DIGITAL AUDIO BROADCAST RECEIVER

摘要

A receiver is described for receiving digital data broadcasts from a Push-Pull gateway. The receiver is equipped with a demodulator (406), deinterleaver (405) and turbo broadcast decoder (408) for parsing and rendering the received broadcast data. Additionally, the receiver is also equipped with a GPS module and an uplink module for communicating with the Push-Pull gateway or a content provider center. The GPS module can also be used to assist in filtering broadcast data specific to the receiver's location. The uplink module is used to transmit profile information defining the client's desired broadcast format. The uplink module is also used to dynamically update private keys that are provided to clients for authentication and decoding purposes. The uplink together with the turbo broadcast layer module is also used for "buy" activities.
