An event generated in a communication apparatus is sensed. Whether a communication partner apparatus exists in the effective range of a communication unit is detected in accordance with the sensed event. When it is detected that the communication partner apparatus exists in the effective range of the communication unit, application information about an application that operates in the communication partner apparatus is obtained. Activation information including identification information indicating an application to be activated in the communication partner apparatus, and execution information to be executed by the application is transmitted to the communication partner apparatus via the communication unit, based on the obtained application information.

When sequentially receiving pages one by one from the outside and printing them at the time of printing based on printing data including a plurality of pages, a page count per copy when printing a plurality of copies is acquired, and data of a predetermined portion of a printing area are extracted from respective pages by the page count. It is determined whether the data of the extracted predetermined portion is identical between the respective pages. When it is determined that the data is identical, it is determined that printing of the printing data is not collation printing. When it is determined that the data is different, it is determined that printing of the printing data is collation printing.

Printing apparatus for performing printing based on data including a plurality of pages

When a plurality of information signal processing apparatuses are connected via IEEE 1394 communication control buses, these buses are connected via bridges, and bus reset occurs on a remote bus other than connected buses (step S), occurrence of remote bus reset is notified (steps S, S). Thus, even if bus reset occurs, the consistency of bus reset processing in an upper protocol layer can be ensured to realize normal data communication between buses.

An information processing apparatus which makes it easier to carry out setting of a wireless interface necessary for enabling a device or apparatus to be used via the wireless interface, using a wire interface. An information processing apparatus carries out first communication setting so as to enable an apparatus or device to be controlled via a wire interface, communicates with the apparatus or device via the wire interface after the first communication setting to carry out second communication setting for enabling communication with the apparatus or device via a wireless interface. This simplifies the communication setting for enabling communication with the apparatus or device via the wireless interface.

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.

It is an object of this invention to expand an SBP-3 protocol such that two data buffers can be independently controlled. To achieve this object, a target sends responses to status blocks corresponding to two commands included in one ORB in the SBP-3, and an initiator receives these responses to the commands independently of each other. The number of times of execution and time interval are designated for each command. The target repeats a command the designated number of times at the designated time interval.

Notification of completion of communication with a plurality of data storage areas

An IEEE 1394-compliant communication bus connects a printer and host computer so as to allow communication. The configuration ROM of the printer stores information about devices mountable on the apparatus. The host computer accesses the configuration ROM via the communication bus to acquire information in a Feature Directory. The Feature Directory stores information about optional devices connectable to the printer. Information about the printer is displayed based upon information acquired from the Feature Directory. This allows the user to easily grasp information about devices mountable on the apparatus.

An information signal processing apparatus connected to a connection control network, has event reception instrument for receiving a predetermined event instruction irrespective of the type of high level protocol, and when the event reception instrument receives an event instruction, an event corresponding to the received instructionis generated.

Information signal processing apparatus and method

To prevent a command from being unsmoothly issued when a communications channel (LUN) from a conventional initiator to a target enters communications disabled state for any reason there is provided, a data processing method for use between two nodes which are connected to a serial bus and perform communications by a plurality of logical communications units, in which, in the plurality of logical communications units, a first logical communications unit is used in data communications from an initiator to a target, a second logical communications unit is used in data communications from a target to an initiator, and a control command issued from the initiator to the target can be issued to and received by both logical communications units.

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
