  • Patent number: 8482670
    Abstract: Gradient analysis may be utilized to determine frame and field repeat patterns in input video data. Those frame and field repeat patterns may then be analyzed to match them with characteristic patterns associated with telecine 3:2 and 2:2 pulldown video data, for example. In addition, a progressive detector may use combing analysis to determine whether or not a particular field is progressive or interlaced data. Then, this information, together with a field flag which indicates whether field or frame analysis is appropriate, may be utilized to distinguish telecine 2:2 or 3:2 pulldowns and interlaced and progressive data in some embodiments.

  • Patent number: 8421923
    Abstract: As information to be processed at an object-based video or audio-visual (AV) terminal, an object-oriented bitstream includes objects, composition information, and scene demarcation information. Such bitstream structure allows on-line editing, e.g. cut and paste, insertion/deletion, grouping, and special effects. In the interest of ease of editing, AV objects and their composition information are transmitted or accessed on separate logical channels (LCs). Objects which have a lifetime in the decoder beyond their initial presentation time are cached for reuse until a selected expiration time. The system includes a de-multiplexer, a controller which controls the operation of the AV terminal, input buffers, AV objects decoders, buffers for decoded data, a composer, a display, and an object cache.

  • Patent number: 8405774
    Abstract: A synchronization signal control circuit according to embodiments includes a phase difference detecting section and a vertical synchronization correction control section. When a vertical synchronization period of an input video signal is within a compensation period range between a minimum vertical synchronization period and a maximum vertical synchronization period, the synchronization signal control circuit outputs a display vertical synchronization signal used for displaying the input video signal to a display section capable of providing a display based on the input video signal. The phase difference detecting section detects a phase difference between an input vertical synchronization signal based on the input video signal and the display vertical synchronization signal. The vertical synchronization correction control section corrects the cycle period of the display vertical synchronization signal within the compensation period range so as to reduce the phase difference.

  • Patent number: 8363166
    Abstract: A Gaussian filter 2 having a first cutoff frequency extracts a low frequency component signal of a video signal. A subtracter 3 extracts a high frequency component signal by subtracting the low frequency component signal from the video signal. A low pass filter 5 having a second cutoff frequency higher than the first cutoff frequency extracts a lower high frequency component signal, which is a low-frequency-side signal of the high frequency component signal. A multiplier 6 generates a corrected component signal by multiplying the lower high frequency component signal by a predetermined gain G1. An adder 7 adds the corrected component signal to the video signal.
