  "description_excerpt": "The present invention relates to coding, transport and signaling of logos and icons in television and radio broadcasts, in particular, to apparatuses and methods for coding of logos and icons in television broadcasts, more particularly, for digital television and digital radio DRM in ATSC television broadcasts.\n\nThe ATSC standards are a group of standards provided by the Advanced Television Systems Committee (ATSC) for digital television transmissions. Details on the Data Link Layer Protocol employed by ATSC can be found in the respective standard, [1]: A/330:2022-03, “Link-Layer Protocol”, published 31 Mar. 2022. ALP (ATSC Link-layer Protocol) supports the encapsulation of IP packets.\n\nDigital Radio Mondiale (DRM) is a globally deployed radio broadcasting standard. It delivers full-featured digital radio services in a highly efficiently coded manner, together with advanced text and other data services, to make best use of available channel resources. In parts of the world where DRM is in use, it is highly desirable for a broadcaster to be able to create and transmit identical Multiplex Distribution Interface (MDI) streams both on radio broadcasting spectrum and on television spectrum that will be able to reach mobile and handheld devices efficiently, ensuring a consistent digital radio experience for consumers.\n\nDRM allows to transmit multimedia data with particularly low data rates by employing the technologies xHE-AAC (extended High Efficiency Advanced Audio Coding)/USAC (Unified Speech and Audio Coding) and Journaline.",
