Transform-based methods to transmit the high-definition video

摘要

The present invention presents the HD video transmission methods, which transmit the HD video into transform domain. In an aspect of the present invention, at the HD video transmitter the HD video is transformed by a multi-dimensional transform. Through the discrete-time continuous-valued or quasi-continuous-valued modulation, the obtained coefficients in transform domain are preferably carried in parallel in a multiple-access channel in time-domain to the HD video receiver.

1. A method to transmit video, comprising:
dividing the pixels of the video into one or a plurality of transform blocks; transforming each transform block into a transform coefficient block; mapping the transform coefficients to one or a plurality of to-be-modulated signal frames; and modulating each to-be-modulated signal frame to a transmission signal frame, wherein the video includes but is not limited to one or a plurality of sampled videos whose pixels are continuous-valued or digital videos whose pixels are quasi-continuous-valued, wherein each transform block includes a plurality of pixels of the video, wherein each transform coefficient block includes a plurality of transform coefficients, wherein each to-be-modulated signal frame includes at least one continuous-valued or quasi-continuous-valued transform coefficient, and wherein each transmission signal frame includes a plurality of discrete-time continuous-valued or quasi-continuous-valued samples to be transmitted consecutively over time.
