Future Video

New video formats and aspects of quality improvement – with focus on new codecs and UltraHD requirements.


Immersive video promises to immerse completely in the action in front of the screen or with the help of data glasses. Technologies for this are Ultra HD, Virtual Reality, Augmented Reality and Mixed Reality. The IRT deals with future video displays and formats as well as with the production requirements and develops recommendations for the parameters and quality improvement of the entire production and distribution chain. The focus is on new codecs and the requirements for UltraHD.

UHD – From the camera to the display

UHD, the television of the future, deals with more pixels, more images, more dynamic, more colours. UHD is not just about increasing the resolution (4x HD resolution). By expanding the colour space (Wide Color Gamut WCG), the contrast range (High Dynamic Range HDR) and the image refresh rate (High Frame Rate HFR), better pixel quality can be achieved. Current TV sets for viewers already support all UHD features, with the exception of HFR.

IRT conducts investigations into the composition of UHD production and distribution chain to support the broadcasters. In doing so, options for action and added values of individual aspects of UHD are recorded and evaluated, and recommendations are given regarding production, mezzanine and distribution codecs (broadcast and OTT) of suitable parameterizations. Furthermore, conversion procedures for the mentioned aspects of UHD will be investigated and recommendations derived for the operation of legacy HD distribution channels using UHD content and the use of HD material in UHD productions (e.g. archive material).

Object-based video

Individual objects of a video production are captured using a temporal or content-related segmentation of video content. In this way a (partially) fully automated processing for new, mainly mobile and small-format terminal devices is offered, as well as interaction possibilities with individual objects are created.

Objects can be determined both by recording temporal or spatial arrangements of, for example, foreground/background and insertions in the production, by suitable three-dimensional recording techniques, or by the subsequent analysis of video content. The use of segmented videos is therefore expected to open up completely new possibilities for use in production as well as for the viewer's forms of presentation.

As part of object-based media production, IRT develops solutions by using open standards and in a close coordination with broadcasters and standardization committees.

Codecs in comparison

The technical quality of the encoders, transcoders and decoders used in the production chain is becoming increasingly important. Furthermore, a cascading of such devices has an impact to the quality.
IRT investigates and evaluates new codecs and develops planning parameters for production platforms and program broadcasting with the aim of supporting broadcasters and equipment manufacturers to rely on the right technology trend on the one hand and to achieve the desired technical quality levels efficiently on the other.
In this context, the IRT evaluates codecs that are preferred in acquisition and production (AVCUltra, XAVC, etc.) as well as the video coding standard High Efficiency Video Coding (HEVC), which is used especially in contribution and distribution.

Test Services

Regarding the quality of encoders, transcoders, converters, decoders, cascading of codecs and conformity to standards, IRT offers test services in its own test studio, with (U)HD servers for uncompressed video:

  • Distribution encoder tests for image quality from SDTV up to 2160p and video coding standards HEVC, H.264 and MPEG-2 (anonymous comparison on demand)
  • Conformity tests regarding DVB signalling
  • Contribution encoder tests for their image quality in UHD, HD, SD and the MPEG-2, H.264, H.265 and JPEG 2000 standards
  • Converter tests for up, down and cross conversions
  • Subjective tests by Experts Viewing using current displays (if required also subjective tests according to ITU-R BT.500)
  • Objective tests using PSNR calculation with subsequent subjective evaluation
  • Customer-specific consulting regarding the optimal approach for quality tests

Display technology

As an electro-optical interface between electronics and humans, displays play a key role in the entire television production process, which has led to a change in the world of display technology in recent years. In the meantime, all manufacturers offer flat-panel displays for professional use. High-end consumer appliances are also entering the professional market and new models are being presented at ever shorter intervals.
In order to provide broadcasters with targeted advice on the use of modern display technology in the studio, IRT follows developments on the display market, carries out various measurements on playback devices (colorimetric measurements and evaluation of the quality of playback devices for television, measurement of resolutions, measurement of noise generation) and, above all, investigates the suitability of flat-panel displays in the production environment (e.g. as reference, control or observation monitors).

Test Services

IRT offers the testing of displays for compliance with standards and technical requirements in its own test lab. Among others, the following parameters can be tested:

  • Brightness and colour temperature
  • Transfer function
  • Uniformity of luminance and colour
  • Contrast ratio and black level
  • Colour reproduction
  • Behaviour of the contrast ratio, the black level and the colour change of the white point, when viewing from different angles
  • Acoustic noise
  • SDI interface
