In this paper, we concentrate on data allocation methods for multiple wireless broadcast channels to reduce the average data access time. Existing works first sorted data by their access probabilities and allocate the partitions of the sorted data to the multiple wireless channels. They employ the Flat broadcast schedule for each channel to cyclically broadcast all the data items allocated to i...

In this paper, we derive information-theoretic performance limits for three classes of two-user statedependent discrete memoryless broadcast channels, with noncausal side-information at the encoder. The first class of channels comprises a sender broadcasting two independent messages to two non-cooperating receivers; for channels of the second class, each receiver is given the message it need no...

Broadcast and broadband communications have undoubt- edly become a part of today’s social life. Accessibility of content of interest to the audience at any place and at any time regardless of the type of content consumer device can have an effective contribution to the desire of the audience to use of the broadcast content. The HD and Ultra HD qualities, the desire for demand-driven application...

In this paper, we study power conservation techniques for multi-attribute queries on wireless data broadcast channels. Indexing data on broadcast channels can improve client filtering capability, while clustering and scheduling can reduce both access time and tune-in time. Thus, indexing techniques should be coupled with clustering and scheduling methods to reduce the battery power consumption ...

This paper investigates the problem of communicating video over a broadcast channel. The broadcast channel is expressed in terms of the channel capacity that exists between the transmitter and each receiver in the broadcast area { Shannon's separation theorem does not apply for video communication over this class of channels. Digital (discrete time, discrete amplitude) and hybrid (discrete time...

The aim of the paper is to present an analysis of implications of Internet on broadcast TV. The fundamental question addressed in academic and political discussions is whether Internet TV will substitute for or merely be a complementary platform to traditional broadcast services. On basis of technology-, marketand media-based and policy arguments, it is substantiated that the latter point is mo...

We propose a new coding technique based on nested coset codes and derive a new achievable rate region for a general three user discrete memoryless broadcast channel (DMBC). We identify an example of a three user binary broadcast channel for which the proposed achievable rate region strictly outperforms that obtained by a natural extension of Marton’s [1] rate region. As a step towards deriving ...
