System and Method for Transferring Data

摘要

A system and a method transmit data in a first codec from a first terminal to a second terminal. The first terminal establishes a connection with the second terminal and/or transmits, transfers and/or sends the data to the second terminal via the connection between the first terminal and the second terminal. The connection between the first terminal and the second terminal has a first channel and/or a second channel to transmit the data from the first terminal to the second terminal. The first terminal transmits the data in a first codec to the second terminal via the first channel and/or the second channel of the connection without receiving capabilities of and/or intentions from the second terminal. The second terminal may be incapable of receiving, of processing, of accepting and/or of displaying the data in the first codec. The capabilities of and/or the intentions from the second terminal is transmitted to the first terminal via the connection. The first terminal switches the data from the first codec to the second codec and/or transmits the data in the second codec to the second terminal via the connection between the first terminal and the second terminal.

1. A system for transmitting data which is at least one of audio signals, video signals and other data signals, the system comprising:
a first terminal connected to a network wherein the first terminal has data encoding capabilities; a second terminal connected to the network wherein the second terminal is remote with respect to the first terminal and further wherein the second terminal has data decoding capabilities; a first codec for encoding the data wherein the first terminal selects the first codec based on the encoding capabilities of the first terminal and further wherein the first terminal encodes the data in the first codec to produce first encoded data wherein the first terminal transmits the first encoded data to the second terminal using the network and further wherein the second terminal receives the first encoded data and determines whether the first encoded data matches the decoding capabilities of the second terminal wherein the second terminal decodes the first encoded data if the first encoded data matches the decoding capabilities of the second terminal and further wherein the second terminal does not decode the first encoded data if the first encoded data does not match the decoding capabilities of the second terminal; a capability description message having the decoding capabilities of the second terminal wherein the capability description message indicates to the first terminal that the second terminal supports the data and the media in the first codec received from the first terminal via a phantom channel wherein the second terminal transmits the capability description message to the first terminal using the network and further wherein the first terminal initiates transmission of the first encoded data before receiving the capability description message; and a predefined digital table accessible to the first terminal and the second terminal prior to communication between the first terminal and the second terminal wherein the predefined digital table has a list of entries and further wherein the entries have an index, a codec, and a configuration description wherein the first terminal identifies the codec and the configuration description associated with the first encoded data by transmitting a corresponding index from the predefined digital table with the first encoded data transmitted to the second terminal.
