abstract = {Video coding is a process for adapting media content to the constraints of transmission networks delivery and terminal device visualization. Moreover, content protection is also necessary. Nowadays the heterogeneity of client devices is increasing leading to different resolutions, qualities and form factors. Due to this, transcoding and protection are essential processes to be conducted in modern video distribution networks to adapt video to devices and network constraints and to enable pay per quality schemas enforcing content licenses. Unfortunately, transcoding and protection can be no longer considered linear since every single content should be transcoded in several formats and sometimes protected, so it would require a long time to finish. Modern scalable coding techniques, as H264 SVC, can help to save processing power and bandwidth providing in a single stream several video versions. However, if the enhancements of a SVC encoded content are protected separately, it would possible to enable pay-per-quality providing an additional degree of freedom to content delivery industry. Unfortunatelly, transcoding and protection entail huge doses of processing power at provider side and should be distributed. Moreover, processing key streams to decrypt enhancements that were encrypted separately can increase the complexity at receiver side. Cloud computing emerges as a potential solution for coping with large population of users with heterogeneous visualization devices. The elastic nature of cloud computing can be an advantage given the difficulty to predict the computing resources video content would require to be distributed during the entire content life. This article describes a system that distributes and parallelizes the video transcoding process as well as the content encryption, following the SaaS approach in cloud computing. Moreover, the article describes an experimental approach for generating and processing a flexible key stream that would help to simplify key management at receiver side and would allow legacy receivers to consume SVC content with separate enhancement protection.},

abstract = {The great variety of consumer electronic devices with support of wireless communications combined with the emerging Cloud Computing paradigm is paving the way to real anytime/anywhere computing. In this context, many services, such as music or video streaming, are delivered to the clients using Cloud-based providers. However, service continuity when moving across different terminals is still a major challenge. This paper proposes SuSSo, a novel middleware architecture that allows sessions initiated from one device to be seamlessly transferred to a second one, as might be desirable in the enjoyment of long running media.},

abstract = {IPTV services are available in many flavors. There are two main trends: vertical IPTV platforms on the Internet with user unrestricted access and standard platforms that belong to closed systems (users need to contract the access). The substantial differences and incompatibilities among the different types of platforms have brought the appearance of a plethora of different user technologies and systems that require non-professional users to deal with different devices and hampers the interchange between vendors. This work approaches the problem of dealing with vertical platforms providing a flexible horizontal self-configuring STB architecture.},

abstract = {There are lots of devices and services inside a home which have to be managed. OSGi platforms alleviate this management by installing some services on a gateway located at home. A service provider might manage those services as part of a package of services. In general, OSGi platforms are connected to centralized repositories facilitating the maintenance by service providers. However, when various service providers work on a given gateway the number of services and components installed in it increases. This sometimes leads to inconsistencies as duplicate components that might cause performance problems or service interruptions. This paper presents a system for analyzing and automatically optimizing the components deployed on a OSGi home gateway.},

However, devices within home environments are shared among family members, making personalization complex. This article describes a system that uses presence detection through several low cost cameras. It uses a centralized repository for personalization and an event based protocol for configuring devices surrounding users. The system addresses privacy-based filtering and group preference modeling.},
