That is, the key information can be used only to extract the content decryption key for a particular session and for a particular client device such as an audio or video consumer playing device. This prevents any further use or copying of the content other than in that session and for that particular client. The specificity is accomplished by using a device unique identifier and antireplay information which is session specific for encrypting the content key. A typical application is Internet streaming of audio or video to consumers. | 2009-06-18 |

20090154715 | Apparati and methods for sound transduction with minimal interference from background noise and minimal local acoustic radiation - A transducer senses sounds produced by a talker or other source and measures acceleration of air. Enhancement of acceleration is accompanied by reduction of the portion of the sound energy that escapes from the regions around the transducer. The result is a high sensitivity transducer, with increased privacy for use in communication systems, especially cell phones and in a multi-person environment. A pressure sensor array with a weighted output is sensitive to sound from a source talker only, and not to acoustic background noise, and not to a local loudspeaker. The weighted signal is a source sum pressure signal. The array produces a signal (using a different weighting) that corresponds to an estimate of a derivative of pressure. The derivative signal is proportional to the volume velocity fluctuations produced by the source. This signal is enhanced, rather than reduced. A local loudspeaker is driven to make the source sum pressure signal as small as desired. The loudspeaker is driven to produce volume velocity fluctuations approximately equal and opposite to those produced by the source. No compression of air arises due to the talker, and no sound is radiated into the far field. All happens because the system is driven to reduce the source pressure sum signal to below a desired threshold. It is not necessary to directly measure the volume velocity fluctuations of the talker source. | 2009-06-18 |
20090154716 | SYSTEM AND METHOD FOR SOUND SYSTEM SIMULATION - A sound system design/simulation system provides a more realistic simulation of an existing venue by matching a measured reverberation characteristic of the existing venue and adjusting one or more acoustic parameters characterizing the model such that a predicted reverberation characteristic substantially matches the measured reverberation characteristic. | 2009-06-18 |
20090154717 | Echo Suppressing Method and Apparatus | 2009-06-18 |
20090154718 | Method and apparatus for suppressor backfill - In some communication applications, a near-end talker employs a cellular phone that either operates in a noisy environment and does not support artificial noise injection or injects noise but supports a simple, fixed noise injection. This may result in “blanking” of the background noise and result in repeated “are you still there?” questions or premature termination of a call. In order to prevent this feeling of “blanking,” a suppressor backfill module according to an example embodiment of the invention backfills those blank periods with noise, optionally in an inverse relationship with power of noise in a near-end signal, resulting in repairing sound quality degradation and giving a far end talker a feeling of call continuity. As a result, the near-end and far-end talker have a better experience during the call. | 2009-06-18 |
