摘要： A video data transfer control system allowing secure protection of video data from unauthorized copying is disclosed. A scrambling key used to scramble video data is stored in a key register and a new scrambling key is stored in a register. At the timing of a vertical sync signal of the video data, the scrambling key is changed to the new one. As a result, the scrambling key can be frequently changed while transferring the video data, achieving enhanced protection of the video data from unauthorized copying.

摘要： An image size changing apparatus has a relatively smaller circuitry arrangement for producing a size changed image which exhibits minimum artifacts such as foldover. The image size changing apparatus of the present invention allows image data to be interpolated with a ratio between a visual area determined by pixel data DS0, DS1, and DS2 of an original image and a visual area determined by pixel data DD0 and DD1 of its size changed image, hence yielding the size changed image with less artifacts such as foldover in its relatively smaller circuitry arrangement.

摘要： A digital broadcast receiver capable of simultaneously inputting packet data of a plurality of channels which may have the same ID is disclosed. A converter converts the PID of stream data inputted from a demodulator into unique PID. The stream data converted by the converter and stream data inputted from another demodulator are multiplexed to a single stream of data. The single stream of data is divided into to-be-decoded packets, first packets having converted PIDs, and second packets inputted from the other demodulator. The converted PID of a first packet is converted to the original PID. The first packets and second packets outputted by the stream divider are separately stored in a memory.

摘要： A PCI function extension control circuit 1 monitors the transaction of a first PCI bus and a second PCI bus and makes a bus switch emit an open and close control signal when it concerns an access to a desired configuration area. The bus switch disconnects or connect the PCI bus 101 and the PCI bus 102 upon the reception of the open and close control signal from the PCI function extension control circuit 1. The PCI function extension control circuit 1 outputs a desired PCI control signal to the first PCI bus, or the second PCI bus.

摘要： An effective video interval detector detects an effective video interval of a digital video signal from an A/D converter, and outputs differential data indicative of the difference between the detected effective video interval and a required video data interval. A video signal supply interval controller produces frequency-dividing ratio control data depending on the differential data supplied thereto and supplies the frequency-dividing ratio control data to a programmable frequency divider to vary its frequency-dividing ratio. An output signal frequency from a voltage-controlled oscillator is now controlled to eliminate the difference between the effective video interval and the required video data interval. Even when a video signal supplying device is connected to a video signal source which produces a video signal having a different horizontal synchronizing frequency, the output signal frequency from the voltage-controlled oscillator can be brought into synchronism with the horizontal scanning frequency of the video signal from the video signal source for thereby enabling the A/D converter to sample the effective video interval in a desired number of samples.
摘要翻译：有效视频间隔检测器检测来自A / D转换器的数字视频信号的有效视频间隔，并且输出表示检测到的有效视频间隔与所需视频数据间隔之间的差的差分数据。视频信号供给间隔控制器根据提供给其的差分数据产生分频比控制数据，并将分频比控制数据提供给可编程分频器以改变其分频比。现在控制来自压控振荡器的输出信号频率以消除有效视频间隔与所需视频数据间隔之间的差异。即使当视频信号提供装置连接到产生具有不同水平同步频率的视频信号的视频信号源时，来自压控振荡器的输出信号频率也可以与视频信号的水平扫描频率同步从而使A / D转换器能够以期望数量的样本对有效视频间隔进行采样。
