We propose a fully automatic and computationally efficient framework for analysis and summarization of soccer videos using cinematic and object-based features. The proposed framework includes some novel low-level processing algorithms, such as dominant color region detection, robust shot boundary detection, and shot c…

In this survey, we present state-of-the-art bitrate adaptation algorithms for HTTP adaptive streaming (HAS). As a key distinction from other streaming approaches, the bitrate adaptation algorithms in HAS are chiefly executed at each client, i.e., in a distributed manner. The objective of these algorithms is to ensure…

The average US consumer watches TV for almost five hours a day. While the majority of viewed content is still broadcast TV programming, the share of the time-shifted content is on the rise. One-third of US viewers currently use a digital video recorder like device, but trends indicate that more consumers are migrating…

This work advances our understanding of children's visualization literacy, and aims to improve it through a novel approach for teaching visualization at elementary school. We first contribute an analysis of data graphics and activities employed in grade K to 4 educational materials, and the results of a survey conduct…

For pt. 1 see ibid., vol. 13, no. 1, p.70-5 (2009). In this second part of a two-part article, the authors highlight the impact that different durations of IP packet loss have on the quality of experience for IP-based video streaming services. They describe the visual impairments that result from such packet losses an…

HTTP adaptive streaming with chunked transfer encoding can be used to offer low-latency streaming without sacrificing the coding efficiency. While this allows a media segment to be generated and delivered at the same time, which is critical in reducing the latency, the conventional bitrate adaptation schemes make ofte…

The paper addresses automatic scene change detection, key frame selection, and similarity ranking which constitute the main steps of a content based video abstraction system. Unlike other methods, the proposed algorithm performs scene change detection and key frame selection in one step. We treat scene change detectio…

We present a survey of transport methods for 3-D video ranging from early analog 3DTV systems to most recent digital technologies that show promise in designing 3DTV systems of tomorrow. Potential digital transport architectures for 3DTV include the DVB architecture for broadcast and the Internet Protocol (IP) archite…

Internet protocol television (IPTV) is gaining recognition as a viable alternative for the delivery of video by telecommunications and cable companies. It features bandwidth efficiencies, and management; therefore, it is ideally suited for broadcast, multicast, unicast interactive and multimedia services (IMS - IP mul…

Our earlier Low-on-Latency (dubbed as LoL) solution offered an accurate bandwidth prediction and rate adaptation algorithm tailored for live streaming applications that targeted an end-to-end latency of up to two seconds. While LoL was a significant step forward in multi-bitrate low-latency live streaming, further exp…
