The invention provides an equipment for realizing content filtering of simulating multimedia broadcasting, comprising a multimedia signal input circuit, a tuning circuit, a signal storage delay circuit, wherein the multimedia signal input circuit receives digital multimedia broadcasting signals; the output of the multimedia signal input circuit is connected with the tuning circuit; the output of the tuning circuit is connected with the signal storage delay circuit; the signal storage delay circuit digitalizes the multimedia input signals output by the tuning circuit into multimedia data and stores the multimedia data in a storage; and when reaching a certain capacity, the stored multimedia data is read and is synthesized into multimedia signals which are then output, and the multimedia input signals are digitalized into multimedia data continuously in the output process of multimedia signals and are stored in the storage. The equipment realizes that a receiver filters unneeded contentaccording to own preference under the demand of minimum delay time and minimum storage capacity so as to improve receiving experience of the receiver.
