Apple TV in Learning Mode

In Apple's patent FIG. 1 we see a media processing device 105 (Apple TV) which could be configured to detect command signals transmitted by a plurality of secondary controllers, such as the secondary controller 145. A secondary controller could be a controller associated with another device provided by the same manufacturer or a third-party controller.

Apple TV could be configured to identify the protocol used by the secondary controller to transmit the command signals. For example, Apple TV could be configured to generate a signature representing a received command signal. The signature format could be structured to accommodate a plurality of different transmission protocols. Further, the signature could be analyzed using matching heuristics to identify the protocol used to transmit the command signal. Once the transmission protocol has been identified, the command signal can be interpreted in accordance with the identified protocol to extract the message being communicated. The extracted message could be encoded in digital form and processed by Apple TV.

Apple TV could operate in a learning mode, in which command signals transmitted by a remote control device are captured and mapped to a corresponding function. For example, in learning mode, Apple TV could instruct a user to actuate a control on the remote control device being learned that corresponds to a particular function. Apple TV could capture and buffer the command signal received by the sensor for a predetermined period of time, such as 2 seconds. The buffered command signal could then be analyzed to identify one or more characteristics. For example, Apple TV could determine whether the buffered command signal was consistent for the entire period of time and whether the signal includes an initial message and one or more repeat messages. Further, one or more timing characteristics of the buffered command signal could also be analyzed, such as the maximum time between events. Apple TV could then store the identified characteristics for use in identifying command signals while in command interpretation mode.

Learn Remote

The remote control interface 200 shown below could also include options associated with one or more secondary remote controllers. For example, the remote control interface could include a learn remote option 210, which could be accessed to permit Apple TV to learn command signals associated with an additional controller, such as the secondary controller 145. Further, the remote control interface could include options to access stored profiles corresponding to secondary remote controllers, such as the TV remote 215 and the Custom remote 220. A stored profile could be accessed to perform one or more management tasks with respect to that profile. For example, a stored profile could be accessed to perform functions such as renaming the profile, deleting the profile, or modifying the profile by remapping one or more commands.

Apple TV: iPhone Simulation

A very interesting point that is clearly visible in FIG. 2 above isn't highlighted in the patent verbiage whatsoever. Under "Pair Apple Remote" in FIG. 2 we see iPhone Simulator. While the iPhone and an iPod touch could become remote controllers for Apple TV, what is an iPhone Simulator? Well, Apple discussed this in an August 2009 patent application. It was my hunch at that time that iPhone simulation would go far beyond being a tool for developers and become a means of being a simulated on-screen iPhone for consumer devices such as the iMac. In this case, the iPhone simulation could be presented on an HDTV. This marketing twist could be very powerful for Apple in the consumer space if Apple TV would ever go beyond the hobby phase at Apple.

 
Apple's patent FIG. 4 shows a basic button interface 400 presented by Apple TV. The basic button interface could be presented in response to input accessing the start option 305 of the "learn remote" interface 300. The basic button interface includes instructions (405) indicating which control is to be actuated on the secondary controller being learned, such as the secondary controller 145. For example, if the UP navigation button is being mapped to a corresponding command-signal, the message "Press and hold the Up button on the other remote. Continue to hold the Up button until the progress bar is full" could be displayed. However, any control can be designated as the Up button. For example, if the secondary controller doesn't include an Up button, a different control that will not be mapped to any other media processing device 105 function could be designated. In some implementations, an audio instruction can be presented in conjunction with or in place of the on-screen instructions 405.

Apple's patent FIG. 6 shows a flow diagram describing an exemplary process for detecting and learning command signals

Protocol and Head Pulse Tables

Apple's patent FIG. 10: A table 1000 includes a series of entries for a variety of different protocols. For each protocol, a pulse count is provided in one column along with an indication if phase encoding is implemented (in a second column). As represented in the table 1000, some of the protocols have multiple pulse counts that are acceptable, to indicate commands of different lengths. When scoring PDE protocols, if the pulse count of the IR signature matches any of the multiple pulse counts that are acceptable, the protocol is given a matching score.

Apple's patent FIG. 11: A table 1100 provides head pulse width ranges and header space width ranges that could be utilized by the remove-control driver 700 for comparing with an IR signature and to score the corresponding listed protocols.

Apple credits Rainer Brodersen, Stephanie Cinereski and Jack Fu as the inventors of patent applications 20100123834 and 20100123598, originally filed in Q1 2009.
