摘要： PROBLEM TO BE SOLVED: To provide an audio signal processing method for improving the output quality of an audio signal to be transmitted to a subscriber's terminal via a communication network and an audio signal processing device adopting the method.SOLUTION: Provided are an audio signal processing method for preventing sound quality deterioration of an audio signal to be transmitted to a subscriber's terminal and an audio signal processing device adopting the method, by enabling a codec module, which codes the audio signal by processing the audio signal to be transmitted to the subscriber's terminal via a communication network, to identify the audio signal as a voice signal. The present invention can enhance the probability that the codec module identifies the audio signal as the voice signal when the audio signal is transmitted via the communication network, by preprocessing the audio signal to be transmitted via the communication network by using an audio codec.

摘要： PROBLEM TO BE SOLVED: To provide a content recommendation.SOLUTION: A server 2 transmits a first content recommendation list responding to a request in accordance with a user feedback profile. A client 3 generates a user feedback concerning each of items included in the list to transmit corresponding user feedback information to the server. Responding to an entry selection from the first content recommendation list, a second recommendation list request is transmitted to the server to provide a visual expression of the first content recommendation list entry. Receiving the user feedback information, the server generates a second content recommendation list based on the user feedback information to transmit the same responding to the second recommendation list request to provide a visual expression of the second content recommendation list entry responding to a selection. The server starts transmission processing of at least one of content items based on the selection and prepares the second content recommendation list before receiving a second recommendation list request.
