In accordance with the present invention, there is provided a system and method for dark noise reduction in pulse width modulated (PWM) displays. The system includes means for determining bright corrected pixel values for dark portions of an image corresponding to a first subframe and means for determining dark corrected pixel values for dark image portions of an image corresponding to a second sub frame of the image frame.

System and method for dark noise reduction in pulse width modulated (PWM) displays

A video processing system adaptively generates and processes volume/file structure and navigation data of different data format and converts data between different formats for decoding, recording and other applications. The system processes the volume/file structure and navigation data in distinct modes including (a) pre-processing, (b) contemporaneous and (c) post-processing modes. In addition, the system provides navigation information supporting navigation through different images of one or more video programs by parsing encoded packetized data representative of a sequence of individual images to determine parameters to support navigation through the sequence of individual images. The determined parameters are formatted into a predetermined data structure and incorporated into a pre-formed navigation data field.

A method () and system () for performing a trick mode on a video signal. The method includes the steps of receiving () a trick mode command, in response to the trick mode command, repeating () a picture in the video signal to form a trick mode video signal in which the picture contains a display indicator; setting () the display indicator of the picture being repeated to a predetermined value; and setting () the display indicators of subsequent repeated pictures of the picture being repeated to the predetermined value. In one arrangement, the trick mode can be a freeze trick mode, and the picture to be repeated can be a bidirectional predictive picture. In addition, the display indicator can be a temporal reference field having an integer value.

The invention concerns a method () and system () performing a trick mode on a video signal containing a plurality of original pictures. The method includes the steps of selectively skipping () at least one of the original pictures to convert the video signal to a trick mode video signal in response to a trick mode command and selectively inserting () at least one dummy bidirectional predictive picture in the trick mode video signal using field-based prediction. The method can also include the steps of monitoring () the trick mode video signal in which the step of selectively inserting at least one dummy bidirectional predictive picture in the trick mode video signal can be done if the bit rate of the trick mode video signal exceeds a predetermined threshold.

A method for providing improved trick mode performance in a DVD having a plurality of video object units where each of the VOBUs contains a navigation pack. The method involves storing on the DVD within each navigation pack certain supplemental disc search information. The SDSI can include one or more of the following: a picture structure of the VOBU; a number of fields to be displayed from each picture in a normal play mode; and a number of groups of pictures contained in said VOBU.

A method of performing a trick mode on a video signal includes the steps of receiving a trick mode command and repeating a picture in the video signal to form a trick mode video signal in response to the trick mode command. If the picture being repeated is a bi-directional predictive picture, then the method can limit the repeating step to a predetermined number of times.

Frame advance and slide show trick modes

A method for presenting video content including displaying the video content at an enhanced frame rate selectively modified to interfere with a recording of the video content by a camcorder. For example, the video content can be displayed at a frame rate of 54 pictures per second or a frame rate of 66 pictures per second. For implementation of the enhanced frame rate, a first picture can be displayed within the video content a first number of times and at least a second picture can be displayed a different number of times.

A method () of converting interlaced Moving Picture Experts Group (MPEG) video signals to progressive video signals can include receiving an interlaced video signal representing a luma component specifying luma lines and a chroma component specifying chroma lines () wherein the chroma component can specify approximately one-half the number of lines of the luma component. The interlaced video signal can be decoded and the number of the chroma lines can be increased to approximately the same as the number of the luma lines (). The number of chroma lines of the interlaced video signal then can be decreased (), to substantially reverse the previous increase. The interlaced video signal then can be deinterlaced to produce a progressive video signal (), which can be processed further () as needed.

The invention concerns a method and system for performing a trick mode on a video signal containing a plurality of original pictures. The method includes the steps of selectively skipping at least one of the original pictures to convert the video signal to a trick mode video signal in response to a trick mode command and selectively inserting at least one dummy predictive picture in the trick mode video signal using field-based prediction. The method can also include the steps of monitoring the trick mode video signal in which the step of selectively inserting at least one dummy predictive picture in the trick mode video signal can be done if the bit rate of the trick mode video signal exceeds a predetermined threshold.

A method and apparatus for eliminating picture artifacts in a video media system is provided wherein a video recorder, responsive to a trick mode command, iteratively transmits one or more frames in a video signal recorded under an interlaced scanning format for display on a display device. The video signal can include a predetermined number of replicate frames associated with the frames. Moreover, structure can be provided for selectively altering the video signal to indicate the video signal was recorded under a progressive scanning format thereby causing one or more pairs of the interlaced fields associated with the frames in the recorded video signal to be simultaneously displayed on the display device. Displaying interlaced fields simultaneously during trick mode playback eliminates an artifact known as the vibration effect. In one embodiment, the structure can alter the video signal by setting the value of one or more flags in the video signal. In addition, a decoder for decoding the video signal can be remotely located, for example, in the display device, or can be mounted in the video recorder.

The invention concerns a method and system for generating a dummy bidirectional predictive (dummy B) field picture. The method includes the steps of setting at least a portion of a first indicator of the dummy B field picture to indicate that no encoding of a residual signal will occur and setting at least a portion of a second indicator of the dummy B field picture to indicate that the dummy B field picture will be predicted from at least one field among a first field and a last field of a reference picture to control a vibration artifact. The dummy B field picture can be a forward or a backward predicted field picture, and the at least one field from which the dummy B field picture is predicted can be a first or last field of the reference picture.
