摘要： 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.

摘要： 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.
摘要翻译：在通过互联网进行通信并使用不同的线路之前，第一终端向因特网上的第一终端的至少IP地址的一组信息发送到第二终端。基于这样分配的IP地址，第二终端的一方通过因特网发起通信。这通过互联网建立两个终端之间的直接端到端通信。在诸如基于因特网的电话呼叫之类的通信设备中，其中关于网络上的期望方的地址信息对于主叫方来说以前不是已知的，本发明的方法允许双方通过网络在一端上直接相互通信无需诉诸于会合服务器或类似服务的端到端通信基础。

摘要： A data processing apparatus constituting a low-cost audio/video data transmission and reception system is disclosed. A reception buffer monitoring circuit 21 monitors the size of receiver data being accumulated in a reception buffer 6. When the size of accumulated data is found to become higher than a high threshold, the circuit 21 causes a reception clock generation circuit 8 to 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 8, an audio/video decoder 7 decodes the audio/video data coming from the reception buffer 6. This invention applies advantageously to a television transmission and reception system for transmitting and receiving TV broadcast signals.

摘要： 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.

摘要： Picture data received in the order of DC components and AC components is stored in a frame memory 115. At this point, an ID number detecting portion 117 detects an ID of a sync block and sends the detected ID to an encoding portion 114. Corresponding to the ID, the encoding portion 114 determines whether or not data that is read from a frame memory 93 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.
