Color Fidelity Test for Streambox Chroma in Native RGB, XYZ Color and YCrCb 4:2:2 for SDR or HDR

By | 2K Rackmount, HD Rackmount, Streambox 4k, Streambox Chroma, Streambox Platform Solutions | No Comments

The Streambox Chroma rackmount half-duplex Encoder/Decoder with ACT-L5 codec is well suited for post-production editing and color correction workflows in SDR or HDR. The ACT-L5 codec supports Native RGB and XYZ color space, 10 and 12-bit color depth, and the 4:2:2 and 4:4:4 color profiles. The Streambox Chroma rackmount has been tested for color stability and fidelity and has met SMPTE 372 standard including HDR modes.

Native RGB vs DCI/ICT RGB Test

A color-bar software generator (Blackmagic 4K monitor, SDI out) was connected to a Streambox Chroma Encoder (with Blackmagic 12G Pro, SDI-in) which was connected to a Streambox Chroma Decoder via an IP network hub. The decoder output was to a Blackmagic 4K monitor. On the decoder, we read the SDI value averages before data is passed through the SDI out (after all conversions are complete). Findings:

Native RGB encoding does not perform any color transform and encodes RGB values natively. RGB ICT mode performs RGB transform to/from DCI ICT (compatible with DCI ICT, ISO/IEC 15444-1). Both modes are supported via Streambox Croma UI. Streambox Chroma supports both full and legal ranges.
Following test were performed in Full range mode.
• Native RGB has less errors than ICT (+1 in last 12-bit digit)
• Clipping for reserved SMPTE 372, 12-bit SDI values:
Software generated values 0-15 are clipped to 16 by hardware (base)
Software generated values 4080 to 4096 are mapped to 4079 by hardware (ceiling)

The 10 Bit 4:2:2 Chromatic Test for Rec.709/Rec.2020 (HDR)

A Streambox Chroma Encoder with Decklink 4K Pro was connected through a network hub to an identical Streambox Chroma Decoder.1 Source format: 1080p24. The encoder was set to Full 2K resolution, 10-bit color depth, 4:2:2 color profile, and Rec 709 color space. The decoder was in test mode. The table below shows that the color values were identical between the source and the decoder out.2 The values where stable with no vibration. Since no color space conversion is performed in 4:2:2 mode, the same result applies to Rec.2020 signal fidelity.


The Streambox Chroma rackmount Encoder/Decoder with ACT-L5 compression and support for Native RGB 4:4:4 and YCrCb 4:2:2 delivers color coding consistent with SMPTE 372 standards. Furthermore, these tests demonstrate that the measured colors before and after chromatic conversions were identical, making the Streambox Chroma ideal for color correction workflows including support Rec.709, DCI P3, Rec.2020, HDR10 PQ/HLG and Dolby Vision.

2018 will be an exciting year for Streambox, with many new product innovations including the new, more efficient ACT-L5 codec. We have released a number of new products and services for video professionals. Products like, the new Chroma RackmountVideo EncryptioniOS Media Player, and the upcoming NODE 2.

Streambox’s ACT-L5 compression codec provides the 12-bit, RGB 4:4:4 color profile required for cinematic, episodic, and commercial color grading and editing. Post production professionals can do native 12-bit RGB to simplify overall workflow.

Producers, engineers, and colorists can now deliver real-time services with a bottom line advantage for color correction, remote editorial, and final review. In addition, users can upgrade Streambox Chroma rackmounts with add-ons such as DCI 4K/2K with 4:4:4 RGB color in 12 or 10-bit and 12G-SDI, HDR, uncompressed audio, and native support for Rec.2020, DCI P3, and Rec.709.

Streambox iOS Media Player is a software decoder for iPad and iPhone devices. IP video is received from Streambox encoders or from Streambox Cloud services. It is well suited for point-to-point or point-to-multipoint streaming with streams being pushed (routed to) or pulled from Streambox Cloud Services. IPad screens are designed to handle P3 color space natively and provide perfect color match for POST reviews.

The Streambox Multi-Channel Sync Decoder can receive up to 8 video streams that will be synchronized to a user selected master stream and output as genlocked and synchronized 8 HD-SDI streams. The Decoder can receive streams from any of the Streambox Avenir line: Micro, Drone, Mini 4; or the Chroma 4K/2K/HD DCI Rackmount Encoder.
