Receiving device, signaling device, and method for receiving recovery file information
A system for retrieving watermark associated recovery data information.
1. A receiving device for receiving recovery file information, the receiving device comprising:
a processor, and
a memory associated with the processor; wherein
the processor is configured to:
receive a recovery data table, wherein the recovery data table includes a contentID element identifying a content identifier and having a cardinality of 0 . . . . N,
wherein the contentID element includes:
(i) a type element, wherein
the type element is defined by two values, which include (a) a first value indicating a content identification per an EIDR registry and (b) a second value indicating a content identifier per an Ad-ID registry, and
additional types for user private content identifiers may be used by setting the type element to a third value, and
(ii) a cid element, wherein
the cid element is a 34-character canonical form with hyphens in a case of an EIDR content ID system,
the cid element is 11-character or 12-character form or ASCII characters representing a decimal value of a 4-byte unsigned integer Compact Ad-ID Identifier in a case of an Ad-ID Content ID system, and
decode the cid element of the recovery data table.
2. A signaling device for signaling recovery file information, the signaling device comprising:
a processor, and
a memory associated with the processor; wherein
the processor is configured to:
encode a recovery data table,
wherein the recovery data table includes a contentID element identifying a content identifier and having a cardinality of 0 . . . . N,
wherein the contentID element includes:
(i) a type element, wherein
the type element is defined by two values, which include (a) a first value indicating a content identification per an EIDR registry and (b) a second value indicating a content identifier per an Ad-ID registry, and
additional types for user private content identifiers may be used by setting the type element to a third value, and
(ii) a cid element, wherein
the cid element is a 34-character canonical form with hyphens in a case of an EIDR content ID system, and
the cid element is 11-character or 12-character form or ASCII characters representing a decimal value of a 4-byte unsigned integer Compact Ad-ID Identifier in a case of an Ad-ID Content ID system.
3. A method for receiving recovery file information, the method including:
receiving a recovery data table, wherein the recovery data table includes a contentID element identifying a content identifier and having a cardinality of 0 . . . . N,
wherein the contentID element includes:
(i) a type element, wherein
the type element is defined by two values, which include (a) a first value indicating a content identification per an EIDR registry and (b) a second value indicating a content identifier per an Ad-ID registry, and
additional types for user private content identifiers may be used by setting the type element to a third value, and
(ii) a cid element, wherein
the cid element is a 34-character canonical form with hyphens in a case of an EIDR content ID system, and
the cid element is 11-character or 12-character form or ASCII characters representing a decimal value of a 4-byte unsigned integer Compact Ad-ID Identifier in a case of an Ad-ID Content ID system,; and
decoding the cid element of the recovery data table.
