SYSTEM FOR TRANSMITTING TELEVISION PICTURE INFORMATION USING TRANSFORM CODING OF SUBPICTURES |
摘要 |
<p>An error protection code which acts on subpictures together constituting a television picture for the transmission of data for reconstructing the television picture at the receiving end. First each subpicture transformed by, Hadamard functions. Of the coefficients thus formed, a number of most significant coefficient bits which are associated with low frequency transformation functions are protected against a bit error. Moreover, a comparatively small number of coefficient bits within said number are protected against an additional bit error.</p> |
