1. Introduction As the demand for Internet-based applications grows around the world, Internet Protocol Television (IPTV) has been becoming very popular. Mobile IPTV allows the users to receive multimedia contents over mobile IP networks using unicast, multicast or peer-to-peer (P2P) communications whenever they want and wherever they are. Common Mobile IPTV services include Live TV and Video-o...

One of the concerns users have to confronted when using IPTV system is information overload that makes it difficult for them to find a suitable content according to their personal preferences. Recommendation service is one of the most widely adopted technologies to alleviating this problem; these services intend to provide people with referrals of items they will appreciate based upon their pre...

In this paper, we present an open wireless IPTV development platform which provides a cost-effective and realistic environment for testing and developing video transmission technologies and services. We describe the components of the platform and give examples of how the platform has been used. The platform supports video delivery to mobile users in various networks, e.g., WLAN, WiMAX, and 3G. ...

In this paper we investigate the influence of the video format and of re-scaling on the perceived video quality in the context of IPTV. Addressed resolutions are typical of IPTV: Standard Definition (SD, 720 x 576 pixels) and High Definition (HD, 1920x1080 pixels). Re-scaling comprises SD to HD (4:3, 1350x1080) upscaling and cropping from HD 16:9 (1920x1080) to HD 4:3 (1350x1080) format. In par...

A heterogeneous wired and wireless network architecture is considered for home networks to support Internet Protocol TV (IPTV), voice, and data, the so-called triple-play services. To satisfy the quality of service (QoS) requirements for different traffic classes, class-based queueing (CBQ) is deployed at home gateways and routers. To estimate the network capacity and decide on an appropriate r...

IPTV video services are increasingly being considered for delivery to mobile devices over broadband wireless access networks. The IPTV streams or channels are multiplexed together for transport across an IP core network prior to distribution across the access network. According to the type of access network, prior bandwidth constraints exist that restrict the multiplex data-rate. This paper pre...
