  • Publication number: 20150249847
    Abstract: A system and method for providing integrated advertising in a television distribution network is disclosed. The system comprises a storage module, a processor in communication with the storage module and a chroma-keying module. The storage module stores one television program and one image to be integrated with the television program. The processor divides a background of the television program into a plurality of frames. The processor identifies the background colour of each spatial frame. The chroma-keying module compares the background colour of each frame with a pre-selected chroma range for integrating the image into detected frame, when the background colour of the frame matches with one key-colour in the pre-selected chroma range. The spatial frame is replaced with a preset advertisement based on the type, genre and time of the telecast program on a plurality of channels.
