摘要： A video signal input-output circuit and a recording-reproduction apparatus in which a digitally compressed video signal input in packet form can be recorded and reproduced efficiently and in stable fashion. In this apparatus, a clock reference is detected from a packet signal containing the clock reference and a digitally compressed video signal, a time stamp for a packet is generated using a clock signal in phase with the clock reference and added to the particular packet, and the packet signals with the time stamp added thereto are recorded closely to each other in a data storage element such as a magnetic recording medium. At playback, the packet interval is output by being restored to the original length on the basis of the time stamp added to the packet in store.

摘要： An interface is realized that can prevent video signals from being copied easily and which uses a luminance/color difference signal transmission scheme with an excellent harmony with a television circuit. In a video transmission using a digital interface, colorimetry information for defining the conversion from the luminance/color difference signal into a primary color signal and video aspect ratio information are transmitted along with the luminance/color difference type video signal. This allows reproduction of video with high quality and high resolution and also realizes a copyright protection which allows only the users authorized by key information to use the content of the video. With this transmission scheme, it is possible to provide a transmitting apparatus, a receiving apparatus and an interface which highly harmonize with a rationalized television-based circuit.

摘要： By introducing a new copy control system into video signals subjected to picture quality restriction satisfactory only in small-sized PMP displays, a new business model in which copyrighters, consumers and makers can have mutual prosperity is created. “A new copy control rule of prohibiting a video signal output with a picture quality equivalent to that at time of recording from being copied, but permitting a video signal sufficiently degraded in picture quality as compared with time of recording to be copied” is added to the copy-never, copy-one-generation, and copy-free states belonging to the conventional copy control rule. The quality for which the copyrighter can permit copying corresponds to half the current number of DVD pixels. If a quality restricting scheme of thinning out pixels to half compared with time of recording is used, therefore, needs of consumers desiring to enjoy PMPs are satisfied while protecting rights of copyrighters.
摘要翻译：通过将新的复制控制系统引入到仅在小型PMP显示器中令人满意的图像质量限制的视频信号中，创建了一种新的商业模式，其中复印机，消费者和制造商可以相互繁荣。 “与被复制的记录时相同的图像质量的视频信号输出的新的复制控制规则被添加到与要复制的记录的时间相比在图像质量中充分劣化的视频信号” 属于常规复制控制规则的复制永远不会复制一代和无副本状态。复印机可以允许复印的质量对应于当前DVD像素数量的一半。如果使用与记录时间相比减半像素的质量限制方案，则保护想要享受PMP的消费者的需求得到满足，同时保护了复印机的权利。

摘要： A method and apparatus is provided for receiving and/or reproducing a digital signal, capable of efficiently recording a compressed, packeted digital signal and inhibiting a copy thereof. An input packet signal is added with a time stamp indicating a relative time of an arrival of the packet, and the packet signals of digital information with the added time stamps are recorded at reduced intervals therebetween. In reproducing, a packet interval adjusting circuit restores the original packet intervals in accordance with the time stamps, and then a time stamp change circuit changes at least one bit of the time stamp and thereafter outputs the digital information.
