I don't like to think apple would bow this deeply to the recording industry. Maybe the government. Either way it turns my stomach.
"At block 950, a record function can be disabled. For example, if the encoded data includes a disable command, the device can temporarily disable its record function for a period of time after receiving the command (e.g., 30 seconds or 30 minutes). After the device's record function is disabled, the device may not be able to store images detected by the device. In some embodiments, after the device's record function is disabled, the device may not be able to even display images detected by the device (see, e.g., system 500 shown in FIG. 5). In some embodiments, a device may even delete one or more of the most recently stored images (e.g., the first image detected at block 910) when disabling the device's record function."
