A broker application server for facilitating communication between one or more senders and one or more receivers over a digital packet network. Each receiver receives data in a preferred format. Information identifying the preferred data format of each receiver is stored in a database in the broker application server. The broker application server receives digital packets addressed to a receiver. It extracts data and address information from the packet and optionally decrypts the data. It examines the data to identify the data format. If the data is in the preferred format of the addressed receiver, the broker application server optionally encrypts the data, formats it into a packet, and transmits it to the appropriate receiver. If the data is not in the preferred format of the addressed receiver, the data is transcoded into a common or raw data format and further transcoded into the preferred data format of the addressed receiver before being optionally encrypted, formatted into a digital packet, and transmitted to the addressed receiver.
