Increased interactivity is a general tendency for telecommunication services today, an aspect, which is also reflected in the more traditional distribution services like television. The broadcasting has been handicapped by the limited capacity of analog delivery and one-way delivery. In the transition to digital TV broadcasting infrastructures rapidly, all people want to experience new services such as interactive data broadcasting and to choose, sort, order, store and manipulate what they receive on their same terminal at home. Consequently, we propose the design of Web-based return channel system, which is so called WRCS. This is aim efficiently to manage many connections between STBs(terminal) and return channel system for interactions of many users, to handle multiple Java applications for dispersion and to create easily the various services like Web services. As a result of that, this becomes to mature as well as Web system, which has been stable, verified and powerful technology. And if it is developed by using Web technologies, it is possible to establish interactive return channel system shortly. WRCS is composed of three style servers The first, the Web servers maintain session control management with HTTP and TCP/IP protocols and TLS with SEED algorithm based on A/96, ACAP standard. Secondly, application servers support to work on real Java or HTML interactive applications according to broadcasting schedules. Thirdly, database servers work to storage mainly for offering the information of broadcast terminal, user, broadcast schedules, and so on. One of the distinguishing features of the WRCS is the developed technology provided by EJB platform for reusing.
