Interactive Videos in IPTV using Hypervideo Links

Abstract

[EN] One of the main advantages of Internet Protocol Television (IPTV) is the capability of full duplex communication between the Television (TV) provider and the clients which permits the interactivity of both. From this interactivity, TV providers can obtain extra information from clients. Moreover, clients can even take profit from this type of communication that allows them surfing between videos. However, this feature cannot be used in Digital Terrestrial Television (DTT). This paper shows the design and development of an interactive video for IPTV services that contains hypervideo links with additional information and content that is very useful for viewers. Furthermore, we detail the protocol used to maintain the service between the TV provider and the clients to maintain the service. Finally, the system is tested in a real scenario and the resulting measurements are provided in order to evaluate the network performance needed to offer an adequate service to each client because according to results shows, the use of hypervideo links does not imply an important increase in the ratio of packets per second.
