Distributed Video Coding Using LDPC Codes for Wireless Video
Popular video coding standards like H.264 and MPEG working on the principle of motion-compensated predictive coding demand much of the computational resources at the encoder increasing its complexity. Such bulky encoders are not suitable for applications like wireless low power surveillance, multimedia sensor networks, wireless PC cameras, mobile camera phones etc. New video coding scheme based...
متن کاملMulti-Hypothesis based Distributed Video Coding using LDPC Codes
Conventional video coding paradigms are usually built on the assumption that a video stream will be encoded only once but decoded several times. Over the years, this has lead to the development of encoders, which use complex motion-estimation algorithms to reduce the size of the video bitstream. However in applications like distributed sensor networks, cell-phones etc. the encoder has a limited...
متن کاملNew Counting Codes for Distributed Video Coding
This paper introduces a new counting code. Its design was motivated by distributed video coding where, for decoding, error correction methods are applied to improve predictions. Those error corrections sometimes fail which results in decoded values worse than the initial prediction. Our code exploits the fact that bit errors are relatively unlikely events: more than a few bit errors in a decode...
متن کاملOn the Comparison of Distributed Video Coding Using Ldpc Codes on Bit Plane and Symbol Level
Many distributed video coders are implemented using sophisticated error correction codes that use soft information ( conditional probabilities) as a priori knowledge. This a priori information models the dependency behavior between the input data and side-information. In this paper we analyze both a symbol and bit plane based approach using LDPC codes. We show that a bit planebased encoder has ...
متن کاملDistributed Video Coding with Background Modeling for Wireless Video Surveillance
Video compression takes a very important part in multimedia communication. New applications require constrained resources in terms of power, computational complexity, memory and robustness. Distributed video coding (DVC) provides a solution to achieve such constraints. However, DVC has a low coding efficiency, the overall performance is lower than the H.264/AVC [1] codec. In low-motion scenes s...
