Patent ID: 7561933

Claim:
An apparatus for processing an audio signal to be reproduced in a terminal connected to a network, the apparatus comprising; an input unit that receives the audio signal; a signal processing unit that receives at least one of network information and terminal information, and processes the audio signal received from the input unit using signal information and at least one of the received network information and the received terminal information; and an output unit that streams the processed audio signal, wherein the network information refers to information regarding the network, the status of the network being variable at any time, the terminal information refers to information regarding the terminal, the status of the terminal being variable at any time, and the signal information refers to information on the audio signal; wherein the signal processing unit includes a process determining unit that determines a process to be applied to the audio signal, among a number-of-channels adjusting process, a data selecting process, and a band reducing process, according to at least one of the network information and the terminal information, and a main processing unit. wherein the process determining unit includes a process selecting portion that selects the type of a process to be applied to the audio signal from among the number-of-channels adjusting process, the data selecting process, and the band reducing process using a table that maps at least one of the network information and the terminal information to at least one of the number-of-channels adjusting process, the data selecting process, and the band reducing process, and wherein the process determining unit further comprises a table generating portion that generates the table using at least one of the network information and the terminal information and the audio signal received from the input unit and outputs the generated table to the process selecting portion.
