Abstract
Methods, systems, and computer-readable media for output-aligned avail blanking for video streams are disclosed. Frame-rate conversion is performed on a video input. The video input is associated with a starting point in time for a break such as an avail break, and the video input has an input frame rate. The frame-rate conversion generates one or more video outputs whose frame rates may differ from the input frame rate. Blanking is performed on the video outputs after the frame-rate conversion. The blanking comprises modifying or inserting a sequence of frames, and a beginning of the sequence of frames is aligned with an indication of a start of the break. For multiple video outputs, a starting frame for the break is selected from the output having the lowest frame rate so that the start of the break is synchronized across the video outputs.
