An apparatus, method and a computer program for processing multimedia data is described, where the apparatus may include an input switch which may receive a plurality of transport stream packets corresponding to a plurality of digital multimedia data signals input thereto, and a packet identification (PID) filter unit which may selectively output a given set of TS packets to be demultiplexed from the received plurality of TS packets. A buffer and/or an external memory device may store at least some of the TS packets of the output given set. A conditional access/content protection (CA/CP) unit may read and decrypt the TS packets stored in the buffer, and may encrypt at least some of the decrypted TS packets for storage in the external memory device if the buffer becomes full, to prevent the TS packets to be stored in the external memory device from being copied.

Method, apparatus and computer program for processing multimedia data signals

An exemplary embodiment of the present invention may provide an arbiter, a demultiplexer, and a digital receiver. An exemplary embodiment of the demultiplexer may include packet identifier filters, first-in first-out memories, an arbiter, and a conditional access buffer. Another exemplary embodiment of the present invention provides a method for demultiplexing multiplexed broadcasting signals.

Demultiplexer and demultiplexing methods for digital broadcasting receiver

A method and apparatus for calculating an observation probability includes a first operation unit that subtracts a mean of a first plurality of parameters of an input voice signal from a second parameter of an input voice signal, and multiplies the subtraction result to obtain a first output. The first output is squared and accumulated N times in a second operation unit to obtain a second output. A third operation unit subtracts a given weighted value from the second output to obtain a third output, and a comparator stores the third output for a comparator stores the third output in order to extract L outputs therefrom, and stores the L extracted outputs based on an order of magnitude of the extracted L outputs.
