  • Patent number: 8436938
    Abstract: A device is described for receiving data transmitted using asynchronous data transmission technology, in particular audio and video data, which receives a clock signal, having a memory device (17), which stores the received data for the required period of time in order to compensate for transmission delays (Cell Delay Variation). The clock signal is sent to the memory device (17) for reading out the data. Furthermore, a method is described for receiving data signals using asynchronous data transfer technology, with the received data signals being temporarily stored and read out at the studio clock rate.

  • Patent number: 5708686
    Abstract: In a method for receiver-side clock recovery for digital signals having a constant bit rate following cell-structured, asynchronous transmission with pauses of different length between individual cells using the loading state of an FIFO memory into which the received digital signals are written, at the start of a transmission the digital signals are initially read with a received clock into the FIFO memory holding multiple cells of the received signals until the FIFO memory is half filled. The digital signals written into the FIFO memory are read out with a readout clock whose frequency is smaller than the frequency of the received clock. During the readout a signal for controlling the frequency of the readout clock is derived from the respective loading state of the FIFO memory.
