Abstract
Methods and systems for detecting block based video dropouts in one or more fields associated with various video frames is provided. A current field is divided into a plurality of blocks. A set of activity blocks is identified from the plurality of blocks. The activity blocks are then processed to identify horizontal and vertical lines which are then further processed to form one or more candidate error blocks. The candidate error blocks are validated for start and end to determine a count of video dropout errors associated with the current field.
