“…It constructs an application overlay appropriate for streaming and provides a continuous playback if disruption occurs. Gallo et al [51] consider all types of video delivery (linear TV, VoD, timeshifted TV (tsTV), network Personal Video Recorder (nPVR)) 1 and propose a distributed system that uses IP multicast, distributed caching, and P2P content exchange for an efficient media content distribution.…”

In this thesis, we considered the effect of the content delivery network architecture on the popular short video sharing websites such as YouTube. The high number of users demanding videos impacts YouTube scalability which requires a new content delivery structure. Considering the high performance of P2P overlay networks, we propose an efficient peer-to-peer based system for short video sharing in the Internet in which all participant peers are responsible to distribute video replicas they have stored. This system comprises of a BitTorrent like network and a central media streaming server. To proficiently utilize P2P in our system, we propose some important approaches including an efficient and reliable indexing scheme, an efficient downloading strategy, a reliable content distribution mechanism, and a fairness policy. The simulations results demonstrate that the proposed system significantly increases client peers download speed while reduces the server workload and the startup delay for an improved playback quality.

“…These systems are based on a predefined achitechture, such as Distributed Hash Table (DHT) or turntable. The use of the hash function in DHT [7,8] seems irrelevant in this context because chunks are iteratively produced. Furthermore, a peer departure conducts to multiple deletions in the DHT.…”

Time-shifted streaming (or catch-up TV) allows viewers to watch their TV programs within an expanded time window. In this paper, we emphasize the challenging characteristics of time-shifted TV systems that prevent known delivery systems to be used. We model time-shifted TV as multiple-interval graph, then we present a Peer-Assisted Catch-Up Streaming system, namely PACUS, where a set of end users' computers assists the server for the content delivery. We show in particular how the PACUS tracker server can be efficiently implemented for catch-up TV. We demonstrate the benefits of PACUS by simulations. We especially highlight that PACUS reduces the traffic at the server side with the advantages of lightweight and self-adaptive unstructured peer-to-peer systems.

“…[10] and [6] propose that the distribution of live video streams is done separately and independently of the time-shifted streams. The use case of seamlessly switching from live to time-shifted is therefore not supported.…”

The popularity of video sharing over the Internet has increased significantly. High traffic generated by such applications at the source can be better distributed using a peer-to-peer (P2P) overlay. Unlike most P2P systems, LiveShift combines both live and on-demand video streaming -while video is transmitted through the peer-to-peer network in a live fashion, all peers participate in distributed storage. This adds the ability to replay time-shifted streams from other peers in a distributed and scalable manner. This paper describes an adaptive fully-distributed mesh-pull protocol that supports the envisioned use case and a set of policies that enable efficient usage of resources, discussing interesting trade-offs encountered. User-focused evaluation results, including both channel switching and time shifting behavior, show that the proposed system provides good quality of experience for most users, in terms of infrequent stalling, low playback lag, and a small proportion of skipped blocks in all the scenarios studied, even in presence of churn.
