Abstract
A host device is disclosed. The host device includes a processor and a control mechanism. The processor operates to receive primary and associated data, the associated data being targeted for different recipients, decode and separate the associated data from the primary data, and cause the associated data to be correspondingly rendered on separate hand held devices. The processor also operates the control mechanism to control a separate display apparatus to separately receive and render the primary data.
