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： 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： It is a task of this invention to create a novel system (ubiquitous movie) that brings benefits to both a copyright holder of video information such as movies and general consumers who want to enjoy viewing the video information.As for high image quality video information that the copyright holder wants to keep in a copy prohibited condition or the like, a copyright control such as copy prohibited condition is performed as is done with DVDs. In addition to the high image quality video information, a medium is recorded with another piece of video information whose image quality is limited to less than half the resolution of the high image quality video information, at which level the copyright holder can afford to permit the video information to be copied. This low image quality video information is attached with copyright protection information allowing copy, move and download operations as it is recorded in the medium. From this video information-recorded medium, the video information with the limited resolution is read out and recorded in a small medium that is easy to handle outdoors. The small medium containing the video information with the limited resolution is played in a video player that has a small display showing the played back video information.

摘要： In a digital information recording and reproducing apparatus of a rotary magnetic head type for selecting and recording a plurality of digital information signals having different transmission rates and for selectively reproducing the recorded signal, a high-rate digital information signal and a low-rate digital information signal are inputted for selection of either one thereof to be converted by a recording-system encoder into two channels of recording signals. When recording the high-rate signal, the rotary drum is turned at a rotation speed and the magnetic tape is fed at a feed speed (V1) to conduct 4-track azimuth recording of the signals for each rotation of the rotary drum by the first to fourth magnetic heads. To record the low-rate signal, the rotary drum is turned at a rotation speed substantially equal to the first rotation speed and the magnetic tape is fed at a feed speed almost equal to (V1/N) so as to achieve 4-track azimuth recording of record signals compressed on a time axis to 1/N of the original signals for every N rotations of the rotary drum by the magnetic heads. A reproducing system receives two channels of signals reproduced by the first to fourth magnetic heads and conducts for the signals such processes reverse to those of the encoding process of the recording system.
