     BACKGROUND OF THE INVENTION  
       [0004]     The present invention relates generally to the field of distributing media content for use on portable media devices. More specifically, embodiments of the present invention provide methods and systems for distributing media content between portable media devices.  
         [0005]     In recent years, with advances in media technology, in particular the developments in digital electronics, more and more mobile media devices are being produced. In particular, wireless phones are now capable of many media functions are being produced in large volumes. Consequently, it is more and more likely that media content will increasingly be viewed on portable media devices, rather than personal computers. These new portable media devices will be either new products, such as email readers and Internet radios, or existing products with new features, such as wireless phones with media capabilities (as discussed previously), MP3 players, personal digital assistants (“PDAs”), and the like. The success of all these new portable media devices will depend upon the ability to effectively provide desirable media content to the media user that is interesting and of a quality so that the user does not use a less mobile media device, such as a standard personal computer, to access the content. With regard to effective access to media content, it is highly desirable for users to be able to easily select and receive media content for their portable media devices where the reception must be of a high standard.  
         [0006]     As such, there now exists in the marketplace a need for effectively providing the new portable media devices with media content. Currently, media content is, in general, provided to users on memory cards or the like on which the media content is stored. The memory cards storing the media content may be purchased by users of the portable media devices or the users may record content to memory cards for use on their portable media devices using their personal computer and/or other recording device. These methods of obtaining media content, however, either limit the wireless phone user to the media content that is available on pre-recorded memory cards or requires the user to have the knowledge and accessories to access content providers and to record media content to a memory card.  
         [0007]     As an alternative to the use of memory cards, portable media devices may be adapted to directly receive media content through television tuners, satellite radio receivers, and the like. However, with mobile type devices, the reception of media content signals may be compromised by the mobility of the mobile media device due to, among other things, signal reception. Additionally, power usage and the ability of the device to contemporaneously receive and manage video content from multiple sources are problems existing in the art. Further, multiple sources of media content exist that a user of a portable media device must connect to and access to download media content.  
         [0008]     As well as issues concerning the downloading/uploading/reception of media content by portable devices there is also a trend wherein consumers desire to share media content with other consumers. For example, a typical consumer may have media content on his or her portable that he or she may wish to quickly and easily transfer to another consumer&#39;s portable media device. Sharing of media content between portable media devices may be desirable for discussion purposes, when consumers are traveling together, so that a consumer may pass media content created or edited by the consumer, and/or the like.  
         [0009]     Currently, issues may exist—such as digital rights management, media content transfer limitations, etc.—that limit the ability of consumers to effectively share media content between portable media devices. These issues may be caused by a loss of protection of the rights of a content provider when media content is distributed between portable media devices. Additionally, connections and communication between portable media devices may be troublesome. Furthermore, effective management and control of distribution of media content between portable media devices may not be possible.  
       BRIEF SUMMARY OF THE INVENTION  
       [0010]     Embodiments of the present invention solve at least the problems discussed above by providing a method for distributing media content between portable media devices. Offering several applications in the technical arts, embodiments of the present invention provide methods for managing distribution of media content between portable media devices. Further, embodiments of the present invention provide methods for easy and effective transmission of media content between portable media devices.  
         [0011]     Some embodiments of the present invention relate to methods for receiving, storing and/or managing the distribution of media content between wireless phones with media capabilities. In certain embodiment of the present invention, incentives are provided to consumers for distributing media content. In some embodiments of the present invention, media content may be interlaced with advertising prior to entry into distribution channels. In certain aspects, data may be obtained during the distribution of the media content and this data may be provided to the content provider. The media content distribution may be managed to provide for accurate transmission between portable devices.

         [0022]     In the following description, for the purposes of explanation, specific details are set forth in order to provide a thorough understanding of the invention. However, it will be apparent that the invention may be practiced without these specific details.  
         [0023]     Merely by way of example,  FIG. 1  schematically illustrates a method for distributing media content from a content provider between portable media devices. A consumer may obtain media content for a portable media device  120  from a media content provider  110 . In some embodiments, there may be one or more media content providers  110 , which may be television studios and/or broadcasters, radio broadcasters, motion picture studios, data providers, providers of streaming videos, gaming providers, marketing companies etc. Depending on the embodiments, the media content provider  110  may be any entity that provides media content (in any suitable form) that may be provided on demand to a subscriber. In certain embodiments, one or more of the content provider(s)  110  may have agreements with a service provider to provide on-demand content for distribution to subscribers. Such agreements may provide for: (a) per-viewing fees payable from the service provider to the content provider; (b) the insertion of advertisements (by the service provider, the content provider and/or a third-party) into on-demand content provided to subscribers; (c) restrictions upon how the content may be provided (e.g., viewing windows during which certain content may or may not be provided, terms governing the provision of on-demand content, etc.); (d) terms related to digital rights management; (e) terms related to the tracking of content provided to subscribers; (e) subscriber feedback to provided media content; and/or (e) other terms regarding supply/distribution of on-demand content. In other embodiments, the subscribers may be able to directly access the content providers and arrange terms and conditions with the content providers for receiving media content on-demand.  
         [0024]     Systems and methods for obtaining media content for a portable media device from a content provider are described in the following applications: (a) U.S. application Ser. No. ______, filed on a date even herewith by Casey and entitled “MOBILE DEVICE BASE STATION FOR ENHANCED SIGNAL STRENGTH FOR MEDIA SERVICES” (attorney docket number 020366-094310) (b) U.S. application Ser. No. 11/060,222 entitled “MOBILE DEVICE BASE STATION FOR ENHANCED SIGNAL STRENGTH FOR MEDIA SERVICES”; and (c) U.S. application Ser. No. 11/060,633 entitled “MEDIA SERVICES MANAGER FOR BASE STATION”, the disclosures of which are incorporated by reference herein for all purposes. The NPVR Applications also describe in detail how both on-demand and real-time content can be provided to a variety of subscriber devices, including without limitation the portable media devices of various embodiments of the invention. As discussed in more detail in the previously listed applications the portable mobile device  120  may communicate with the content provider via a network  110 . The network  110  may be any of several different types of communication networks. Merely by way of example, the network  110  may be the Internet. In other embodiments, the network  110  may be a telecommunication provider&#39;s network, including for example, an asynchronous transfer mode (“ATM”) network, a time-division multiplexed (“TDM”) network, a wireless network (including, for instance, cellular networks, personal communication service (“PCS”) networks, 802.11 networks, and the like), and/or a cable television distribution network. In many cases, the network  110  may be a composite of a plurality of these (and other) types of networks. In short, the network  105  may be any public or private network capable of transporting media content (e.g., video, audio, data, etc.). In some cases, the network  110  may be capable of transmitting packeted data, for instance, data formatted according to the TCP/IP suite of protocols.  
         [0025]     The content provider  105  may directly communicate with the portable media device  120  or may communicate with the portable media device  120  through a secondary device designed for receiving and/or storing media content, such as a base station (not shown). A user of the portable media device  120  may request delivery of media content from the content provider. In some embodiments of the present invention, a content processor  107  may provide for the management/processing of delivery of media content to the portable media device  120 . In some embodiments, the user of the portable media device  120  may establish an account with the content provider  105  and information regarding the account may be stored in a memory associated with the processor  107 .  
         [0026]     In certain embodiments of the present invention, the content provider  105  may seek to have its media content actively distributed between portable media devices by providing a payment scheme to consumers that distribute the media content. In such embodiments, the media content may contain advertising, product placements, etc. Further, the content processor  107  may use information provided by the user of the portable media device  120  downloading the media content to adjust the marketing content associated with the media content. The content provider may also seek to remunerate consumers for distributing media content to provide that the media content is distributed with all digital rights management tools/registrations etc. intact.  
         [0027]     In certain embodiments of the present invention, the portable media device  120  may include a display screen  121  and/or an operational interface  122 , such as a keyboard, touch-screen and/or the like. Using the operational interface  122  and/or the display screen  121 , the user may select media content stored on the portable media device for distribution to a second portable media device  130 . (It should be noted that there may be a plurality of additional portable media devices  130  to which content is transferred. It should also be noted that a single user might own and/or possess both portable media devices  120  and  130 , and/or a first user might own and/or possess the first device  120 , while a second user might own and/or possess the second device  130 ). Once selected, a transmission processor  124  may process the media content for transmission. Processing may involve formatting the media content into the correct format for transmission to the second portable media device  130 , compression of the media content, application of (and/or maintenance of existing) digital rights management controls to the media content, application of a signature identifying the content provider  105  and/or the portable media device  120  and/or the like. Hence, embodiments of the invention can be configured various digital rights management and/or anti-piracy mechanisms. Merely by way of example, the device  120  might be configured to ensure that, when content is to be transferred to the second device  130 , any anti-piracy mechanisms associated with the content are transmitted with the content (and, as one skilled in the art will appreciate, might in fact be integrated with the content itself). Moreover, in certain embodiments, the transmission processor may not allow the media content to be transmitted until a code/signature etc. has been received from the second portable media device  130  identifying that the second portable media device has clearance from the content provider  105  or an associated party to receive the media content. (As described in the NPVR Applications, personal broadcast channels (“PBC”) can be used to order and/or share content. Such PBCs may be used as one vehicle to share content among portable media devices in accordance with various embodiments of the invention.)  
         [0028]     In some embodiments, the user of the second portable media device  130  may register and/or pay a fee to the content provider  105  to provide for receiving media content that the content provider  105  has rights in from other portable media devices and/or directly from the content provider  105 . Various payment methods may be used, such as periodic payments, per transaction payments, debit accounts, and/or the like. In certain aspects, the user of the second portable media device  130  may simply register with the content provider  105  and provide certain information in order to be able to receiver the content provider&#39;s  105  media content.  
         [0029]     In a set of embodiments, the media content may be transmitted by a transmitter  126  associated with the portable media device and/or received by a receiver  136  associated with the second portable media device  130 . The transmitter  126  and the receiver  136  may be WiFi devices, WiMax devices, Bluetooth devices, infrared devices, and/or the like and may provide for the wireless communication of the media content from the portable media device  120  to the second portable media device  130 . In alternative embodiments, a wired connection may be created between the portable media device  120  and the second portable media device  130  and may provide for the communication of the media content.  
         [0030]     A reception processor  134  associated with the second portable media device  130  may provide for the processing of the media content, and/or a user of the second portable media device  130  may use a user interface and/or a display screen associated with the second portable media device  130  to control/view the media content. Prior to the communication of the media content from the portable media device  120  to the second portable media device  130 , the portable media device  120  may require confirmation that the second portable media device  130  is authorized to receive and/or use the media content. In certain embodiments of the present invention, the reception processor  134  may create an electronic record of the reception of the media content by the second portable media device  130  and/or may send the electronic record to the portable media device  120 . The electronic record may include a reference identifying the media content and/or a signature identifying the second portable media device  130 . The portable media device  120  (and/or a user thereof) may send a second electronic record (which might comprise the first electronic record) to the content processor  107  to identify the distribution of the media content from the portable media device  120  and the second portable media device  130  and/or to request authorization to transfer the content. In other embodiments, the second portable media device  130  may transmit the electronic record over the network  110  to the content processor  107  associated with the content provider  105 .  
         [0031]     To provide for payment to the user, the content processor  107  may store information from the electronic record and provide for payments to be made to the user of the portable media device  120 . The content processor  107  may also collect information from the electronic record concerning the user of the second portable media device from which data concerning the distribution of the media content may be ascertained and the demographics of consumers receiving the media content interpreted. The content provider  105  may use distribution information received by the content processor  107  for marketing purposes and/or negotiations with advertisers.  
         [0032]      FIG. 2  is a flowchart illustrating a method for distributing media content between portable media devices, in accordance with an embodiment of the present invention. In the first step  205 , a user of a first portable media device may send a request to a content provider or a party operating a network making media content available for media content. As discussed previously, the provider of the media content may be a party that operates a network for portable media devices, such as a wireless phone network operator, and obtains media content from media content providers to supply to the wireless phone network operator&#39;s clients. In step  210 , one or more processors may be used to obtain, format, compress, etc. the media content for delivery to the user (e.g., an NPVR, a ROD server and/or a media conversion server, each of which is described in further detail in the NPVR Applications, may be configured to provide such services.) In certain aspects, the media content may be formatted for transmission to a portable media device and/or an associated device capable of capturing the media content for the portable media device. In other aspects, marketing materials and/or content may be inserted into the media content, as described in the NPVR Applications, for example. In some cases, this marketing content may be selected based upon a profile of the user stored in a memory associated with the processor. In yet further aspects, digital rights management protocols and/or the like may be associated with the media content to provide protections for the content provider.  
         [0033]     In step  220 , media content is transmitted to a portable media device from the content provider (e.g., via an NPVR, subscriber connectivity device and/or other appropriate device). The media content may be transmitted over a network, such as the Internet, or the like. Once received, the media content may be stored on the portable media device. In certain aspects, the media content may be transmitted to a device associated with the portable media device, such as a base station, before being transferred to the portable media device.  
         [0034]     In step  230 , media content from the portable media device may be transmitted to a second portable media device. In certain aspects transmission from one portable media device to another portable media device may be performed wirelessly using Blue tooth technology, WiFi technology, infrared technology, and/or the like. In alternative aspects a hard connection may be made between the portable media devices to provide for the transfer of the media content.  
         [0035]     In step  240 , an electronic record of the transmission may be created by the portable media device receiving the media content. The electronic record may include the identity of the portable media device receiving the media content, information concerning a user or users of the portable media device, etc. In step  250 , the electronic record is communicated to the content provider (and/or some party associated therewith). In some embodiments, the electronic record may be communicated to the portable media device that shared the media content with the receiving portable media device. In such embodiments, the user of the sharing portable media device may communicate the electronic record to the content provider or a party distributing the content provider&#39;s content to register the distribution of the media content by the user. In other embodiments, the electronic record may be communicated over a network to the content provider or to a party distributing content for the content provider.  
         [0036]     In step  250 , in certain embodiments of the present invention, the content provider and/or a person associated with the content provider may provide some form of recompense to the user of the portable media device who distributed the media content from their portable media device to a second portable media device. Recompense may be monetary, access to additional media content and/or the like.  
         [0037]      FIG. 3  is a flow-type schematic illustrating the transmission of data between portable media devices in accordance with an embodiment of the current invention. In certain embodiments of the present invention data may be packetized and transmitted in packets between portable media devices. In step  310  a processor associated with a first portable media device may identify data for sharing with a second portable media device, according to user commands or the like. The processor, after selection, may format the data into a plurality of data packets.  
         [0038]     In step  320 , the data packets may be communicated by the first portable media device and/or a device associated with the first portable media device to a second portable media device and/or a device associated with the second portable media device. Transmission may be by wireless communication means, via a hard connection and or a network. At the beginning of the communication a checksum may be sent to the second portable media device. In step  330 , a processor associated with the second portable media device may perform a checksum type analysis and compare the amount of packets of data received or the like with the checksum.  
         [0039]     In step  340 , if the processor determines that not all of the data packets have been received it may send a signal to the first portable media device to request either continuation of an interrupted data transmission and/or a complete resending of the data packets. In certain embodiments, the packets of data may contain information so that the processor may be able to identify the missing packets and request the transmission of the missing data packets. In certain embodiments, multiple communication networks, devices and/or the like may be used to transmit the data between the portable media devices and the processor may reconstruct the media content from the data packets received. In step  350 , an electronic record of the communication of the data packets between the portable media devices may be created by a processor associated with one of the portable media devices. The electronic record may include identification of the data packets sent and identification that all packets were successfully transmitted and received.  
         [0040]     It should be noted that the methods, systems and devices discussed above are intended merely to be exemplary in nature. Consequently, various embodiments may omit, substitute and/or add various procedures and/or components as appropriate. For instance, it should be appreciated that in alternative embodiments, the methods may be performed in an order different than that described.  
         [0041]     It should also be appreciated that the methods described above may be performed by hardware components and/or software programs, and thus may be embodied in sequences of machine-executable instructions, which may be used to cause a machine, such as a general-purpose or special-purpose processor or logic circuits programmed with the instructions, to perform the methods. These machine-executable instructions may be stored on one or more machine readable media, such as CD-ROMs or other type of optical disks, floppy diskettes, ROMs, RAMs, EPROMs, EEPROMs, magnetic or optical cards, flash memory, or other types of machine-readable media suitable for storing electronic instructions. Merely by way of example, some embodiments of the invention provide software programs, which may be executed on one or more computers, for performing the methods described above. In particular embodiments, for example, there may be a plurality of software components configured to execute on various hardware devices (such as an NPVR, ROD server, MCS, etc.). Alternatively, the methods may be performed by a combination of hardware and software.  
         [0042]     Having described several embodiments, it will be recognized by those of skill in the art that various modifications, alternative constructions, and equivalents may be used without departing from the spirit of the invention. Accordingly, the above description should not be taken as limiting the scope of the invention, which is defined in the following claims.
