Novel Hybrid Content Synchronization Scheme for Augmented Broadcasting Services

Abstract

As a new hybrid broadcasting service, augmented broadcasting shows enhanced broadcasting content on a large TV screen, while augmented reality (AR) on a mobile device augments additional graphical content onto an input image from the device's own camera to provide useful and convenient information for users. A one‐sided broadcasting service using AR has already been attempted in virtual advertisements during sport broadcasts. However, because its augmentation is preprocessed before the video image is transmitted, the viewer at home may have no influence on this formation; and no interaction for the user is possible unless the viewer has a direct connection to the content provider. Augmented broadcasting technology enables viewers to watch mixed broadcasting content only when they want such service and to watch original broadcasting content when they do not. To realize an augmented broadcasting service, the most important issue is to resolve the hybrid content synchronization over heterogeneous broadcast and broadband networks. This paper proposes a novel hybrid content synchronization scheme for an augmented broadcasting service and presents its implementation and results in a terrestrial DTV environment.

Augmented reality tools for sports education and training

“…The Hawk-Eye system is the most recognized example of AR systems that is no longer limited to electronic line-calling feature, and has been extended to be used for coaching tennis or cricket. Therefore, augmented broadcasting technology allows viewers to see relevant content and match information (S. Kim, Choi, Jeong, Hong, & Kim, 2014). In this line, Monji-Azad, Kasaei, and Eftekhari-Moghadam (2014) proposed an AR method for adding information to sports scenes from a single moving camera.…”

S/W Based Frame-Level Synchronization for Irregular Screen Processing System

“…The main algorithm comes from the non-concurrent transmission of a sync signal to every slave for display using a predictive scheme, and the optimal framework to be synchronized among the frames. On the master side, all signals from the slaves to the master, and the master itself, are updated for generation of the linear prediction model for the display time of each terminal including the master, and the optimal sending time for a sync signal to be used for a display is determined through (12).…”

“…Multi-screen environments are now becoming an important part of digital signage where various types of screens are employed [5]- [12]. However, to provide synchronized screens, a dedicated hardware (H/W) device is generally required for multi-screen environments.…”
