to implement PlayReady license acquisition and key exchange on a protected content playback app. - A developer who wishes to implement PlayReady license acquisition and key exchange on a protected content playback app would first need to ensure that their app meets all of the necessary requirements for supporting PlayReady. These requirements are outlined in the PlayReady Compliance and Robustness Rules document. Once the developer has ensured that their app meets all of the required rules, they can then proceed with implementing the license acquisition and key exchange process. - The first step in this process is for the developer to generate a unique request ID for each individual user who will be requesting a license. This request ID must be included in every call made to the PlayReady License Server (PRLS) when acquiring or renewing a license. The developer must also include several other pieces of information in these calls, such as the type of content being requested (e.g., video, audio, etc.), the user’s device ID, and an identifier for the specific rights that are being requested. - Once all of this information has been properly generated and collected, the developer can then make a call to PRLS in order to acquire a license for their content. If successful, PRLS will return a signed XML document containing variousPlayReady-specific data points, including a licensing token which will be used by the client device during content decryption. The developer must then parse this XML document in order to extract the necessary information before finally passing it along to their app’s end users.
