Many fast motion estimation algorithms have been proposed in order to facilitate the real-time application of H.264 standard. Due to the need of developing the High Performance Video Codec (HVC), this is the time for us to review the best available fast group of algorithms and add novelty into it to make the deployment for future standards, such as the H.265. In this paper, we propose a scheme-based motion estimation algorithm which is able to describe the characteristic of block motion activities through the information of motion vector prediction from the previous frame. With the aid of this information, different search strategies can be carried out. Also, this algorithm is able to skip and save unnecessary motion search of small block types. Experimental results shows that the proposed algorithm is able to speed up the motion estimation time for almost 1.8 times compared to EPZS, but with a similar RD performance.
为了便于H.264标准的实时应用，人们提出了许多快速运动估计算法。由于开发高性能视频编解码器(High Performance Video Codec, HVC)的需要，现在是我们回顾现有的最佳快速算法组并添加新颖性的时候了，以便为未来的标准(如H.265)进行部署。本文提出了一种基于方案的运动估计算法，该算法能够通过前一帧的运动矢量预测信息来描述块运动活动的特征。借助这些信息，可以执行不同的搜索策略。此外，该算法还可以跳过和节省不必要的小块类型的运动搜索。实验结果表明，与EPZS相比，该算法的运动估计时间提高了近1.8倍，但RD性能相近。

DVB's second generation cable transmission standard DVB-C2 introduces OFDM (Orthogonal Frequency Division Multiplex) to cable networks. Whilst its advantages are well-known in various transmission media, such as in terrestrial transmission, OFDM offers benefits also for cable transmission. Examples are the capability of becoming completely independent of an existing channel raster by a scalable signal bandwidth and the high robustness of the DVB-C2 system with respect to various kinds of distortions occurring in today's cable channels. Such features emphasize the role of DVB-C2 as a potential successor for digital transmissions in cable systems. This document focuses on the impact of interferers on the system performance of DVB-C2. The presented results can be used to optimize the parameter set of DVB-C2 for highest robustness in future applications.

Leader-based protocols have been proposed for wireless networks such as 802.11 as an alternative approach to MAC layer ARQ. If based on feedback cancellation, such protocols may achieve low latency and high throughput at predictable reliability and superior scalability with respect to the number of subscribers. Especially for delay-bounded multicast A/V transmission these properties are highly desirable. The authors have proposed such schemes to the IEEE task group TGaa, which is dedicated to introducing more reliable multicast to 802.11 wireless LANs. This paper provides results on wireless feedback cancellation probabilities derived from real measurements with consumer hardware as well as simulation data.

This paper presents a noise-robust super-resolution algorithm. In learning phase, a dictionary classified according to noise level is constructed, and then a high-resolution image is synthesized using the dictionary in the inference phase. Experimental results show that the proposed algorithm outperforms the existing algorithms even for noisy images.

Due to its narrow acoustic bandwidth, typical telephone speech is poorly intelligible on a phoneme or syllable basis. Artificial bandwidth extension (ABWE) techniques intend to increase speech intelligibility by estimating and reconstructing higher frequency components up to 7kHz. Hands-free systems in automotive environments could especially benefit from that, since drivers are mentally stressed during telephone conversations. By improving speech intelligibility, their mental load may decrease. Thus driving safety and comfort increase. This paper presents a real-time ABWE implementation integrated into an automotive hands-free system. Its novelty is a phoneme-specific design that yields an improved performance on critical phonemes, especially /s/ and /z/. Hence, typical lisping effects of previous ABWE approaches are reduced. We performed informal listening tests on meaningless vowel-consonant-vowel (VCV) syllables demonstrating a significantly improved fricative intelligibility of ABWE speech vs. NB speech.

Since embedded systems and consumer electronic devices are popular now, they have adopted huge-capacity storage systems such as flash-memory cards or solid-state drives (SSDs). Many embedded database systems(EDBS) also emerge for the maintenance of data on these storage systems. However, it is complicated and time-consuming to modify an application with one embedded database system to a new one with another embedded database system. In the paper, we will design a middleware for multiple embedded database systems by considering their different interfaces and overhead. With the help of the middleware, it is convenient for users to write applications that can easily adopt various embedded database systems. Furthermore, the middleware can leverage various embedded database systems for better performance and reasonable cost.

Consumer devices containing digital storage are increasingly connected to networks in or outside of the home (e.g. mobile phones, set top boxes (STBs) and network attached storage (NAS). As consumer devices using digital storage are increasingly networked it becomes possible to discover and manage content on these devices. Increased network connectivity allows "global" storage management of user generated as well as commercial content by consumers. This management will allow efficient backup and recovery of data as well as deduplication to speed backup and conserve digital storage space. If combined with automated metadata generation tools, the resulting indexing information will also allow more effective identification and use of consumer content. A form of virtualization of storage volumes in the home would be possible resulting in a consumer storage "cloud" that would effectively manage this content and could also be affiliated with non-consumer and non-local storage "clouds" for even broader content access and use.

There are some leakage radiations from human body depending on incoming signals to it. As there are many noises in the frequency band spanning several MHz, human body communication (HBC), which is a technique to transfer various information through the human body as a communication channel, requires a limitation of frequencies and data rates to support a reliable network that can cope with interference from adjacent users and electrical devices. This paper proposes a frequency selective baseband transmission (FSBT) for HBC. FSBT requires no RF/IF components or overhearing in sleep mode as a service based on Touch-And-Play (TAP). The proposed HBC system supports high reliability, low power consumption, and low cost through FSBT. We achieved a biterror rate of 10–6 at 2 Mbps without forward error correction and verified the functions of the prototypes to transfer streaming data or image files between ultra-mobile PCs, or an ultra-mobile PC and printer.

IPTV provides IP broadcast and VOD, and enables users to access thousands of video content of both types. On the other hand, it is difficult for users to find video content that matches their preferences amongst this huge amount of available content. We propose a video content recommendation system with using a widget application, which can recommend video content related to the content that the user is currently watching. We implemented the proposed system in an experimental system and conducted subjective assessments using the system. This paper describes the system and discusses the experimental results.
