Appl. No.:

10/127743

Inventors:

Donald Henry Willis - Indianapolis IN
Shu Lin - Indianapolis IN

Assignee:

Thomson Licensing SA - Boulgone Cedex

International Classification:

H04N 701

US Classification:

348448, 348446, 348459

Abstract:

A method for format conversion includes providing a first interlaced video signal including non-progressive video of a first resolution, downconverting fields of the first resolution to fields of a second resolution, and combining and interlacing the fields at a third resolution. The video signal is transmitted at the third resolution. The video signal of the third resolution is deinterlaced to form a progressive format video. The progressive format video is converted to the first non-progressive resolution by alternately adjusting position of the progressive format of the third resolution up and down to make upper and lower fields, respectively, of the first resolution for display.

International Classification:

H04N 591

US Classification:

386 68, 386 82

Abstract:

Upon user selection of a particular trick mode, the number of pictures that are displayed can be accordingly adjusted to correspond with the selected trick mode speed based on a determined display time. Subsequently, the bandwidth usage can be can be determined to ensure that the channel capacity between a playback device ( ) and a remote decoder ( ) has not been exceeded. For forward trick modes, in a case where the bandwidth between the playback device ( ) and the remote decoder ( ) would be exceeded, B-pictures can be uniformly eliminated throughout the playback segment. Where B-pictures were present and they have been eliminated, they can be replaced by dummy B-pictures. Again, if there is still insufficient bandwidth available between the playback device ( ) and remote decoder ( ), then P-pictures can be eliminated from the playback segment and uniformly replaced by dummy P-pictures.

International Classification:

G11B 2700

US Classification:

369 83, 386 52

Abstract:

A method and device for editing to a picture a group of pictures (GOP) in a DVD media without decoding and encoding of an MPEG encoded signal. The method includes the steps of: marking a user selected end picture to identify a selected segment of the encoded signal to be edited; automatically identifying an actual end picture for the selected segment based on a position of the user selected end picture relative to at least one other picture within the encoded signal; and performing an edit function on an actual segment delimited by the actual end picture.

International Classification:

H04N 591

US Classification:

386 68, 386125, 386131

Abstract:

The invention includes a system and method for changing a playback speed of a selected video segment having repeat fields. To achieve fast motion play a selected video segment can be modified to delete repeat fields. Further pictures can be deleted as required to achieve a desired playback speed. To achieve slow motion play, a selected video segment can be modified by encoding repeat fields into conventional field pictures. Further pictures can be added as required to achieve a desired playback speed. Further, a repeat first field flag in the picture header of the picture containing the repeat field can be set to zero. Furthermore, a GOP structure of the modified video segment can be reencoded into a conventional or a desired GOP structure. Additionally, the modified video segment can be recorded exclusively on a desired portion of a storage medium.

International Classification:

US Classification:

386 52, 386 68, 386110

Abstract:

The invention includes a system and method for changing a playback speed of a selected video segment having a non-progressive frame structure which has been recorded onto a portion of a storage medium. A selected video segment can be modified for a changed playback speed and the modified video segment can be recorded exclusively on the portion of the storage medium. A plurality of non-video packs in the selected video segment can be deleted to reduce the amount of data contained in the modified video segment. The video segment can be modified by decoding the frames in the video segment, reencoding such frames into their associated field pictures and adding at least one field picture. Alternatively, the video segment can be modified by removing at least one frame or field picture contained in the video segment. In either arrangement, the video segment can be reencoded to produce a smoother trick mode and playback performance.

International Classification:

H04N 585

US Classification:

356125, 386124, 360 15

Abstract:

A method for copying a recorded series of bits from a first location to a second location on a rewritable disc media. The method includes the steps of selectively marking a beginning point and an end point of a segment of the recorded series of bits, and a location to which said segment is to be copied prior tp said reading step. Subsequently, video data comprising at least a portion of the segment of the recorded series of bits to be copied is read from the disk and stored in a track buffer of a DVD device. At least part of the video data from the track buffer is subsequently transferred directly from the track buffer to the record buffer by a control processor of the DVD device. Finally, the portion of the video data stored in the track buffer is written to the second location.

Abstract:

The invention concerns a method ( ) and system ( ) for searching for duplicate data. The method ( ) includes the steps of: generating ( ) at least one identifier from at least one portion of a first segment of data using a unique identifier function; generating ( ) at least one identifier from at least one portion of a second segment of data using the unique identifier function; and comparing ( ) at least one identifier associated with the first segment of data with at least one identifier associated with the second segment of data to determine whether the first segment of data is substantially identical to the second segment of data.

US Classification:

386 52, 386 95

Abstract:

Method and apparatus for editing a recorded series of bits on a rewritable disc media. The method includes the steps of selectively identifying a beginning point and an end point of a segment of the recorded series of bits to be deleted; and modifying a first jump command in a control data portion of the disc. The first jump command is modified for causing playback from the disc to continue at the end point when reading in a forward direction. The method can further include modifying a second jump command in a control date portion of the disc for causing playback from the disc to continue at the beginning point when reading data for playback in a reverse direction.
