Abstract
Due to multichannel broadcasting, much contents consecutive in means
of time are being offered. Much of these contents require real-time
characteristics.
In existing methods for viewing two simultaneous TV programs, there
are several issues. For channel switching and displaying two programs
on one display simultaneously, since the user misses parts of the
program, the comprehension level decreases.
In this paper we focus on raising the comprehension
of two simultaneous TV programs. We therefore propose a crossover
viewing support method using time compressed playout. In this method
two TV programs are first buffered in real-time and the buffered
contents are alternately played out in a time compressed fashion.
Since the TV program may be switched in the middle of a statement,
comprehension may become challenging. Overlapped restart playout is
therefore introduced to alternate playout. This makes semi-real-time
viewing of two simultaneous TV programs possible. Through evaluation
experiments we showed that the proposed method raises the
comprehension level compared to existing methods.
