Abstract
Methods and apparatus are disclosed for supplementing partially readable and/or inaccurate codes. An example apparatus includes a watermark analyzer to select a first watermark and a second watermark decoded from media; a comparator to compare a first decoded timestamp of the first watermark to a second decoded timestamp of the second watermark; and a timestamp adjuster to adjust the second decoded timestamp based on the first decoded timestamp of the second watermark when at least a threshold number of symbols of the second decoded timestamp match corresponding symbols of the first decoded timestamp.
Claims20
A computing system configured to perform a set of operations, the set of operations comprising:
- obtaining data indicative of a first watermark and a second watermark decoded by a decoder, wherein the first watermark and the second watermark are encoded in media presented by a media presentation device, wherein the data comprises:
- a complete timestamp value decoded from a payload of the first watermark,
- a decoding time of the first watermark,
- a partial timestamp value decoded from a payload of the second watermark, and
- a decoding time of the second watermark;
- determining an adjusted timestamp value to associate with the second watermark based on the decoding time of the first watermark, the decoding time of the second watermark, and the complete timestamp value;
- and
- associating the adjusted timestamp value with the second watermark.
A method comprising:
- obtaining, by a computing system, data indicative of a first watermark and a second watermark decoded by a decoder, wherein the first watermark and the second watermark are encoded in media presented by a media presentation device, wherein the data comprises:
- a complete timestamp value decoded from a payload of the first watermark,
- a decoding time of the first watermark,
- a partial timestamp value decoded from a payload of the second watermark, and
- a decoding time of the second watermark;
- determining an adjusted timestamp value to associate with the second watermark based on the decoding time of the first watermark, the decoding time of the second watermark, and the complete timestamp value;
- and
- associating the adjusted timestamp value with the second watermark.
A non-transitory computer-readable medium having stored therein instructions that, when executed by a computing system, cause the computing system to perform a set of operations comprising:
- obtaining data indicative of a first watermark and a second watermark decoded by a decoder, wherein the first watermark and the second watermark are encoded in media presented by a media presentation device, wherein the data comprises:
- a complete timestamp value decoded from a payload of the first watermark,
- a decoding time of the first watermark,
- a partial timestamp value decoded from a payload of the second watermark, and
- a decoding time of the second watermark;
- determining an adjusted timestamp value to associate with the second watermark based on the decoding time of the first watermark, the decoding time of the second watermark, and the complete timestamp value;
- and
- associating the adjusted timestamp value with the second watermark.
