May 13, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventor Imahama, Yoshiharu (Fukushima, JP), filed on September 30, 2011, was made available online on May 1, 2014.

The assignee for this patent application is D&M Holdings, Inc.

Reporters obtained the following quote from the background information supplied by the inventors: "A network AV system is now in widespread use, which inputs the music accumulated in a media server connected by a network to an individual personal computer or AV equipment via the network and reproduces the music (for example, see Patent Literature 1). In such a network AV system, there is known a network AV receiver device which connects the music input via the network to an AV receiver device without using the personal computer and reproduces the music by the AV receiver.

"Such a network AV system using the conventional media server and network AV receiver device includes the AV receiver device as client equipment which is connected via a local area network (LAN) to a plurality of media servers that accumulate many music files. The AV receiver device as the client equipment requests for the music desired to be reproduced from an arbitrary media server, and in response to this request, the media server transmits the requested music to the client equipment. The client equipment inputs and reproduces the music transmitted from the media server."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "Technical Problem

"In the network AV system using the conventional network AV receiver device, a connection failure of the network may occur due to various causes while inputting and reproducing the music from an arbitrary media server connected to the network. When the connection failure of the network occurs in this way while the network AV receiver device is inputting and reproducing the music from the arbitrary media server, music data cannot be input halfway, and the music being reproduced is suspended.

"The conventional network AV receiver device, as described above, temporarily stores music data corresponding to some extent of time previously downloaded via the network in a storage unit in preparation for the connection failure of the network. Even if the network connection failure occurs, it is known that the reproduction of the music is not suspended due to a few network connection failures by continuously reproducing the music temporarily stored in the storage unit during network connection failure. However, for example, when the network failure or a problem of the server itself occurs in the arbitrary media server itself which is inputting the music, the distribution of the music may be perpetually suspended after occurrence of the connection failure. In this way, when the connection is perpetually suspended from the arbitrary media server which is inputting the music, the network AV receiver device terminates the reproduction of the music temporarily stored in the storage unit, and the reproduction of the music is eventually interrupted halfway.

"It is an object of the present invention to provide a network AV receiver device capable of preventing suspension of the reproduction of the music when the music cannot be input from a media server which is inputting the music in the network AV receiver device that inputs and reproduces the music accumulated in the media server connected to the network.

"Solution to Problem

"According to the invention as claimed in claim 1 of this application, there is provided a network AV receiver device for reproducing music recorded in a media server via a network, the network AV receiver device including: a music information storage unit for storing music information of the music recorded in each media server connected to the network; an input state detection unit for detecting an input state of the media server that inputs the music now being reproduced; and a control unit for controlling an input instruction of the music from the media server, in which, when the input state detection unit detects that an input state of music data now being reproduced is not normal, the control unit switches music data recorded in the media server of the music data now being reproduced to music data recorded in another media server based on the music information of the music recorded in the media server stored in the music information storage unit.

"According to the invention as claimed in claim 2 of this application, in the network AV receiver device according to claim 1, when the input state detection unit detects that the input state of the music data now being reproduced is not normal, the control unit switches the music data to music data having the same music name as a music name of the music data now being reproduced.

"According to the invention as claimed in claim 3 of this application, in the network AV receiver device according to claim 1 or 2, when the input state detection unit detects that the input state of the music data now being reproduced is not normal, the control unit switches the music data to music data having the same tempo as a tempo of the music data now being reproduced.

"According to the invention as claimed in claim 4 of this application, in the network AV receiver device according to claim 2, the control unit switches the music data while controlling to prevent the reproduction of the music data from being interrupted halfway based on a time code of the music data now being reproduced and a time code of the music data having the same music name as the music name of the music being reproduced.

"According to the invention as claimed in claim 5 of this application, in the network AV receiver device according to claim 3, the control unit switches the music data while controlling to fade-out the music now being reproduced and fade-in the music having the same tempo as the tempo of the music being reproduced by matching the temp of the music data being reproduced and the tempo of the music data having the same tempo as the tempo of the music being reproduced based on the tempo of the music data now being reproduced and the tempo of the music data having the same tempo as the tempo of the music being reproduced.

"Advantageous Effects of Invention

"According to the present invention, it is possible to provide the network AV receiver device capable of preventing suspension of the reproduction of the music when the music cannot be input from the media server which is inputting the music in the network AV receiver device that inputs and reproduces the music accumulated in the media server connected to the network.
