Abstract
This paper presents an efficient video compression and transmission scheme based on the Set Partitioning In Hierarchical Trees (SPIHT) algorithm and chaotic Baker map interleaving. The compressed video frames have self-embedded digital signatures, and the transmission is performed over Orthogonal Frequency Division Multiplexing wireless systems with equalization. The video frames compressed with SPIHT algorithm are primarily converted to the luminance and chrominance scheme for self-watermark embedding, and then the binary format is reconstructed again. Prior to the modulation step, the chaotic randomization is performed on the binary data to encrypt the data to be transmitted and reduce the noise impact of the multipath channel. For performance evaluation, both Rayleigh and additive noise channels are considered for various video frames with chaotic interleaving. The simulation results reveal that the received watermarked video frames with chaotic interleaving applied achieve higher Peak Signal-to-Noise Ratios and correlation coefficients compared to other approaches.
