Abstract

There is provided a contents display apparatus capable of receiving signage data including contents from a contents management apparatus, the contents display apparatus including: an alternative contents storage unit which receives alternative contents from the contents management apparatus and stores the alternative contents; an acknowledgement unit which causes the contents management apparatus to acknowledge validity of the signage data; and a contents display unit which displays contents based on the signage data in a case where the validity of the signage data is acknowledged by the acknowledgement unit and displays the alternative contents in other cases.

First claim

What is claimed is:

1. A contents display apparatus that receives signage data including contents from a contents management apparatus, the contents display apparatus comprising:
an alternative contents storage that receives alternative contents from the contents management apparatus and stores the alternative contents;
acknowledgement circuitry that causes the contents management apparatus to acknowledge validity of the signage data; and
a contents display that displays contents based on the signage data, wherein
the acknowledgement circuitry:
generates validity acknowledgement information from the signage data,
transmits a validity acknowledgement request signal including the validity acknowledgement information to the contents management apparatus to cause the contents management apparatus to acknowledge the validity of the signage data, and
receives a validity acknowledgement response signal including an acknowledgement result of the validity from the contents management apparatus, and

the contents display displays contents of the signage data in a case where the validity acknowledgement response signal received by the acknowledgement circuitry indicates the validity of the signage data and displays the alternative contents stored in the alternative contents storage in other cases.

2. The contents display apparatus according to claim 1 , wherein the validity acknowledgement information is one of a hash value, a data size, or a time stamp of the signage data.

3. The contents display apparatus according to claim 1 , wherein the signage data includes contents data and a contents display schedule.

4. The contents display apparatus according to claim 3 , wherein the contents display schedule is set to prescribed time zones and one or a plurality of the contents are included in each of the set time zones.

5. The contents display apparatus according to claim 1 , wherein the acknowledgement circuitry causes the contents management apparatus to acknowledge the validity of the signage data at a validity acknowledgement time determined in advance.

6. The contents display apparatus according to claim 5 , wherein the validity acknowledgement time is set to a point of time when a prescribed time interval elapses.

7. The contents display apparatus according to claim 1 , wherein the acknowledgement circuitry causes the contents management apparatus to acknowledge the validity of the signage data immediately before the content is displayed.

8. The contents display apparatus according to claim 4 , wherein the acknowledgement circuitry causes the contents management apparatus to acknowledge the validity of the signage data immediately before the time zone.

9. The contents display apparatus according to claim 1 , further comprising:
a signage data storage that stores the signage data received from the contents management apparatus, wherein the signage data is stored in a region different from a region in which the alternative contents are stored.

10. A contents display method of a contents display apparatus that receives signage data including contents from a contents management apparatus, the contents display method comprising:
receiving alternative contents from the contents management apparatus and storing the alternative contents;
generating validity acknowledgement information from the signage data;
transmitting a validity acknowledgement request signal including the validity acknowledgement information to the contents management apparatus to cause the contents management apparatus to acknowledge validity of the signage data;
receiving a validity acknowledgement response signal including an acknowledgement result of the validity acknowledged by the contents management apparatus; and
displaying contents of the signage data in a case where the validity acknowledgement response signal received by acknowledgement circuitry indicates the validity of the signage data and displaying the alternative contents stored in an alternative contents storage in other cases.

11. A contents display system that includes a contents display apparatus that receives signage data including contents from a contents management apparatus, wherein the contents display apparatus:
receives alternative contents from the contents management apparatus and stores the alternative contents;
generates validity acknowledgement information from the signage data;
transmits a validity acknowledgement request signal including the validity acknowledgement information to the contents management apparatus to cause the contents management apparatus to acknowledge validity of the signage data;
receives a validity acknowledgement response signal including an acknowledgement result of the validity acknowledged by the contents management apparatus; and
displays contents of the signage data in a case where the validity acknowledgement response signal received by acknowledgement circuitry indicates the validity of the signage data and displays the alternative contents in other cases.
