摘要： It is provided a method for a computerized, server autonomously producing a TV show of a sports game in a scene. The method includes receiving from several video cameras a stream of video images of the scene for capturing a panoramic view of the scene, analyzing the stream of video images for allowing definition of several frame streams, determining location data of the frame streams accordingly, and rendering an active frame stream with images imaging a respective portion of the panoramic view of the scene. The method includes also transmitting for broadcasting a stream of image frames imaging the respective portion of the panoramic view. The step of analyzing the stream of video images includes identifying a playing object, tracking the playing, object and identifying players. The method also includes calibrating the cameras using points in the playing field. The method may include analyzing the stream of video images for identifying an event in the scene for switching between the active frame stream and a different frame stream. Also, the method may include directing a directed sensor to a region of interest in accordance with location data of the active, frame stream.

摘要： It is provided a method for producing a stream of desired image frames derived from a panoramic capturing of a scene by an array of video cameras. The production is conducted by a coordinated operation at a venue proximate to the scene and at a production suite located remotely from the venue. The method includes a venue server recording a stream of raw video images captured simultaneously by the video- cameras, and converting the stream of raw video images at a first data rate to a stream of panoramic views at a second data rate. The second data rate is less than one third of the first data rate. The method further includes transmitting the stream of panoramic views to a remote production suite, and there selecting a stream of desired frames including respective regions of interest. The method further includes transmitting data on the stream of desired frames to the venue server, and the venue server producing out of the recorded stream of raw video images, a stream of high resolution frames. The high resolution frames are characterized by non perceptible boundaries between neighboring images derived from respective neighboring raw video images.
