HDR Industry Challenges
01 Inconsistent standards and different display effect
Though multiple HDR technical standards coexist, no implementation solution exists on the device side. The compatibility between standards is poor, and is unable to meet the requirements for the adaptation, certification, and testing of mainstream devices.
02 Fragmented ecosystem and high patent fees for certain standards
High costs across the value chain, and limited device support has hindered the development of the ecosystem.
03 Difficult to produce and lack of UHD media sources
Insufficient supply of high-quality media sources, few UHD channels, unsatisfactory video length, and inadequate 8K sources have suppressed user demand for UHD video.
HDR Vivid Industry Ecosystem
01 Defining UHD PQ
HDR Vivid publicly defines the HDR process of UHD video presentation and processing in the form of group standards, ensuring that high-quality video is faithfully reproduced. Based on the existing HDR, dynamic metadata is added to provide more accurate dynamic range mapping for the display device, so as to restore the original artistic effects of the HDR content to the greatest possible extent. In addition, HDR Vivid embeds dynamic metadata from front-end production, ensuring that the device computing power can be realized, and that processing effects are controllable and predictable. Compared with the existing private HDR technology within the industry, HDR Vivid represents a more open and universal technical standard and solution. HDR Vivid is more suitable for all parties, spurring industry-wide deployment via open technology and enhanced security.
02 E2E Media System Standard
HDR Vivid offers an E2E media system standard to ensure backward compatibility.
Existing UHD HDR videos can be smoothly upgraded to HDR Vivid videos, lowering the technical implementation threshold. Dynamic metadata from HDR sources is extracted and encoded in the front-end production phase, and no modifications are required during transmission. Adaptation is performed based on dynamic metadata on the device side.
03 Implementation and Adaptation
The comprehensive HDR Vivid device-side implementation solution has helped facilitate the evolution to high-standard images.
Standard compliance test and certification are conducted on devices, such as TV, set-top boxes (STBs), and codecs that directly affect the display quality, according to strict certification specifications.

04 Batch Production and Broadcasting Tools
UHD videos can be produced in batches, using the automated and manual UHD video production and broadcasting tools.
Only dynamic metadata generation is added to the production phase, without changing the original HDR10 and HLG HDR production processes. The easy-to-use graphical user interface (GUI) is used to help producers manually debug the dynamic metadata. An automatic dynamic metadata generation tool is provided to support batch production, and reduce development costs.
