Method and system for device property for specification of vendor specific protocol features

摘要

One or more vendor extensions that may be communicated to and/or from a device that may communicate via media transfer protocol (MTP) may be specified within an extension of the MTP. The vendor extension may comprise vendor specific information such as proprietary supported features. Vendor extensions may be indicated as a device property and may be communicated to another device during initiation of communication. Supported vendor extensions may be specified in an MTP DevicePropDesc dataset as a response to a request such as a MTP GetDevicePropDesc operation. Alternatively, data from a current value field of an MTP DevicePropDesc dataset may be returned in response to a GetDevicePropValue operation. An MTP SetDevicePropValue operation may be utilized for selecting a vendor extension. However, the selection may be accepted or rejected by a device. An event may be issued to other devices when a change of vendor extension has occurred.

主权项

1. A method for communicating multimedia information, the method comprising:
specifying, by a circuitry, information associated with a vendor extension of a media transfer protocol (MTP), said information including features enabled by said vendor extension; alerting, by said circuitry, a device of said information to allow said device to accept or reject said vendor extension, said device configured to communicate via said MTP, and said alerting occurring via an MTP dataset that includes device properties and an array of unsigned integers in a string indicating said vendor extension and at least one other extension said device supports; and transmitting, by said circuitry, said vendor extension that said device accepts.
