Abstract
A method of processing remote control commands at a control device consistent with certain embodiments involves at the control device, receiving commands directed to the control device; at the control device, receiving a command directed to a source device, the source device being operative to provide video content to a display; and at the control device, interpreting the command directed to the source device in order to track a state of operation of the source device. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
Claims34
A method of processing remote control commands at a control device, comprising:
- at the control device, receiving commands directed to the control device;
- at the control device, receiving a command directed to a source device, the source device being operative to provide video content to a display;
- at the control device, interpreting the command directed to the source device in order to track a state of operation of the source device;
- and
- at the control device, carrying out an optical character recognition (OCR) process on video content produced by the source device, where the OCR process is enabled to detect special symbols in the video frames.
A method of processing remote control commands at a control device, comprising:
- at the control device, receiving commands directed to the control device;
- at the control device, receiving a command directed to a source device that determines that the source device is to enter a state of inactivity, the source device being operative to provide video content to a display;
- at the control device, interpreting the command directed to the source device such that the source device is being instructed to enter the state of inactivity;
- at the control device, determining that no command has been received within an established time period that changes a source of video to the display to a source of content other than the source device;
- and
- as a result of the determining, placing the display into an energy conserving standby state.
A method of processing remote control commands at a digital television, comprising:
- at the digital television, receiving commands directed to the digital television;
- at the digital television, receiving a command directed to a source device that determines that the source device is to enter a state of inactivity, the source device being operative to provide video content to the digital television;
- at the digital television, interpreting the command directed to the source device such that the source device is being instructed to enter the state of inactivity;
- at the digital television, determining that no command has been received within an established time period that changes a source of video to the digital television to a source other than the source device;
- and
- as a result of the determining, placing the digital television into an energy conserving standby state.
A method of processing remote control commands at a control device, comprising:
- at the control device, receiving a sequence of commands directed to the control device, where the sequence of commands comprise a selection command preceded by a sequence of navigation commands;
- at the control device, receiving a command directed to a source device, the source device being operative to provide video content to a display;
- at the control device, interpreting the command directed to the source device in order to track a state of operation of the source device, where the interpreting is carried out by optical character recognition (OCR) processing a frame of video corresponding to a menu in order to determine that the sequence of navigation commands leads to a selection command that causes the source device to enter a known state of operation or inactivity;
- and
- at the control device, carrying out an optical character recognition (OCR) process on video content produced by the source device.
