Abstract: An example first playback device is configured to (i) obtain audio content from a cloud-based media service, the audio content encrypted according to a first encryption scheme, (ii) communicate with a cloud-based license service to obtain information for decrypting the audio content, (iii) use the obtained information to decrypt the audio content, (iv) re-encrypt the decrypted audio content in accordance with a second encryption scheme, (v) transmit the re-encrypted audio content to at least a second playback device that is grouped with the first playback device for synchronous audio playback, and (vi) play back the audio content in synchrony with playback of the audio content by the second playback device.

Abstract: A playback device is configured to (i) transmit, via at least one wireless network interface and indication that the playback device is available for setup, (ii) establish a direct communication path with a computing device configured to operate on a secure wireless network, (iii) provide, outside the direct communication path, authentication information to the computing device, (iv) verify, via the direct communication path, the authentication information with the computing device, (v) after verifying the authentication information via the direct communication path, receive, from the computing device over the direct communication path, network configuration parameters for connecting to the secure wireless network, (vi) use the network configuration parameters to connect to the secure wireless network, and (vii) transition from communicating with the computing device over the direct communication path to communicating with the computing device over the secure wireless network.
