摘要： A system for deinterlacing encoded video data includes a demultiplexer for receiving the encoded video data and producing motion information and compressed video data corresponding to the encoded video data. A motion compensated predictor generates predicted image data based on the motion information corresponding to the encoded video data. A variable length decoder decodes the compressed video data corresponding to the encoded video data to produce residual data. An adder combines the residual data and the predicted image data to generate an interlace field and a memory stores picture data corresponding to the interlace field. A controller processes the motion information and generates motion vectors and a control signal corresponding to the motion information. A motion compensated deinterlacer manipulates the picture data corresponding to the interlace fields from the memory according to the motion vectors and the control signal to generate a corresponding deinterlace picture.

摘要： A method and system in which a user manually changes the quality of specific time periods of encoded video. After the automatic encoding of video into a compressed digital format, a person editing the encoded video reviews the quality of the video and manually indicates that the quality of specific time periods of the video is to be altered. As the digital storage medium such as an optical disc which stores the encoded video has a finite storage capacity, the total number of bits for the encoded video and the quality of the video is limited. Consequently, in order to increase the quality for one time period, bits must be taken from other time periods. After the editor assigns the qualities to different time periods, a percentage of bits is removed from the time sequences and placed into a bit pool. The new number of bits for the various time periods are calculated using an exponential function and the bits in the bit pool are proportionally distributed to the video frames. The frames must then be checked and possibly adjusted to assure that underflow of the video buffer will not occur. After the underflow checking procedure, the video is re-encoded with an adjusted quantization in accordance with a quantizer model which will result in a picture having the calculated number of bits and a quality in accordance with the user's selection.

摘要： A television deghosting system includes an IIR filter having programmable filter coefficients which processes the input signals to remove ghost signal components. The IIR filter may be reconfigured as an FIR filter, having its coefficient and delay values changed to operate as a matched correlation filter. In this mode the filter is used to correlate a training signal to determine the relative delays of ghost signals with respect to the direct signal. The training signal used is the sum of the squared differentials of the in-phase and quadrature-phase components of the video IF signal during an interval defined by the leading edge of the vertical sync pulse and the first equalization pulse.

摘要： A system for coordinated playback of time-shifted content with time-adapted complimentary content is provided. The time-shifted content may be played back from storage media, both local and remote. Time-shifting may occur by independent playback such as from optical discs and other memory devices, as well as from user manipulation of features in a playback system based upon real-time or near real-time content distribution. The content is identified, along with timing information identifying where in the content the playback is occurring. Time-adapted complimentary content may then be selected and transmitted to the playback system. Such time-adapted content may include advertisement, product and service offerings, complimentary information, audio and/or video content, and so forth.

摘要： Digital content, such as video, audio, multimedia, and similar files may be associated with metadata that is in some manner descriptive of the content by means of a unique identifier generated based on the content or a portion of the content. The two may be packaged in a wrapper. If the content is separated from the metadata, such as by circulation in a non-compliant environment, the content may be recognized by a regeneration of the identifier. Based upon the re-created identifier, the metadata may be re-associated with the content. Other scenarios may include generation of compilations for files that are not included in a wrapper with content and metadata, content that becomes dissociated with metadata by transcoding, and so forth.

摘要： A method and system in which a section of a previously encoded digital bit stream is replaced with another section of encoded video. In order to remove a section of encoded video, it is necessary to determine the beginning and ending points of the encoded video in the digitally encoded bit stream. The addresses of the beginning and ending points of the encoded data cannot be simply looked up but are calculated by summing the bits consumed by each picture, the number of bits of the sequence header of each picture, the number of bits of each Group of Pictures (GOP) header, and all stuff bits. In order to encode the video which is to be inserted in place of the removed video, a process is performed which prevents decoding artifacts from appearing. This is accomplished by determining the last P-picture before the edit point and using it as a reference frame for frames after the edit point. Additionally, a short period of the original video encoded using its original quantizer values is included at the end of the video to be substituted. Alternatively, the encoder may be run so that an earlier encoded reference picture is not used. However, this requires extra bits to maintain picture quality because initial bidirectional frames of the substitute video will use only one reference frame instead of two.

摘要： Systems and methods are provided for allowing responses to offers displayed with digital content. The responses may be provided on a receiver system via a conventional feedback through the same distribution channel through which the content and offer were provided, or through an alternative channel, with data being transmitted from an alternative channel device to a transacting entity. For time-shifted playback, content is identified and time-adapted offers may be provided, taking into account factors such as the content, the time of play back, the date of play back, and so forth. The alternate response channel may be more suitable for time-adapted offer responses then for contemporaneously transmitted offers.
