We present a fast decoder for free-viewpoint video navigation. Our free-viewpoint video data consist of simultaneously recorded video streams captured with multiple cameras plus additional dense correspondence information. Neither the size nor the representation of the data is appropriate for realtime rendering. We propose a data compression approach for multi-view video sequences that allows for a real-time decoding and playback of long sequences from hard drive.

In scalable video coding, temporal scalability adopts the inter layer prediction coding structure to increase the coding efficiency. However, any lost single bit in base layer or lower enhancement layer may result in the loss one or more frames and serious visual quality degradation in the decoded image at the receiver. To preserve good image quality, the error concealment algorithm is necessary for scalable video transmission. Some error concealment techniques adopt the motion vector correlation of inter layer in temporal scalability to conceal the damaged motion vector. As the GOP size increases, the inter layer correlation becomes weaker, thus the concealed image quality is decreases. This study proposes two methods to solve this problem. The first method uses the adoptive weighting of motion vectors in forward and backward reference frames to increase the accuracy of motion vector recovery. The other method employs the polynomial function to describe the motion vector correlation between the inter layer and the neighboring blocks. The experimental results show that these methods are effective to conceal the lost block. The concealment efficiency of the polynomial function of motion vector correlation is better than other methods 3.05–2.16dB when GOP size increases.

This paper describes a method to stabilize video for vehicular applications based on Harris features and adaptive resolution. Lucas-Kanade method is applied to match feature points of consecutive frames and construct the feature motion flow. A damping filer is utilized to model the unwanted motion and global motion is separated by extracting oscillation. 92% correct rate with 0.54 second per frame is achieved. The provided benchmark shows outperformance of the proposed method.

This paper introduces an intermediate service platform architecture for home network services. The platform is composed of two layered platforms: the home network management platform and the service management platform. The former provides the common functions necessary for all home network services, while the latter provides the corresponding functions necessary for specific services. The functions enable both users and service providers to enjoy or provide many kinds of home network services flexibly. We use the platform to implement various service applications in an experimental house, and assess the validity of the platform through its operation.

This paper presents an approach to create Linux Device Driver Framework which will be used for representation and control of DTV related HW components found in Set-top boxes (STB) and TV sets (iDTV). During previous years LinuxTV was established as promising architecture for PC TV cards, but from the announcement of Linux DVB API v3 there was no progress toward embedded systems. Therefore, attempt is made to improve and replace existing Linux DVB paradigm, and to introduce concepts applicable and optimized for embedded systems. Layered SW architecture is developed, which simplifies Kernel Drivers development, and export well defined APIs to user space applications.

In this paper we present a novel software-based home control platform as an add-on to a set-top box (STB) for digital television. By means of using merely a remote controller, traditional STB users become able to control lights, appliances and media playback in their homes. Intelligence and awareness is achieved with a support for execution of recipes — pre-prepared scripts that define timely actions and respond to triggers obtained from sensors. Software abstraction layer facilitates integration of any desired communication protocol. In our prototype, we supported Zigbee and DMX for light control, X10 for light/appliances control over power line, as well as Ethernet-based optical cameras as motion / presence sensors and UPnP / DLNA based equipment for distributed media playback.

In this paper, a novel low-power Viterbi decoder with soft decision is proposed. For the branch metric of the Viterbi decoder, our design employs a soft-decision method to improve its correction capability. In order to find the survivor path efficiently, we modify the classical Viterbi decoding algorithm into a new one. This new algorithm is similar to the register-exchange method with lower latency, but using RAM instead of register banks for recording the output bit-stream of the survivor path. Hence, our design can provide a low-power design. Finally, the chip of this design consumes about 28.6K gates using TSMC 0.18 μm CMOS technology. The power consumption of our chip is about 19.5mW at 100MHz.
