In theory, speech recognition technology can make any spoken words in video or audio media subject to text indexing, search and retrieval. This article describes the News-on-Demand application created within the InformediaTM Digital Video Library project and discusses how speech recognition is used for transcript creation from video, time alignment of closed-captioned transcripts, a speech quer...

Watching movies is an activity that many people do to get rid of fatigue after doing quite tiring daily activities. In the past, watching could only by going cinema with determined showtimes, but as technology develops grow so fast, now possible anytime and anywhere using video on demand. This research background result pre-research which shows there a shifting phenomenon in consumer behavior w...

This study assesses the worst-case demand and replication models for determining the bandwidth required by the origin server when a number of video programs in a videoon-demand system are replicated on replica servers. The bandwidth required by the video-on-demand system determines the number of viewers that could watch video programs simultaneously. If a video program is viewed in its entirety...

With the proliferation of IP networking and wireless access, local exchange carriers (LEC) are under tremendous pressure to evolve into broadband service providers. On-demand video distribution to the mass appears to be one of the best evolution paths for the LEC. Various approaches for providing on-demand content/video distribution to massive viewers are compared. In particular, a novel low-co...

A cost-effective approach to building up scalable Videoon-Demand (VoD) servers is to couple a number of VoD servers together in a cluster. In this article, we study a crucial video replication and placement problem in a distributed storage VoD cluster for high quality and high availability services. We formulate it as a combinatorial optimization problem with objectives of maximizing the encodi...

Users demand for watching high-quality video on the move is increasing day-by-day. Despite of achieving high bandwidth in the fourth and fifth generation of cellular networks, the bandwidth is not sufficient for meeting video-on-demand requests. Device-to-device communication is a way to achieve more spectral efficiency by frequency re-use. On the other hand, Information centric networking is i...

In this paper, we introduce a scalable Video-on-Demand (VoD) system called GloVE (Global Video Environment) in which active clients cooperate to create a shareable video cache that is used as the primary source of video content for subsequent client requests. In this way, GloVE server’s bandwidth does not limit the number of simultaneous clients that can playback a certain video since that as l...

As wireless technology evolves towards its fourth generation (4G) of development, the prospect of offering multimedia services such as on-demand video streaming and video conferencing to wireless mobile clients becomes increasingly more viable. The eventual success of such applications depends on the efficient management of the limited system resources while taking into account the time-varying...

Today's wireless technologies such as IEEE 802.16 (a.k.a., WiMAX) [3] for long-haul communications and IEEE 802.11 (e.g., WiFi) [15] and Bluetooth [5] for short distances are widely deployed. While WiFi is suitable for a small local wireless network, WiMAX (Worldwide Interoperability for Microwave Access) allows for communications over tens of kilometers and, thus, can be used to provide a high...
