TLDR
An empirical study to investigate the effectiveness of hierarchical coding through the hierarchical mode of JPEG from a network perspective and shares the experiences in the implementation of hierarchical JPEG.Abstract:
Hierarchical coding of images and continuous media can be used to effectively control congestion in high-speed networks supporting interactive multimedia communications. However, the tradeoffs of the use of hierarchical coding have not yet been adequately investigated. We have undertaken an empirical study to investigate the effectiveness of hierarchical coding through the hierarchical mode of JPEG from a network perspective. A static analysis of hierarchical JPEG images in comparison to baseline JPEG images in terms of QoS management by packet discarding is provided. We also share our experiences in the implementation of hierarchical JPEG.read more

Apparatus for transmitting/receiving wireless data and method thereof
Jeong-Hoon Park,Dong-Seek Park +1 more
TL;DR: In this paper, a method for transmitting and/or receiving wireless data and an apparatus therefor is provided, which includes the steps of determining whether or not a loss of data occurred, by referring to the information on the length and location of data divided into the protocol units in the step (a), and inserting blank data into the part corresponding to the lost data to re-form the entire collection of data.

Multi-resolution Layered Coding for Real-Time Image Transmission
James Han,George C. Polyzos +1 more
TL;DR: It is demonstrated that MLC exhibits good error tolerance, effectively compensating for errors in situations where traditional error concealment schemes are ineffective, and yields a higher peak signal-to-noise ratio than two-layer coding when packet loss occurs in the base layer.

Multicast routing for multimedia communication
TL;DR: The authors present heuristics for multicast tree construction for communication that depends on: bounded end-to-end delay along the paths from source to each destination and minimum cost of the multicasts, where edge cost and edge delay can be independent metrics.

Two-layer coding of video signals for VBR networks
TL;DR: Two-layer conditional-replenishment coding of video signals over a variable-bit-rate (VBR) network is described and it is shown that the coder performs well for a guaranteed channel rate as low as 10-20% of the total bit rate.

Multipoint communication by hierarchically encoded data
TL;DR: The author gives an overview of several hierarchical signal coding techniques; presents methods for finding maximum bandwidth available to destination, establishing maximum-bandwidth routes; and optimally assigns bandwidth to the signal layers to maximize overall reception quality.
