Teleradiology, sending of x-rays, is the most common application of telemedicine in use today. Mobile telemedicine is the latest area of research where the patient can be monitored remotely by a doctor. In this paper, we propose a teleradiology system whereby the communication is
Coding schemes for time encoded speech (TES) voice messages
This paper reports an an investigation into the use of Time-Encoded Speech (TES) [1] for the economical storage of digital voice messages in the tactical military arena. Initial results indicate that bit rate· reductions of between 20°/o and 55°/o may be available using simple co
Performance Studies of a Coding Scheme for a Slepian-Wolf Source Network
We investigate the simplest Slepian-Wolf source network, consisting of an information source correlated with a second source used as a side-information for the decoder but not the encoder. The information source and side-information source are modeled as binary random sequences }
Coding Schemes for the Two-Way Relay Channels
In modern transmission networks, relay plays an important role for cooperative strategies. Several relaying strategies, such as decode-forward, compress-forward and amplify-forward, have been proposed for relay channels and networks. However, the capacity for the general relay ch
Efficient bit-plane coding scheme for fine granular scalable video coding
In this paper, we propose a new efficient bit-plane coding method for fine granular scalable (FGS) video coding. The general structure of the proposed bit-plane coding method is based on the traditional bit-plane coding scheme in MPEG-4 FGS. However, to enhance coding efficiency
A Lossless Multichannel Bio-Signal Compression Based on Low-Complexity Joint Coding Scheme for Portable Medical Devices
Research on real-time health systems have received great attention during recent years and the needs of high-quality personal multichannel medical signal compression for personal medical product applications are increasing. The international MPEG-4 audio lossless coding (ALS) sta
A new universal coding scheme for the binary memoryless source
A coding scheme for the binary memoryless source is presented. The scheme is an extension of a scheme discovered by Lynch and Davisson and developed by Schalkwijk, and is based upon the Schalkwijk algorithm for the Lynch-Davisson (LD) code. The new coding scheme is shown to be as
A data embedded video coding scheme for error-prone channels
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 fractional-pel precision, two bits data can be embedded in a motion vector (MV) for a inter-mode coded macroblock
A batched network coding scheme for wireless networks
Several wireless network coding schemes apply either inter-flow traffic or intra-flow traffic, but not both. This paper proposes a novel batched network coding scheme to deal with both inter-flow and intra-flow traffics, which attempts to combine the advantages of both network co
New coding schemes for the symmetric K -description problem
We propose novel coding schemes for the Kdescription problem with symmetric rates and symmetric distortion constraints. There are two main new ingredients in these schemes: the first one is akin to the method seen in the well-known butterfly network of network coding literature,
