摘要:
A coding apparatus and method for intraframe and interframe coding a digital video signal to produce intraframe coded data and interframe coded data, respectively. The intraframe and interframe coded data are both orthogonally transformed to produce transformed intraframe and interframe coded data. Either the transformed intraframe coded data or the transformed interframe coded data is selected in accordance with respective coefficient data of the intraframe and interframe coded data.
