CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to provisional application Ser. No. 60/507,110 filed Oct. 1, 2003, and incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] a. Field of Invention [0003] The present invention relates to the field of digital audio and video player devices that are preferably portable and receive content either from a secure subscription-based or "a-la-carte" content delivery service or from other participant devices, and more particularly to a portable player apparatus that is in wireless communications with an Internet-based file server and laterally to a peer player apparatus. The present invention also relates to a system and method for delivery and management of such content to such devices. [0004] b. Description of the Prior Art [0005] The development of compressed digital audio and video formats, such as the Motion Picture Experts Group--Layer 3 (MP3) audio compression standard, MPEG 21, Advanced Audio Coding (MC), ATRAC, WMA, FLAC, Ogg-Vorbis and others enabled the growth in popularity of recording, storing, transferring, and playing back digital audio and video data on computers, including personal desktop and laptop computers. In particular, compressed digital audio and video formats enabled more efficient storage and transmission of high-quality audio and video content by reducing the amount of digital data that needed to be stored and transmitted, resulting in data files that could be smaller than 1/10th of the original uncompressed digital file without unacceptably degrading the quality of the output. However, due to computational requirements, consumers were generally only able to access and use compressed and uncompressed digital audio and video on their personal laptop and desktop computers (except for conventional commercially-sold pre-recorded CDs and DVDs, which were playable on standard players connected to home stereos and the like). This severely limited portable use and access to such digital audio and video content in that it required the user to be present at or near his or her computer to see and/or hear the playback, which typically could only be through speakers and/or a screen internal to or connected to the computer and not easily transported in digital format to more favorable listening environments, such as the user's car. [0006] More recently, relatively low-cost, lightweight, compact, portable digital media players ("DMPs") have been developed, e.g., Rios' Karma MP3 player, and Creative's Portable Media Center. These portable devices enable consumers to transfer compressed digital audio and/or video files stored on their computers to the portable devices through the use of associated computer-based software via an external connection, such as a USB or "FireWire" cable, and to play the corresponding media on-demand through their DMPs while not in proximity to their computer. Users most commonly accessed the audio on the device by connecting headphones via a standard jack on the device, although it was also possible to connect a line-out cable to other audio output or recording devices, such as a microphone- or line-input of a standard home stereo system. [0007] Such DMPs originally tended to rely on the use of flash memory, such as compact flash or secure digital, for the storage of audio content, and were capable of holding a maximum of approximately 0.5 to 1 gigabyte of memory. More recently, so-called "portable jukeboxes" have been introduced that can hold an estimated 10,000 songs or more of musical entertainment by including a miniature hard disk recorder in the housing of the device, which can have 40 gigabytes or more of capacity. Portable video players with even greater hard disk capacity have also been developed. [0008] In general, conventional DMPs are capable of allowing their users to (1) transfer compressed media files from a computer to the device through the use of associated transfer management software installed on the computer and a physical connection to the computer, such as a USB cable; (2) store such compressed media files in non-destructive memory; (3) decode for playback any of a variety of compression algorithms; (4) convert a compressed or uncompressed digital file to an analog format, potentially also processing the signal to enhance the resulting sound and images; (5) process and amplify the resulting analog signal; and (6) produce high-fidelity sound and video for the user, which may be played, paused, fast-forwarded, rewound, skipped or replayed instantly and on-demand. Also, typically in the case of audio DMPs (e.g., the Rio Karma), the devices feature a relatively small digital display window that provides information regarding the audio content stored on the device, such as the title and artist, and enables viewing (and in some cases modifying) the sequence of the audio tracks that are currently stored on the device. [0009] Disadvantageously, however, data transfer and advanced sorting and sequencing of selections are difficult or impossible for a user to accomplish unless the DMP is connected to the computer, which does not allow the user to obtain new content or to make other desirable modifications to the content stored on the DMP, such as easily modifying the sequence of the content selections stored on the device while the player device is not connected to the computer. Further, in the case of audio, these players typically do not enable a non-technical user to create and manage custom "playlists" (i.e., fixed song sequences), such that a user can easily develop and use a variety of personalized playlists for use at different times. Also disadvantageously, the display and user interface on these audio devices is typically limited in size, involves the use of multi-functional buttons which are complex for many users and is not touch-sensitive, thereby preventing non-expert users from easily viewing and modifying the listing and sequence of audio tracks stored on the DMP. [0010] A further disadvantage of the prior art is that users are typically required to select content selections one-by-one and then to add them to the device. Such requirement creates an inconvenience for the user since typically the user may prefer variety in the programming, and in many cases may not want to create a selection-by-selection sequence of entertainment, especially in the case of music. Programmed entertainment of this sort is currently available to consumers through traditional broadcast media and through other means that generally require the use of a device connected to a wired input, such as Internet-based streaming, accessible through laptop and desktop computers (and certain specialized wired devices, such as the Streamium audio device made by Royal Philips Electronics), and digital cable television and radio services, accessible through cable-connected television sets. More recently, subscription-based commercial satellite broadcast services have been introduced, such as DirecTV for television and Sirius and XM for radio, which enable consumers to receive hours of programming by selecting among available stations. [0011] However, in all cases involving terrestrial and satellite broadcasts, the user does not have the control to stop, start, rewind, fast-forward, replay or skip any portion of the programming. Also, neither terrestrial and satellite broadcasts, nor Internet-based media services allow the user to call up and access specific new selections on-demand on a portable device that does not have full PC functionality (e.g., a lap top) and is not connected to a wired Internet connection. Accordingly, for the convenience of receiving programming with existing DMPs, the user is required to cede control over delivered content for convenience, or will be required to choose to cede convenience for control. Further, in the case of radio-linked audio player devices, player device reception is typically limited due to physical terrain and geographic features, which can distort radio signals that in all cases need to be continuously present and stable during the audio output to provide the user with a satisfactory entertainment experience. Further, of the forms of media services (e.g., TV and radio) available, only Internet-based streaming and digital cable, each of which require the user to use a stationary wired-device for access (e.g., television set and digital cable decoding box), and satellite broadcasts, which do not permit on-demand access or control by the user, provide digital-quality output, which may be a benefit required by users. [0012] A further disadvantage of the prior art is that a security method is not provided for content owners to enable distribution of content to users, management of the content and deletion/expiration of their content on a subscription basis using only a standalone DMP that is not reliant on the use of associated desktop or laptop computer software, while still maintaining royalty records and rights, especially against secondary party transfers. Content owners and users would also benefit from a way content can be shared laterally across peer-to-peer device transfers to other users of both the personal playlists and the media data content that may be stored in the player device in a way that is secure and that permits only authorized sharing activities. It can be appreciated by one having ordinary skill in the art that the terms "audio", "video", "media", and words of similar import may be used interchangeably throughout this document to describe the relevant content, since methods of digital video content compression, storage, transfer, playback and control can be accomplished by using very similar methods and technologies and are similarly well-known by those skilled in the art. Note that "content," as used in this document, shall accordingly mean any audio or video recording that a user may seek to access, and also shall include any other file type capable of being interpreted by a user, such as a written document stored in digital form or a digitally stored and compressed photograph, which may be similarly transferred, shared and used. SUMMARY OF THE INVENTION [0013] The present invention addresses the problems with the prior art described above. A preferred embodiment of the present invention consists of a portable wireless audio and/or video player apparatus having one or more of the following elements: a peer-to-peer audio and/or video data transfer module to allow communications with another wireless audio and/or video player apparatus; a wireless communication link to an Internet-connected base, a communication software module for requesting one or more audio and/or video data files from an Internet-based database server via the Internet-connected base station; a first security means for enabling the downloading and storage of the requested files; a second security means for the management and playing of the stored files; and one or more software modules for interfacing with a user to effect the foregoing features using a easy to understand interface. [0014] More specifically, the player apparatus according to the present invention is able to function as a standalone device to generate, search and obtain new audio and/or video digital data files (containing content and associated metadata (as defined below)) wirelessly over the Internet, without the need to use an intervening device, such as a desktop or laptop computer that temporarily stores the content data files to be transferred to the portable device, or software that runs on a laptop or desktop computer to manage the transfer and arrangement of content on the portable device. This feature enables a non-technical user to access and use digital audio and/or video content without knowledge of how to operate a computer. Further, to overcome the limitations of the display interface of the prior art, the user interface software according to embodiments of the present invention is designed to enable more complex user functions and data organization, and to display these simply and clearly. Such user interface software permits the device to reasonably and comfortably function for the user as a standalone device while permitting the user to search for new content, manage and modify large volumes of content, and share content across a large number of potential users who may be listed by user ID or name. Moreover, the device obtains files from a server or laterally from another device without using a browser-type application. [0015] It is also a feature of the embodiments of the present invention to provide the user with a flexible programming capability both as to time and selection for the playing of the individual audio and/or video files or groups of files. This includes allowing a user to select and play individual content selections from a broad content library stored in a network on-demand, and alternatively to request that hours of continuous programmed content be playable on demand, which programming will be updated on a periodic basis (e.g., daily), without limiting the user's ability to start, stop, rewind or fast-forward through the program. [0016] It is also a feature of the embodiments of the present invention to provide a means for exporting the data content to one or more of a plurality of output devices, including headphones or a home or car stereo, or another storage and/or playback apparatus such as a desktop or laptop computer. Such export may be via either a wired or a wireless communications link. [0017] It is a feature of the embodiments of the present invention to provide a portable player apparatus that is not dependent on favorable physical terrain and geographic features that are typically associated with wireless communications devices. This is mainly accomplished by the pre-storing of desired audio and/or video data and metadata content while in the presence of a communications uplink for accessing/playing at a later time, at which time a continuous wireless connection is not required for navigating the metadata database or for a satisfactory output of the stored audio and/or video content. [0018] It is a feature of the embodiments of the present invention to provide a secure method for content owners to enable distribution of their audio and/or video content to mass-market consumers on a subscription basis. [0019] In a preferred embodiment according to the present invention, a media distribution system preferably consists of a broadband network system for wirelessly distributing digital media files to multiple standalone portable digital media player devices in which the devices are: (1) dedicated to and optimized for searching for, receiving and playing audio and/or video files, authorized obtainment from a network or peer device, management and search of metadata and media content (even while no network or Internet connection is present), authorized playback and authorized transfer (such as to a peer device or digital computer) of digital audio and/or video files by a user; (2) capable of wirelessly transmitting and receiving audio and/or video data files at "broadband" speeds via conventional broadband protocols, such as that promulgated in the 802.11 standard, both to and from a local network which preferably includes Internet connectivity; and (3) able to communicate with an application service in order to request and download encrypted audio and/or video content and associated metadata. Each portable player device preferably includes at least a first security means that disables playback and transfer of media files, or that selectively enables such playback and transfer when a subscription service is activated. The media distribution system preferably includes one or more Internet-based database servers wherein are stored digital audio and/or video data content in compressed or uncompressed form and associated metadata (i.e., descriptive or associative data concerning the content--in the case of audio, this may include such items as length of track, name of artist, name of song, name of album, encoding format and bit rate), an Internet application server interface that communicates individually with each portable device via a secure certification/authentication link, an upload manager that ensures the secure and efficient delivery of data content files to each of the portable devices, and the communications network, thereby allowing the user to request, download, and store individual titles, groups of titles (i.e. a playlist,) and/or preprogrammed entertainment that fit particular criteria (such as genre or purpose (e.g., work-out, dancing)) on a periodic basis. [0020] The audio and/or video content may be distributed to the portable player devices in encrypted form, capable of being played only when decrypted with a particular private digital decryption key. The portable player device (or apparatus) is preferably constructed with an internal clock that is not settable or re-settable by the user (which is a necessary part of preventing a user from avoiding the expiration and disablement of content for time-based subscriptions), but rather can only be digitally set by establishing a secure and authenticated connection to a secure subscriber network that provides it with accurate time and date information. The portable player device preferably also includes a monitoring module that records the time and date each time a content selection is played or transferred by the device. The monitoring module also preferably includes a reporting module for transferring the monitoring results to the network (via the network's upload manager) when connection is made between the portable player device and the network for any reason. [0021] In a second embodiment according to the present invention, a portable peer-to-peer wireless communication player device for transferring audio and/or video and related files to and from a second portable peer-to-peer wireless communication player device, the portable peer-to-peer wireless communication player device preferably comprises: a wireless transceiver unit for wirelessly communicating with external devices (such as peer devices and digital computers); an audio output unit for playing audio files; a visual output unit for displaying video and/or displaying user interface information (e.g., LCD screen or other existing or hereafter created output technology, which, in the case of user interface information, may also be replaced (as is familiar to those experienced in the art) with a menu-driven audio output means); a controlling computing unit having a user input interface and a microprocessor; a digital storage means for storing digital data; and an included software method for operating the device, wherein the digital data preferably includes audio and/or video data content and playlists. Further, the audio output unit preferably includes one or more from the group consisting of speakers and headphones, and the user input unit may consist of one or more from the group consisting of buttons, keys, joysticks, toggles, switches, keyboards, touch-pads and touch-sensitive screen locations, which may include infrared, resistive, inductive and capacitive sensing means. The software may include one or more of the following modules: a communications module; a processing module; a security module; a user interface module; a resident database management module; a storage and retrieval module; and a play module.
