Abstract
A media client device, including a memory and capable of processing Quadrature Amplitude Modulation (QAM) channels and IP channels, may receive a recording request to record content on an Internet Protocol (IP) channel. The media client device may provide, to a first device, a source Universal Resource Locator (URL) corresponding to the content, and receive, from the first device, encrypted content (e.g., an encrypted version of the content). The media client device may store, in the memory, the encrypted content, and provide, to a second device, information regarding the encrypted content to permit the second device to generate and store a license and a key. The media client device may receive a playback request to play the content, and obtain, from the second device, the license and the key. The media client device may decrypt, using the license and the key, the stored, encrypted content to obtain the content.
