Abstract: A commodity registration supporting device according to an embodiment includes a receiver, an acquiring section, a first detecting section, an adding section, and an output section. The receiver receives an electromagnetic wave transmitted from a first transmitter provided in a display place where a commodity is displayed. The acquiring section acquires, from the electromagnetic wave received by the receiver, identification information of the commodity displayed in the display place where the first transmitter that transmits the electromagnetic wave is provided. The first detecting section detects a first act of a purchaser taking out the commodity from the display place and storing the commodity in a storage body. The adding section adds, if first act is detected by the first detecting section, the commodity identified by the identification information acquired by the acquiring section to a list. The output section outputs the list.

Abstract: In order that a digital video (DV) camera function as a WWW server in a network, an image capturing section captures an image of a subject. A DV encoder encodes an image signal input from the image capturing section. A recording and playback section plays back DV data recorded in a DV cassette tape. An IP packet assembling/disassembling section assembles a DV signal input from the DV encoder, a DV signal input from the recording and playback section, or an HTML file input from a WWW server processing section into IP packets, and outputs them to an IEEE 1394 interface. The IEEE 1394 interface transmits, via the network, the IP packets input from the IP packet assembling/disassembling section to a personal computer which accessed the DV camera.

Abstract: It becomes possible for a user to set a transmission or reception channel arbitrarily and easily. Each of equipment connected to an IEEE 1394 bus may include a register provided within a RAM 113 to thereby set a transmission or reception default channel. If channels used in the transmission and the reception are not set when the transmission is started, then default channel may be used. When equipment is set to a channel setting mode by operating an operation section 116, a control section 112 may display a channel setting picture on a display section 115. In this state, a user may select a set channel by operating an up-key 116a and a down-key 116b of the operation section 116. Thereafter, when a user operates a “YES” key 116c, the control section 112 may write a selected channel in the above-mentioned register, and ends a default channel setting operation. A user can set the transmission or reception channel arbitrarily and easily.

Abstract: A communication control device includes a determination circuit for determining whether reception of an asynchronous packet from an IEEE 1394 serial bus is allowed or denied by comparing the sum of the size of the asynchronous packet to be received and the size of packets currently stored in a receive FIFO unit with the size of packets which can be stored in the receive FIFO unit. The communication control device further includes an acknowledge generating circuit for generating an acknowledge signal asserting whether reception of the asynchronous packet is allowed or denied based on the determination result of the determination circuit, and the generated acknowledge signal is sent back to the IEEE 1394 serial bus.
