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.

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.

GEM Hospital & Research Center Streams Live with Streambox 4K

By | Avenir, Avenir Micro, Cloud, Apps & Software, Medical, Streambox 4k, Streambox Rackmounts, Success Stories, Video Transport | No Comments

GEM Hospital and Research Center provides surgical training via GEM Televersity (https://gemteleversity.com/), a program of the GEM Institute of Laparoscopy and Robotic Surgery which provides daily live surgical experience, and monthly CME deploying real-time video streaming. Prof. R. Venkatachalam of the Institute wanted to extend this live surgical training experience to participants of a conference-workshop about 160km (100mi) away (see Figure below).

Figure 1. Left: Auditorium of attendees of GEM workshop. Right: Real-time laparoscopic surgery with real-time, interactive, audio displayed on large, 40’x22’ LED displays

Streambox’s 4K OSX encoding software was used to capture and encode live video from Olympus 4K laparoscopic cameras and transported live video stream over a point-to-point IP network at a bitrate of 40Mbps to the conference facility where the video was played out on a large LED display. The video end-to-end latency was very short at about 0.8 to 1.2 seconds which was ideal for real-time training of surgical procedures over IP based networks to remote locations.

Prof. R. Venkatachalam commented that “the conference was great with live surgeries from 100 miles away … It so happened we launched 4K streaming on ‘The World Audiovisual Day’.”

Streambox 4K Encoder is powered by Streambox ACT-L3 Codec that produces exceptional color depth and accuracy used in Broadcast and in Film Post Production industries. ACT-L3’s more efficient encoding and wider color support provides a high quality live video for large displays making it ideal for medical training.

For low latency reliable video transport over IP networks, Streambox has integrated into the Streambox 4K Encoder reliable LDMP (Low Delay Multi-Path) network transport protocol.

Streambox video transport products are particularly well suited for use in live video medical training; either onsite or at any remote location. There are three main opportunities when using live video for medical training: 1) Students can view an unobstructed closeup of the procedure, 2) Students can view team interactions and cooperation, and 3) Students can be guided through the procedure by audio comments from the team (including, if appropriate, comments and questions from the students back to the team).

Streambox offers many exciting approaches to deliver these opportunities. Our equipment is deployed in many medical institutions around the world.

Deployment:

  • Onsite Viewing
    Classrooms, conference rooms, study halls, libraries, and lecture halls are all great teaching locations to stream live procedures. In years-gone-by and on TV they had operating theatres where students could only imagine what was happening. In the 21st century, the student can see exactly what the surgeon sees.
  • Remote Viewing
    Since Streambox uses video transport over IP networks, live video can be streamed to any classroom in the world (as long as they have good internet connectivity). This can be accomplished via point-to-point or over the Streambox Cloud. Furthermore, the classroom could be on a student’s laptop with Streambox Media Player installed. Or the classroom could be on each student’s smartphone with Streambox’s Android and iOS Media Player installed – and each student could be in a different country.
  • Remote Consultation
    Using remote viewing, consults and critiques can take place from anywhere in the world – you don’t need the expert in your OR to get quality feedback.
  • Encryption
    Streambox encoders and decoders support AES 128-bit end-to-end video encryption ensuring that adherence to regulations on Protected Health Information (PHI) can be met. An AES 256-bit encryption option is available with separate license and US Federal restrictions.
  • Real Time Video
    Streambox transport codecs are so efficient that latency within a local network can be 500msec and over the internet around 2 seconds (depending on the settings, internet bandwidth, and location of the viewer). This low latency along with its high video fidelity are why Streambox products are used by major news networks and movie studios.
  • Remote Medicine
    Streambox remote encoders with cellular modem modules can provide live video streaming from field locations; e.g., streaming an ultrasound output to a regional medical center.

Equipment:

  • HD and 4K Rackmount Encoders and Decoders
    HD images are great for viewing procedures on monitors up to about 90 inches. 4K is great for anything above 90-inch monitors.
  • HD 2-Channel Synchronized Encoders
    2-Channel synchronized encoders (also known as 3D encoders) allows for synchronized views from 2 cameras. This is ideal for watching synchronized closeup and wide-angle views; e.g., a synchronized closeup of a surgical procedure and a wider angle of the surgical team.
  • HD Mobile Micro Encoders
    Mobile encoders are an economical way to have 1 or many cameras in the same or different locations. For example, one camera can be zoomed in for a closeup of the procedure while another 1 or 2 cameras can be simultaneously viewing the team’s interaction. Or you could have streams from every procedure/operating room.
  • Mobile Cellular Modules
    This allows the Micro encoder to be used from any location with cell/mobile connectivity. The opportunities are only limited by one’s imagination; remote ultrasound, emergency first-aid stations or field hospitals, medical rescues and situational awareness, patient visualization at the scene or within a mobile ambulance or helicopter.
