Communication device and reconfimethod and apparatus for high definition video wireless transmission
First Claim
1. A high definition video wireless transmission method for transmitting a data packet for a video frame of a high definition video, comprising:
- receiving the video frame;
acquiring a payload length and a Minimum Required Transmission Time related to the video frame, wherein the Minimum Required Transmission Time is a minimum time bound for transmitting the video frame to a receiving end, and the Minimum Required Transmission Time satisfies the requirement of a target frame error rate, wherein the target frame error rate is a frame error rate when displaying the high definition video without a video frame error, and wherein the video frame comprises a video frame size, and the step of acquiring the Minimum Required Transmission Time comprises;
adjusting the payload length and a Modulation and Coding Scheme according to the video frame size and a signal to noise ratio, wherein the Modulation and Coding Scheme is acquired from a conversion table according to the signal to noise ratio;
acquiring the Minimum Required Transmission Time and the payload length according to an equation as follows;

Abstract
A High Definition (HD) video wireless transmission method for transmitting a data packet for a video frame of an HD video is provided. The method includes: receiving the video frame which comprises a video frame size; acquiring a payload length and a Minimal Required Transmission Time (MRTT) associated with the video frame, wherein the MRTT is a minimal time bound for transmitting the video frame to a receiving end; performing partitioning to the video frame for acquiring the data packet according to the payload length; and performing scheduling to the data packet according to the MRTT, and the scheduled data packet is transmitted to the receiving end.
