  • Patent number: 9361258
    Abstract: 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.

  • Patent number: 8760580
    Abstract: 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.

  • Publication number: 20130135432
    Abstract: A device for outputting a chrominance signal and a method thereof are disclosed. The device includes a motion detection unit, a frame edge detection unit, and an output unit. The motion detection unit judges a motion degree of a frame. The frame edge detection unit judges whether a non-3D luminance signal is extracted from an edge of the frame. The output unit outputs one of a 3D chrominance signal and a non-3D chrominance signal as a resultant chrominance signal according to the motion degree which is judged by the motion detection unit and the judgment result of the frame edge detection unit. The present invention is capable of appropriately selecting the 3D chrominance signal and the non-3D chrominance signal when the frame is in the motion condition.

  • Publication number: 20130113998
    Abstract: A device for outputting a luminance signal is disclosed. The device includes a chrominance judgment unit, a field observation unit, and an output unit. The chrominance judgment unit and the field observation unit are used to determine whether a 3D luminance signal is affected. The output unit outputs a resultant luminance signal according to the determination results of the chrominance judgment unit and the field observation unit. According to the present invention, the resultant luminance signal can be accurately obtained by judging characteristics of the 3D luminance signal and a 3D chrominance signal even if a 3D comb filter is wrongly used in a motion condition.

  • Patent number: 8411207
    Abstract: A device for outputting a luminance signal and a method thereof are disclosed. The device includes an image smoothing unit, a band pass filter unit, and a summing unit. The image smoothing unit receives a 2D luminance signal and decreases a signal intensity of a component of the 2D luminance signal within a frequency range with respect to a carrier frequency of a chrominance component. The band pass filter unit passes the component of the 2D luminance signal within the frequency range with respect to the carrier frequency. The summing unit sums the output of the image smoothing unit and the output of the band pass filter unit to generate a resultant luminance signal. The present invention is capable of avoiding the occurrence of saw-tooth or sparkling situation caused by inharmonious switching between a 1D comb filter and a 2D comb filter.
