The formation unit is configured to form invalid-image information for an image group containing at least an edit point of edited video content in order to indicate invalid frame images within the image group in accordance with edit point information about the edited video content. The transmission unit is configured to transmit video content via the predetermined network and, if there is invalid-image information formed by the formation unit, transmit the invalid-image information before transmitting the associated image group.

Transmitter, receiver, transmission method, reception method, transmission program, reception program, and video content data structure

Disclosed herein is a recording system including a receiving apparatus and a recording apparatus, wherein the receiving apparatus includes, a creation section, and a reservation control section, the recording apparatus includes, a recording section, and a recording control section.

A network interface unit of a server determines whether the transmission method of transmitting a packet is multicast transmission or unicast transmission; adds to the packet a second FEC when the transmission method of the packets is determined to be multicast transmission and adds to the packet an error detection code for ARQ when the transmission method of the packets is determined to be unicast transmission; and transmits the packet to clients. Each client determines whether the transmission method of the received packet is multicast transmission or unicast transmission; corrects the error on the basis of the second FEC when the transmission method is determined to be multicast transmission; and detects the error on the basis of the error detection code and generates a retransmission request signal when the transmission method is determined to be unicast transmission.

Transmitting device, receiving device, packet transmission method, packet reception method, and programs for same

An electronic apparatus communicable with another electronic apparatus via a network is disclosed. The electronic apparatus may include receiving means for receiving a content recorded on a first recording medium of the other electronic apparatus from the other electronic apparatus, determining means for determining whether the received content is reproducible or irreproducible by decoding the content, and recording means for recording the content on a second recording medium if the content is determined to be reproducible.

Electronic apparatus, content recording method, and program therefor

In order to enable use of both real time access and random access and to achieve improvement of throughput of a communication device and a communication network, a LAN terminal device (), acting as a control station, allocates communication timing corresponding to a communication timing allocation request from a first LAN unit () and a second LAN unit () intending to transmit real time data and notifies each LAN terminal device connected to the same network of information indicating this allocated communication timing. A communication terminal of the requester transmits data through a real time region based on communication timing allocated thereto and random data is transmitted through a random access region.

Communication method, communication system, and communication terminal

A wireless data transmitting and receiving system is disclosed which comprises a server device connected wirelessly to a plurality of client devices constituting a wireless network. The system allows the server device to transmit externally acquired reproduction-destined data to specific client devices in a secure manner.

Wireless data transmitting and receiving system, server device, and server device controlling method

In a communication terminal equipment and in a method of controlling call incoming, unnecessary noises in a period from the start of an alert sound to carrying out of the next operation can be reduced. When a predetermined operation is effected under the condition that an alert sound is ringing, the alert sound is stopped or the volume of the alert sound is reduced at least over a duration of call incoming. Thus, such a fear that persons in the surroundings may be troubled by the continuous ringing of the alert sound can be remarkably reduced. Further, since the situation that a power supply is cut off forcibly during all origination can be avoided, the fear that a person on the call origination side may be given an unpleasant feeling can be eliminated.

Communication terminal equipment and call incoming control method

A radio-network control method selects a channel having a short transmission-waiting time in a radio network which can use a plurality of radio communication channels. Before selecting the channel, the method detects a channel which another radio network is using and a channel having high noise.

Radio-network control apparatus and radio-network control method

In a communication terminal equipment and in a method of controlling call incoming, unnecessary noises in a period from the start of an alert sound to carrying out of the next operation can be reduced. When a predetermined operation is effected under the condition that an alert sound is ringing, the alert sound is stopped or the volume of the alert sound is reduced at least over a duration of call incoming. Thus, such a fear that persons in the surroundings may be troubled by the continuous ringing of the alert sound can be remarkably reduced. Further, since the situation that a power supply is cut off forcibly during call origination can be avoided, the fear that a person on the call origination side may be given an unpleasant feeling can be eliminated.

In a communication terminal device and a method of originating a call, the number of operations at the time of originating a call in a communication terminal device can be reduced. When the send key is depressed for a long period after inputting a numerical sequence by the numeral keys, the call origination based on the input numerical sequence itself is performed. In contrast, when the send key is depressed for a short period after inputting a numerical sequence, the call origination based on the telephone number read from the storage address corresponding to the input numeral sequence is performed. In this manner, the originating operation as to the telephone number stored in the telephone directory memory can be performed by inputting a numeral sequence corresponding to the storage address and depressing the send key, and the originating operation as to an arbitrary special telephone number can be performed merely by inputting a numerical sequence and depressing the send key. Accordingly, the communication terminal device can be obtained which can reduce the number of operations at the time of originating a call and hence provide excellent operability.
