We propose a novel data embedding scheme for fractional-pixel based video coding
algorithms such as H. 263 and MPEG-2. By modifying the motion estimation procedure at …

Lossy video compression algorithms, such as those used in the H. 261 and MPEG
standards, result in quality degradation seen in the form of tiling, edge business, and …

BACKGROUND In the existing block based video coding methods, there are basically two
types of coding modes: Intra mode and Inter mode. Intra mode only uses the information …

In real-time video streaming applications based on battery-powered camera systems, it is
crucial to capture and transmit critical information satisfying the storage capacity and …

This invention relates to compression of video image data for transmission over congested
internet networks, espe cially those networks having low data rates. 2. Description of the …

Reliable transmission of compressed video in a packet lossy environment cannot be
achieved without error recovery mechanisms. We describe an effective method for …

In digital broadcasting services such as digital satellite TV, cable TV, and digital terrestrial
TV, several video programs are compressed by MPEG-2 and then simultaneously …

Increasing the image size of a video sequence aggravates the memory bandwidth problem
of a video coding system. Despite many embedded compression (EC) algorithms proposed …

We show the performance of the proposed error resilient video coding system, which
dynamically replaces reference pictures in inter-frame coding according to the …

We propose a novel data embedding scheme for H. 263 video coding. The proposed
method, which can protect important information such as picture header and motion vector …
