Abstract: An apparatus and method for wireless transmission of uncompressed HDTV video overcomes the challenges of sending vast amounts of information over a wireless link. This is achieved by direct mapping of transformation coefficients of the video components to communication symbols, such as OFDM symbols. A main portion of the important transform coefficients, for example the MSBs of the coefficients representing lower frequencies of each of the video components, and in particular the quantized values of the lower frequencies components, are sent in a coarse representation using, for example, QPSK or QAM. The coefficients representing higher frequencies of the video components, and the quantization error values of the lower frequencies components, or some, non-linear transformation thereof, are sent as pairs of real and imaginary portions of a complex number that comprises a point in a fine constellation. The invention further provides a delay-less and buffer-less implementation of transmitter and receiver pairs.

Abstract: The vertical blanking period is an idle period in video transmission that was originally intended for allowing the trace back of an electron beam to its point of origin. When sending the video signal over a wireless channel, the wireless channel may remain free of transmission of data during this period. However, in wireless transmission of a video signal in general, and in the transmission of an essentially uncompressed video signal in particular, there is a need to use all the bandwidth available, especially when transmitting a high-definition video signal. Therefore, a method is taught for using the vertical blanking period of a video signal for modem maintenance.

Abstract: Wireless transmission of high-definition video, whether essentially uncompressed or compressed, is prone to errors during reception due to the condition of the wireless link. To ensure video quality during changing link conditions it is desirable to ensure that those portions of the video that represent the more important components of the video signal, such as the lower special frequencies or most significant bits, are assured correct reception at the receiver. Bandwidth limitations of the wireless link affect the amount of data that can be sent over the link. Hence, using a high level error recovery for all of the information is not feasible. Accordingly, a method and apparatus for unequal error protection is disclosed that provides a higher level of error protection to the more important elements of the transmission while affording less error protection to the other elements of the transmission.
