Patent ID: 8832844

Claim:
A method comprising: receiving data from a first device through a first multimedia interface having a first content protection scheme; receiving data from a second device through a second multimedia interface having a second content protection scheme, the first multimedia interface and the second multimedia interface using different interface formats with respect to each other; decoding the data received through the first multimedia interface and obtaining content protection signaling information for the first device; decrypting by a decryption module the decoded data received through the first multimedia interface using the content protection signaling information obtained for the first device; outputting the decrypted data received from the first device at an output port; decoding a portion of the data received through the second multimedia interface and obtaining content protection signaling information for the second device prior to the second multimedia input being designated for output, the content protection signaling information of the second device comprising content protection encryption status of the second device; receiving a port switching signal to cause data received by the second multimedia interface to be coupled to the output port and data received by the first multimedia interface to be decoupled from the output port; decrypting by the decryption module the decoded the portion of the data received through the second multimedia interface using the protection signal information obtained for the second device; and outputting the decrypted data received from the second device.
