Abstract

Apparatuses, methods and storage medium associated with content distribution and consumption are disclosed herein. In embodiments, an apparatus may include a decoder and a presentation engine. The decoder may be configured to receive and decode a primary content. The presentation engine may be configured to process and present decoded primary content. Processing of the decoded primary content may include identification of a feature in a frame of the primary content, and integration of a secondary content with the feature. Presentation of the decoded primary content may include presentation of the decoded primary content with the secondary content integrated with the feature of the frame. Other embodiments may be described and/or claimed.

Dependent claims

An apparatus for consuming content, comprising:

one or more processors;
a decoder to be operated by the one or more processors to receive and decode a primary content;
and
a presentation engine coupled to the decoder, to be operated by the one or more processors to process and present decoded primary content, wherein process of the decoded primary content includes identification of a feature in a frame of the primary content, and integration of a secondary content with the feature, and wherein presentation of the decoded primary content includes presentation of the decoded primary content with the secondary content integrated with the feature of the frame;
wherein the presentation engine includes a feature tracking function to identify the feature in the frame;
wherein the feature tracking function is to calculate a homograph Hwi between frame-i and the feature, as follows:
