چکیده
In this paper, we propose a video Watermarking technology to hide copyright information by a slight modification of the motion vector, in MPEG2 video bitstream. In this method, watermark is embedded in the motion residual of large value motion vector, then the motion residual are regularized into a modified bitstream, from which the watermark information can be retrieved easily and exactly. From the experimental results, this technology has the advantage of little influence on the MPEG decoding speed , little degrading the perceptive effect, capability to embed watermark in a short video sequence, and can be used to watermark directly on compressed and uncompressed video sequence. Keywords-watermark; MPEG; motion vector

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...

This paper presents an improved IP condition of network and the different importance of video differentiated services (DinServ) framework which is suitable streams for decoder over DiffServ networks. for real-time video transmission. Especially, we investigate MPEG-4 video transmission. Based on the feature of MPEG-4 flow and the extent of network congestion, implements a new DiffServ marking a...
متن کاملAn Mpeg-4 Bifs-based Authoring Tool for Multimedia Content
In this paper, we propose an authoring tool referred to as ICCT (Interactive Content Creating Tool). The tool serves to easily generate as well as dynamically control a multimedia and interactive MPEG-4 content represented as a hierarchical scene graph. In the parametric mode of ICCT, scene-designer – using a user friendly interface for setting properties of objects in the scene can create an e...
متن کاملA chaos-based video watermarking algorithm
The intriguing characteristics of chaotic maps have prompted researchers to use these sequences in watermarking systems to good effect. In this paper we aim to use a tent map to encrypt the binary logo to achieve a like-noise signal. This approach makes extraction of the watermark signal by potential attacker very hard. Embedding locations are selected based on certain principles. Experimental ...
متن کاملWatermarking low bit-rate Advanced Simple Profile MPEG-4 bitstreams
This paper presents a novel watermarking method for low bitrate video that is compressed according to the Advanced Simple Profile of MPEG-4. A spatial spread spectrum watermark was embedded directly to the MPEG-4 bit-streams by adopting Hartung’s approach of watermarking MPEG-2 compressed bitstreams. A synchronization template was employed to combat cropping, scaling, and rotation. A gain contr...
