<p>A system and a method for communicating video data associated with content across a network are disclosed. A server partitions the content into a plurality of tiles where each tile includes a subset of the content and index data describing a relationship between a tile and one or more adjacent tiles. Each tile is then encoded as a video frame, for example each tile is encoded according to the H.264 standard. The plurality of tiles are then transmitted to a client which combines the plurality of tiles using the index data to locally recreate the content. The client associates a predetermined viewport tile with a client viewport representing the area of the content that is visible in a client display device to allow viewing of the content while tiles not associated with the client viewport are cached to expedite subsequent retrieval.</p>
