Abstract
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.
Claims7
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.
