    ABSTRACT: — Users of modern portable consumer devices (smartphones, tablets etc.) expect ubiquitous delivery of high quality services, which fully utilise the capabilities of their devices. Video streaming is one of the most widely used yet challenging services for operators to deliver with assured service levels. This challenge is more apparent in wireless networks where bandwidth constraints and packet loss are common. The lower bandwidth requirements of High Efficiency Video Coding (HEVC) provide the potential to enable service providers to deliver high quality video streams in low-bandwidth networks; however, packet loss may result in greater damage in perceived quality given the higher compression ratio. This work considers the delivery of HEVC encoded video streams in impaired network environments and quantifies the effects of network impairment on HEVC video streaming from the perspective of the end user. HEVC encoded streams were transmitted over a test network with both wired and wireless segments that had imperfect communication channels subject to packet loss. Two different error concealment methods were employed to mitigate packet loss and overcome reference decoder robustness issues. The perceptual quality of received video was subjectively assessed by a panel of viewers. Existing subjective studies of HEVC quality have not considered the implications of network impairments. Analysis of results has quantified the effects of packet loss in HEVC on perceptual quality and provided valuable insight into the relative importance of the main factors observed to influence user perception in HEVC streaming. The outputs from this study show the relative importance and relationship between those factors that affect human perception of quality in impaired HEVC encoded video streams. The subjective analysis is supported by comparison with commonly used objective quality measurement techniques. Outputs from this work may be used in the development of quality of experience (QoE) oriented streaming applications for HEVC in loss prone networks

    ABSTRACT: Disparity estimation is a common task in stereo vision and usually requires a high computational effort. High resolution disparity maps are necessary to provide a good image quality on autostereoscopic displays which deliver stereo content without the need for 3D glasses. In this paper, an FPGA architecture for a disparity estimation algorithm is proposed, that is capable of processing high-definition content in real-time. The resulting architecture is efficient in terms of power consumption and can be easily scaled to support higher resolutions.

    ABSTRACT: One of the main imperfections in orthogonal frequency division multiplexing (OFDM) techniques is a peak-to-average power ratio (PAPR) or crest factor (CF). High crest factor signal forces a power amplifier in communication systems to back-off which leads to power efficiency degradation. Several techniques have been proposed in literature to mitigate the high peaks in OFDM signal; however most of them suffer from complexity and PAPR performance. In conventional SLM (C-SLM), increasing the number of inverse fast Fourier transform (IFFT) leads to excessive hardware resources requirement and increases system cost. In this paper a novel crest factor scheme based on recursive optimum frequency domain matrix is proposed which requires only two IFFT which results in significant reduction in the computational complexity. Simulation results show both the complexity and crest factor are reduced significantly compared to the conventional methods.

    ABSTRACT: Various fall-detection solutions have been previously proposed to create a reliable surveillance system for elderly people with high requirements on accuracy, sensitivity and specificity. In this paper, an enhanced fall detection system is proposed for elderly person monitoring that is based on smart sensors worn on the body and operating through consumer home networks. With treble thresholds, accidental falls can be detected in the home healthcare environment. By utilizing information gathered from an accelerometer, cardiotachometer and smart sensors, the impacts of falls can be logged and distinguished from normal daily activities. The proposed system has been deployed in a prototype system as detailed in this paper. From a test group of 30 healthy participants, it was found that the proposed fall detection system can achieve a high detection accuracy of 97.5%, while the sensitivity and specificity are 96.8% and 98.1% respectively. Therefore, this system can reliably be developed and deployed into a consumer product for use as an elderly person monitoring device with high accuracy and a low false positive rate.

    ABSTRACT: For gain-shape split vector quantization, an incremental M (IM) search algorithm is proposed. In the conventional M search, every possible combination of subvectors is evaluated. However, in the proposed IM search, an intermediate subvector is constructed by merging adjacent subvectors in an incremental and recursive way. Based on the IM search, the high-dimensional Karhunen-Loeve Transform (KLT) based speech coder is designed in practice. IM search requires 1800 times lower complexity than M search in designing a high-dimensional KLT-CVQ. Based on the proposed KLT based speech coder, a novel voice over IP (VoIP) system is designed, which produces superior voice quality and rate-distortion performance to conventional VoIP systems.

    ABSTRACT: Unpredictable battery lifetime arising from multitasking can have a significant negative effect on availability for mobile devices. In practice, some applications are prioritized and required to remain in operation for certain duration. This paper suggests a battery lifetime guaranteeing scheme for prioritized applications in multitasking mobile systems. The proposed approach profiles and analyzes the battery usage pattern of each task dynamically, and preserves the energy budget for operation of prioritized tasks for a guaranteed time. In addition, this paper proposes an energyconstrained scheduler that limits the energy consumption of tasks while preserving scheduling patterns, which translates to the QoS. The suggested scheme is implemented in a commercial smartphone and evaluated. The evaluation showed that the proposed scheme successfully provides guaranteed operation time for prioritized tasks.

    ABSTRACT: In this paper, a vision based voice activity detection (VVAD) algorithm is proposed using chaos theory. In conventional VVAD algorithm, the movement measure of lip region is found by applying an optical flow algorithm to detect the visual speech frame using a motion based energy feature set. However, since motion based feature is unstable under illumination changes, a new form of robust feature set is desirable. It is propositioned that contextual changes such as lip opening or closing motion during speech utterances under illumination variation can be observed as chaos-like and the resultant complex fractal trajectories in phase space can be observed. The fractality is measured in phase space from two sequential video input frames and subsequently any visual speech frames are robustly detected. Representative experiments are performed in image sequence containing a driver scene undergoing illumination fluctuations in moving vehicle environment. Experimental results indicate that a substantial improvement is obtained in terms of achieving significantly lower false alarm rate over the conventional method.

    ABSTRACT: This paper presents a concept of optical image stabilization for miniature digital cameras using magnetic actuators. The proposed device has a 3 degrees-of-freedom flexible lens platform, which is actuated by four magnetic actuators. The device uses position feedback control to counter-rotate the lens to compensate for vibration disturbance introduced by the user's hand-shake. A dynamic model of the device is developed for the feedback controller design purpose. Controller design and simulations based on actual hand-shake data collected from the gyro sensors of a mobile device are presented. Experimental results of a single degree-of-freedom large-scale prototype demonstrate vibration compensation up to 45 Hz.

    ABSTRACT: The Universal Serial Bus (USB) is an extremely popular interface standard for computer peripheral connections and is widely used in consumer Mass Storage Devices (MSDs). While current consumer USB MSDs provide relatively high transmission speed and are convenient to carry, the use of USB MSDs has been prohibited in many commercial and everyday environments primarily due to security concerns. Security protocols have been previously proposed and a recent approach for the USB MSDs is to utilize multi-factor authentication. This paper proposes significant enhancements to the three-factor control protocol that now makes it secure under many types of attacks including the password guessing attack, the denial-of-service attack, and the replay attack. The proposed solution is presented with a rigorous security analysis and practical computational cost analysis to demonstrate the usefulness of this new security protocol for consumer USB MSDs.

    ABSTRACT: This paper presents an automated power model generation method for smartphones. Having an accurate power model of mobile devices can help identify the sources of fast discharge of the battery and provide opportunities for optimizing battery use. However, current methods rely on either external measurement equipment or internal current sensor support. This study presents a novel method for power modeling that exploits the usage patterns stored on the phone. This method can be applied to any mobile device regardless of the manufacturer and the model of the device. A power consumption analysis tool, and an artificial usage pattern generator tool have been developed for power modeling. The proposed method is able to generate an accurate power model of various smartphones even without detailed knowledge of the phone hardware.

    ABSTRACT: As energy consumption in residential areas is rising, residential homes have deployed a photovoltaic (PV) system to save energy cost. The PV system needs to be continuously monitored to maintain its appropriate performance. In addition, it is desirable to monitor each PV module because one abnormal PV module affects the whole PV system. In this paper, the power line communication (PLC) compliant with HomePlug is adopted to monitor each PV module. The system architecture is composed of three components: PLC modem, renewable energy gateway (REG), and smart device application. The PLC modems are deployed on each PV module and monitor it. The REG aggregates and stores the monitored data from the PLC modems and the inverter. The smart device application retrieves the stored data from the REG to inform users of the status of the PV system. Users can browse and figure out the PV system performance in detail. The proposed system is installed in the field that is composed of sixteen 210W PV modules and a 3kW inverter. This scheme will maintain the performance of a PV system and contribute to enhancing home energy management system.

    ABSTRACT: NAND flash memory has become the dominant secondary storage device for consumer electronics. However, existing data structures and algorithms in modern operating systems are optimized for magnetic disk-based storage device in light of its mechanical nature and NAND flash memory shows different hardware characteristics from magnetic disk. Therefore, a new page replacement algorithm should be designed for NAND flash-based storage device. In this paper, a new page replacement algorithm is proposed for consumer electronics equipped with NAND flash memory as secondary storage device. The proposed algorithm reduces the number of write operations to NAND flash memory by delaying the eviction of cold dirty pages and improves the page hit ratio by evicting the cold pages preferentially. Experimental results show that the proposed algorithm is better than existing page replacement algorithms designed for NAND flash memory in terms of page hit ratio and the number of write operations.

    ABSTRACT: Smart TV has been an increasingly important multimedia device in recent years due to its powerful functionalities that facilitate consuming multimedia contents. In smart TV environment where an interface for controlling multimedia contents is very limited, how to minimize user efforts while interacting with multimedia contents (e.g., searching for a specific video or browsing through images) is the most critical issue. To address this issue, various approaches using voice communication, gesture control, and gaze tracking systems have been proposed; however, their performance is still not satisfactory. In this paper, a new approach for providing multimedia contents to users with minimized human efforts in smart TV environment is proposed. The proposed approach is based on the recent smart TV equipped with a standard mouse as a remote controller and exploits a novel algorithm to infer user's search intent from mouse movement patterns, thereby improving the speed and accuracy of the contents search in smart TV environment. The experimental results show the strength and potentials of the proposed approach and further research directions.

    ABSTRACT: Memory deduplication, which can remedy memory scarcity in mobile systems, can hardly be used due to its high computation cost. This paper proposes a computation efficient memory deduplication scheme that avoids unnecessary computations for memory deduplication. To make it efficient, the proposed scheme gets rid of pages, which are unlikely to be deduplicated, from the target of memory deduplication. This exclusion is performed in time-domain and in space-domain by exploiting the characteristics of mobile applications. The prototype implementation shows significant computation cost reduction while providing the same memory savings as in previous approaches. The saved memory is used for improving application launch time as well.

    ABSTRACT: Internet protocol television (IPTV), which is rapidly growing in popularity, can provide hundreds of channels; but the very number of channels, and the delay in switching between them due to network bandwidth limitations, can make it difficult for viewers to find the content they want. To address these problems, this paper presents a novel scheme that identifies 'hot' channels, those likely to be watched in the near future by a target viewer. Then, the scheme actively maintains a list of hot channels, and a second list of cold channels. Channels are allocated to one of the lists based on their recent popularity across all IPTV viewers and the target viewer??s own viewing history. The hot list is searched first during channel navigation, and hot channels are also prefetched in low resolution to support a preview mode; this combination usually reduces zapping time substantially, even if network bandwidth is limited. A prototype architecture of the proposed scheme is developed. Experimental results show that the proposed scheme significantly improves channel seek time compared to adjacency-based prefetching, popularitybased prefetching, popularity-based arrangement, or a simple numerical ordering.

    ABSTRACT: Mobile device-centric multi-device collaborative computing has been proved as an optimal alternative, which satisfies the mobile users?? increasing expectations towards richer people-centric computing services on mobile platforms. However, many non-smart embedded devices, which are characterized by poor processing power and limited wireless network connection capabilities, are not utilized effectively in current collaborative computing paradigm yet. In this paper, a universal mobile platform, Ver-Comp (Versatile Companion), with a dedicated processor, wireless connectivity and customized mobile OS (Operating System), is proposed to serve as the smart companion device of various non-smart electronic devices (such as digital camera, printer, electronic toy, microwave oven, heart rate monitor and etc.). Non-smart embedded electronic devices are therefore turned to be smart objects so as to cooperate with current smart mobile devices or cloud platforms seamlessly. The processing capabilities of current smart mobile devices are thus augmented indirectly and their battery lives are also extended significantly by migrating partial tasks to the smart objects. In order to meet the requirements of high energy efficiency and quick boot time, an uneven-dual-core architecture processor with multi-OS support is proposed. Furthermore, a Multipleclient Raindrop File System (MRFS) and a File Allocation Table eXtension (FAT-X) file system are also developed to make the data synchronization and virtual access across multiple heterogeneous computing platforms easy and flexible. Finally, three fascinating applications are implemented to demonstrate the flexibility and promising usage of the proposed platform.
