Abstract: Prior to communication over the Internet and using a different line, a first terminal transmits to a second terminal a set of information including at least an IP address of the first terminal on the Internet. Based on the IP address thus transmitted separately, the party at the second terminal initiates communication over the Internet. This establishes direct end-to-end communication between the two terminals over the Internet. In a communication setup such as an Internet-based telephone call wherein address information about a desired party on the network is not previously known to a calling party, the inventive method allows the two parties to communicate directly with each other over the network on an end-to-end communication basis without recourse to a rendezvous server or like services.

Abstract: In a telephone apparatus, a modem device, a computer apparatus and a communication terminal device, the connection to different kinds of communication networks is realized with a simple structure.

Abstract: An apparatus for averaging pulses in a stream of pulses, which pulses are categorizable into at least two categories, includes structure for isolating the pulses into groupings of pulses, structure for counting the number of pulses of a particular category that occur within a grouping of pulses, and structure for generating an output signal when a predetermined number of pulses of a particular category occur within a grouping of pulses.

Abstract: An in-circuit emulation capability mode incorporated in an integrated circuit. The in-circuit emulation capability mode disables the microcontroller of the integrated circuit and allows use of an external in-circuit emulator device to test and debug the integrated circuit without the necessity of physically replacing the microcontroller with in-circuit emulator hardware. The in-circuit emulation capability mode is suitable for any integrated circuit, however, it has been found that integrated circuits incorporating an in-circuit emulation capability mode are especially suitable for incorporation into the base and handset units of a cordless telephone that integrates the speech, control channels, and microcontroller portions of a modem, and the man-machine interface functions of a cordless telephone.

Abstract: A method for facilitating communication between parent telephones and child telephones in a cordless telephone system. The method includes steps of dividing a plurality of channels into groups and assigning each parent telephone to one of the groups. When a child telephone is registered with one of the parent telephones, the child telephone may scan only the channels in the group assigned to the parent telephone with which the child telephone is registered, rather than the entire plurality of channels in the cordless telephone system.

Abstract: An integrated circuit especially suitable for incorporation into the base and handset units of a cordless telephone integrates the speech, control channels, and microcontroller portions of a modem, and the man-machine interface functions of a cordless telephone. The integrated circuit includes one or more of a number of aspects including an in-circuit emulation mechanism, a simplified keypad reporting mechanism, advanced noise suppression mechanisms, a low power emergency mode mechanism, a low cost serial control bus, a port pin interrupt mechanism, advanced power saving mechanisms, spectral measurement test mode means, a novel shut down mechanism, and a pull-up disabling mechanism.

Abstract: An I/O port interrupt mechanism includes a source register connected to the port for reporting sources of interrupts arising within the port, an interrupt mask register connected to the source register and operable to configure the I/O port for generation of interrupts, and an interrupt controller connected to the output of the source register and operable to hold off interrupts arising within the I/O port.

Abstract: A serial communication port structure for starting and stopping an internal clock. This internal clock is designed, in operation, to generate a clock output signal to be transmitted to a device external to the system in which the serial communication port is incorporated. By ANDing the clock output signal with a data output signal of predetermined length, the serial communication port can effectively control the passage of time as sensed by the external device.

Abstract: A radio communication apparatus includes a main telephone connected to a digital line network and a plurality of sub telephones each being capable of performing a radio communication to the main telephone. The main telephone includes a memory for storing a subaddress and a direct dial-in number of each of the plurality of sub telephones, and an unit for, upon receiving an incoming signal transmitted from the digital line network, detecting a subaddress or a direct dial-in number included in the incoming signal, discriminating a sub telephone associated with the detected subaddress or direct dial-in number in accordance with the data stored in the memory, and transmitting the incoming signal to the discriminated sub telephone.

Abstract: A method of processing original still picture data representing an original still image and stored in a video memory and storing processed still picture data representing a processed still image in a predetermined location of the video memory comprising the steps of setting an XY orthogonal coordinate system on the video memory, setting a reference line parallel to one of the X and Y axes of the orthogonal coordinate system and passing through a point of intersection of lines, each of which connects corresponding pixels of the original and processed still images, moving multiples the pixel data on a line of the original still image parallel to the reference line and furthest from the reference line to addresses of the video memory forming a line of the processed still image, and repeating the preceding step for pixel data on lines of the still image parallel to the reference line and second furthest from the reference line and succeeding lines, to thereby store the processed still picture data representing th
