Language	English
Pages	142
Description	The current version of the UHD Book Volume 2.2 complies with the latest DVB-I specifications (A177r7, Revision 7) and HbbTV (rel. 2.0.5). Furthermore, it reflects the most recent AGCOM resolutions 294/23/CONS, 259/24/CONS, and 250/25/CONS regarding accessibility and visibility. Certain specific parts have been removed compared to previous versions, in particular the DRM annexes: PlayReady and Widevine support aligned with HbbTV; Marlin and Nagra DRM have been discontinued due to lack of market demand; MPEG-2 video decoding is no longer required following its deactivation in Italy on 20/12/2022. AFD support is no longer required in an entirely 16:9 environment; support for hierarchical DVB-T modulation has been abandoned; the compliance notation now refers to ETSI drafting rules; the “sunrise” period and accessibility are addressed in new dedicated clauses; Table 46 (national TS_ID in use) has been updated.
