Abstract: The present invention provides an intelligent client with a catalog of available streams and keeps a persistent record of each stream to which the user listens and the point at which they stop in each stream. An example method receives a selection for a streamed media file at a mobile communications device. The received selection is sent to a server via a mobile communications network and/or a public data network. A portion of the streamed media file that was not previously presented by the device is received from the server, if the streamed media file was interrupted during a previous presentation. The received portion of the streamed media file is presented on the device.

Abstract: Methods and systems for scrolling through content of media. An example method performed on a cell phone receives an index of segments from a server over a cellular network and a public data network. The received segment is presented based on the received index of segments. A request for a media file associated with the presented segment is generated and sent, if a user selection signal is received. The index of segments includes information that associates a preselected segment of a full media file with the full media file. A request for a segment associated with the received index of segments to the server is generated and sent and the requested segment is received from the server based on the request before presenting. The requested media file is received and presented after the server processes the request for the media file.

Abstract: Systems and methods for recording viewing of an advertisement on a mobile computing device. In an example method the mobile computing device initiates presentation of a digital content file having one or more associated advertisements, transmits from the mobile computing device at least one of an identifier for the presented digital content file or an identifier of the associated advertisement over a wireless network to a server, and updates an advertisement impression count at the server based on the transmitted digital content file identifier or associated advertisement identifier. The digital content file and associated one or more advertisement may be received from another mobile computing device. The mobile computing devices include cellular phones.

Abstract: Systems and methods for allowing communication between two or more proximate mobile computing devices. In one method a first device detects the presence of a second device. A signal is sent by a first device for requesting a comparison of the lists of media files. The signal can be sent to a second device (or to a server over a wireless network) and may include the list of media files associated with the first device. The second device sends a list of media files to the first device after receiving the signal. An alert is outputted if a list of media files associated with the first device is determined to be comparable to a list of media files associated with the second device based on one or more predefined parameters.

Abstract: Methods and apparatus to enable a distinction between “new” and “used” digital content and to enable a market in used digital content files between mobile phone terminals and an electronic store, securely, by means of a wireless telephony network and a server complex to handle contents right management, transaction reporting, inventory, content delivery, payment, and billing. A server receives a signal generated by a wireless user device that was sent over a wireless telephony network. The signal indicates an election for returning at least one previously purchased digital content item. The server deletes user rights for the at least one digital content item identified by the received signal and sends information to the user device that generated the signal. Access to the associated digital content item at the user device is removed according to the sent information.

The user interface includes two or more input keys. Each input key is associated with a query symbol and the number of input keys is less than the number of distinct letters, characters, and symbols.

Abstract: Systems and methods for securely performing digital commerce. A user device provides a first key and a random number to a server over a first network, encrypts the random number and a user identifier using the first key, and sends the encrypted information to the server via a second network. The server generates an encryption of the random number, the user identifier, and a second key using the first key. The user device receives, decrypts and stores the second key. If the user device wants digital content, the server encrypts the digital content using a digital content key and encrypts the digital content key using the second key. The user device receive the encrypted contents, decrypts the digital content key using the second key and decrypts the digital content using the decrypted digital content key. Digital content can be passed to other user devices.
