Embodiment Construction

[0022] The many novel teachings of this application are described below with specific reference to presently preferred embodiments. It should be understood, however, that such embodiments provide but a few examples of the many advantageous uses of the novel teachings herein. In general, statements made in the specification of the present application do not necessarily define any of the various claimed inventions. Furthermore, some statements may apply only to some inventive features and not to others.

[0023] figure 1 A presently preferred embodiment of a mobile multimedia terminal (or MMT) is described. The MMT provides an interactive mobile environment. In the presently preferred embodiment, DVB-T receiver 102 is controlled by CPU 104 . The DVB-T receiver 102 is capable of receiving digital TV broadcasts according to the DVB-T standard. DVB-S (satellite) and DVB-C (cable) broadcasting are also standardized and available. The DVB-T standard specifies broadband channels...

Abstract

A method and device for providing an interactive mobile multimedia terminal (100). The mobile multimedia terminal (or MMT) (100) allows receiving a broadband data stream using a digital data broadcast receiver (102), such as DVB-T. Interactivity is achieved using built-in local or cell-scale communication links (116 and 112). The local link (112) can be WLAN or Bluetooth (low power RF transceiver). The large cell scale communication link (116) may be a mobile station link such as GSM, CDMA, TDMA, or the like. If no local point of attachment is found, a mobile station with a Bluetooth link can be used as an IP router or as a portable base station for large cell-scale communications. The MMT (100) integrates DVB-T reception, digital display and communication links to provide interactivity in a mobile environment. The MMT communication link with the mobile station enables it to be used as an extended display for the mobile station.

Description

technical field [0001] The present invention relates to multimedia terminals, and more particularly to interactive multimedia terminals using DVB (Digital Video Broadcasting) in a mobile environment. Background technique [0002] Advances in semiconductor technology and software have accelerated the boom in wireless data communications. These advances have allowed the transmission of audio and data signals over digital networks. [0003] Digital and mixed-signal systems offer many advantages over older analog systems. An important advantage is that digital systems transmit and receive more information at higher rates. Analog systems are limited to transmitting audio and video at a rate of 64 Kbps (kilobits per second), digital systems can compress these transmissions to transmit eight times the information at the same rate. Furthermore, faster processors allow digital systems to transfer bits at ever-increasing rates. By using compression programs and faster processors t...
