Abstract

Methods and apparatuses for media data communication for improved bandwidth utilization are provided. A client device communicates profile information to a server. The server maintains media content data and first metadata category information associated with the media content data. Based upon the profile information, a determination is made as to whether the client device is to utilize the first metadata category information. If to be utilized, media content data as well as the first metadata category information is provided to the client device. If a non-utilization determination is made, media content data is provided without the first metadata category information. In exemplary embodiments, first metadata category information can relate to any of the following: closed captioning, speaker virtualization, three dimensional rendering, global positioning, audio and/or video codecs, volume control, and the like.

Claims

1. A method for media data communication by a computerized server, the method comprising:

receiving encrypted profile information of a client device by the computerized server in response to a query from the computerized server, the profile information identifying an accessible function of the client device;

maintaining by the computerized server, first metadata category information, second metadata category information, and media content data, the first and second metadata category information each associated with the media content data, and the media content data is preexisting on the client device;

determining, based on the profile information, whether the client device is to utilize either the first metadata category information or the second metadata category information for the identified accessible function of the client device;

based upon a determination of utilization of the first metadata category information, transmitting the first metadata category information to the client device without transmitting the second metadata category information; and

based upon a determination of utilization of the second metadata category information, transmitting the second metadata category information to the client device without transmitting the first metadata category information.
