Abstract
An audio/video (AV) receiver is adapted to be dynamically reconfigured in a selected one of an encrypted content support mode and an unencrypted content support mode. The AV receiver includes a controller configured to dynamically alter one or more encryption settings based at least in part on user input provided to a mode toggle mechanism. The one or more altered encryption settings are effective to facilitate presentation of unencrypted content within a received media stream on a display while selectively preventing presentation of encrypted content included in the received media stream on the display.
Claims20
A system comprising:
- an audio/video (AV) sink device including:
- a mode toggle mechanism configured to receive user input for dynamically selecting between an encrypted content support mode and an unencrypted content support mode;
- and
- a controller configured to:
- dynamically alter one or more encryption settings of an AV sink device to transition the AV sink device between the unencrypted content support mode and the encrypted content support mode based at least in part on receiving the user input and without rebooting the AV sink device;
- detect encrypted content within a received media stream while the AV sink device is operating in the unencrypted content support mode;
- and
- based at least in part upon the detection of the encrypted content received while the AV sink is operating in the unencrypted content support mode, selectively prevent presentation of the encrypted content included in the received media stream on a display.
A method comprising:
- receiving user input indicating a selection of one of an encrypted content support mode and an unencrypted content support mode;
- and
- dynamically altering one or more encryption settings of an AV sink device to transition the AV sink device between the unencrypted content support mode and the encrypted content support mode based at least in part on receiving the user input and without rebooting the AV sink device;
- detecting encrypted content within a received media stream while the AV sink device is operating in the unencrypted content support mode;
- and
- based at least in part upon the detection of the encrypted content received while the AV sink is operating in the unencrypted content support mode, selectively preventing presentation of the encrypted content included in the received media stream on a display.
One or more tangible computer-readable storage media encoding computer-executable instructions for executing a computer process comprising:
- receiving a user input indicating a selection of one of an encrypted content support mode and an unencrypted content support mode;
- and
- dynamically altering one or more encryption settings of an AV sink device to transition the AV sink device between the unencrypted content support mode and the encrypted content support mode based at least in part on receiving the user input and without rebooting the AV sink device;
- detecting encrypted content within a received media stream while the AV sink device is operating in the unencrypted content support mode;
- and
- based at least in part upon the detection of the encrypted content received while the AV sink is operating in the unencrypted content support mode, selectively preventing presentation of the encrypted content included in the received media stream on a display.
