A new algorithm to compute precise depth estimates for motion stereo is described. Input data is obtained from a single CCD camera and a moving belt. It is shown that the problem of matching among multiple motion stereo images can be effectively carried out by use of adaptive correlation matching. Experimental results with real stereo images are presented to demonstrate the performance of the algorithm.

As broadcasting and communications convergence is coming, DMB terminals have progressed to network-enabled (CDMA, WiBro, HSDPA, 4G, WLAN, and so on), and more storage and processing capability equipped devices. According to the progress, more rich and user-centric service with communication network and personalized consumption based on metadata and storage are requested . To fill the bill, this paper propose personalized DMB bidirectional contents and metadata server, especially using DMB AF and TV-Anytime metadata.

In this paper, we propose a new wearable gaze tracking system based on the glasses-frame-based device which includes an eyecapturing camera. Gaze positions are calculated based on the geometric transform. Also, errors caused by facial movements are compensated by using the geometric relation of two corneal specular reflections. Menu selection is implemented based on the dwell time of gaze position. Experiments are performed in order to confirm the feasibility for applying the proposed method to internet protocol television (IPTV) with large scaled screen. Experimental results showed that the average root mean-square (RMS) error of gaze detection under allowing facial movements was 1.38 degrees.

Data broadcasting has became to be an important role in providing users with multi-media data including rich information as the broadcasting environment is evolving from analog to digital. Data broadcasting provides users with the interactive and enhanced services by sending data elements in broadcast television transport. Data applications deliver the additional and useful information to viewers with a various type

DTV data broadcasting offers broadcasters the new business model to acquire considerable revenue from digital broadcast. When the broadcasters integrate and maintain the data broadcast station system, they encounter the cost to be paid unnecessarily because there is no common interface specification among the equipments of DTV station system. This paper describes the flexible and open interface that will decrease the wasteful expenses in moving the transition to data broadcast station system.

The personalized service becomes an important role in consuming the mobile broadcasting contents due to the lack of television watching time in the mobile environment. The paper proposes personalized broadcasting system to provide user with three kinds of the personalized broadcasting service such as contents tracking, time shifting and contents scraping according to user preference.

Digital broadcasting environment in which digitalized AV contents can be sent has a room for data transmission as well. In this circumstance, effective encoding method of verbose XML type TV-Anytime metadata becomes important and also the broadcasting environment-specific refinement of TV-Anytime transportation specification is in great need. This paper suggests a well-tuned framework for encoding TV-Anytime metadata. Our TV-Anytime codec, the main subject of this paper, includes revision of the whole TVA codec system specification and external programming interfaces to communicate with the external modules in our unidirectional broadcasting head-end system.
