An audio signal receiving apparatus includes a sound source information receiving portion to receive sound source information containing sound source type information indicating a sound source type of the audio signal being transmitted through channels and externally connected equipment playback sound source information indicating a sound source type of the audio signal being played back by the externally connected equipment from externally connected equipment, an audio signal receiving portion to receive the audio signal from the externally connected equipment, and a playbackable sound source setting portion to determine and set a sound source type of the audio signal that can played back to a playbackable sound source based on the sound source information. The playbackable sound source setting portion sets a sound source type of the audio signal being played back by the externally connected equipment to the playbackable sound source as an externally connected equipment playback sound source.

A non-volatile memory wherein bad columns in the array of memory cells can be removed. Substitute redundant columns can replace the removed columns. Both of these processes are performed on the memory in a manner that is externally transparent and, consequently, need not be managed externally by the host or controller to which the memory is attached. The bad column can be maintained on the memory. At power up, the list of bad columns is used to fuse out the bad columns. The memory may also contain a number of redundant columns that can be used to replace the bad columns.

The present invention is intended to provide an audio playback apparatus which is capable of randomly reproducing music on an album basis or a folder basis. In a sound source in which a plurality of music files are hierarchically recorded, a unit of music file groups in each of which music files are reproduced in a batch is specified, music file groups are randomly selected in the specified unit, and all music files included in each of the selected music file groups are reproduced.

An electronic device can play back media items using a random playback mode. To ensure that related media items are played back in a proper order (e.g., live music is played back in concert order), the electronic device can define metadata or other data coupling related media items in a predefined or preset sequence. For example, related media items can include metadata tags identifying the previous and next media items to play back in the sequence. As another example, the electronic device can store a listing of media items of a sequence and the order in which to play them back. When the electronic device reaches a media item that is part of a preset sequence during random playback, the electronic device can identify at least the subsequent media items in the sequence, and insert the subsequent media items in the playback queue. The electronic device can then play back the entire sequence before moving to the next media item in the playback queue.

A digital downloading jukebox system including a mechanism for delivering custom services to a recognized user is provided. For example, information specific to a recognized user may be stored and optionally may include a recognized user avatar representative of the recognized user. The user avatar may be an image, video, and / or animation, which may be displayed on and / or played through the jukebox. The user avatar may be associated with transactions associated with the user. For example, an avatar may be displayed when a playlist of the recognized user is played, when a message is sent, etc. In other examples, the avatar may introduce instances of media by playing an audio and / or video message, and the avatar may sing, dance, etc. while an instance of media is playing.

In an optical disc having an RFID tag, disc control information needed for control of reproduction of the content recorded in the disc body of the optical disc is stored in the RFID tag. Thereby, even if the content recorded in the disc body is illegally copied in some way, common optical disc apparatus incapable of reading RFID tags cannot read and copy the disc control information stored in the RFID tag. Accordingly, unauthorized copying of the content recorded on the optical disc can be reliably prevented without the use of special cryptographic technology.

A vehicle audio system is provided that includes an audio receiver having a radio tuner and a random access media reader adapted for accessing audio data files such as those stored on a compact disc. The audio system includes a display having a plurality of display formats for displaying a label associated with an audio data file, and a display switch having a first mode operable for shifting the display from one of the plurality of display formats to another of the plurality of display formats, a second mode operable for setting the default display format to another display format, and a third mode operable for initiating sequential display of a plurality of display pages to displaying the label.
