DVB recently updated its audio-visual coding specification, adding support for High Dynamic Range (HDR), Higher Frame Rates (HFR) and Next Generation Audio (NGA). You can now learn all about the new features in a webinar by the editor of this impressive specification, Virginie Drugeon (Panasonic) on January 18th, 2017. The webinar and Q&A time should take around 1 hour. You can send your questions by the Webex chat function during the webinar and questions will be answered in a few blocks during the webinar.
The specification update has been published as BlueBook A157 and will be passed to ETSI for formal publication as TS 101 154 v2.3.1.
High Dynamic Range (HDR) significantly increases the contrast ratio and results in pictures with more ‘sparkle’. The DVB HDR solution supports Hybrid Log Gamma (HLG) and Perceptual Quantizer (PQ) transfer functions. Furthermore, the new specification defines Higher Frame Rates (HFR), offering sharper images of moving objects by going beyond the current 50/60 frames per second. When it comes to audio, DVB has added the latest Next Generation Audio (NGA) schemes to provide immersive and personalized audio content using object- or scene-based coding.
