Patent number: 7664369Abstract: In the known color stripe process for preventing recording of video signals, the color burst present on each line of active video is modified so that any subsequent video tape recording of the video signal shows variations in the color fidelity that appear as undesirable bands or stripes of color error. This color stripe process is improved by a combination of modifying the phase of the color burst on only part of the color burst. Additional improvements were obtained by incorporating techniques of widening the normal color burst envelope towards the trailing edge of horizontal sync and towards the beginning of active video. These techniques are useful in improving the performance of the color stripe process in both the NTSC and PAL color systems. However, additional improvements are described in the PAL system whereby the phase modifications are controlled so as to avoid disturbing the so-called PAL ID pulse.Type: GrantFiled: June 19, 2002Date of Patent: February 16, 2010Assignee: Macrovision CorporationInventors: William J. Wrobleski, Ronald Quan

Patent number: 7587131Abstract: A method of operating an electronic video device such as a DVD player, wherein video clock signals and audio clock signals are derived from a system clock signal using two phase-lock loops, and these video and audio clock signals are used to process encoded video data and encoded audio data, but digital-to-analog conversion of the audio data stream is controlled by the system clock signal rather than the audio clock signals. By using the system clock signal to control the audio digital-to-analog converter (DAC), the DAC avoids the poor performance issues that can arise from the jitter introduced into the audio clock signals by the PLL. The system clock signal may be divided by an integer to generate the sampling clock for the audio DAC. In the illustrative embodiment, the system clock signal has a rate which is not an integer multiple of the sample rate of the audio data stream. For example, the system clock rate might be 27 MHz while the sample rate of the audio data stream is 44.1 kHz.Type: GrantFiled: May 28, 2004Date of Patent: September 8, 2009Assignee: Magnum Semiconductor, Inc.Inventors: John L.

Patent number: 7532805Abstract: An AV data recording/reproducing device is connected to a digital broadcasting tuner and the like via an IEEE1394 bus, in order to realize high-speed transfer when duplicating or transporting AV data between devices such as audio-visual data recording/reproducing devices. A synchronous transfer input/output portion inputs and outputs stream data that are AV data by isochronous transfer with an MPEG-2 transport stream. A recording control portion and a reproduction control portion generate timestamped data and reproduce the stream data, and an HDD stores the timestamped data. An asynchronous transfer input/output portion asynchronously inputs and outputs the timestamped data by SBP-2 transfer. Consequently, the timestamped data that can reproduce the stream data are transferred at high speeds, regardless of an actual time required for performing the display or the like of the stream data.Type: GrantFiled: July 10, 2003Date of Patent: May 12, 2009Assignee: Panasonic CorporationInventors: Masahiro Okada, Yuji Tanikawa, Kazuhiro Mihara

Patent number: 7298965Abstract: Often, during an event, such as a movie, play, concert, opera, etc., viewers of the event attempt to illicitly record the event. Such illicit recording attempts may be interfered with by using emitters that emit radiation that interferes with recording and/or operation of the recording devices. For example, infrared emitters may be used to saturate an event viewing area. The infrared, while non-visible to human viewers, is received and recorded by recorders using charge-coupled devices (CCDs), such as conventional digital cameras, movie cameras, television cameras, telescopes, etc. Other radiation can be emitted based on the type of recorder with which one desires to interfere. Alternatively, or in addition thereto, emitters may also be used to send commands to recorders, such as stop, rewind, eject, etc., to interfere with operation of the recorders.Type: GrantFiled: December 14, 2004Date of Patent: November 20, 2007Assignee: Intel CorporationInventor: Stephen P.
