Abstract: A system is provided for capturing a key signal within video frames that includes a camera that captures a sequence of media content of a live scene that includes an electronic display having a higher frame rate than an output frame rate of the camera, and a key signal processor that convert all frames in the sequence of media content to the output frame rate of the camera, analyzes a sequence of frames to determine the key signal based on the electronic display outputting a sequence of frames including media content and at least one key frame included in the sequence, and combine remaining frames of the sequence of frames to create a live output signal. Moreover, the key signal processor determines, for each pixel in the frames, whether the pixel has a set chromaticity, and generates a key mask for each pixel in each frame.

Abstract: A video signal combining apparatus comprises a video signal processing unit which is adapted to combine an output video image stream from two input image streams from first and second sources by dividing an image area of an image of said output video image stream into two regions and applying to said first region image information from said first source and applying to said second region image information from said second source, and a display unit for displaying at least one of said input and output video image streams, characterized in that the display unit is adapted to display a border between said first and second regions superimposed upon an image from one of said sources.

Abstract: A system is suggested that allows for transmitting a signal from at least one first camera to a second camera, upon activation by the camera operator of the respective first camera. The signal is displayed in the viewfinder of the second camera. The signal may include an indication that the operator of the at least one first camera has a ‘good-shot’, i.e. is currently capturing images that are ready for broadcasting and/or recording. In one embodiment the signal includes an identification of the camera that transmits the signal. In another embodiment the signal includes the video signal captured from the transmitting camera. In yet another embodiment the second camera displays images coming from multiple first cameras.
