Preventing Packet Loss in Aggregated Streaming Data
نویسنده
چکیده
Introducing the problem of managing a buffer of bounded space, where arriving packets have dependencies among them. Multimedia applications require transmission of streaming video from a server to a client across an internetwork. In many cases loss may be unavoidable due to congestion or heterogeneous nature of the network. In this paper considered online policies for selective frame discard and analyse their performance by means of competitive analysis. Our online algorithm used to prove the upper bound is non pre-emptive no packet admitted to the buffer. Algorithm is, in case of an overflow, to prefer keeping packets from frames for which it has already delivered many packets, and dropping packets from frames with fewer packets already delivered. This algorithm essentially tries on effort already invested in delivering earlier packets of a frame.

A 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...

Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...

Packet loss recovery is an important part of P2P video streaming networks due to inevitable packet loss in today’s internet and interdependency of data units in compressed video streams. In addition, the architecture of P2P streaming networks, in which the data delivered to the receivers through chain of peers, can intensify the impact of the internet packet loss on the quality of perceived vid...
متن کاملStreaming MPEG-4 Video over Differentiated Services Networks
We investigate streaming MPEG-4 video over relative Differentiated Services (DS) networks that can provide Q aggregated classes ordered in a way such that class q is better or at least no worse than class (q-1) for 1 q Q < ≤ , in terms of packet loss. We propose an algorithm to measure the loss impact of a video packet on the quality of the decoded video images. We show how the optimal Quality ...
