Abstract: In a system for scheduling content items accessible to a receiver having a processor (120), at least one type of memory (150, 160, 170) bi-directionally connected to the processor (120), a data receiving block (110), an A/V block (130) for transmitting an output A/V signal, and external interfaces (140), the processor (120) comprises a schedule parameters module (121) for receiving and processing user's parameters input, a schedule search module (122) for searching local or remote schedule databases using parameters defined by the schedule parameters module (121) and a module (123) for adjusting and presenting content items to a user. These three modules (121, 122, 123) in another embodiment of the system can be separate modules placed outside the processor (120).

Abstract: In a system for retrieving content accessible to a television receiver (101) communicating with at least one search engine enable to retrieve the content accessible to a television receiver (101), a content service manager (120) configured to receive a content service display request for a chosen content service identifier comprises a query combiner configured to generate a combined query by combining a current user interest query with a service query assigned to the requested service identifier, a search engine interface configured to send the combined search query to the search engine and receive content search results from the search engine as well as a content presenter configured to present the content search results to the user.

Abstract: A system for distributing content to client applications in a networked environment encloses a base content host having an application server providing base content responsively to requests from client applications. The base content (242) comprises at least one special element, referenced by a special locator pointing to a special content (252), the special locator generated by a special locator generator (243) of the base content host (240). The special locator distinguishes by a special locator host domain name consisting of a sequence of characters of which at least one is randomly generated, followed by an existing top level domain name. Apart from the base content host (240) the system comprises at least one special content host (250) having a special content host IP address and comprising an application server (251) providing the special content (252), responsively to requests from client applications.
