Patent number: 7274409Abstract: A tuner is controlled to manage noise and distortion levels in a video signal. The tuner recovers an RF modulated video signal. A video demodulator provides a baseband video signal from the recovered RF modulated video signal. At least one of signal-to-noise ratio (SNR) and intermodulation distortion (IMD) is determined for the baseband video signal. An AGC attack point of the tuner is dynamically controlled in response to the SNR and/or IMD in order to improve the video quality.Type: GrantFiled: August 2, 2004Date of Patent: September 25, 2007Assignee: General Instrument CorporationInventor: David E.

Patent number: 6901603Abstract: Advanced recording options are provided on a personal versatile recorder (PVR) or similar recording device. Television signals and associated electronic programming guide (EPG) data are received at a receiver (30). Recorded program material is stored in a storage device (60). A processor (75) provides for automatic suspending of recording, based on predetermined criteria, for at least a portion of time during which the one or more television programs would otherwise be recorded. Recording may be suspended when non-programming specific content (e.g., a commercial or emergency broadcast) is received at the PVR (20). Non-program specific content can be identified through the use of EPG data or Advanced Television Enhancement Forum (ATVEF) triggers. End of program notifiers may be provided which enable the PVR (20) to record the entire program, regardless of whether the program runs beyond its scheduled time. Recording may be optionally suspended where the program is a rerun.Type: GrantFiled: July 10, 2001Date of Patent: May 31, 2005Assignee: General Instrument CorportionInventors: David E. Zeidler, Wayne D. Woodruff, Robert M. Simons

Patent number: 6829014Abstract: A frequency range bounder for limiting the frequency of a voltage controlled oscillator uses a multiplexer that responds to comparator inputs indicating whether an input control signal will allow the oscillator frequency to go beyond a predetermined range. If the control signal keeps the frequency within the range, the control signal is sent directly to an oscillator driver. If the control signal is above or below the range, the multiplexer outputs an alternative value as the control signal. As a result, the oscillator frequency is prevented from extending beyond an allowable tolerance range.Type: GrantFiled: May 4, 2001Date of Patent: December 7, 2004Assignee: General Instrument CorporationInventors: David E. Zeidler, Brian Carroll

Patent number: 6791622Abstract: Methods and apparatus for reducing the artifacts associated with still frame display and video capture of interlaced video are provided. Tuner 100 receives an interlaced video signal having an image frame with first and second fields. Motion detector 55 detects whether motion is present between the first and second fields. Memory 40 stores one or both of the fields for processing when motion is detected. Processor 30 processes the stored field(s) to provide an image frame with reduced artifacts. Various processing techniques are provided to generate the image frame from the stored field(s), without duplicating the stored field for use as the other field. Memory 40 stores the image frame. If motion is not detected, the first and second fields are both stored to provide the image frame. The stored image frame can then be continuously displayed to provide still frame display, or can be captured for subsequent use.Type: GrantFiled: August 31, 2001Date of Patent: September 14, 2004Assignee: General Instrument CorporationInventors: David E.

Publication number: 20040090556Abstract: A technique is used for determining a video format for a video output signal generated by a television receiver. The technique includes acquiring a preferred output format that is one of a plurality of video formats and determining an aspect ratio of a selected television signal having one of a plurality of television signal formats. The video output signal is generated using one of the plurality of video formats having a 4:3 aspect ratio when the selected television signal has a television signal format having a 4:3 aspect ratio and the preferred output format is other than one that has only a 4:3 aspect ratio. A related technique additionally acquires an optional override output format for television signals having an aspect ratio of 4:3 that is used to determine when to use the stated the stated video format to generate the video output signal.Type: ApplicationFiled: November 12, 2002Publication date: May 13, 2004Inventors: John Kamieniecki, Joseph F.

Patent number: 6734898Abstract: The present invention relates to methods and apparatus for measuring the quality of video (e.g., television) signals. In particular, the methods and apparatus of the present invention allow for the measurement of various quality parameters of analog or digital video signals at a set-top terminal 10 or similar device, without the need for external test equipment. A video signal 14, which contains a test signal, is received at a decoder 20. The video signal 14 is decoded and temporarily stored in memory 40. A processor 30 associated with the decoder 20 and the memory 40 analyzes the test signal and calculates a quality parameter for the received video signal 14 based on the test signal. The quality measurements can also be accessed remotely and downloaded, for example, by a cable television provider at a cable television headend. The video quality measurement may include various indicators of end-to-end system performance, including the performance of the set-top terminal 10 or similar device.Type: GrantFiled: April 17, 2001Date of Patent: May 11, 2004Assignee: General Instrument CorporationInventor: David E.

Publication number: 20040049785Abstract: An Alert/Warning Interface resides in a set top box, which is coupled to a user's television, and an Information Server located in the cable plant origination center or head-end. The end user of the set top box is able to configure a profile that includes weather areas to be monitored, roads traveled, and schools their children attend. This profile is stored on the Information Server, along with the profiles of all other users. The Information Server monitors for alert conditions, such as bad weather, traffic jams, and school closings. If any of these events occurs, a message is sent to the set top box associated with a profile indicating the current error condition. Upon receipt of an Alert message, the set top box places an icon (or other graphic) in a predetermined portion of the screen (e.g., a top/bottom corner) indicating an alert has occurred. The user can then switch to the Alert screen view, at which time the Alert icon turns off.Type: ApplicationFiled: September 6, 2002Publication date: March 11, 2004Applicant: General Instrument CorporationInventors: Richard Stephen Grzeczkowski, David E.

Patent number: 6556250Abstract: A circuit for providing a sufficiently accurate clock signal for reconstruction of an image from a video signal can function with or without receiving an incoming video signal containing clock data. In this way, a clock signal for supporting an on-screen display can be created in the absence of an incoming video signal. Control data used to control a voltage controlled oscillator generating a clock signal is recorded when the control logic of the oscillator is locked to the timing data in an incoming video signal. In the absence of an incoming video signal, the recorded control data is retrieved and resubmitted to the control logic so that the oscillator can be made to output an appropriate clock signal even in the absence of an input video signal.Type: GrantFiled: August 10, 1999Date of Patent: April 29, 2003Assignee: General Instrument CorporationInventors: David E.
