    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: 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.
