摘要： A recording system (300) that enables single authorized recordings of protected broadcasts to be made. Subsequent unauthorized copies are prohibited by encoding a signal that causes the broadcast to be obscured during playback of the unauthorized copies (220). A broadcast is encoded to indicate that a single copy is authorized (250). If a copy is authorized, a control signal is input to the recording device wherein the signal is conditioned for recording, and prior to placement of the conditioned signal on the recording medium, the copy protect signal is encoded. Thus, if a second copy (which is unauthorized) is made, the copy protect signal will cause the recorded second copy to be obscured making the copy of little value to the unauthorized copier (235).
摘要翻译：一种能够进行受保护广播的单一授权记录的记录系统（300）。通过编码在播放未经授权的副本（220）期间导致广播被遮蔽的信号被禁止后续的未授权复制。广播被编码以指示单个副本被授权（250）。如果副本被授权，则将控制信号输入到记录装置，其中信号被调节用于记录，并且在将经调节的信号放置在记录介质之前，对复制保护信号进行编码。因此，如果进行了第二副本（未经授权），则复制保护信号将导致所记录的第二副本被遮蔽，使得对未授权的复印机（235）没有价值的副本。

摘要： An apparatus and method for post-processing image data which previously was encoded using a discrete cosine transform in order to remove resulting blocking effects. Correction coefficients are generated by determining the least mean square error of the blocking error. The correction coefficients are adjusted to be within the quantization range of the quantization step size used during the coding process. The adjusted correction coefficients are then used to generate the correction terms which are subsequently combined with the original image data to generate an image exhibiting reduced blocking effects when the image is displayed.

摘要： A device for recording digital picture signals has a circuit for converting the input digital picture signals into blocks of data comprising a plurality of picture element data, an encoding circuit which encodes the output of the converting circuit in compressed data for every block, and a channel-encoding circuit which channel-encodes the encoded data outputted from the encoding circuit. The data outputted from the channel-encoding circuit is recorded on a magnetic tape by magnetic heads installed on a rotating drum. In the device, the pitch of the tracks formed on the magnetic tape by the magnetic heads is 5.5 mu m or less, the diameter of the rotating drum is 25 mm or less, and the track length per unit time is made to be a predetermined one by setting the rotating speed of the rotating drum at 150 rps or more. Thereby, long recording time is possible by a mechanism part of a small size and further, the error relative to the linearity of the track can be reduced.

摘要： A recording and reproducing device provided with at least a pair of rotary heads having different azimuths, running control means which controls the running of a magnetic tape, and recording timing control means which controls the recording by the rotary heads so that the recording can be performed in a first period when digital data having a first data rate are inputted, whereby the digital data can be recorded on the magnetic tape at the recording timing of the recording timing control means. In addition, the recording and reproducing device is also provided with a memory means which temporarily stores digital data supplied from the outside, reading means which reads out the digital data stored in the memory means, and signal processing means which performs a prescribed process of the digital data read out from the memory means. When digital data having a second data rate which is different from the first data rate are inputted, the recording timing control means and reading-out means perform processes at a speed based on the ratio between the two data rates and, at the same time, the running control means controls the running speed of the magnetic tape based on the data rate ratio.

摘要： A magnetic disk cartridge (20) having a plurality of generally rectangular-shaped strip liners (27a, 27b, 28a, 28b) placed in sliding contact with a magnetic recording sheet (26) to protect and clean the sheet (26). The strip liners (27a, 27b, 28a, 28b) are provided in pairs on each side of the magnetic recording sheet (26), each pair having first and second strip liners disposed on opposite sides of a central axis of the magnetic recording sheet. The strip liners for a 2.5 inch floppy magnetic disk cartridge have a length of approximately 4 to 5 cm and a width of approximately 1.6 to 2 cm. The strip liners (27a, 27b, 28a, 28b) are formed of a nonwoven fabric and are thermally welded to an inside surface of the upper and lower casings (21, 22) within a circumference of the magnetic recording material (26). The strip liners reduce manufacturing cost over conventional disk-shaped liners, and also provide a significant improvement in quality.

摘要： A topology map for a system is generated and displayed on a display device to indicate the various components which make up the system. The various components are indicated using icons each of which represent a respective one of the components. When a device is added to the system, a graphical image representing that device is automatically displayed in a graphical user interface. Similarly, when a device is removed from the serial bus, the graphical image representing that device is grayed out, leaving a shadow of the graphical image until the device is either re-coupled or the system is powered off. In a preferred embodiment, a user specifies a source device and a receive device by manipulating the corresponding icons so as to cause a data transfer between the source device and the receive device. In another embodiment, one or more task windows are included in the interface which help the user slect the task to be performed. Once selected, controls, commands and data related to the task are displayed within a control display window of the graphical user interface. Data transfer operations may include the transfer of video data, audio data, or both. In a further preferred embodiment, the digital network corresponds to the IEEE 1394 Serial Bus Standard.
