Embodiment Construction

[0010] now refer to Figure 1A , which illustrates an exemplary home entertainment system in which audio and / or The video outputs are both connected to the audio and / or video inputs of the AV receiver 100 . The AV receiver 100 plays the function of switching the specified audio and / or video output of the currently desired input media stream to the AV receiver 100, and the currently desired input media stream is controlled by one or more audio and / or video outputs of the AV receiver. For video input reception, the AV receiver 100 is connected to an output capable device such as a television 110 . In some implementations, the AV receiver 100 may also include a wired or wireless network interface, which may be used for routing of media, such as streaming media from or to other areas of the home wirelessly over the WiFi connection 114 . When included, a network interface may also be used for Internet access 116, downloading firmware updates and / or other data into the AV receiver...

Abstract

A first controllable device receives a command from a second controllable device to place the first controllable device in a state, and in response determines a trust level for the second controllable device. When it is determined that the second controllable device is trustworthy, the first controllable device executes the command. When it is determined that the second controllable device is not trustworthy, the first controllable device ignores the command. Otherwise, the first controllable device enters a state where the first controllable device waits for at least a predetermined period of time for the user to confirm whether the first controllable device should execute the command.

Description

Background technique [0001] Interconnections between user devices such as televisions, set-top boxes for receiving and decoding cable and satellite signals, AV receivers, DVD players, gaming systems, streaming media adapters, etc. ) in the form of a standard digital interface. In addition to supporting high-quality audio / video signals, this digital interconnection facilitates the exchange of commands, identity information, and data capacity between devices. In particular, devices that support a feature known as Consumer Electronics Control (CEC) can be commanded and controlled over an HDMI connection without user intervention when engaged via an HDMI connection. In those systems where HDMI-connected devices support the CEC function, this function allows one button to control various functions such as power-on of the entire system. However, while generally useful, if one or more source devices in the HDMI interconnection system is not functioning properly and commands devices...
