Analysis of MPEG-2 Video Streams
"... MPEG-2 is widely used as video coding standard for contents such as DVD or digital video broadcasting, DVB. It defines a layered structure, composing three different types of frames into groups for temporal and spatial compression of video information. ..."

Lossless authentication of MPEG-2 video
- IEEE ICIP
, 2002
"... In authentication using watermarking, the original media needs to be slightly modified in order to embed a short media digest in the media itself. Lossless authentication watermark achieves the same goal with the advantage that the distortion can be erased if media authenticity is positively verifie ..."

verified. In this paper, we extend lossless data embedding methods originally developed for the JPEG image format to digital video in the MPEG-2 format. Two new lossless watermarking methods for authentication of digital videos are presented. In the first approach, each frame contains its hash embedded
WATERMARKING OF MPEG2 VIDEO STREAMS
, 2005
"... The main field of this study is digital watermarking of compressed video sequences. The targeted area in the field of digital watermarking is data embedding and indexing, which can be used in applications such as video indexing and retrieval. Having in mind that the content in video databases is mai ..."

is spread by a large chip factor, modulated by a pseudo sequence and then added to the DCT coefficients of an MPEG2 sequence. Detection probability was increased by a new block-wise random watermark bits interleaving. The watermark must be embedded in such a way that it does not introduce visual artefacts
Issues in H.264/MPEG-2 video transcoding
- Computer Science and Engineering
, 2004
"... The H.264 video coding standard has recently been standardized under the auspice of both the ITU and the ISO video experts groups. This new generation video standard, with its significant bandwidth savings, is expected to replace the use of MPEG-2 video compression in digital video systems. The comp ..."

Compressed Domain Mpeg-2 Video Editing
"... We propose an algorithm using picture type conversion to treat all the possible cases in compressed domain frame accurate MPEG2 video editing. The algorithm is based on a general open GOP. Conversion procedures are developed for each case. Experimental results show the algorithm is applicable to typ ..."

Adaptive MPEG-2 Video Data Hiding Scheme
"... We have investigated adaptive mechanisms for high-volume transform-domain data hiding in MPEG-2 video which can be tuned to sustain varying levels of compression attacks. The data is hidden in the uncompressed domain by scalar quantization index modulation (QIM) on a selected set of low-frequency di ..."

Burst-Packet-Loss Concealment for MPEG-2 Video
"... Abstract- In this paper, we propose an object-based error-concealment technique for MPEG-2 video transmitted in a burst-packet-loss environment. A burst packet loss typically impairs consecutive slices for the reconstructed picture. The proposed object-based error concealment proceeds in two stages, ..."
