Object information acquiring apparatus and control method for the object information acquiring apparatus

A digital television which allows a user to view a digital broadcast program designates print information to be printed when making a DTV printer print using program information of the digital broadcast program and the print information supplied together with the program information. The digital television determines whether the print information is a content A supplied from a broadcast station together with the program information or a content B supplied from a WEB server by downloading it from a supply source. If the print information is the content B, the digital television determines whether the print information can be downloaded from the supply source prior to the program broadcasting. A system is thus constructed which can determine whether the print information can be printed when the user reserves printing of the print information.

Digital broadcast reception apparatus and method of printing information contents in the apparatus

An apparatus receives printing structured document data relating to data broadcasting, that has been described in a markup language. The received printing structured document data is parsed, and layout information for printing is extracted. The descriptions relating to printing that are included in the printing structured document data are changed into descriptions which can be parsed by a browser application capable of displaying contents described in a markup language, using the layout information. Thus, when printing data broadcast data in digital broadcasting, a suitable preview display can be made of printing data which has been generated from printing structured document data described in a markup language, using browser functions of a digital TV, before performing printing output of printing data.

Information processing apparatus, control method for information processing apparatus, display apparatus, and control method for display apparatus

A data transmission system where an image providing device and a printer are directly connected by a 1394 serial bus, a command is sent from the image providing device to the printer, then a response to the command is returned from the printer to the image providing device. Image data is sent from the image providing device to the printer based on information included in the response. The printer converts the image data outputted from the image providing device into print data. Thus, printing can be performed without a host computer by directly connecting the image providing device and the printer by the 1394 serial bus or the like.

Data transmission apparatus, system and method, and image processing apparatus

In response to a request from a host device using an initial protocol, capability information including information indicative of a plurality of communication protocols is returned to the host device, and a communication protocol, designated by the host device based on the capability information, is set, and print data is received from the host device by the set communication protocol. In a system using an interface connected to various types of devices, e.g., an IEEE 1394 serial bus, a communication protocol, which is used when a host device transfers print data to a printer, is not limited to that unique to the manufacturer of the device.

Data communication apparatus and method of a device that supports plural communication methods

A device of this invention solely executes a power saving operation without influencing a repeater operation on a serial bus interface to which a plurality of devices are cascade-connected. A device such as a digital camera, printer, or the like, which is cascade-connected using an IEEE1394 serial bus interface, uses an IC prepared by forming both physical and link layers on a single chip. This IC has a port connected to a bus. When a power supply on the bus side is OFF, this port can insulate the bus in DC term. This device transits to a power saving mode such as a sleep mode, suspend mode, shutdown mode, or the like after an elapse of a predetermined wait time. In the shutdown mode, the system power supply of the device is turned off, but the IC can operate by electric power supplied from a cable. With this operation, a signal can be relayed between devices, and a packet for the link layer can be received. Upon receiving a LINK_ON packet, the device is restored from the power saving mode to a normal drive state.

Data processing apparatus and power control method

In a system corresponding to direct printing, even though respective devices have a series of processing functions, high processing performance of the entire system cannot be expected. Accordingly, printing time is longer than that in a system having a personal computer. In a system having a digital camera, a printer and a set top box as a digital broadcast tuner interconnected via a 1394 serial bus, an image processing program necessary for direct printing is downloaded from e.g. the printer to the set top box which lacks an image processing function. Then, time required for data processing on a sample image is calculated at each of processing steps of the image processing, and a device to execute data conversion is determined based on the processing time. By this arrangement, direct printing can be efficiently performed.

Image processing system and control method, and image processing apparatus

In a system where a digital still camerais connected to a printeron a 1394 serial bus, when the digital still cameraas a data transfer originator node transfers image data to the printeras a data transfer destination node, the printersends information on the data processing capability of the printerto the digital still cameraprior to data transfer. The digital still cameradetermines the block size of image data to be transferred in accordance with the data processing capability of the printer, and sends image data of the block size to the printer. The information indicates the capacity of a memory of the printer for storing print data, or the printing capability of a printer engine, i.e., printing resolution, printing speed and the like. Thus, data transfer is always efficiently performed regardless of the data processing capability of the printer
