A data transfer module on a device receives a request from a program to download a file, and accesses a remote service to begin downloading the file. The data transfer module receives bytes of the file from the service and stores those bytes in a temporary file. The program can also make read requests including an offset into the file. In response to such a request, the data transfer module requests from the service the portion of the file beginning at the specified offset into the file. The data transfer module receives the requested portion of the file from the service and stores those bytes in the temporary file. The program can then read and use the bytes from the file that were downloaded based on the offset prior to the entire desired file being downloaded. Meanwhile, the data transfer module continues downloading the remaining portions of the file.

Nonconsecutive file downloading

An arrangement for exposing self-describing device-hosted services on a client device to a host application or processes over MTP (Media Transfer Protocol) is provided by which an MTP extension comprising new MTP commands enables the device-hosted services to be backwards and forward compatible with existing MTP implementations. The new MTP commands in the extension enable discovery by the host of device-hosted services provided by a connected client device. In an illustrative example, the device-hosted services include storage services which supplement traditional MTP storages with service features, functional device services which support message-based interaction between the host and client device, and information services which may simply present a rich, static dataset of information to the host rather than providing additional storage or functional capabilities. These device-hosted services advantageously enable richer communication between the host and client device.

Device-hosted services over media transfer protocol

A modularized broadcast receiver driver architecture includes one or more control nodes, under control of a network module, that perform a series of one or more functions to receive a broadcast signal and extract content information from the signal. None of the multiple control nodes requires knowledge of the network type via which the signal is being received. Rather, a network module is aware of the network type and configures the control nodes to carry out their respective functions.

Modularization of broadcast receiver driver components

A component, such as a Component Object Model (COM) object, operates as an intermediary between an Application Programming Interface (API) extension or plug-in and a driver. The component allows additional objects to be aggregated onto the component, and/or sets one or more setting values for a received request so that an I/O call associated with the request can be completed in a manner that is compatible with other I/O calls. The component may also return, in response to a particular request, a stream index associated with the component.

System and method for supporting new and existing extensions to application programming interfaces

An extensible framework for tuning to programming sources includes tune request objects and tuning space objects that are used to maintain and pass information regarding how to tune to a particular program. The extensible framework can be easily modified by creating, deleting, or modifying tune request objects and tuning space objects without requiring changes on the part of applications interacting with the framework.
