Abstract
A system is disclosed wherein a content is distributed without using a network. The distributed content is acquired and reproduced by a content acquisition apparatus.
Claims19
A content distribution system, comprising:
- a content providing medium having a hologram memory in which content data is recorded as distribution data;
- and
- an acquisition apparatus for reading out and acquiring the distribution data from said hologram memory provided on said content providing medium.
A content providing medium production method, comprising the steps of:
- converting content data into hologram master data;
- producing a master recording medium using the hologram master data;
- and
- producing providing medium, for duplicating a hologram memory from the master recording medium and providing a predetermined content providing medium with the fabricated hologram memory.
A content acquisition apparatus for acquiring content data from a content providing medium having a hologram memory in which the content data is recorded as distribution data, comprising:
- reference light outputting means for outputting reading out reference light to said hologram memory on the content recording medium;
- detection means for detecting, in a state wherein the reading out reference light is applied to said hologram memory by said reference light outputting means, a reproduction image based on data recorded in said hologram memory;
- and
- reproduction processing means for reproducing a data string as the content data from the reproduction image detected by said detection means.
A content acquisition method for acquiring content data from a content providing medium having a hologram memory in which the content data is recorded as distribution data, comprising the steps of:
- detecting, in a state wherein reading out reference light is applied to said hologram memory on said content providing medium, a reproduction image of data recorded in said hologram memory;
- and
- reproducing a data string as the content data from the reproduction image detected at the detection step.
A content acquisition apparatus for acquiring content data from a content providing medium having a hologram memory in which the content data is recorded as distribution data, comprising:
- a reference light outputting section for outputting reading out reference light to said hologram memory on the content recording medium;
- a detection section for detecting, in a state wherein the reading out reference light is applied to said hologram memory by said reference light outputting section, a reproduction image based on data recorded in said hologram memory;
- and
- a reproduction processing section for reproducing a data string as the content data from the reproduction image detected by said detection section.
