NovaStar HDR Master 4K Video Conversion
The HDR Master 4K is a video processor for converting SDR sources to HDR10 or HLG and converting HDR sources back to SDR. It combines format conversion with adaptive scaling, source cropping, layer masking and image flipping for stage, rental and fine-pitch LED display systems.
The original description identifies SuperView III scaling. The linked manufacturer specification describes the available interfaces and format limits; conversion results depend on the source content, settings and downstream display. Converting SDR does not recover original scene information that was never captured in the source.
| Parameter | Specification |
|---|---|
| Input card | 1 pluggable card: 1 × DP 1.2, 1 × HDMI 2.0 and 4 × 12G-SDI; up to six simultaneous 4K × 2K at 60 Hz inputs, subject to format limits |
| Output cards | 2 pluggable cards with the same synchronized picture: HDMI 2.0 + 4 × 10G optical ports, and HDMI 2.0 + 4 × 12G-SDI |
| HDR formats | SDR, HDR10 and HLG conversion; HDMI input explicitly supports HDR10 and HLG |
| HDMI output examples | 4K × 2K at 60 Hz or 8K × 1K at 60 Hz; maximum-width example 8192 × 1080 at 60 Hz; maximum-height example 1092 × 7680 at 60 Hz |
| Optical mapping | OPT1/OPT2 copy HDMI output data; OPT3 copies OPT1; OPT4 copies OPT2 |
| SDI mosaic | Input/output mosaic for supported 3G-SDI, HD-SDI or SD-SDI formats |
| Background / logo files | USB import; up to 10 background images with maximum width or height 8192 pixels, and 10 logos with maximum width or height 512 pixels |
| Monitoring / backup | Dedicated LCD monitoring screen; self-test, status monitoring and input hot backup |
| Control / synchronization | Gigabit Ethernet computer control; USB firmware and BKG/LOGO import; Genlock input and loop; CONTROL UI reserved |
| Power | 100–240 V AC, 3 A, 50/60 Hz; maximum power 120 W |
| Operating conditions | 0°C to +45°C; 10–85% RH, non-condensing |
| Dimensions / net weight | 482.6 × 442.5 × 50.5 mm; 7.5 kg |
Check Bit Depth and Color Sampling
The original Chinese specification, labelled with embedded software V4.1, gives these HDMI/DP format limits. The same document distinguishes forced source timings from selectable presets; a maximum format entry does not mean every preset is selectable on every interface.
| Parameter | Specification |
|---|---|
| 8-bit RGB / YCbCr 4:4:4 or YCbCr 4:2:2 | 4096 × 2160 at 60 Hz; 8192 × 1080 at 60 Hz with a forced source timing |
| 10-bit / 12-bit RGB or YCbCr 4:4:4 | 2560 × 1600 at 60 Hz |
| 10-bit / 12-bit YCbCr 4:2:2 | 3840 × 2160 at 60 Hz |
| YCbCr 4:2:0 | Not supported in the listed 8-, 10- or 12-bit modes |
HDMI supports HDCP 2.2/1.4, while DP is listed with HDCP 1.3. For the documented long-distance 12G-SDI input arrangement, NovaStar specifies CANARE L-4.5CHD+ UHDTV-SDI cable under 50 m. Do not generalize that distance to arbitrary cables or optical modules.
Frequently Asked Questions
Can HDR Master 4K convert SDR to HDR10 or HLG?
Yes. It converts SDR content to HDR10/HLG and supports conversion from HDR10/HLG back to SDR. Configure the output format for the receiving equipment and display.
Do the two output cards show different programs?
The linked specification says the two cards output the same picture synchronously. Their different connectors provide output options rather than two independent programs.
Does every color format support 4K at 60 Hz?
No. The linked format table allows 10-/12-bit YCbCr 4:2:2 at 3840 × 2160 at 60 Hz, but limits 10-/12-bit RGB or YCbCr 4:4:4 to 2560 × 1600 at 60 Hz. Check bit depth, sampling and timing together.
What are the four optical ports used for?
They carry copies of the HDMI output data. OPT3 duplicates OPT1, and OPT4 duplicates OPT2. They should not be counted as four independent picture outputs.
Can I import a background or logo from USB?
Yes. The processor stores up to 10 background images and 10 logos. The documented maximum width or height is 8192 pixels for a background and 512 pixels for a logo; consult the manual for file preparation and import.
