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.

This paper shows the design, implementation and evaluation of an algorithm that allows the extraction of Transport Stream's (TS) data section for Digital Terrestrial Television (DTT), with the organization in a hierarchical file system and directories based on MPEG-2 standard ISO-13818-6: Extension for Digital Storage Media Command and Control (DSM-CC), in order to fully recover the media from interactive applications contained by the MPEG-2 TS stream. To check the validity of the algorithm, it was implemented in a software to evaluate the application extraction of different TS, verifying its correct operation, as it successfully recovered all directories and files from interactive applications.

Since the year 2007, Escuela Politécnica del Ejército has been carrying out lab and field tests to evaluate the performance of current digital television systems. ISDB-Tb is the Japanese with Brazilian modifications digital terrestrial television standard adopted by Ecuadorian Government, which is able to transmit multiple television programs with interactive applications and high definition contents. This paper details tests about generation, transmission and reception of data flow TS containing multimedia, audio, video and interactive applications, using free distribution tools. This paper tries to be a reference document for those who want to start experimenting quickly, easily and cheaply, with interactive multimedia TS generation.
