## Background
FIELD OF THE INVENTION
The invention relates to methods, systems and computer program products for wirelessly broadcasting advertisements and especially for wirelessly broadcasting advertisements to handheld television receivers.
BACKGROUND OF THE INVENTION
Mobile and wireless communication technologies enable users to receive media content by using handheld devices. Digital Video Broadcasting-Handheld (DVB-H) is a relatively new communication standard. DVB-H enables a handheld television receiver to receive television programs over wireless channels. A brief description of the DVB-H standard and DVB-H compliant systems can be found in the following publications, all being incorporated herein by reference: “DVB-H: Digital Broadcast Services to Handheld Devices”, G. Faria, J. A. Henriksson, E. Stare and P. Talmola, Proceedings of the IEEE, Vol. 94, No. 1, January 2006; “An investigation of and a Proposal for Handover Decision-making in DVB-H”, X. D. Yang, Y. H. Song, O. J. Cosmas, T. Itagaki; and “DVB-H—the emerging standard for mobile data communication”, and M. Korenfeld and U. Reimers, EBU Technical Review, January 2005.
DVB-H networks include DVB-H transmitters, each transmitter wirelessly broadcasts a multiplex of television programs to multiple handheld television receivers that are positioned within a cell. The cell can be expanded by using repeaters, but this is not necessarily so. It is noted that DVB-H networks can also utilize DVB-T transmitters, by applying time division multiplex techniques.
During the last few years, advertisement campaigns are spread among multiple communication channels, including so-called “new” media channels. DVB-H networks can provide a new advertisement platform that will be characterized by high accessibility as well as improved graphic interface.
There is a growing need to provide efficient methods, systems and computer program products for broadcasting advertisements over DVB-H networks.

BRIEF DESCRIPTION OF THE DRAWINGS
The abovementioned and other objects, features, and advantages of the present invention will become more apparent from the following detailed description, when applied in conjunction with the accompanying drawings. In the drawings, similar reference characters denote similar elements throughout the different views, in which:
FIG. 1 illustrates a system and its environment, according to an embodiment of the invention; and
FIGS. 2-4 are flow charts of method for wirelessly broadcasting advertisements, according to various embodiments of the invention.



DETAILED DESCRIPTION OF THE DRAWINGS
The method, system and computer program product utilize the benefits of broadcast technology and addressable advertising. Conveniently, each group of handheld television receivers that are tuned to a certain program receives an advertisement that matches the profiles (viewing patterns, socio-economical characteristics) of the users of that group of handheld television receivers. By dynamically monitoring which users belong to the group and finding a matching advertisement the effectiveness of an advertisement campaign can be increased.
Yet according to another embodiment of the invention the method, system and computer product can compensate for group-based decisions by finding advertisements that are better fitted (better matched) to certain users of the group. If such advertisements are found a request (aimed to the user) to be tuned to another program (in order to receive a better matching advertisement) can be sent. Additionally or alternatively, if such advertisements are found the handheld television receivers of such users can be instructed to be tuned to another program (in order to receive a better matching advertisement).
The better matching advertisement can be detected by correlating between one or more advertisement characteristics (or attributes) to one or more characteristics of the user profile. A certain threshold (or value) can be set in order to prevent frequent requests or instructions. Accordingly, a request or an instruction is sent if the better matching advertisement is better matching by a predefined value. The value can be set to zero or to another positive value.
For convenience of explanation, the following detailed description and associated drawings refer to a DVB-H compliant network. It is noted that the invention is not limited to the DVB-H standard and can be implemented on other networks and on other standards, without falling out of the true spirit of the invention.
