Embodiment Construction

[0041] Various embodiments of the invention describe methods of fragmenting XML-based data, as in an XML document at a server or similar network element, and the subsequent formation and transmission of the fragmented data from the server to the receiver . These embodiments of the invention include two types of XML segmentation techniques, namely, brute force-based segmentation and syntax-based segmentation. Segmentation based on brute force involves arbitrary segmentation of XML data based on the MTU size regardless of the syntax structure of the XML content. Syntax-based segmentation involves segmenting XML data based on the MTU size in consideration of the underlying syntax structure of the XML content. In addition, payload representations for each of these techniques are described here. exist figure 1 A high-level view of this process is shown in . Timestamp 100 is shown associated with original XML document 110 . The original XML document 110 is divided into two frag...

Abstract

A system and method for partitioning XML-based content into fragments, where transport packets are generated for encapsulating the fragments and streaming the encapsulated fragments to a receiver, such as a mobile device. Fragmentation of the XML-based content can be performed either with or without regard for any underlying XML syntax or structure. In either case, certain relevant fragmentation information is encapsulated with the fragmented XML-based content in the transport packets that allow for various reconstruction, error concealment, and retransmission schemes for presenting the streamed XML-based content on / to the receiver.

Description

technical field [0001] The present invention relates generally to XML-based content segmentation. In particular, the present invention relates to various methods for fragmenting XML-based content, while defining and describing fragments, thereby allowing the intended recipient to use the XML-based content even when some fragments are missing. Background technique [0002] This section is intended to provide a background or context to the invention that is recited in the claims. The descriptions herein can include concepts that can be explored, but not necessarily those that have been previously thought of or explored. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section. [0003] Rich media content generally refers to content that is graphically rich and contains mixed or multiple media types, including graphics, tex...
