An apparatus may include a control unit to determine whether a display state notification indicating a dimensional display process exists. The control unit may set an output form of display data to be displayed on image data to an output form corresponding to a display state indicated by the display state notification.

Image data transmission apparatus, image data transmission method, image data reception apparatus, image data reception method, and image data transmission and reception system

A broadcasting data receiving apparatus which can receive broadcasting data and update software by using software update data received as the broadcasting data includes a receiving portion operable to receive broadcasting data, a video/audio processing portion operable to process video data included in the received broadcasting data for video display and audio data included in the received broadcasting data for audio output based on stored software, an operation input portion operable to receive a user operation, and a control portion operable to (i) control the processing in the video/audio processing portion, (ii) perform software update processing on a necessary component by using received software update data if the received broadcasting data includes the software update data, and (iii) perform minimal display processing or minimal audio output processing in the video/audio processing portion if the operation input portion receives a user operation to start the apparatus during execution of the update processing.

Broadcasting data receiving apparatus

When a signal path in a signal outputting device is changed, the signal outputting device indicates signal path change information representing the change in the signal path to a signal inputting device. Based on the signal path change information, the signal inputting device adaptively changes a signal path between the signal outputting device and the signal inputting device. The signal inputting device can know the signal path in the signal outputting device easier than heretofore, and can simply change the signal path between the signal outputting device and the signal inputting device.

Signal processing system, signal outputting device, signal inputting device, and communication control method

The present invention relates to a signal processing system, and proposes the switching operation of device selection which is naturally performed for a user. The signal input devicecomprises a registration means for registering the signal output devices, and an establishment means for, when an establishment request signal requesting the establishment of a signal path is sent from any signal output deviceout of a plurality of the signal output devices, judging whether the signal output device, which sent the establishment request signal, is registered in the signal input device, and establishing the signal path between the signal output deviceand the signal input devicedepending on the judged result, thereby avoiding unnatural operation which is not performed in accordance with user operation, thus making it possible to perform the switching operation of device selection which is naturally performed for a user.

Signal processing system, signal receiving device, and communication control method

A communication controlling system which permits plural broadcast programs from plural broadcast program providers to be viewed easily and inexpensively. For a case wherein plural broadcast signals containing a hierarchy in need of differential scrambling and a hierarchy that permits common demodulation, encoding or demultiplexing are transmitted/received on a bus , the system includes signal processing devices to for performing descrambling and a reception device for performing common processing, such as demodulation, encoding and demultiplexing. The bus is the IEEE1394 bus, so that, if any one of plural broadcast programs is designated, the signal processing device corresponding to the designated broadcast signals can be automatically set by the control node on the bus , at the same time as a path used for transmitting/receiving signals between the reception device and the signal processing device as set can be set or cancelled.

Communication controlling method, communication controlling system and communication controlling apparatus

An object of this invention is to enable a lock transaction to be carried out between apparatuses connected through a bus such as IEEE 1394 method with fewer data transmission processings. If a register conditionally writable is mounted on a desired apparatus connected through the serial communication bus, when it is intended to write into an apparatus having this register through the bus from other apparatus, a value estimated to be written in the register is obtained by a predetermined processing and then, that value and a value desired to be written into the register are instructed directly so as to control the write into the register.

Communication method, communication apparatus, communication system and providing medium

An information processing apparatus having unique information connected to a network together with a plurality of other information processing apparatuses each connected to the network and each having unique information is provided. The apparatus receives unique information for identifying all of the information processing apparatuses on the network, and obtains a network structure of the network based upon the unique information of all of the information processing apparatuses. The apparatus counts a number of connections between all of the information processing apparatuses on the network based upon the network structure, and controls the communication timing of the information apparatuses on the network based upon the number of connections. The apparatus obtains a topology map of the network based upon the unique information of each of the information processing apparatuses. The apparatus stores the topology map, stores the appropriate timings corresponding to number of the connections, and controls the communication timing.
