ISDB-T International standard is currently adopted by most Latin America countries. To support interactive applications in Digital TV receivers, ISDB-T defines the middleware Ginga. Similar to Digital TV, Digital Radio standards also provide the means to carry interactive applications; however, their specifications for interactive applications are usually more restricted than the ones used in Digital TV. Also, interactive applications for Digital TV and Digital Radio are usually incompatible. Motivated by such observations, this report considers the importance of interactive applications for both TV and Radio Broadcasting and the advantages of using the same middleware and languages specification for Digital TV and Radio. More specifically, it establishes the signaling and definitions on how to transport and execute Ginga-NCL and Ginga-HTML5 applications over DRM (Digital Radio Mondiale) transmission. Ministry of Science, Technology, Innovation and Communication of Brazil is carrying trials with Digital Radio Mondiale standard in order to define the reference model of the Brazilian Digital Radio System (Portuguese: Sistema Brasileiro de Rádio Digital -SBRD).

“…Several works have already been implemented to make audiovisual content accessible to people with some sensory impairment. For example, there is audio description for visually impaired people, subtitles, Teletext and even sign language for people with hearing impairments [10][11][12][13][14]. Some works combine accessibility in TV with virtual reality (VR) and Multi-Screen TV Experiences taking it to different applications such as culture and sports [15,16].…”

Immersive video is changing the way we enjoy TV. It is no longer just about receiving sequential images with audio, but also playing with other human senses through smells, vibrations of movement, 3D audio, feeling water, wind, heat, and other emotions that can be experienced through all human senses. This work aims to validate the usefulness of an immersive and interactive solution for people with severe visual impairment by developing a haptic glove that allows receiving signals and generating vibrations in hand, informing about what happens in a scene. The study case presented here shows how the haptic device can take the information about the ball’s location in the playing field, synchronized with the video reception, and deliver it to the user in the form of vibrations during the re-transmission of a soccer match. In this way, we take visually impaired people to live a new sensory experience, allowing digital and social inclusion and accessibility to audiovisual technologies that they could not enjoy before. This work shows the methodology used for the design, implementation, and results evaluation. Usability tests were carried out with fifteen visually impaired people who used the haptic device to attend a soccer match synchronized with the glove’s vibrations.

Although the closed caption broadcasting is provided for almost the whole broadcast time in Korea, the sign language interpretation is not. By translating the closed captions, it is possible to provide three-dimensional (3D) sign language translations for more broadcast time. We propose a sign language broadcasting system for weather forecasts, and extend it for all kind of TV programs. In order to find the frequency of each word, we analysed the last three years' weather forecast scripts, and an opendomain corpus of about 1.2 million words from KBS. We use the Korean wordnet, KorLex, to build the sign language synonym dictionary, and for the word sense disambiguation to improve the translation performance. Optically-captured sign language motions are used for the 3D avatar to present sign language with motion blending. We developed a mobile ondemand sign language weather forecast application, and a real-time sign language interpretation system for all kind of TV programs.
