摘要:
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. According to embodiments of the invention, the initiator may communicate with the responding device using a media-aware protocol supporting an aggregate object property request, such that the initiator may identify one or all of the set of properties paired with all of the objects to be returned along with an enumeration of those objects. The initiator may then present, for example, a list of song titles along with the corresponding artist, track length, codec, display skins or other attributes or properties to a user, for example to select, delete, copy or otherwise manipulate the underlying objects, which may in one regard be separately retrieved from their identifier and properties. Because properties may be retrieved in conjunction with, at the same time and using a unified retrieval scheme, the need to query each object identifier one by one for associated properties is removed. The throughput and responsiveness of object property retrieval is therefore significantly enhanced.

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.

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.

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. Vendors or manufacturers, such as makers of digital cameras, digital video cameras, audio players such as MP3 or other players, software vendors or others may therefore freely design extensions to the Media Transport Protocol or other protocols, without a need to clear those extensions with a standards body and with confidence that their commands, data fields and other extensions may be free from overlap with that of other manufacturers.
摘要:
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. According to the invention in one regard, that representative sample may be generated in the source device and encapsulated into the set of properties which are passed with the object identifier to an initiator device, such as a user's computer accessing a video camera for downloading. A media object which is stored in monolithic binary format with no predetermined internal samples may nevertheless be accessed and sampled to allow a user to view or listen to representative content, through encapsulation of a sample in the properties passed via an underlying media transport protocol.

A system, method, and computer-readable media are disclosed for retrieving configuration files from host units to devices. The system, method, and computer-readable media can, through a media device, detect when a surrounding condition has changed so that the media device can benefit from at least one configuration file. If the media device determines that a change to a surrounding condition has occurred, the media device can then retrieve a configuration file from a designated host unit.

A computer-implemented method and system are provided for supporting hardware devices that are connected to the computer via a network. The existence of any hardware device connected on the network is detected in the method. Information descriptive of the connected device is then obtained, either from the device or from the user. Based upon the obtained information, a logical representation of the connected device is created. The driver for the detected device is then located and installed. From this point on, the network-connected hardware device appears to the computer in the same manner as a locally connected hardware device.

摘要:
A technique and associated mechanism is described for registering event metadata at a first site, transferring the event metadata to a second site using a portable module, and processing the event metadata at the second site. A user can register the event metadata at the first site in the course of consuming broadcast content. Namely, when the user encounters an interesting portion of the broadcast content, the user activates an input mechanism, resulting in the storage of event metadata associated with the interesting portion on the portable module. The second site can upload the event metadata from the portable module and, in response, provide content associated with the event metadata, including recommended content associated with the event metadata.
