20100118873 | Audio Network System - A plurality of partial networks can work independently from each other, and each partial network connects together several nodes including a connection node for transmission of audio signals. A connection network connects respective connection nodes of the respective partial networks so as to connect the plurality of the partial networks with each other through the connection nodes. The connection node of the partial network operates when the audio signal is transmitted from the partial network to the connection network, for forwarding the audio signal from a transmission channel used for carrying the audio signal in the partial network to another transmission channel to be used for carrying the audio signal in the connection network, and operates when the audio signal is transmitted from the connection network to the partial network, for forwarding the audio signal from a transmission channel used for carrying the audio signal in the connection network to another transmission channel to be used for carrying the audio signal in the partial network. | 05-13-2010 |
20100119085 | Audio Signal Processing System - In an audio network system performing real-time transport of audio signals among a series of sequentially connected devices by circulating a TL frame including a plurality of storage regions for the audio signals in a fixed period along a ring transmission route formed among the devices and writing and/or reading the audio signals from/to the TL frame in each of the devices, a mixer of an active system reflecting its processing result in the output and a mixer of a standby system for backup are prepared, so that the mixers perform the same signal processing on waveform data read from the same position of the TL frame and when a switching instruction is issued, the mixer of the standby system reflects its processing result in the output instead of the active system. | 05-13-2010 |
20100150162 | Network System and Audio Signal Processor - In the case of forming an audio network system in which a plurality of processors each having two sets of transmission I/Fs and reception I/Fs are connected and a TL frame generated by a master node and including a plurality of storage regions for audio signals circulates among the processors in each constant period to transport audio signals the among processors, the system is configured such that when a transmitted TL frame does not return to the reception I/F on the forward side but returns to the reception I/F on the backward side in a single mode of transmitting the TL frame to the forward side and circulating the TL frame through one transmission route, the system shifts to a twin mode of transmitting and circulating TL frames through two transmission routes. | 06-17-2010 |
20110022205 | Audio Signal Processing System - Region having a same size in a audio signal region of a transmission frame is allocated to each of an active engine and passive engine. The active engine reads out input signals written into regions of the frame, performs signal processing on the read-out signals, and writes resultant signals into the region allocated to the active engine. The passive engine reads out the input signals written into the regions, performs the same signal processing as the active engine on the read-out signals, and writes resultant output signals into the region allocated to the passive engine. When a flag of the active engine is indicative of a normal state, an output device reads out the output signals from the region allocated to the active engine, but, when the flag is indicative of an abnormal state, the output device reads out the output signals from the region allocated to the passive engine. | 01-27-2011 |
20110033061 | AUDIO SIGNAL PROCESSING DEVICE, AUDIO SIGNAL PROCESSING SYSTEM, AND AUDIO SIGNAL PROCESSING METHOD - An audio signal processing device includes multiple input reception units to which analog audio signals, on which watermark information indicating identification information is superimposed, are input, an extraction unit that is adapted to extract the identification information from each of the analog audio signals input to the multiple input reception units, and a display unit for performing display depending on the identification information extracted by the extraction unit in correspondence with the input reception unit to which the analog audio signal, from which the identification information is extracted, is input, or signal processing unit for performing signal processing depending on the identification information extracted by the extraction unit for the analog audio signal, from which the relevant identification information is extracted, and outputting the processed analog audio signal. | 02-10-2011 |
20110075849 | Network System - A connecting node in a first sub-network system reserves a transmission channel in a connecting network, reads waveform data having a designated signal name from a TL frame in the first sub-network system, and writes the read waveform data into the reserved transmission channel in a TL frame in the connecting network, and a connecting node in a second sub-network system reserves a transmission channel in the second sub-network system, reads the waveform data having the designated signal name from the TL frame in the connecting network, and writes the read waveform data into the reserved transmission channel in a TL frame in the second sub-network system. | 03-31-2011 |

20110083178 | CONTROLLING ACTIVATION OF AN APPLICATION PROGRAM IN AN AUDIO SIGNAL PROCESSING SYSTEM - User operates a selection switch to instruct temporary activation of an application. For the application of which the temporary activation has been instructed, a CPU of a console allocates resources necessary for signal processing by a DSP of an engine and for a parameter editing function of the console. In the DSP, a bypass parameter is set to ON. Thus, there is provided a state capable of accepting various parameter setting operation related to the application, but the signal processing based on the application program is prevented from being started in a substantive manner. In response to a full activation instruction of an application via a full activation instruction switch, the bypass parameter is set to OFF, so that audio signal processing based on the application can be started. In this way, preparatory work for setting parameters related to the application can be performed efficiently. | 04-07-2011 |
20110230989 | AUDIO SIGNAL PROCESSOR AND AUDIO SIGNAL PROCESSING SYSTEM - Even when a system is made to have a configuration in which a plurality of transmission paths are connected to each other, a transmission-impossible time in each transmission path caused by changing a clock source to a device of a different transmission path can be shortened. In an audio signal processing system including first and second networks connected to each other through a bridge device, the bridge device operates as a slave in the first network and as a master in the second network. When the second network is reset, the bridge device starts to operate as a slave in the second network. Then, when continuous reception of an audio transmission frame that another device operating as a master in the second network has transmitted is started, the bridge device resets the first network and starts to operate as a master in the first network. | 09-22-2011 |
