  • Patent number: 9185467
    Abstract: A reception apparatus is configured to receive data including a plurality of packets each of which has information on a time point when the packet is generated; to extract a terminal packet which is a packet included in the data received and which has information on a time point which is nearest to a current time point; and to control an operation clock by comparing the information on the time point included in the terminal packet with information on an elapsed time obtained by adding information on a time point, which is included in a terminal packet of preceding data, to an elapsed time from when the preceding data is received to the current time point.

  • Patent number: 8036266
    Abstract: Each of a plurality of encoders calculates a first time by adding an encoding delay time commonly determined between the encoders to a value of an STC counter, and transmits a system stream generated by including the calculated first time to a decoder associated with the encoder in one-to-one correspondence, of a plurality of decoders constituting a decoding system. Each of the decoders calculates a second time by adding the first time to an estimated maximum value commonly determined between the decoders by adding a decoding delay time to a value of stream fluctuation of an output time occurring between the encoders, and outputs the divided image data decoded from the system stream to a synthesizer that synthesizes the image data at the calculated second time.

  • Publication number: 20050190697
    Abstract: A transmission apparatus unitizes a plurality of variable-length frames in units of predetermined size and sorts the unitized frames for each unit into each of a plurality of ports, thereby transmitting the sorted frames. A reception apparatus accumulates received frames in each port and collects the accumulated frames for each unit from each port.

  • Patent number: 6490003
    Abstract: A video signal processing apparatus includes a receiver receiving an incoming video signal and producing an output video signal in response thereto, a limit setup unit setting up at least one of an upper limit value and a lower limit value for the output video signal, and a limiter supplied with the output video signal from the receiver and further with at least one of the upper limit value and the lower limit value from the limit setup unit, wherein the limiter limits a level of the output video signal produced by the receiver, by comparing the level of the output video signal according to any of the upper limit value and the lower limit value.
