  • the processor could recognize the recording profile by its file extension and then use the video content recording parameters specified in that file to record video content on that memory device. In this way, a user can insert a memory device into his or another's video content recording apparatus, and the apparatus would know how to record the video content consistent with the user's playback device without requiring any further action by the user.
  • the video content recording apparatus would automatically record video content for a particular playback device without a user having to manually select a target playback device. More generally, the video content recording apparatus can be configured to (1) always let the recording profile override previous settings, (2) never let the recording profile override previous settings, or (3) let the recording profile override previous settings after confirmation by the user. In the event that the recording profile is used, the video content recording apparatus can be configured to return to its previous video content recording parameters after the removable memory device is removed from the apparatus.
  • circuitry can take the form of a processor executing computer-readable program code stored in a computer-readable medium (e.g., here, firmware stored in embedded memory).

  • computer-readable media other than embedded memory such as, but not limited to, a hard drive, a removable memory device, etc. can be used to store computer-readable program code.
  • firmware can be software routines stored in embedded memory or in a storage device other than embedded memory.
  • Circuitry can take other suitable forms, such as an application specific integrated circuit (ASIC), a programmable logic controller, an embedded microcontroller, and a single-board computer. Accordingly, the term “circuitry” should not be limited to any particular type of implementation, described herein or otherwise. Further, “circuitry” should not be limited to the functions described herein. For example, when circuitry takes the form of a processor executing firmware, as above, it should be understood that the processor can perform functions in addition to the ones described above.
