Abstract: An input switching device is provided that includes an output decision device, an input switching device, and a switching command device. The output decision device is connected to an input component and configured to determine whether an external device is ready to output a signal to the input component. The input switching device is arranged between the input and an output component. The input switching device switches to the input component when the output decision device has determined that the external device is ready to output a signal to the input component. The switching command device is arranged between the output decision device and the input switching device. The switching command device is configured to instruct a video display device to receive a signal from the input switching device when the output decision device has determined that the external device is ready to output a signal to the input component.

Abstract: The present invention provides a reproduction apparatus capable of automatically switching an input of a television to an output from a broadcast receiver such as an STB. A television, upon receiving a notification command notifying that output of video or audio is to start, switches its input to an output from an apparatus which has sent the notification command. An STB, upon receiving an instruction command instructing that output of video or audio should be started, sends the notification command to the television. A DVD recorder includes: a decoder that reproduces video or audio recorded in a DVD-RAM disc; a data output I/F that outputs the reproduced video or audio to the television; and a command sending and receiving I/F that sends the instruction command to the STB when the output of the reproduced video or audio ends.

Abstract: The network system comprises an original device description indicating a control point so as to register an address used for MAC address authentication. The server side acquires information from the device(s) connected to the network, and only the device(s) having the above mentioned description are listed and displayed. By responding to the access from the non-registered device in a predetermined manner, the device is prompted to be registered.

The digital broadcast receiving apparatus includes: a broadcast receiving unit receiving a digital broadcast; an extraction unit extracting a service description table from the received digital broadcast; an identification unit identifying, from the extracted service description table, transport stream identification information, network identification information, and service identification information, as stream identification information; and a transmission unit transmitting, to a recording apparatus, the identified stream identification information and a recording command.

Abstract: A television set includes: an internal speaker which outputs sound; a memory which holds information; a remote controller receiver which receives an instruction from the outside of the television set; a microcomputer which causes, based on a mode specifying instruction for specifying a sound output mode received by the remote controller receiver, the memory to hold any one of (a) information that indicates a first sound output mode in which sound is outputted from the internal speaker and (b) information that indicates a second sound output mode in which sound is outputted from an external speaker that is a speaker outside the television set; and an HDMI/CEC communication unit which outputs the information that indicates the sound output mode and that is held by the memory, to an amplifier which controls to operate or not operate the speaker outside the television set.

Abstract: An output control apparatus capable of appropriately switching screens depending on a current situation, and a reproduction apparatus and a television performing the same. The television includes a tuner receiving a television broadcast, a data input I/F receiving video or audio from a DVD recorder, and a command input I/F receiving a command from the DVD recorder. Further, the television includes a user input unit receiving an instruction from a user, a switch selecting the tuner or the data input I/F, an output processing unit controlling an output of video or audio from the switch, and a control unit (i) switching the switch to the tuner when the switch selects the data input I/F when a first command is inputted from the command input I/F and (ii) not switching the switch when the switch does not select the data input I/F.

Abstract: A sound reproduction apparatus of the present application stores the physical address value of a source device that is the device to be switched to, and references the physical address values that are parameters of CEC commands issued by other devices. In the case where the referenced physical address value matches the stored physical address value of the source device, the sound reproduction apparatus automatically switches the sound input to the sound input for the device to be switched to. In this manner, the sound reproduction apparatus can reproduce sound based on a multichannel sound signal output from the source device. Also, in the case where a user sets the source device to a viewing state through a sink device, the sound reproduction apparatus automatically switches the sound input to the sound input from the source device.

Abstract: When the HPD (104b) which indicated that the transmission of a control signal between the data receiving apparatus (102) and the control signal receiving apparatus (101) has become possible is detected, the command judging section (115) ignores the first reception command which it directly received from the remote controller (103) and makes the second reception command (112a) effective which it receives via the CEC line (104a). In such a construction, it is possible to conduct a remote control operation normally without affecting unfavorable influences on the apparatuses.
