, Quad-Link 1.5G-SDI or HD × 4ch: 3G/HD-SDI • HD: 3G/HD-SDI Channel B 1) • 4K: Single-Link 12G-SDI, Quad-Link 3G-SDI/Single-Link 6G-SDI, Dual-Link 3G-SDI, Quad-Link 1.5G-SDI or HD × 4ch: 3G/HD-SDI • HD: 3G/HD-SDI 1) You can also select the channel A input signal as the channel B input. Outputs Channel A • 4K × dual system: Single-Link 12G-SDI, Quad-Link 3G-SDI/ Single-Link 6G-SDI, Dual-Link 3G-SDI, Quad-Link 1.5G-SDI or HD × dual system × 4-ch: 3G/HD-SDI • HD × single system: 3G/HD-SDI • HD monitor × single system: HD-SDI Channel B • 4K × dual system: Single-Link 12G-SDI, Quad-Link 3G-SDI/ Single-Link 6G-SDI, Dual-Link 3G-SDI, Quad-Link 1.5G-SDI or HD × dual system × 4-ch: 3G/HD-SDI • HD × single system: 3G/HD-SDI • HD monitor × single system: HD-SDI External reference sync signal The output signal can be synchronized to an external reference sync signal (HD tri-level sync or SD sync). The following sync signals are supported. NTSC, PAL, 1080/59.94i, 1080/50i, 1080/23.98PsF, 1080/ 24PsF The unit is also equipped with a frame synchronizer function allowing it to operate as a frame synchronizer. If an external reference sync signal is not input, the output can be synchronized to the channel A input signal. Operation without an external reference sync signal, and input only on channel B is not guaranteed. Supported signal formats 4K: 2160/59.94P, 50P, 29.97P, 29.97PsF, 25P, 25PsF, 24P, 24PsF, 23.98P, 23.98PsF HD: 1080/59.94P, 59.94i, 50P, 50i, 29.97PsF, 25PsF, 24PsF, 23.98PsF (Input only) 720/59.94P, 50P 12G/6G-SDI input/output support 12G/6G-SDI Single-Link signals are supported for 4K signal input/output. 3
