We derive the capacity region for a broadcast channel with intersymbol interference (ISI) and colored Gaussian noise under an input power constraint. The region is obtained by first defining a similar channel model, the circular broadcast channel, which can be decomposed into a set of parallel degraded broadcast channels. The capacity region for parallel degraded broadcast channels is known. We...

This paper presents the architecture and implementation of a multi-service streaming system for broadcast of MPEG4 elementary streams. The proposed system promotes the use of the push channel model for information distribution [1]. The system architecture accommodates two main layers for broadcast service management and media delivery. The broadcast service management layer uses the publisher-s...

In this paper, we propose a new token-based distributed algorithm for total order atomic broadcast. We have shown that the proposed algorithm requires lesser number of messages compared to the algorithm where broadcast servers use unicasting to send messages to other broadcast servers. The traditional method of broadcasting requires 3(N − 1) messages to broadcast an application message, where N...

Rangelands are the main source of forage production whose degradation is being accelerated due to improper utilities. Furthermore, re-vegetation of palatable plants like Vicia variabilis is more limited in overgrazed rangelands. The objective of this study was to improve degraded rangelands in Meleh-Kabud (Kermanshah, Iran) through planting Vicia variabilis. The research was conducted at experi...

the purpose of this research was to aesthetically investigate and to analyze live multi-camera television broadcast of soccer matches. the research method was qualitative with in-depth and semi-open interviews. the statistical population consisted of 15 national and international sport producers and directors out of which 10 subjects were purposively selected as the sample of the study. this st...
