Streambox Introduces NODE 2 Media Playout Device

By | Enterprise Server, Streambox Chroma, Streambox Cloud Services, Streambox NODE, Streambox Platform Solutions | No Comments

NODE 2 is a small form factor media player device supporting ten programmable video channels made to integrate with other Streambox components for cost-effective viewing of high quality video in real-time, making NODE ideally suited for mobile or remote operations.

NODE enables remote viewing by key stakeholders in a cost-effective manner. During live productions, vital personnel such as directors and producers can get a real-time view from anywhere in the world. For post-production, activities such as color grading and review of dailies can be done collaboratively. In education, teachers can bring a real-time visual experience to students in remote locations. Complex procedures can be monitored for advisement by technical specialists in healthcare, law, engineering and other professions. For security, critical monitoring can occur from a remote facility.

The NODE Decoder/Player is able to deliver viewer the highest quality visual experience with consistent video streaming. It has Gigabit Ethernet and Wi-Fi for Internet connectivity and an HDMI 2.0b output for video displays.

NODE provides up to 10-bit color depth, is HDR ready, and displays video in resolutions up to 2K. To sustain such superior quality media, NODE supports streaming bit rates up to 20 Mbps using Streambox reliable transport network protocol. Playout can include up to 6 channels of uncompressed audio, with support for 5.1 surround sound as well.

NODE is designed to automatically “pull” live video from Streambox Cloud Services, Streambox Enterprise Server, or directly point-to-point from various Streambox encoders such as Chroma for live playout to connected high resolution screens and displays. NODE can be left running 24/7 and render streams in real-time as they arrive.

NODE keeps content secure as well by offering full encryption for live video. End-to-end encryption, with a symmetric key, forms a protective shield around the transport of valuable video content with no increase in stream latency.

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

By | 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.

Summary

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.

Streambox Chroma™ Supports Native Color Space

By | Streambox Chroma, Streambox Platform Solutions | No Comments

Streambox is pleased to announce Native RGB / XYZ support for Streambox Chroma rackmounts. Chroma is the latest rackmount model from Streambox with support for HD, 2K, 4K, 12G-SDI, Encryption, and other features tailored for post-production workflows and broadcast contribution. Chroma is an industry leader with ACT-L5 and support for 12-bit 4:4:4 coding.

We provide SDI signals in 12 or 10-bit RGB, 4:4:4 mode:

  • Native RGB or XYZ color space will be encoded natively, avoiding any color conversion. This is a unique feature of Streambox Chroma and is well suited for high color precision HDR/Rec. 2020 or DCI-P3 workflows in 12-bit, or for direct output to projectors.
  • DCI, Inter-component Color Transform (ICT), RGB transform — is well suited for DCI-P3 workflows. This provides more efficient encoding vs native RGB/XYZ with modest color precession cost. On the decoder side, DCI-ICT will be converted to 10 or 12-bit RGB. It can be used for lower bitrate 10-bit HDR work as well.
  • Supports Rec.709 Full range standard for FHD broadcast — is the most efficient color transform for episodic TV workflow. On the decoder side, the video coding will be converted back to RGB.

So ask yourself, why deal with transformation artifacts when you can edit and color code within the native colorspace?
