In a wireless video transmission method for transmitting a video stream on wireless communication networks, the video stream is classified into at least two classes of sensitivity, each corresponding to a sensitive class of data. Each sensitive class of data is optionally advanced an ahead time for starting transmission based on the corresponding class of sensitivity. Then, an automatic repeat of data is optionally applied on each sensitive class of data based on the corresponding class of sensitivity, thereby providing an enhanced error protective capability and reducing the transmission delay.

1. A wireless video transmission method for transmitting a video stream on wireless communication networks, said video stream including headers, I-frames and P-frames, each of said I-frames and P-frames having discrete cosine transformation coefficients, said method comprising the steps of: (A) classifying said video stream into high sensitive data, medium sensitive data and low sensitive data, said high sensitive data including the headers of said video stream, said medium sensitive data including the discrete cosine transformation coefficients of said I-frames of said video stream; and (B) optionally applying an automatic repeat request scheme on each of the high, medium and low sensitive data based on the sensitivity, wherein sensitive data with a relatively high sensitivity is assigned an automatic repeat request scheme having a relatively high reliability. 2. The wireless video transmission method as claimed in claim 1, further comprising a step (K) executed between step (A) and step (B) for rescheduling said video stream, wherein each of the high, medium and low sensitive data is optionally advanced an ahead time for starting transmission based on the corresponding sensitivity. 3. The wireless video transmission method as claimed in claim 2, wherein in step (B), when said high sensitive data is transmitted, a selective reject automatic repeat request scheme is applied thereon for protecting said video stream against transmission errors. 4. The wireless video transmission method as claimed in claim 2, wherein in step (B), when said medium sensitive data is transmitted, a burst-oriented transfer with a time-bounded retransmission automatic repeat request scheme is applied thereon for protecting said video stream against transmission errors. 5. The wireless video transmission method as claimed in claim 2, wherein in step (B), when said low sensitive data is transmitted, no automatic repeat request scheme is applied thereon. 6. The wireless video transmission method as claimed in claim 2, wherein in step (K), said high sensitive data is advanced a first ahead time for starting transmission, and said medium sensitive data is advanced a second ahead time for starting transmission, so that said video stream is transmitted in a sequence substantially based on the sensitivities. 7. The wireless video transmission method as claimed in claim 2, wherein said video stream is a H.263 video stream.
