Abstract: A system, method, and computer-readable media are disclosed for remotely controlling playback of content stored on a device. The system, method, and computer-readable media can transmit state-based commands from a host unit to the device in order to control playback of the content. The host unit can control playback of the content without requiring the device to transfer the content to the host unit. The host unit can also be updated as soon as there is a change in any state of the device.

Abstract: A method to expose information about a set of data objects to a master device is provided. A benchmark sequence indicator is used in connection with a set of sequence indicators that are each related to data objects (such as media files on a device) to satisfy multiple independent requests for information about certain objects that satisfy sequence criteria conveyed from multiple requesting applications. An embodied data structure includes a set of properties associated with a data object as well as a sequence-identification field that also corresponds to the data object and that is populated with an object sequence indicator that indicates when a change occurred to the data object.

Abstract: A system and method for removable storage content transfer. A removable storage medium is passed between a terminal and a device, and a device file stored on the removable storage medium is used to communicate media content and other information between the terminal and the device. The device file may include “session information,” such as information that can be used to represent a network or direct connect session between the terminal and the device file. The session information may include, for example, media content and header information. The device file may allow the terminal to treat the removable storage medium as a locally connected device in some situations. For example, the terminal may create a device stack using device parameters stored on the removable storage medium, and use the device stack to communicate with the device via the removable storage medium.

Abstract: A protocol and related techniques and platforms allow vendors to selectably extend the Media Transport Protocol (MTP), or other defined protocols to implement vendor-specific commands, data fields, instructions and other extension sets. According to embodiments of the invention in one regard, one or more extension space may be utilized to derive independent extension sets, in part by separating the extension space according to a unique identifier assigned to or associated with a given vendor. In embodiments that unique identifier may be or include an Internet DNS (Domain Name System) domain name, or other extension set name or identifier. According to the invention in one regard, because a DNS domain name may be independently registered and secured by participating vendors or manufacturers and by definition uniquely assigned, the separation of vendor extension sets by that type of name may be automatic and free from conflict.

Abstract: A system and related techniques generate an interrogation request from an initiator device, such as a client desktop machine or other machine, to a mobile or other media player, such as a digital camera, MP3 player, video camera or other device or hardware to enumerate the media content contained in that device, along with associated properties. The collection of binary objects which encode the content, such as digital photographs, encoded audio files, digitized video or other media, may include or have associated with them a set of corresponding object properties which help to define each object, such as by defining a pixel color depth, audio codec or other property or attribute.

Abstract: A system and related techniques relate to the retrieval of a media object list with associated properties from a media device such as a digital video camcorder, audio player or other source or device. According to embodiments the retrieved list or set of media objects and their attributes or properties, for example a song list along with song length, codec, artist and other information may be retrieved from the source device, along with a representative sample of the media or content of each object. So the title which identifies a song may be accompanied by a short sound clip of a representative sample of that song, or a title identifying a digital video movie may be accompanied by a short video clip of an introductory portion of that movie.
