  • Patent number: 7965978
    Abstract: A transmitting/receiving method that can easily detect an influence exerted in transmission channels at a transmitter/receiver is provided. An acquiring unit 12 acquires left audio data and right audio data of audio data received by a metadata calculator 1. An adding unit 141 then calculates added data based on an added value for a predetermined time of a sum of the acquired left audio data and right audio data. Similarly, a subtracting unit 142 calculates subtracted data based on an added value for predetermined time of a difference between the acquired right audio data and left audio data. An addition unit 17 adds the added data and the subtracted data calculated by these adding unit 141 and subtracting unit 142 to the received audio data, and a transmission unit 18 transmits the audio data to which the added data and the subtracted data are added.

  • Patent number: 7966029
    Abstract: Push-to-talk private call pre-emption may be applied in an application-to-person context or on a person-to-person context. A PTT subscriber may send a PTT server a pre-emption request indicating a desire to interrupt the application voice stream or another PTT subscriber, respectively. In an application-to-person context, the PTT server may revoke the floor from the application server and grant the floor to the requesting device. In a person-to-person context, the PTT server may send the other PTT subscriber a floor release request. Once the subscriber with the PTT floor releases it in response to the floor release request, the PTT server will be able to send an open floor signal back to the requesting subscriber.
