Abstract

A method of rendering content (400) in a networked or Internet environment is disclosed. The method comprises analyzing the buffered content (402) based on semantics of the content and generating a semantically analyzed buffered content, the semantically analyzed buffered content having a plurality of semantic boundaries, identifying a logical end point (404) in the semantically analyzed buffered content, the identified logical end point being closest to the size of the semantically analyzed buffered content and rendering a portion of the semantically analyzed buffered content (406) till the identified logical end point with a streaming application. The disclosed method can be useful for televisions capable of operating in an Open IPTV environment, for DLNA client devices and any video rendering application for web streaming services.
