Summary:Techniques are disclosed to add augmented reality to a sub-view of a high resolution central video feed. In various embodiments, a central video feed is received from a first camera on a first recurring basis and time-stamped position information is received from a tracking system on a second recurring basis. The central video feed is calibrated against a spatial region encompassed by the central video feed. The received time-stamped position information and a determined plurality of tiles associated with at least one frame of the central video feed are used to define a first sub-view of the central video feed. The first sub- view and a homography defining placement of augmented reality elements on the at least one frame of the central video feed are provided as output to a device configured to use the first sub-view and the homography display the first sub-view. Se revelan técnicas para agregar realidad aumentada a una vista secundaria de una transmisión de video central de alta resolución. En varias realizaciones, se recibe una señal de vídeo central de una primera cámara en una primera base recurrente y la información de posición con marca de tiempo se recibe de un sistema de seguimiento en una segunda base recurrente. La fuente de vídeo central se calibra con respecto a una región espacial abarcada por la fuente de vídeo central. La información de posición con marca de tiempo recibida y una pluralidad determinada de mosaicos asociados con al menos un fotograma de la fuente de vídeo central se utilizan para definir una primera subvista de la fuente de vídeo central. La primera subvista y una homografía que define la ubicación de los elementos de realidad aumentada en al menos un fotograma de la fuente de vídeo central se proporcionan como salida a un dispositivo configurado para utilizar la primera subvista y la pantalla de homografía la primera subvista.
