چکیده
Today’s interactive television systems are using proprietary communication protocols and interchange formats. To provide interoperability at the application level the next generation of interactive television system will be based on standardized communication protocols, monomedia and multimedia formats. This paper presents the Globally Accessible Services (GLASS) system which is a prototype interactive television system based on the Multimedia and Hypermedia Expert Group (MHEG) standard. After a brief introduction to MHEG as the multimedia interchange format between application server and set-top box in interactive television systems, the GLASS clients and servers are described, and an example scenario for navigation in the GLASS system is provided.

متن کاملCooperative Use of MHEG and HyTime in Hypermedia Environments
The standards MHEG and HyTime are interchange formats for hypermedia information. While they may seem to compete, they actually can play separate and complementary roles in a complete and open hypermedia environment. MHEG is used for portable final-form hypermedia presentations. HyTime is used for the long-term, presentation-independent storage of hypermedia documents. Given these tasks, MHEG c...
