Abstract: Methods, systems, and media for indicating digital media content quality to a user are provided. In accordance with some embodiments, methods of indicating digital media content quality to a user are provided, the methods comprising: receiving a request for authenticated media content; receiving a device identification associated with a media device; comparing the device identification to a registered device identification using a hardware processor; and upon determining that the device identification matches the registered device identification, causing an authenticity token associated with the authenticated media content to be transmitted to the media device.

Abstract: Systems, methods, and media for providing secure content information are provided. In some embodiments, systems for providing secure content information are provided, the systems comprising: a processor that creates a payload, creates a validation value, securely stores the validation value in association with a content distribution, and stores the payload in association with the content distribution. In some embodiments, systems for providing secure content information are provided, the systems comprising: a processor that receives a payload associated with a content distribution, creates a first validation value for the payload, recovers a second validation value associated with the content distribution, compares the first validation value and the second validation value, and determines if the payload has been tampered with.

Abstract: Methods, media, and devices for providing a package of assets are provided. In some embodiments, methods of distributing a package of assets to a portable device are provided, the methods comprising: identifying the portable device; identifying an asset that correspond to the portable device and the package of assets; and transferring the asset and a definition of assets that corresponds to the package of assets to the portable device. In some embodiments, methods of presenting a package of assets on a portable device are provided, the methods comprising: providing information for identifying the portable device; receiving an asset and a definition of assets, wherein the asset corresponds to the portable device; and presenting the asset according to the definition of assets.

Abstract: Methods, media, and systems for access control to content distributions are provided. In some embodiments, methods for access control to a content distribution are provided, the methods comprising: detecting at least two of a subcode, a watermark, hidden bits, a wobble track, and a valid wobble track code in the content distribution; determining whether the content distribution is an authorized product based on the detecting; and performing an action based on whether the content distribution is determined to be an authorized product.

Abstract: The invention is a system for recording and reading both program data and acoustical control data and playing back the data to optimize performance of audio reproduction and recreate the effect of an original acoustic environment. The system has a recording apparatus, a playback apparatus and a recording media. The recording apparatus produces recording media having both acoustic control information and audio data. The playback apparatus gives the user some ability to override otherwise automatic parameter adjustments. Optionally, a metadata display system takes information about the physical arrangement of instruments and other characteristics of the recording session and the recording studio and makes that visually available to the listener. A player type register identifies the characteristics of the playback device to cause an adjustment of the characteristics of the playback system.

Abstract: A method and apparatus for sharing a digital access license by receiving a request to share the license, identifying a current license to be shared, preparing a loaner-license according to the current license and conveying the loaner-license to a borrowing client.

Abstract: A program distribution system is disclosed for the simultaneous release of a program at a plurality of locations. The locations may include local broadcasters, or even individual devices. A program is modified so that it cannot be played without a release control signal and is then copied and distributed .either fixed in a media or electronically, i.e. via private network, the Internet, etc.) At the receiver the receiver first detects the release control signal and then replays the program at will. The program may include a time stamp in which case the receiver cannot replay the program until a control indicative of a current time/date corresponding to the date stamp. Alternative the program can be encrypted in which case the release control signal includes the decryption key. The release control can be broadcast over a tv channel, a radio channel and so on and is preferably imbedded into the signals of the standard tv or radio signals.

Abstract: Methods and apparatus for recording and playing back multi-channel digital audio having different sampling rates for different channels are provided. Recording is accomplished by sampling a plurality of channels of audio data and arranging the samples of the plurality of channels of audio data in most nearly the order needed during playback. Playback is accomplished by accessing the samples of the plurality of channels of audio data and converting the samples from digital to analog form. The playback may include deriving audio signals in a different format from the format in which the programming is recorded.

Abstract: An ABX testing device for comparing for example two video or audio programs is provided to determine if the two programs can be distinguishable. The device selects randomly one of the programs and the tester can listen or view and compare sequentially the random selection to either of the programs. The tester then can vote by designating one of the programs as being the randomly selected program. The designations are accumulated and statistics are generated regarding the same. Preferably the device includes a control box, a switch mechanism and a PC coupled to both by standard parallel cable.
