“…For example, it has been shown that time slicing enables mobile devices to turn off their RF circuits for a significant fraction of the time [13,14]. The works in [13,14] did not solve the burst transmission problem. Balaguer et al [15] proposed an energy saving strategy by not receiving more FEC bytes once the data can be successfully reconstructed.…”

Abstract. We study the problem of broadcasting multiple scalable video streams to heterogeneous mobile devices, which have limited energy budgets. We show that scalable video streams should be broadcast in a different manner than nonscalable streams; otherwise energy of mobile devices could be wasted. We propose an efficient broadcast scheme for mobile TV networks that explicitly supports heterogeneous mobile devices, and we show its correctness as well as performance in terms of energy saving. We implement the proposed scheme in a real mobile TV testbed to evaluate its performance. Our results indicate that, with the proposed broadcast scheme, significant energy savings can be achieved by different heterogeneous devices. For example, using the proposed broadcast scheme allows mobile devices to achieve energy saving between 62% to 92%, while using the current broadcast scheme only allows them to achieve energy saving 62% despite how many layers they can (or opt to) receive and decode.

Always user interaction has been one of the most crucial points when evaluating the quality of services. Mobile television is one of the most important services for the users. Problem of broadcast video streams encoded in scalable manner to enable heterogeneous mobile devices to render the most appropriate video sub-streams. Due to more than one layer channel switching delay and energy saving problem occur. For this purpose, we proposed a new video broadcast scheme for 3G mobile devices, where every layer has two parts for every TV channel, two part of every layer takes approximate half time to switch the next TV channel as compare to current broadcast scheme and reduce energy consumption. For the purpose of channel switching, we insert bootstrap in first part of every TV channel. Bootstrap is use to reduce the channel switching delay. Our extensive results confirm that the proposed schemes enable energy saving 0.0065 % observed and achieve less delay 129.0029 msec is possible with typical system parameters as compare to current broadcast scheme. General TermsThis paper is useful for the scalable video broadcasting to heterogeneous mobile devices. During the classification of this material comes into video broadcast in 3G mobile devices.

“…The γ s values indicate the energy saving due to time slicing, and it has been used by previous works in the literature [14], [15] and in the standardization documents [4]. We define the average system-wide energy saving over all TV channels as γ = S s=1 γ s /S.…”

Abstract-Mobile TV networks have received significant attention from the industry and academia, as they have already been deployed in several countries and their expected market potential is huge. In such networks, a base station broadcasts TV channels in bursts with bit rates much higher than the encoding bit rates of the videos. This enables mobile receivers to receive a burst of traffic and then turn off their receiving circuit till the next burst to conserve energy. The base station needs to construct a transmission schedule for all bursts of different TV channels. Constructing optimal (in terms of energy saving) transmission schedules has been shown to be an NP-complete problem when the TV channels are encoded at arbitrary bit rates. In this paper, we propose a near-optimal approximation algorithm to solve this problem. We prove the correctness of the proposed algorithm and derive its approximation factor. We also conduct extensive evaluation of our algorithm using real implementation in a mobile TV testbed and simulations. Our experimental and simulation results show that the proposed algorithm: (i) is practical and produces correct burst schedules, (ii) achieves near-optimal energy saving for mobile devices, and (iii) runs efficiently in real time.
