Abstract: 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.

Abstract: 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.

Abstract: The present invention is intended to permit both real-time display of a picture represented by a non-compressed video signal on a television and display of a picture represented by a compressed video signal at any desired time by simultaneously transmitting the compressed video signal and non-compressed video signal via one interface. An STB packetizes a compressed video signal, and multiplexes the compressed video signal and a blanking signal combined with a non-compressed video signal. Thus, both the video signals are transmitted simultaneously. A picture represented by the non-compressed video signal is displayed on a television in real time. The compressed video signal is stored in a storage medium incorporated in the television, read at any user's desired time, and decoded so that a picture represented by the compressed video signal can be viewed at the user's desired time.

Abstract: Various kinds of broadcast TV signals can be watched on display devices at desirable places (rooms). High-frequency signals of CS broadcast, BS broadcast and terrestrial broadcast are received and inputted via a lead wire to a retransmission device. A high-frequency signal of a cable television broadcast is directly inputted to the retransmission device. The retransmission device subsequently converts high-frequency signals of incoming different broadcasts into common high-frequency signals and transmits them in time-series. Then, the common high-frequency signals are transmitted by wired or wireless means to a plurality of display devices that may be installed in different rooms or are portable.

Abstract: In an index signal generator for generating an index signal for use in a direct-drive motor having a rotation axis and comprising a stator and a rotor, a particular at least one of M magnetized elements is used as an index detection magnet having magnetic force which is different from those in remaining ones of the M magnetized elements. Wound around one of a specific one of particular three cores in the stator, an index detection coil detects variations of the magnetic force generated by the ring-shaped permanent magnet to produce a detected signal. On the basis of the detected signal, the index signal is generated.
