The underlying invention generally relates to the field of
mobile computing,
wireless communication, and interactive
multimedia applications in mobile communication networks with high-speed access. Particularly, it refers to a customized
multimedia information channel
system presenting advertisement information (124a) and, if desired, other
multimedia streams on a mobile communication and computing device (100) equipped with a
Liquid Crystal Display (102) designed to meet modern business-to-business (B2B) requirements. In this connection, interactive operation is guaranteed by a digital
wireless data and control link (108) between said
mobile computing device (100) and a product (122) to be advertised. In contrast to conventional solutions, said
mobile computing device (100) comprises a
User Control Board (101) with an
Application Programming Interface (105c) providing an intercommunication between a
software routine (105b), said
User Control Board (101), the display (102) of said device (100), and an additional hard-disk drive (111) for storing content data (124a) to be rendered on the display (102) of said device (100). Thereby, said
User Control Board (101) is capable of communicating with a specific
file server (118) over a bi-directional
air interface (108) and a
Wireless Local Area Network (120) by transmitting user requests (123) and receiving content information (124a), receiving control information (124b) from a
remote control device (116), and transmitting status information (124c) to the
remote control device (116). Furthermore, said device (100) is capable of receiving identification information (126) about the product (122) from a tag device (114) attached to said product (122).
