Multiple Description Scalable Coding for Video Transmission over Unreliable Networks
Developing real time multimedia applications for best effort networks such as the Internet requires prohibitions against jitter delay and frame loss. This problem is further complicated in wireless networks as the rate of frame corruption or loss is higher in wireless networks while they generally have lower data rates compared to wired networks. On the other hand, variations of the bandwidth a...
متن کاملLayered Multiple Description Coding For Robust Video Transmission Over Wireless Ad-Hoc Networks
This paper presents a video transmission system using layered multiple description (coding (MDC) and multi-path transport for reliable video communications in wireless ad-hoc networks. The proposed MDC extends a quality-scalable H.264/AVC video coding algorithm to generate two independent descriptions. The two descriptions are transmitted over different paths to a receiver in order to alleviate...
متن کاملMultiple Description Scalable Coding for Error Resilient Video Transmission over Packet Networks
Two types of scalabilities exist in current scalable video streaming schemes: (1) nested scalability, in which different representations (i.e., descriptions) of each frame are generated using layered scalable coding and have to be decoded in a fixed sequential order, and (2) parallel scalability, which is used in multiple description coding (MDC) where different descriptions are mutually refina...
متن کاملMultiple description video coding through adaptive segmentation
Multiple description video coding is one method that can be used to reduce detrimental effects caused by transmission over lossy packet networks. In a multiple description system, a video sequence is segmented into two or more complimentary streams in such a way that each stream is independently decodable. When combined, the streams provide the highest level of quality, yet if one of the stream...
متن کاملA Method to Reduce Effects of Packet Loss in Video Streaming Using Multiple Description Coding
Multiple description (MD) coding has evolved as a promising technique for promoting error resiliency of multimedia system in real-time application programs over error-prone communicational channels. Although multiple description lattice vector quantization (MDCLVQ) is an efficient method for transmitting reliable data in the context of potential error channels, this method doesn’t consider disc...
