Abstract :
With the development of broadcasting and digital TV, the security of broadcasting is becoming necessary. However, there has not been an effective solution now. This paper introduces a content monitoring system based on MPEG-2 video watermarking. By using our MPEG-2 bitstream video watermarking algorithm based on BCH error-correcting-code (ECC) and compensation techniques, the system can detect whether the digital video has been altered on the temporal axis and filter the illegal video automatically. Combined with the usage of DSP real-time processing and network technology, this system can be widely used in digital TV system and other broadcasting fields.
