International Classification:

G06F015/173

US Classification:

709/226000, 709/225000

Abstract:

Methods and apparatus for automatically receiving and using a media access control address in router communications. If an ISP will authorize network communication only with a particular media access control address, a router can automatically use a non-native media access control, i.e. the media access control address registered with the ISP.

Sony Corporation - Tokyo

International Classification:

G06F 1110

US Classification:

371 401

Abstract:

A system and method for performing error correction on an SFAT format video signal which has been encoded using an error correction code ECC2, and generating a video signal reconstructed from the error-corrected input signal. The error code preferably is a cross interleave Reed-Solomon code. In a preferred embodiment, the system is capable of reconstructing the output video signal so that it has either SFA or SFAT format. Since an SFAT signal includes duobinary encoded data in its active video areas, and thus may be doubly error encoded using two error correction codes (ECC1 and ECC2), the invention is capable of generating from such a doubly encoded signal an ECC1 error-encoded video signal, in SFA (or SFAT) format, which has been error-corrected using error code ECC2. This capability is particularly advantageous where the invention is embodied in a video disk mastering system or method. In a preferred embodiment, the invention also determines the error rate of the input signal and generates a report signal indicative of the input signal's detected error rate.

Assignee:

Sony Corporation - Tokyo

International Classification:

H02P 516

US Classification:

318318

Abstract:

A motor control method and apparatus employing a speed control loop and a phase control loop, each of which receives a clock signal (F. sub. -- TACH) indicative of the motor's measured phase and rotational frequency, and a synchronizing clock signal (F. sub. -- SYNC) indicative of the desired motor operating speed control loop generates two analog voltage signals, V. sub. -- TACH and V. sub. -- SYNC, from frequency signals F. sub. -- TACH and F. sub. -- SYNC, and generates an error voltage signal proportional to the difference between these two voltage signals. Each frequency signal is first converted into a binary number signal proportional to the associated motor period (inverse frequency). Each such binary number signal is then converted to an analog voltage signal having magnitude proportional to the motor frequency. Each analog voltage signal is thus produced by a two-step process employing the successive reciprocal (division) elements.

International Classification:

G06F 1730

US Classification:

707 5

Abstract:

A software tool providing a single access mechanism for diverse and varied information spaces. The invention incorporates a plurality of navigator interfaces, including: a "How do I?" navigator, an Index navigator, a Tree navigator, and a Search Term navigator. Each navigator operates across the entire information space, allowing the user to find information in any available online source. The user can switch between the various navigators at will. The present invention presents search results to the user in a uniform manner through iconographic and textual descriptions of the information at the other end of the link. The user then selects the information to view. After the user has performed a search of the information space and viewed the description of the search results, the invention also allows the user to perform a "cross reference" operation, the results of which can be viewed using the same or different navigator. Certain embodiments echo the search results from a particular navigator in minimized display areas corresponding to the other navigators.

International Classification:

G06F 300

US Classification:

345347

Abstract:

Software implementing a display technique called "miniviews. " Miniviews provide a single viewing mechanism for information from a variety of sources and keep supplemental and related information within easy reach by a user without interrupting the flow of a main information concept. Miniviews are displayed when predetermined portions of the surrounding browser is expanded and can be displayed in any order as predetermined by the author, depending on the portions of the surrounding browser expanded by the user. Miniviews reference the original copy of the information displayed therein, such that if the information at the single location is changed, information displayed in the miniview is also changed. A miniview of information attempts to duplicate the appearance of the native browser for that information. At the same time, where a native browser allows the user to range freely through a certain type of information, miniviews only allow a predetermined amount of information from given source to be displayed.
