Resolucion Rectoral 87/03 que dispone el uso de la GPL para radioU.

Descripcion

RadioU es una aplicacion libre, licenciada bajo la GPL, que opera una radio: arma la programacion por dias y por programas, reproduce esta programacion, registra el aire emitido, esto ultimo para los entes reguladores de radiodifusoras.

La emision del aire de la radio se maneja reproduciendo archivos de sonido en formato MP3, almacenados en un disco duro, estos archivos en formato MP3 comprenden todo el material sonoro de una emisora, musica, tandas institucionales y comerciales, archivos de sonido de Hora y Minuto.

El armado de la musicalizacion de cada programa y de la programacion diaria, se hace atraves del manejo de una Base de Datos. Esta Base de Datos se genera de una manera practica, leyendo el encabezado de los archivos en Formato MP3.

Tiene Interfaz gráfica intuitiva y amigable, haciéndolo práctico y fácil de usar.

Puede ser instalado en varias maquinas conectadas en red y la interacción se realiza a través del servidor de la Base de Datos (MySQL).

Es posible definir distintos perfiles de usuarios y asignarles permisos restringiendo su acción.

El sistema puede potencialmente administrar tambien video.

Análisis de la Radio

Se analizaron las tareas de la radio y se concluyó que no existe software GNU Linux disponible que cumpla con sus requerimientos. Por esa razón se determinó que era necesario un software especifico que permita la automatización de las siguientes funciones:

    Objectives

    To automate on-the-air production (musical programming and advertising), technical operation and broadcasting of a radio station.

    Details as follows:

    Modules:

    Musical Programming: It involves setting up the musical programming of the radio shows. The musical programming of every show is a list of songs to be broadcast at a certain date and time. Songs may be either in digital format (sound files) or otherwise (CDs, LPs, casettes, etc.). In both cases, the software can store information on the songs (title, author, singer, album, genre, etc.) which will later be used in arranging the lists of musical programming.

    As regards sound files in MP3 Format, the songs database can be updated automatically by reading the information in the song headings. The Administration forms allow the clasifying, ordering and fittering of the songs by means of both the information on their albums and the songs themselves, so as to make the creation of the reproduction lists easier. Once the songs are selected from the Administration Forms, they are easily included in the musical programming by using the mouse or the keyboard.

    As for music not in digital form, the software is capable of storing all information necessary to locate it easily when needed, apart from arranging the reproduction lists, which includes the exact or approximate lenght of every song for greater time management.

    It is also possible to arrange musical schemes, such as background,opening and wrap-up music, as well as sound effects (lughing, clapping, etc.) that make up the esthetics proper to the station.

    The software makes it possible to keep a record of the music used in the shows, which provides greater control of music variety used by the radio station. Advertising Sequences: By sequence is meant a series of adverts broadcast at regular time intervals programmed by the software.

    The software makes possible for managing the information of ads, which are, in turn, sound files with features of their own: they refer to a certain client, are meant to be on the air for a certain period, on such-and-such time schedule, under such conditions and price, etc. This information is used by the software to assist the user in arranging the advertising sequences.

    The software is also capable of reading the time and weather conditions with every sequence.

    Technical Operation and Broadcasting: Broadcasting refers to the reproduction of the songs that constitue the music of the radio shows to be aired and the advertising sequences arranged for the selected date. The software can be operated either automatically or manually. When used manually, the software provides the operator with all the tools needed to carry out his work: managing and broadcasting (reproduciong, pausing, stopping, fast-forward, rewinding, controlling the volume,etc.) and modifying it as necessary (adding, substracting, rearranging, etc.), checking that all these actions are registered in the reproduction list and its timing. The Automatic Operation is meant to be used when the operator does not take part in the broadcasting, for example, on holidays. In such cases, the software automatically broadcasts the previously arranged reproduction list, respecting the advertising sequences over songs.

    Any broadcasting of a sound file is recorded in a text file, in which date, time, beginning and end of every emision is registered. This record is used to send reports to various regulating authorities.

    Main Features

    Graphic Interface: The graphic interface of the software was designed under principles of the standard interface, which makes it both intuitive and user-friendly. Due to its well-designed interface, learning to use the software is easy and the shift from other systems (namely windows) is not that traumatic. Network work: The software can be installed in several computers linked in network and can be configured to acces the database in a server. In this way, the interaction between the terminal is carried out by means of database server.

    Multiple User Profiles: It is possible to define different user profiles so as to provide them with a certain level of acces or action. For example to restrict the operator's movement to changing the sequence only, or to prevent the user arranging the musical programming frommodifying the bradcasting, etc. Practice and Intuitive: Forms were designed to enable the user attain the best results in few steps, and simultaneously, to be in control of the appliance. Such is the case of the Administration Forms, which make the searching easier by means of ordering and fitterin tools. In addition, the similarity in appearance and function with Window programms.

    Robustness: the software4 was tested exhaustively in order to improve the performance of the appliance. The software code includes good routines in error handling, which translates into greater robustness for the apliance, and so, into greater quality.
