The present invention provides a transmission/reception apparatus capable of achieving both a high processing speed and good extensibility in performing communication protocol processes. Used for transmitting data in accordance with a predetermined communication protocol and receiving data transmitted in accordance with the predetermined communication protocol, the transmission/reception apparatus has a configuration capable of executing communication protocol processes by using hardware (in first and second communication-protocol-processing units) and software (in first and second control units). The hardware or the software can be selected properly in accordance with the type of data. For example, a communication protocol process for data regarded as a heavy processing load can be carried out by using the hardware at the high processing speed whereas a communication protocol process for data regarded as a light processing load can be carried out by using the software, which offers the good extensibility.

Transmission apparatus, reception apparatus and transmission/reception apparatus for image and/or audio data and other than image and/or audio data

A data processing apparatus constitutes a low-cost audio/video data transmission and reception system. A reception buffer monitoring circuitmonitors the size of receiver data being accumulated in a reception buffer. When the size of accumulated data is found to become higher than a high threshold, the circuitcauses a reception clock generation circuitto generate a reception clock with a higher frequency. When the accumulated data size becomes lower than a low threshold, the reception clock is generated with a lower frequency. Based on the reception clock fed from the reception clock generation circuit, an audio/video decoderdecodes the audio/video data coming from the reception buffer. The data processing apparatus applies advantageously to a television transmission and reception system for transmitting and receiving TV broadcast signals.

Data processing apparatus which prevents data overflow and underflow

A television reception system is disclosed by which a television broadcasting program can be enjoyed at any place in a home without being influenced by connection to an antenna cable or a communication circuit and which can be connected to a network such as the Internet. A channel selection apparatus and a display apparatus are formed as separate apparatus from each other. The channel selection apparatus receives broadcasting signals, selects one of the broadcasting signals, forms a transmission signal from the selected broadcasting signal and transmits the transmission signal by radio. The radio signal from the channel selection apparatus is received by the display apparatus, and an image based on an image signal of the received signal is displayed on an LCD apparatus serving as a display element.

Television reception system, channel selection apparatus and display apparatus

A communication system, method and apparatus which can maintain favorable communication quality without imposing much burden upon a user. A plurality of communication networks are formed between first and second communication apparatus. Upon starting communication between the first and second apparatus, communication quality of the communication networks is measured using at least one of the communication apparatus. One of the communication apparatus is selected for communication based on a result of the measurement. The first and second apparatus may be a base apparatus and a portable terminal apparatus, respectively, for use in the home, in which the base apparatus receives a television broadcast and transmits a selected television program of the broadcast to the terminal apparatus for display thereon. The communication networks may include a radio network and a wireline network. The terminal apparatus may also be adapted to access the Internet via the base apparatus.

Communication system, apparatus and methods employing multiple communication networks

A data processing apparatus constituting a low-cost audio/video data transmission and reception system is disclosed. A reception buffer monitoring circuitmonitors the size of receiver data being accumulated in a reception buffer. When the size of accumulated data is found to become higher than a high threshold, the circuitcauses a reception clock generation circuitto generate a reception clock with a higher frequency. When the accumulated data size becomes lower than a low threshold, the reception clock is generated with a lower frequency.

Data processor capable of preventing data overflows and underflows

An information processing method and apparatus for enabling more prompt sign-up. A network management server at step Sreceived am equipment serial number from an information processing apparatus and, at step s, references a database to retrieve a received equipment serial number. If the equipment serial number has not been found, the program moves to step Swhere a command for initiating manual setting is sent to an information processing apparatus. If the equipment serial number has been found, the program moves to step Sto verify whether or not the admittance made or admittance not as yet made, recorded in the database in association with the equipment serial number received is admittance made. If the verified result indicates admittance not as yet made, the program moves to step Swhere the network management server sends an automatic setting initiating command to the information processing apparatus.

Picture data received in the order of DC components and AC components is stored in a frame memory,At this point, an ID number detecting portion,detects an ID of a sync block and sends the detected ID to an encoding portion,Corresponding to the ID, the encoding portion,determines whether or not data that is read from a frame memory,is a buffering unit that has been stored. Thus, when the read data is the buffering unit, the read data is output as it is. When the read data is not the buffering unit, gray data is output.

Wireless communication system, fixed station device and mobile station device

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.

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.
