发明名称 METHODS AND APPARATUS TO IDENTIFY MEDIA USING HASH KEYS
摘要 Methods and apparatus are disclosed to correct hash keys. An example method involves accessing a first metered hash key and first reference metadata associated with the first metered hash key. Accessing second reference metadata associated with a second hash key adjacent to the first metered hash key. Determining if the first metered hash key is unexpected. When the first metered hash key is unexpected, generating an error level using a first bitwise comparison of the first metered hash key and the second hash key. Determining if the error level satisfies a threshold. When the error level satisfies the threshold, storing the second hash key as the first metered hash key.

主权项 1. A method comprising: accessing, by executing an instruction with a processor, a first metered hash key and first reference metadata associated with the first metered hash key; accessing, by executing an instruction with the processor, second reference metadata associated with a second hash key adjacent to the first metered hash key; determining, by executing an instruction with the processor, if the first metered hash key is unexpected; when the first metered hash key is unexpected, generating, by executing an instruction with the processor, an error level using a first bitwise comparison of the first metered hash key and the second hash key; determining, by executing an instruction with the processor, if the error level satisfies a threshold; and when the processor determines that the error level satisfies the threshold: storing, by executing an instruction with the processor, the second hash key as the first metered hash key.
