Abstract: A device, a method and a program to simplify transcoding of TTS (timestamped transport streams). When transcoding video data in the input TTS, the video processor unit reattaches time stamps in sequence within the applicable frame period of each video frame to each video packet within the applicable video frame after recompression. When transcoding audio data in the input TTS, the audio processor unit reattaches time stamps in sequence within the applicable video frame period of each video frame to each audio packet in the applicable video frame after recompression.

Abstract: A ghost removal apparatus to prevent visual emphasis of image noises when removing ghosts. A transparent characteristic of an image signal is changed with respect to frequency characteristics of ghost removing filters at a frequency of at least 4.2 MHz depending on amounts of noises included in the image signal, and an equalizing characteristic of the image signal is changed with respect to the frequency characteristics of the ghost removing filters at a frequency of at most 4.2 MHz depending on the amounts of the noises.

Abstract: A television receiver has horizontal reducing filter and a vertical reducing filter independently responsive to a first filter control signal and a second filter control signal for reducing auxiliary luminance/chrominance signals indicative of a sub-picture at an arbitrary aspect ratio, and a display unit reproduces a main picture and a reduced auxiliary picture on a screen in an overlapped manner.

Abstract: Digital ghost eliminating filters incorporated in a ghost canceling circuit are responsive to weighted coefficients for canceling ghost components of a digital video signal assigned to a selected channel for a clear video image, and has an auxiliary receiving circuit sequentially tuned in other channels so as to previously produce sets of weighted coefficients for non-selected channels, thereby immediately supplying one of the sets of weighted coefficients to the digital ghost eliminating filters when a main receiving circuit is tuned in another channel.

Abstract: A ghost canceller for cancelling the ghost with dummy ghost signals opposite in characteristics to the ghost signals. Such dummy ghost signals are generated under control of tap gain controls signals and delay control signals generated by analysis of received TV video signals. The filter control circuit in the ghost canceller comprises a standard signal discriminator for discriminating whether the relationship among the subcarrier signal, and the vertical and horizontal synchronizing signals of the input video signal meets the above-mentioned standards or not; and a zero gain signal generator for otherwise setting the tap gain control signal of the ghost cancelling filter to the corresponding value to zero tap gain.In virtue of this construction, the input of nonstandard TV signal unmeet for the standards results in zero tap gain of the transversal filter, and thus the input signal passes, as unaffected, through the ghost filter, and then outputted.

Abstract: A ghost cancelling circuit is provided with a gain limiting block for limiting recursive coefficients for a ghost cancelling filter to a level less than 0 dB in a frequency domain, so that the gains of the recursive coefficients are limited both in the frequency domain and in the time domain. Accordingly, the ghost cancelling filter will never oscillate.

Abstract: A numerical data processor includes first and second registers for receiving and holding input data from a memory, respectively, and a multiplier receiving the input data held in the first and second registers for multiplying the input data held in the first register by the input data held in the second register. A translated address generation circuit is coupled to the memory for generating a translation address of two bits for translation of an address of the input data to be supplied to the register, and an addition/integration circuit receives an output of the multiplier for performing an addition/integration of the output of the multiplier. A controller operates to control the memory, the registers and the translated address generation circuit in a programmed manner so that a Fourier transform, is executed for a given data.
