Resumen
A partir del año 2013 en nuestro país se ha venido desplegando la TDT. En dicho despliegue se ha utilizado la norma china GB 20600-2006 o DTMB y hasta el momento solo se le ha incluido un nivel de interactividad muy limitado para la transmisión de información.
La interactividad es la capacidad de ofrecer servicios adicionales a los programas de televisión, permitiendo al espectador ver informaciones adicionales asociadas al contenido principal e interactuar con la propia televisión. Para poder trabajar este tema es necesario que el país cuente con una norma en la que se especifiquen y regule todos los aspectos funcionales, tecnológicos y legales que regulen la forma en que se usa y desarrollan las aplicaciones interactivas.
En el presente trabajo se proponen varias directivas que se deben tener en cuenta a la hora de desarrollar el estándar para Cuba. Varias de ellas dirigidas a que el desarrollo de este y su vida no fracasen; buscando adaptabilidad y facilitando el acceso a contenidos no relacionados a la transmisión. La integridad de los contenidos presentados es abordada así como la accesibilidad, la preservación del entorno de visualización o la protección de los datos del usuario.
En cuanto a las tecnologías y diseño del futuro estándar se hace referencia a varios lenguajes actualmente usados en la implementación de sistemas interactivos como es CE-HTML. Se hace énfasis en el uso imperativo de tecnologías estandarizadas, así como se establecen las características mínimas que deben cumplir los medios receptores de las señales y la capacidad de combinación de estas por los mismos. Se debe tener en cuenta la protección contra la piratería y la aplicabilidad de todas estas características a los contenidos de la radio.
También se relacionan las propuestas de la arquitectura de los sistemas de interactividad, la arquitectura básica de los terminales receptores y los elementos que no deben faltar en la estructura del documento del estándar.
Since 2013 in our country has been deploying Digital Terrestrial Television (DTT). In this deployment, the Chinese standard GB 20600-2006 or DTMB has been used with a very limited level of interactivity included for the transmission of information. Interactivity is the ability to offer additional services to television programs, allowing the viewer to see additional information associated with the main content. In order to work on this issue, it is necessary for the country to have a standard that specifies and regulates all the functional, technological and legal aspects that regulate the way in which interactive applications are used and developed. In the present work several directives are proposed that must be taken into account when developing the standard for Cuba. Several of them aimed at the development of this and his life do not fail; looking for adaptability and facilitating access to content not related to transmission. The integrity of the presented contents is approached as well as the accessibility, the preservation of the visualization environment or the protection of the user's data. As for the technologies and design of the future standard, reference is made to several languages currently used in the implementation of interactive systems such as CE-HTML. Emphasis is placed on the imperative use of standardized technologies, as well as establishing the minimum characteristics that must be met by the means receiving the signals and the ability to combine them. The protection against piracy and the applicability of all these characteristics to the contents of the radio should be taken into account. The proposals for the architecture of the interactivity systems, the basic architecture of the receiver terminals and the elements that must be present in the structure of the standard document are also related.
