CIMM DEFINITION:  An encrypted, unique persistent, anonymous code (such as an encrypted MAC ID) to identify different Viewing Devices when calculating unique viewer metrics. (Source: CTAM Advanced Cable Solutions Consortium, DAI Metrics)

NOTE – A Viewing Device that is returned and re-deployed to another household should be considered as a new Viewing Device when calculating unique user metrics. The methodology for generating a Unique Viewing Device ID is subject to compliance with MVPD privacy policies. Future methodologies for ensuring uniqueness across MVPDs (i.e. no two Viewing Device IDs are the same) need to be developed. (Source: CTAM Advanced Cable Solutions Consortium, DAI Metrics)
