| titleOfInvention |
System for compressing video data using bi-orthogonal wavelet coding having a DSP for adjusting compression ratios to maintain a constant data flow rate of the compressed data |
| abstract |
An encoder for compressing video data to allow for its transmission over a narrow bandwidth. The encoder comprises a multiformat video codec for real-time compression digital data and a dynamic random access memory which operates as a temporary storage device storing compressed data while the codec is compressing data. A digital signal processor adjust the data compression ratio for the codec while the codec is compressing video data. An EPROM, which is connected to the digital signal processor contains the software to run the digital signal processor. A programmable gate array operates as an interface between the codec and an external processor. The array includes a read write controller which provides a read signal to the codec to allow compressed video data to be read from the codec to a parallel to serial shift register within the array. The write control signals which allow data to be written into and shifted through the register are also generated by the read write controller. The array includes a FIFO flush data controller which is used to flush data from a FIFO within the codec whenever the codec supplies a service request signal to the programmable gate array. The service request signal is provided to the array whenever an overflow condition is about to occur within the FIFO of the codec. |
