  • Patent number: 8194988
    Abstract: Inverse transforms used in video and image compression/decompression, such as DCT/IDCT used in MPEG-2 and MPEG-4, or the integer transforms used in H.264, are usually calculated with fast algorithms, which only take advantage of the symmetry existing in the transform matrix but ignores the peculiarities in the input data. While these kind of fast algorithms can apply to both forward and inverse transforms, they tend to be inefficient in calculating inverse transforms. In inverse transforms, most of the coefficients become zero after quantization, this invention takes advantage of this fact to further simplify the general fast algorithm and speed up the calculation.

  • Publication number: 20090097596
    Abstract: Methods and systems are provided to reduce the effects of impulse noise in decoding a received OFDM signal by reducing the bit error number in burst error positions and by reducing the impulse noise contribution to channel estimation. In order to reduce the performance degradation due to impulse noise, it is important to find the position or the OFDM symbol where impulse noise occurs. The high noise variance gain can then be used for a Viterbi decoder to reduce the bit error number in burst error position, and also to reduce the contribution of the channel estimation by impulse noise in future channel estimations. Accordingly, the performance of the system can be greatly improved.

    Abstract: This invention describes methods for pre-computing neighboring locations for partitions in a video stream and for placing those pre-computed neighboring locations into a table for later retrieval and later use. The redundancy in the information of the pre-computed neighboring locations can be used to reduce the number entries in the table of neighboring locations, thus effectively reducing the amount of memory needed to store this table. Further, indexing schemes are used for non-MBAFF coded video streams and MBAFF coded video streams to further minimize memory usage.
