The object of the present invention can be achieved by
providing a record displaying apparatus comprising: a user
that the user designates respective recording time and channel

Recently, in addition to the spread of digital broadcast

receivers, a digital broadcast receiver DVR including a stor
age medium to record/reproduce digital broadcast data has
been developed.
As the digital broadcasting is regularized, it is expected
that such a DVR Will rapidly substitute existing video cassette

equipped With a high-performance central processing unit

easily retrieve a desired one of the stored programs, and to

The digital broadcast receiver DVR also provides an EPG

user. The EPG may be considered to be similar to a table

Exceptionally, When a neW record is registered to the

In accordance With the above-described method, the

The thumbnail image creating method can be divided into
a method in Which a frame of a video encoded in an MPEG
scheme is decoded, and the decoded frame is directly reduced
in siZe, and a method in Which the DC value of an I-picture is
used. In the former case, it is necessary to decode all pixels of
the frame. For this reason, a variable-length decoder is
needed.
In the latter case, no variable-length decoder is needed
because a thumbnail image is created using the DC value of
an I-picture. The latter method is also simple.
