This paper gives the overview of audio and video watermarking. This paper introduces the basic requirements that affect the algorithms for audio and video watermarking which are perceptibility, robustness and security. The attacks which cause manipulations of the audio and video signals are also discussed. The common group of attacks on audio and video data is dynamics, filtering, conversion, c...

According to reports about 30-thousand people spent watching television had the impact on their memory and recall that the results showed no differences between men and women. The people who watched less than an hour a day did better at every memory function. As these contributors watched negative political ads, physiological responses indicated that their body was reflexively preparing to move...

Abstract   The streamed audio video (AV) content for IPTV across mobile WiMAX channel, the different schemes were discussed to reduce the noise, packet loss and latency. The objective of this paper is to verify the effectiveness of forward error correction (FEC) techniques and to suggest the techniques for robustness problems and to analysis the issues either due to AV coding encoding or due to...

In order to protect the digital audio and video products copyright in the network, an improved audio blind watermarking algorithm scheme based on discrete wavelet transform (DWT) and singular value decomposition (SVD) is proposed. In the algorithm, an original audio is split as blocks and each block is decomposed on discrete wavelet transform for two degree, then first quarter audio approximate...

Viterbi Decoders (VDs) are today widely used as forward error correction (FEC) devices in many digital communications and multimedia products, including mobile (cellular) phones, video and audio broadcasting receivers, and modems. VDs are implementations of the Viterbi Algorithm (VA) used for decoding convolutional or trellis codes. The continuing success of convolutional and trellis codes for ...

Asynchrony between the audio and video track in streaming video can cause user frustration with the service but often goes unreported. Providers of on-demand internet streaming media such as Netflix reach millions of users and thus are concerned with supplying correctly aligned audio/video content. Our project will attempt to detect A/V misalignment in standard (nonstreaming) movie clips. We ex...

This paper investigates digital data hiding schemes. The concept of information hiding will be explained at first, and its traits, requirements, and applications will be described subsequently. In order to design a digital data hiding system, one should first become familiar with the concepts and criteria of information hiding. Having knowledge about the host signal, which may be audio, image, ...
