TTA (Secretary general Kim Hong-Koo) announced that a working group was established under the DMB project group (PG307 chaired by Professor Lee Sang-Woon, Yonsei University) and TTA would start standardization activities to develop a draft standard for the Traffic and Traveler Information Service based on the T-DMB and the middleware standards, which will be the basis of the interactive DMB broadcasting.

The Traffic and Traveler Information (TTI) service working group meeting, held on April 27, 2006, worked out the plan to standardize the Traffic and Traveler Information (TTI) service for T-DMB, and appointed Mr. Chae Yeong-Seok (KBS) as the working group's chairman. The TTA Steering Committee, held on March 29, accepted the draft TTI service standard submitted by the DMB subcommittee of the domestic next-generation broadcasting standard forum as a standardization project and decided that the DMB project group should carry out the standardization work. The Traffic and Traveler Information field, which many broadcasting service providers are interested, is a core application service of data broadcasting and a one of the top fee-charging model of DMB data broadcasting. This working group is planning to determine the scope of the standardization work on the basis of the draft standard submitted by the Next Generation Digital Broadcasting Standards Forum and will establish a number of draft standards including the T-DMB TTI service location referencing standard. Chairman Chae Yeong-Seok said that this draft standard which is to be established by the second half of this year will greatly contribute to the revitalization of DMB by using the broadcasting network to provide various types of information to navigators.

In addition, the DMB middleware service working group, which met on April 28, 2006, appointed Mr. Park Sang-Oh (LG Electronics) as its chairman and decided to establish the method of transmitting Java application through the DMB broadcasting network and the standard defining the environment for the DMB receiver capable of executing the transmitted Java applications. The middleware service standard defines the middleware specifications capable of providing more flexible data service with wider applicability than existing data services. The working group is going to discuss the common application program execution environment for both T-DMB and S-DMB, the API (Application Interface) for the application program execution environment, and extend it into a standard for links with supplementary services such as EPG (Electronic Program Guide) and PVR (Personal Video Recorder). If this standard is completed, as Chairman Park Sang-Oh predicts, the Java application programs transmitted by broadcasting service providers will be downloaded to the receiver through the broadcasting network and as the application programs are executed on the DMB receiver, diverse data broadcasting services such as e-commerce, games, weather and news, will be possible. Therefore, data services with wider applicability and far more dynamic than previous data services will be available, and hence, greatly contributing to the expansion of the DMB service.
