Gateway apparatus, method, and system
View Patent ↗A gateway receives a predetermined request from a terminal via a network, identifies the type of the terminal, reads a stream or a file, which includes at least one of a video and an audio, from at least one of an equipment connected directly to the gateway and an equipment connected to the gateway via a network, creates conversion information suitable for the type of the terminal, performs conversion for the stream or the file in accordance with the conversion information, and transmits the converted stream or file to the terminal.
1. A gateway apparatus comprising:
a control signal conversion unit that receives a selection result of a content from a server, the server being accessed by a terminal via a network for authentication to select the content,
the control signal conversion unit, on reception of a predetermined request from the terminal via a network that is different from, or the same as, a network on which the gateway apparatus is installed, identifying a type of the terminal to transmit the request including information on the content selected to a home gateway installed in a home via at least the network on which the gateway apparatus is installed;
a reception unit that receives, via the home gateway, a stream or a file, which is the content selected by the terminal, includes at least one of a video and an audio, and is read from at least one of an equipment arranged in the home and connected directly to the home gateway and an equipment arranged in the home and connected to the home gateway via a home network arranged in the home;
a conversion instruction unit that creates conversion information corresponding to the type of the terminal;
a conversion unit that performs conversion for the stream or the file in accordance with the conversion information; and
a transmission unit that transmits the converted stream or file to the terminal via the network that is different from, or the same as, the network on which the gateway apparatus is installed.
2. The gateway apparatus according to claim 1 , wherein the control signal conversion unit, in response to a predetermined request received from the terminal, identifies a type of the terminal and transmits the request to a wireless home gateway via a femto-cell access point provided in a home,
the reception unit receives a stream or a file, which is a content specified by the terminal, includes at least one of a video and an audio, and is read from at least one of an equipment connected directly to the wireless home gateway or a set-top box and an equipment connected to the wireless home gateway or the set-top box via a network, via the wireless home gateway and the femto-cell access point,
the conversion instruction unit creates conversion information corresponding to the type of the terminal, and
the conversion unit performs conversion for the stream or the file in accordance with the conversion information, and
the transmission unit transmits the converted stream or file to the terminal.
3. A network system comprising:
a terminal;
a gateway apparatus according to claim 1 , the gateway being installed on a network;
a home gateway installed in a home; and
an equipment connected directly to the home gateway and/or an equipment connected indirectly to the home gateway via a network, wherein when a predetermined request is received from the terminal via a network that is different from, or the same as, the network.
4. The gateway apparatus according to claim 1 , comprising a table that for each model type of a terminal, holds capability information on the terminal including at least one of
an allowable codec;
a screen resolution;
a frame rate;
a file format and a file size receivable by the terminal; and
a reception protocol of the terminal, wherein
the conversion instruction unit reads the capability information corresponding to the model type of the terminal from the table and creates conversion information corresponding to the capability information.
