This paper proposes the use of repetitive broadcast as a way of augmenting the memory hierarchy of clients in an asymmetric communication environment. We describe a new technique called “Broadcast Disks” for structuring the broadcast in a way that provides improved performance for non

between clients and servers. In previous papers, we have proposed Broadcast Disks as a model for structuring the repetitive transmission of data in a broadcast medium. Broadcast Disks are intended for use in environments where, for either physical or application-dependent reasons, there is asymmetry

In the problem of minimum-energy broadcasting in a wireless network, the objective is to broadcast data reliably to all network nodes at a fixed rate with minimum transmitted power. In [3], this problem was formulated as a minimum-cost broadcast tree problem and the well-known heuristic

In order to address the scalability problems of Video– on–Demand systems, several periodic broadcast schemes have been proposed that partition a video into segments and repetitively broadcast each segment on a separate channel. A new scheme is presented for the bandwidth–efficient periodic

Broadcasting quotas of domestic contents are commonplace in developed countries. The core argument for them is to promote diversity by making more room for domestic content and hence foster a more diverse production. However, this intuitive reasoning ignores the trade-off between repetition

diverse production. However, this intuitive reasoning ignores the trade-off between repetition (broadcasting more of the same) and new program diffusion that the broadcaster faces. If each consumer cares only about a small fraction on the total contents of the program, and that some con-tents are more

This paper addresses the problem of automatic TV broad-casted program extraction. It consists firstly of precisely de-termining the start and the end of each broadcasted TV pro-gram, and then of properly giving them a name. The extracted programs can be used to build novel services like TV

Abstract — In this paper, we propose a method for detecting and precisely segmenting repeated sections of broadcast streams. This method allows advertisements to be removed and replaced with new ads in redistributed television material. The detection stage starts from acoustic matches and validates

Abstract—Broadcast communications is critically important in vehicular networks. Many safety applications need safety warning messages to be broadcast to all vehicles present in an area. In this article, we propose a novel repetition-based broadcast protocol based on “optical orthogonal codes

Abstract. This paper investigates the practical security of RC4 in broadcast setting where the same plaintext is encrypted with different user keys. We introduce several new biases in the initial (1st to 257th) bytes of the RC4 keystream, which are substantially stronger than known biases
