ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an information processing apparatus and method and a distribution medium and particularly to an information processing apparatus and method and a distribution medium which can read and display the alternative data different from the data to be intrinsically displayed when the data read from a tag comprising a non-contact type memory cannot be displayed normally.
2. Description of Related Art
Recently, an information processing apparatus which is accessible to a tag comprising a non-contact type memory (hereinafter referred to only as tag) is spreading widely.
FIG. 10
illustrates a block diagram of an information processing apparatus of the related art which is accessible to tag. In
FIG. 10
, when a storage medium (video cassette, for example) on which a tag
102
is adhered is loaded or placed nearer in the predetermined distance to an information processing apparatus
101
, a read writer
111
reads data of the predetermined address (area) of the memory comprised in the tag
102
via an antenna
112
. The data read from the memory is then converted to the predetermined format by the read writer
111
and is then supplied to OSD (On Screen Display) section
113
. The OSD section
113
converts the data supplied from the read writer
111
to the data which can be displayed by the display section
114
.
FIG. 11
illustrates a data format of tag
102
. The address in the horizontal direction is structured by
16
bytes
8
from address
0
to address
15
). As shown in
FIG. 11
, data of tag
102
is structured by memory management information area
121
, media information area
122
and program information area
123
. Depending on the data area, character code is stored (for example, character code
124
of the program information area
123
) in order to designate the characters to be displayed on the display section
114
.
Moreover, a program title is written as the data suggesting recorded content in the predetermined area of the program information area
123
. This title is expressed, in the case of English, by the character code defined by one byte but expressed, in the case of Japanese, by the character code of defined by two bytes.
However, when the tag
102
for storing data expressed by the character code defined by two bytes (for example, Japanese) is loaded or placed nearer to the information processing apparatus of the related art supporting only the character code defined by one byte (for example, English), there rises a problem that the display section
114
does not display data or displays, if it is realized, quite different characters (illegal characters).
SUMMARY OF THE INVENTION
Considering such background, the present invention has been proposed. Namely, if the information processing apparatus cannot display the data read from a tag, it can display alternative data different from the data to be intrinsically displayed. Moreover, the information processing apparatus can display such situation. Moreover, the apparatus notifies the condition that display is impossible, using a warning sound.
An information processing apparatus according to a first embodiment of the invention corresponds to the information processing apparatus accessible to a non-contact type storage device comprising judging means for judging whether data being stored in the storage device can be displayed or not; reading means for reading alternative data from the storage device when the data is judged not to be displayed by the judging means; converting means for converting the alternative data read by the reading means to the data to be displayed; and display controlling means for making control to display the data converted by the converting means.
An information processing method according to a second embodiment of the invention corresponds to the information processing method of an information processing apparatus accessible to a non-contact type storage device, comprising judging step for judging whether data being stored in the storage device can be displayed or not; reading step for reading alternative data from the storage device when the data is judged not to be displayed in the judging step; converting step for converting the alternative data read in the reading step to the data to be displayed; and display controlling step for making control to display the data converted in the converting step.
A distribution medium according to the invention corresponds to the distribution medium providing a program for causing an information processing apparatus accessible to a non-contact type storage device to execute the processes including judging step for judging whether data being stored in the storage device can be displayed or not; reading step for reading alternative data from the storage device when the data is judged not to be displayed by the judging step; converting step for converting the alternative data read in the reading step to the data to be displayed; and display controlling step for making control to display the data converted in the converting step.
In the information processing apparatus of the first embodiment, the judging means judges whether data stored in the storage device can be displayed or not and the reading means reads, when the judging means judges that data cannot be displayed, the alternative data from the storage device, the converting means converts the alternative data read by the reading means to the data to be displayed and the display controlling means controls to display the data converted by the converting means.
In the information processing method of the second embodiment and the program provided on a distribution medium according to the invention, it is judged in the judging means that the data stored in the storage device can be displayed or not, alternative data is read in the reading step when it is judged that data cannot be displayed in the judging step, the alternative data read by the reading step is converted to the data to be displayed in the converting step and the data converted in the converting step is controlled to be displayed in the display controlling step.
