A user has several personal computers, including mobile phones, tablets, and laptops, and needs to watch live camera feeds from and videos stored at any of these computers at one or more of the others. Industry solutions designed for many users, computers, and videos can be complicated and slow to apply. The user must typically rely on a third party service or at least log in. The Personal Video Distribution (pVD) system supports sending and viewing live and stored videos between any of a single user's computers, and allows for a smooth handover of play back between computers. The system avoids any third parties, and relies only on the user's personal computers. We present the architecture, design and implementation of the pVD prototype. The architecture is comprised of functionality for sending videos, subscribing to videos, and maintaining the video play-back state. The design has a local side sending and viewing videos, and a global side coordinating the switching and distribution of videos, and maintaining subscriptions and video state. The prototype is primarily done in Python. A set of experiments was conducted to document the performance of the prototype. The results show that pVD global side has low CPU usage, and supports a handful of simultaneous exchanges of videos on a wireless network.

“…To overcome these limitations, PVRs connected to broadband receive broadcast programs from central servers even though they have not stored the programs in their storage space [4]. To provide these networked PVR services with a large number of concurrent users in real time, it is essential to provide sufficient network bandwidth and fast responses to interactive operations.…”

Distributed appliances connected to the Internet have provided various multimedia services. In particular, networked Personal Video Recorders (PVRs) can store broadcast TV programs in their storage devices or receive them from central servers, enabling people to watch the programs they want at any desired time. However, the conventional CDNs capable of supporting a large number of concurrent users have limitations in scalability because more servers are required in proportion to the increased users. To address this problem, we have developed a time-shifted live streaming system over P2P networks so that PVRs can share TV programs with each other. We propose cooperative buffering schemes to provide the streaming services for time-shifted periods even when the number of PVRs playing back at the periods is not sufficient; we do so by utilizing the idle resources of the PVRs playing at the live broadcast time. To determine which chunks to be buffered, they consider the degree of deficiency and proximity and the ratio of playback requests to chunk copies. Through extensive simulations, we show that our proposed buffering schemes can significantly extend the time-shifting hours and compare the performance of two buffering schemes in terms of playback continuity and startup delay.

“…As the number of IPTV subscribers increases, the client/server architecture thus causes high expense for expanding network capacity by adding proxy servers to accommodate all the increasing subscribers [ 1 ]. The personalized IPTV services including time-shifted TV may make it even more difficult for IPTV systems to manage network traffic efficiently [ 2 , 3 ].…”

With advent of various mobile devices with powerful networking and computing capabilities, the users' demand to enjoy live video streaming services such as IPTV with mobile devices has been increasing rapidly. However, it is challenging to get over the degradation of service quality due to data loss caused by the handover. Although many handover schemes were proposed at protocol layers below the application layer, they inherently suffer from data loss while the network is being disconnected during the handover. We therefore propose an efficient application-layer handover scheme to support seamless mobility for P2P live streaming. By simulation experiments, we show that the P2P live streaming system with our proposed handover scheme can improve the playback continuity significantly compared to that without our scheme.
