Methods and apparatus for managing interfaces in a placeshifting device
First Claim
1. A placeshifting device configured to receive media content from a media source, the placeshifting device comprising:
- a controller having a placeshifting mode; and
a first receiver interface coupled to the controller and the media source, the first receiver interface having a selectable copy-protection capability;
wherein the controller is configured to;
disable the copy-protection capability of the first receiver interface when the processor enters a placeshifting mode,determine that the media source implements selectable output control;
determine whether a second receiver interface is coupled to the media source via the selectable output control; and
disable the first interface if the second receiver interface is coupled to the media source.

Abstract
A placeshifting device handles content from a media source (e.g., a set-top box) that might incorporate a form of copy-protection such as HDCP. In one case, when a placeshifting mode is entered (as opposed to a pass-through mode), the copy-protection capability of the interface (e.g., an HDMI interface) is simply disabled. In another case in which the media source includes a copy protection “flag” or the like that can be interrogated by the placeshifting device, the placeshifting device determines whether the media source copy-protection is enabled, and only then disables the copy-protection capability of the interface. In another case in which selectable output control (SOC) is available in the media source, the placeshifting device determines whether alternate interfaces are available (e.g., component video, composite video, and the like), and if so, disables the interface having copy-protection capability.

7. A method for managing an interface between a placeshifting device and a media source, comprising:
-
determining whether the placeshifting device is in a pass-through mode or a placeshifting mode; disabling a copy-protection capability of the interface when the placeshifting device enters the placeshifting mode; enabling the copy-protection capability of the interface when the placeshifting device enters the pass-through mode; determining that the media source implements selectable output control; determining whether a second receiver interface is coupled to the media source via the selectable output control; and disabling the first interface if the second receiver interface is coupled to the media source. - View Dependent Claims (8, 9, 10, 11, 12)

13. Non-transitory computer-readable media bearing software instructions configured to instruct a processor to:
-
determine whether a placeshifting device is in a pass-through mode or a placeshifting mode; disable a copy-protection capability of an interface between the placeshifting device and a media source when the placeshifting device enters the placeshifting mode; and enable the copy-protection capability of the interface when the placeshifting device enters the pass-through mode; determine that the media source implements selectable output control; and determine whether a second receiver interface is coupled to the media source via the selectable output control; and disable the first interface if the second receiver interface is coupled to the media source. - View Dependent Claims (14, 15, 16, 17)
