Product variations and testing

Many variations are possible in a product that includes Dolby Digital Plus technology.

For a product that supports several variations, you may need to run a test case repeatedly to cover every variation. For example, if your product supports playback of both unencrypted and encrypted content, you must run each test case with encrypted and unencrypted content.

The Dolby Digital Plus Online Delivery System Interactive Test Procedure adapts to product variations and presents applicable tests only based on various factors. The Dolby System Interactive Test Procedure uses the form of a questionnaire to request information about which factors are supported by a product, and then uses this information to provide test instructions for all applicable test cases. Unless otherwise stated in the individual test instructions, running each test case for each supported variation is generally recommended.

Factors influencing product variations are described in this section.
