Abstract

Disclosed is a multimedia pipeline device including first pipeline circuits and a processor. The first pipeline circuits include: a first circuit generating first data according to input data and recording characteristic information of the input data; and a second circuit generating second data according to the first data and recording characteristic information of the first data. The processor determines whether the characteristic information of the input data and the characteristic information of the first data are correct according to first and second prestored information respectively, in which at least a part of the first prestored information is recorded by the first circuit according to verified input data in advance and at least a part of the second prestored information is recorded by the second circuit according to verified first data in advance, and the verified input data and the input data originate from the same multimedia test file.
