Title: The copy protection of digital audio compact discs
Inventor: EDWARDS ROGER
IPC: G11B11/00
Filed: 2001-02-14
Abstract: The ability of a data reader to access, extract, or otherwise read the data on a CD-DA provides a problem for the music industry. A user can use his CD-ROM  drive to read the data from an audio disc into a computer file, and then tha t data can be copied. Therefore, errors are deliberately introduced into the encoded data, these errors being of a type which are generally transparent t o an audio player but which will interfere with the extraction or reading of t he audio data by a data reader. The data on a CD is encoded into frames by EFM (eight to fourteen modulation), and each frame includes 24 bytes of audio data. There are 8 sub-code bits contained in every frame which enable 8 different subchannels, P to W, to be formed. The P- and Q- subchannels incorporate timing and navigation data for the tracks on the disc, and generally are the only subchannels utilised on an audio disc. It is the timi ng and/or navigation data in the P- and Q- subchannels which is rendered incorrect or inaccurate to provide the copy protection.

Inventor: BLOW ANTHONY T
IPC: H04W4/24
Filed: 2000-04-12
Abstract: A system and method for inserting and distributing commercial advertising to wireless phone subscribers. The system and method also allows for information gathering from participating subscribers. A subscriber enters a user profile either when initially signing up for service or through an interactive menu on the phone handset (330). Through phone registration messages transmitted as overhead messages within the wireless network (320) the network (320) is roughly able to determine the location of the phone (330). The system transmits advertising messages to the user at call origination based upon the user profile and cell location. The system may use the subscriber location to decide to transmit messages to the user phone that will launch a browser (336) like application within the phone (330). The browser (336) would then display textual or graphical advertisements on the handset display. Additionally, the system could initiate browser pop-up polling queries in which the user could offer responses. The phone (330) would use packetized data transmission to transmit the responses back to the base station (320). The system would then accumulate and process the various user responses. The system could also use location information to selectively transmit electronic coupon offers to local subscribers.

Title: System and method for virtual television program rating
Inventor: KOHEN OFFER
IPC: G06Q30/02
Filed: 2000-06-26
Abstract: A method and a system for combining at least two sources of television program rating information, including at least one source obtained through user input into an electronic interface, to provide a more accurate and focused rating for a particular television program. The source of rating information which is obtained through an electronic interface is preferably obtained through the active interaction of the user with a Web browser, for example through an applet or a Web page, or a combination thereof. The advantage of such active interaction is that the user <i>wants</i> to provide the rating information, thereby requiring more involvement by the user than merely passively viewing a television program. Such a system and method is also useful for rating advertisements, for which passive rating methods may not be as effective.  Furthermore, more precise demographic information can be obtained through such an interaction with the Web browser, since the user can be requested to enter such precise information. Advertisers are interested in such demographic information, such that the system and method of the present invention may provide useful indicators of the interest of various groups of users in specific television programs. Television networks which schedule television programs are also interested in demographic information in order to be able to select television programs and to promote these television programs more effectively. Thus, the system and method of the present invention is useful for providing more accurate an specific rating information for television programs and advertisements, as well as for promoting these television programs and advertisements.

Abstract: The invention relates to a method and an apparatus for determining quality properties of fish on the basis of light reflection. A fish and a reflection  measurement device (5) with a light emitter and a light receiver (6) are positioned in relation to each other, with the light emitter and light receiver of the device directed towards the fish's inner abdominal wall with  peritoneum, so that the light emitter illuminates an area of the fish throug h the peritoneum and the light receiver captures the light reflected from the fish. The intensity of reflected light is registered in three or more different wavelength bands in the visible and near-infrared range. The measurement results registered are, after any processing, entered into an algorithm in a calculation unit, which algorithm expresses a quality propert y of fish on the basic of the reflection of its inner abdominal wall with peritoneum in three or more different wavelength bands in the visible and ne ar- infrared range. The calculation unit automatically calculates the quality property by means of the algorithm and the measurement results. The intensities of reflected light are registered in both the visible range, especially between 400 and 600 nm, and in the near-infrared range, especiall y between 850 an 1050 nm. By means of the methodit is possible to measure quality properties of individual fish in a short time in non-destructive manner, especially the colour, astaxanthin content and/or fat content of salmon.
