Embodiment Construction
[0048] Referring to the accompanying drawings, a wireless transmission method for uncompressed high-definition video signals based on wavelet transform characteristics of the present invention includes:
[0049] It includes the following steps:
[0050] a. At the transmitter, such as figure 1 As shown, the source-channel joint encoding module 2 connected with the video source device 1 reads the original image frame from the video source device 1, and buffers in the buffer of the source-channel joint encoding module 2 in the mode of pixel;
[0051] b. The source-channel joint coding module 2 at the transmitting end performs wavelet transform processing on the original digital video image from the video source device 1 buffered in the buffer in the source-channel joint coding module 2 to obtain wavelet coefficients (such as figure 2 The described wavelet transform processing is to adopt the lifting wavelet transform algorithm that is easy to realize by hardware, through the fo...
