Abstract

Un televidente puede seleccionar entre una seleccion de ángulos de cámara y alimentaciones de audio disponibles cuando observa un evento deportivo, por ejemplo un juego de futbol, sin cambiar de canal de television. Los datos de audio, vídeo y control se transmiten en corrientes de datos en paquete con datos de control que proporcionan una designacion de canal preasignada (por ejemplo canal 10 para la red X). La terminal del aparato recibe y procesa las corrientes de datos de acuerdo a las ordenes proporcionadas por el usuario. La terminal incluye software que puede descargarse mediante las corrientes de datos o instalarse localmente. Los datos de control en la corriente de datos se utilizan para proporcionar una exhibicion gráfica en pantalla sobre la television, que permite que el usuario seleccione el audio y el video que corresponden a ciertas áreas del estadio de futbol, por ejemplo. Opcionalmente, el televidente puede seleccionar líneas de historia alternativas en una película o programa similar. Un ajuste por emision proporciona señales de audio y video primarias. Las señales de audio y video alternativa se seleccionan por el usuario y se mapean hacia el designador de canal de la señal primaria de manera que puedan observarse y escucharse ángulos de cámara y alimentaciones de audio diferentes. El televidente tiene por lo tanto la oportunidad de individualizar la programacion con objeto de mejorar su valor de entretenimiento o educativo.
