Hand held apparatus for simulating two way connectivity for one way data streams

摘要

A hand held device for use to separately render associated data is disclosed. The hand held device includes a display element, a processor, and a communication interface. The communication interface operates to receive rendering commands of the associated data from a host device, which received the associated data in conjunction with primary data, and subsequently separated the associated data from the primary data. The processor causes the associated data to be rendered on the display element. The hand held device further includes an enclosure for housing the display element etc., which has physical dimensions that are suitable for hand held usage while viewing the primary data, which are separately rendered.
