A common interface (CI)/conditional access (CA) module is used to transmit a conditional access data/command and a transport stream in an interleaving manner between a common interface card and an integrated circuit module having a conditional access module. With the aid of the CI/CA module, a same port can be shared for transmitting the conditional access data/command and the transport stream, instead of using two different and separated ports.

Common interface/conditional access module and method of transmitting data between common interface card and integrated circuit chip thereof

An image sharpness device and a method for the same are disclosed. The image sharpness device includes a DC removal unit, at least one filter, at least one noise estimation unit, at least one soft threshold processing unit, and a summing unit. The DC removal unit receives a luminance signal of a field of a frame and removes a DC component of the luminance signal. The filter passes a component of an output of the DC removal unit within a predetermined frequency band. The noise estimation unit estimates a noise value of the field. The soft threshold processing unit forms a sharpness signal according to the noise value. The summing unit sums the luminance signal and the sharpness signal to output a resultant luminance signal. The present invention is capable of avoiding the problem that a noise in the luminance signal is enhanced.
