Abstract:
Apparatus for encoding video data representing an image, comprising:a video encoder for receiving said video data, said video encoder compressing said video data using a compression algorithm having a bi-orthogonal (7,9) wavelet transform to generate compressed video data;a random access memory connected to said video encoder, said random access memory operating as a temporary storage device for storing said compressed video data whenever said video encoder is compressing said video data;a digital signal processor connected to said video encoder, said digital signal processor monitoring a data flow rate of said compressed video data from said video encoder, said digital signal processor adjusting compression ratios for said video encoder to maintain a constant data flow rate of said compressed video data from said video encoder; anda programmed gate array connected to said video encoder to receive said compressed video data, said programmed gate array converting said compressed video data from a parallel format to a serial format for transmission to an external processor, said programmed gate array maintaining a constant serial data flow rate of said compressed video data to said external processor.
