networked digital Video Recorders and social networks
Consumer Communications and Networking Conference, 2010Co-Authors: Herkko HietanenAbstract:Digital Video Recorders (DVR) are getting connected to the Internet. There are several ways to engineer networked DVRs. Consumers can store the recordings at home or to remote cloud storage service. The recorder software can be implemented to respond to consumers' or rights owners' needs. The most common DVRs have been home based Recorders that respect at least some of the rights owners' interests. However, the cloud model is developing traction as broadband becomes more common. The new technology changes markets and courts have to define the limits of place- and time shifting. Networked DVRs open a door for social enrichment by viewer communities, but also threaten the whole business model of advertisement-based television. Networked DVRs can potentially change the centrally controlled broadcast economics of television into decentralized Internet economics.

business models and programming choice digital Video Recorders shaping the tv industry
Americas Conference on Information Systems, 2005Co-Authors: Claudia Loebbecke, Stefan RadtkeAbstract:This paper focuses on the influence that Digital Video Recorders (DVRs) are expected to have on the business models and in particular the programming choice of TV stations and cable / satellite TV service providers. After presenting the theoretical underpinnings with respect to programming choice modeling for the TV industry, this work examines DVRs in detail covering their main product features, impacts on viewer behavior, and the current roll-out status. This paper then investigates how these DVR features impact earlier insights from programming choice modeling and how they lead to changed business models for TV stations. The paper concludes with a brief summary and a critical outlook for a TV industry business model.

ECIS - Digital Video Recorder Driven Impacts on the Video Content Services Industry
2004Co-Authors: Claudia LoebbeckeAbstract:Being part of a larger research program, this paper focuses on the impacts of so-called 'Digital Video Recorders' (DVRs) on the Video content services industry. First, it gives a succinct definition of the Video content services industry using the value chain as a metaphor. After laying a brief theoretical foundation on technological change and adoption, it considers the technological factors 'increased broadband connectivity to the home' and 'increased storage capacities' as change drivers in the Video content services industry. The paper then highlights DVRs in detail (features, history, evolution, and viewer behavior) and investigates implications of a DVR roll-out for the different value propositions of players in the industry. It concludes with a brief outlook for the industry in the light of new technological developments.

Real-time Video watermarking techniques robust against re-encoding
Journal of Real-Time Image Processing, 2017Co-Authors: Gilsang Yoo, Hyeoncheol KimAbstract:This paper presents a real-time watermarking codec that is robust against re-encoding attacks for high-definition Videos. The codec uses a segmentation function and texture detector techniques for applying real-time watermarking to human visual systems. Experimental results confirm that the proposed scheme satisfies the requirements of invisibility, real-time processing, and robustness against format conversion and low bit-rate encoding. The proposed algorithm has the advantages of simplicity, flexibility, and low computational burden; thus, it is a suitable candidate for many novel and interesting applications such as Video fingerprinting for set-top boxes, Internet protocol television, personal Video Recorders, and satellite boxes.

high performance and high reliable file system for car digital Video Recorders
International Conference on Consumer Electronics, 2015Co-Authors: Younghun Kim, Dongkun ShinAbstract:Car digital Video Recorders store real-time audio/Video data at flash memory storage devices. They require high performance and high reliable file systems. However, current file systems are vulnerable to sudden-power-off and flash memory errors. This paper proposes flash-aware cluster allocation techniques that can reduce the probability of file system corruptions and file fragmentation. Experiments on a real system showed that the proposed techniques can prevent the file fragmentation and can improve the write performance and SD card lifetime significantly.

Improving file system performance and reliability of car digital Video Recorders
IEEE Transactions on Consumer Electronics, 2015Co-Authors: Younghun Kim, Dongkun ShinAbstract:Car digital Video Recorders (DVRs) store realtime audio/Video data at flash memory storage device. Car DVR should handle a large amount of high quality multimedia data with high reliability. However, current file systems are vulnerable to sudden-power-offs and flash memory errors. This paper proposes flash-aware cluster allocation techniques and a flash-aware journaling technique. The flash-aware cluster allocation techniques can reduce the probability of file system corruptions and file fragmentations. The flash-aware journaling technique can ensure the file system consistency without significant overheads. Experiments on a simulator and a real system showed that the proposed techniques can prevent file fragmentations and file system corruptions, and they can improve the write performance and lifetime of SD card significantly.
