Interactive television (ITV) is a new type of consumer
video service that gives audiences more control over the TV
programs than is possible with tranditional televsion.
Traditional TV programs are presented in a linear, ordered
and single-direction manner. The audience can just watch the
television programs which are arranged by the content/
service provider. With an ITV program, audiences can directly
control what he or she is watch- ing. In order to aid a producer
to produce an interactive tele- vision program, there should be
an intergrated authoring tool. Approaches of existing
authoring tools include screen-based, time-line and script
based approach. The screen-based approach is lack of
portability. The script-based approach is not an user friendly
approach. The goal of this thesis is to propose a portable
and user-friendly authoring tool and environment to develop
ITV programs. In this thesis, besides analyzing the
requirement for one authoring of ITV programs, we also present
a hypermedia data model for hypermedia presentation of ITV
programs. We provide a portable and user-friendly authoring
tool. We define a script language to describe ITV programs and
implement the authoring tool
