IPTV service is a new service which is today offered from almost every Telecom operator. One of the advantages of IPTV service stemming from its architecture is certainly the fact that it is very easy to measure what TV channels are the ones mostly watched. This papers desribes this measurement and analysis results in one Telecom operator in Bosnia and Herzegovina. They describe what TV channels are mostly watched in different time periods. We developed a simple weighting algorithm to order the channels by watching rate. Based on it we are providing extensive tables. This paper forms an industrial contribution with results important for marketing but also is scientific contribution because it introduces one new method of scoring TV channels based on previous measurements in their audience. We also developed IPTV Statistics model and described results from this research for a new statistics model. This paper is the continuous of previously published contributions from this area.

Every organization must have in its IT department a defined level of informational security as well as an administrator role for managing the system. This paper is based on defining the information security in the department for IPTV/VoIP management system of Telecom operator, the leading Telecom operator in Bosnia and Herzegovina. The paper is focused on the comparison of actual and implemented recommendations for the Information Security Management according to ITIL V3 standards in the IPTV/VoIP system of Telecom operator. Based on the conclusion drawn from the paper proposals have been made for the improvement of the management of the informational security in this department of Telecom operator. On this way, the paper will have a both specialized and scientific contribution: specialized through the presentation of recommendations to the management of Telecom operator for the improvement of the informational security in the department of the IPTV/VoIP service management, and scientific through the adjustment of the implementation of ITIL V3 Information Security Management process in the telecommunication industry which is a one of a kind research made in the department of IPTV/VoIP work management service of Telecom operator.

Managing the change plays the most important role in any IT business organization. Managing changes is important for strategic components of the existing IT service. One of such strategic components is the alteration of the Middleware system in the IPTV service of the Telecom Operator. The Middleware system is a central system which controls all other IPTV systems of the Telecom Operator: Video on Demand system, Encrypting system, Headend system, Monitoring system and Database system. That is why, before we uninstall the old and install the new Middleware system we require a set of activities which have to be clearly stated. The reason for swapping the Middleware system can be the common problems and also the inefficiency in the function of the old system. This document describes the steps which need to be implemented in the process of changing the Middleware system in the IPTV system of BH Telecom, the leading Telecom Operator in Bosnia and Herzegovina. The result of the work should be a reflection upon the improvements of the quality parameters of the IPTV system of BH Telecom which are a contribution of the newly implemented Middleware system, which is as a final result going to lead to a increase of users and profit income. This work represents the continuation of the investigation in BH telecom which are conducted with a goal to improve the management over the IT servers.

For the business of an organization to be at a high level, it is necessary to define your relation with an external company (partner) which is going to be helpful in the complete or partial implementation of some project. The main motive for hiring a company as a partner in the process of realization is for finding a high quality solution, and saving your own human resources. The process which deals with the relations between your company and an external company in the IT industry, according to ITIL V3 methodology of leading IT services is Supplier Management. The aim of this document is to describe Supplier Management in the development of IPTV systems in Telecom operator, through the creation of a contract between Telecom operator and a external company which needs to implement and install IPTV systems, and also through the guidelines for performance control of a partnership company by the Telecom operator, during the project of application and installation of the IPTV system. The last chapter of the document includes an comparative analysis of the implementation of Supplier Management through the IPTV system of BH Telecom (the leading telecom operator in Bosnia and Herzegovina) with the recommendation of implementing the same according to ITIL V3 standards. The result of the comparative analysis has to be a sequence of recommendations for the improvement of relations with an external company which has implemented the IPTV system and which is responsible for the initial maintenance of the IPTV system, for the purpose of enabling high quality IPTV services to the end users of this Telecom operator. This contribution represents a continuation of scientific research and application of ITIL V3 standards which is lead in BH Telecom in order to adapt all of the systems under this standard with regard to previously published contributions in this field, a contribution entitled "Implementation of the Information System of the Telecom Operators Using the ITIL V3 Service Methodology for the Service Design Phase" which was published during the SERVICE COMPUTATION 2010 conference. This contribution represents a continuation of research in BH Telecom. The research should provide recommendations for implementation of all ITIL V3 processes in BH Telecom's IPTV system.

In order for any business organization to perform on a successful level, it is necessary that it has a defined set of activities that manage IT processes and services. Defined set of activities constitutes the Service Management of that organization. There are many types of Service Management, and this paper is based on the type of which is called Information Technology Infrastracture Library V3 (ITIL V3). ITIL V3 has a total of five phases: Strategy Service, Service Design, Service Transition, Service Operation and Continual Service Improvement. This paper is focused on the description of its second phase, which is called Service Design. The aim of this paper is to describe information systems development of the Telecom Operator for Service Design phase of the ITIL v3 methodology in all seven of the processes that are contained in these phases. These are: Service Catalogue Management, Service Level Management, Capacity Management, Availability Management, IT Service Continuity Management, Information Security Management and Supplier Management. This paper attempts to show to the telecom operators that during the realization of their IT processes they do not necessarily have to use the eTOM standard, but may use other standards and concretely they can use ITIL V3 standard. This paper in its conclusion, with previously detailed analysis of the implementation of the Service Design processes according to ITIL V3 methodology in the information system of the telecom operator, needs to define which teams are required to implement the Service Design processes and which are the activities that each team has during the implementation of the information system of the telecom operators. Keywords-ITSM, ITIL V3, Service Design, Service Catalogue Management, Service Level Management, Capacity Management, Availability Management, IT Service Continuity Management, Information Security Management, Supplier

The need for more cost-effective, accurate and efficient methods of using geospatial information has been around a long time. However, development of GIS software solutions and information technologies enabled the distribution, access and manipulation of geospatial data over the Web. In this paper is represented a new access to geospatial data and the possibility of integrating geospatial data with other business intelligent systems in standard and modern, Web-oriented, GIS applications. The paper reveals the motivation to show how geospatial data can be integrated into the Web environment platform and make it available to a large number of users. This paper represents the new method called GeoREST which is based on the principles of Services Oriented Architecture (SOA), or widespread Representational State Transfer (REST) architecture for geospatial data. The proposed method called GeoREST defines new principles for manipulation with geospatial data, which will provide new ways of integration and distribution of geospatial data. This method provides an easy and open access to all types of geospatial resources through a uniform interface. GeoREST method opens new possibilities in the use of geospatial resources, both in standard desktop or Web applications, as well as business information systems. Geospatial service GeoREST API is developed and based on GeoREST method, and it defines the required application interface for simple and open access, manipulation and analysis of geospatial data. The practical implementation of services is made within the project georest.org.

This paper proposes and discusses a GIS that integrates geographic resources with business intelligence data from SAP, TIS and other systems. Location is a unifying theme in business. Location can be an address, a service boundary, a sales territory, or a delivery route. All these things can be visualized and interactively managed and analyzed in a GIS. Spatial relationships, patterns and trends reveal invaluable business intelligence and bring easy-to-understand visualization to business applications. Use GIS to answer basic or sophisticated question on how to improve businesses workflow, management, and ROI (Return on Invest). To be able to integrate GIS system with other business systems and processes, it is necessary that spatial and non-spatial data are "no different". In presentation I will present GIS application which demonstrates concept of integrating data and systems with spatial and non spatial data. The application integrates data from different systems: traditional GIS data, TIS and SAP. Data integration enabling easier and more effective control of telecommunication networks, supervising and effect solutions of failures on element telecommunications systems, access networks and networks features, better controlling systems, witch we afford to end users. Goal is faster and more quality solutions of user's request. Present solutions in this paper based on OpenGIS standards and interfaces to geospatial information providers, Oracle Database and Application Server.

When talking about geospatial technologies, we usually mean tools that interact with geospatial data. Interaction occurs on several fronts: creating, converting, manipulating, or visualizing data. These are the common categories of tools. Parallel to these are developer-focused tools in the form of programming libraries, allowing a deeper level of interaction. An the leading engineering GIS platform for creating and managing spatial data, AutoCAD Map 3D software bridges computer-aided design (CAD) and geographic information systems (GIS) by providing direct access to data, regardless of how it is stored, and by enabling the use of AutoCADreg tools for maintaining a broad variety of geospatial information. Using open source FDO Data Access Technology, Map 3D natively accesses spatial data stored in relational databases, files, and web-based services-providing easy management of large geospatial data sets, while streamlining entire workflows. With smooth integration of Autodesk MapGuidereg technology, AutoCAD Map 3D is the quickest way to publish data to the web or intranet. This paper describes how to build Spatial Web applications, using Open Source tools and implementation in urbanism.
