On Thursday, the United States Patent and Trademark Office published five new Apple patents under the titles “Methods and apparatuses for pixel transformations, Interface for defining aperture”, “Power management in a portable media delivery system”, “Dynamic power management in a portable media delivery system” and “Media delivery system with improved interaction.”
According to MacNN, the final three patents focus on Wi-Fi functionality in an iPod. Such a feature has been anticipated for some time and may come to light with the new iPods due out on September 5th.
Patent details are as follows:
“iPod Wi-Fi: Power management in a portable media delivery system”
Apple’s Abstract: A consumer electronic product that includes a media player arranged to process a selected one of a plurality of digital media files stored therein and a media delivery accessory unit detachedly connected to the media player arranged to broadcast the processed digital media file. When the consumer electronic product is in a DC mode, the consumer electronic product controls a transfer of an amount of charge between the media delivery accessory and the media player. In one embodiment, the amount of charge is sufficient to for the consumer electronic product to operate for a predetermined amount of time. In another embodiment, the amount of charge is sufficient for to maximize an amount of time that the media player and media delivery accessory can operate.
Apple lists Jesse L. Dorogusker, Donald J. Novotney, Scott Krueger and Jeffrey J. Terlizzi as the inventors of the patent. Apple also filed a related patent application titled Dynamic power management in a portable media delivery system
The third patent relating to Wi-Fi technology in an iPod discusses the ability to transmit equalizer instructions to the iPod. The inventors credited here include Jesse L. Dorogusker, Donald J. Novotney, Scott Krueger, Jeff Hammerstrom, Greg Marriott and Greg Lydon.
For the “Interface for defining aperture” patent, Apple describes a means of creating and storing data describing a pixel aspect ration and specification of the clean aperture of video data. The data can define parameters of one of more display modes and then selected for an individual track based upon rendering intent, storing the video data with these defined parameters in the process.
The patent credits Timothy David Cherna, John Samuel Bushell and Sean Matthew Gies as the inventors.
For the final patent, “Methods and apparatuses for pixel transformations”, the abstract is as follows:
Apple’s patent application relates to data processing systems and methods for processing pixel data, such as pixel format transformations. Apple’s Abstract goes on to state that the patent covers. РMethods, apparatuses, systems, and machine readable media for pixel transformations. One exemplary method includes: determining a state of a pixel format transformation, wherein a pixel format includes a predetermined number of pixel data components and a predetermined number of bits for each of the pixel data components and wherein the state includes a source pixel format and a destination pixel format and at least one intermediate pixel format; converting pixel data in the source pixel format to pixel data in the intermediate pixel format; and converting the pixel data in the intermediate pixel format to pixel data in the destination pixel format. In certain embodiments, a method includes building and compiling a function, at run-time, for the pixel format transformation based upon the state.
The patent credits John D. Rosasco and John Stauffer as the inventors.
Cool stuff, even if it may not be immediately seen in an iPod released on Tuesday.
