  Here, the relationship of each metadata in the advertisement insertion type video distribution system of this embodiment will be described in detail based on FIG.

  The content provider creates content information D1a from information related to the content (for example, content ID, content provider ID, etc.). The content ID Cid (for example, “06ab37”) is set to be unique for the content to be handled.

  The corner metadata information D1b related to the content information D1a is created from information related to the corner (for example, content ID, corner ID, genre). Note that the same value (eg, “06ab37”) as the content ID Cid of the content information D1a is set in the corner metadata information D1b. Further, in order to divide the segments t1 to t3 of the corner metadata information D1b, for example, the time from the top of the content and the number of frames are set. For the segment, the time of the segment itself and the number of frames included in the segment may be set.

  Then, the insertion point information D1c corresponding to the corner metadata information D1b is created. First, the content ID Cid of the insertion point information D1c sets the value of the content ID Cid of the content information D1a. In the insertion point position ISt, a desired segment value (or segment number) is set from the segments t1 to t3. The insertion point ID ISd inputs data (for example, combined data) based on the content ID Cid, the content provider ID CPid, and the insertion point insertion position ISt to the hash function, and the output value (hash value) of the hash function ) Is created with an encryption key held by the content provider (for example, a private key in a public key cryptosystem), and the electronic signature is set in the insertion point ID ISd.
