摘要:
In accordance with the principles of the present invention, advantage is taken by the inventors of the fact that the speed of operation of the digital hardware in a digital beamformer having a plurality of parallel receiving channels can be reduced by providing multiple phases for the data signals supplied by each receiving channel and then processing the multi-phase data in N parallel summing paths. An interpolation-decimation filter receives the multi-phase data from the N parallel summing paths and provides at its output a signal having a reduced data rate (1/N). In accordance with this technique, the speed of operation of the individual digital circuits for forming the required beamforming delays are not increased as compared to conventional post-beamforming interpolation schemes, so that hereby the effective data rate is increased by a factor N and the delay quantization error is reduced by a factor N.

摘要:
During encoding, blank frames may be substituted for text images in video content, encoding the blank frames instead of the text images. The text images may be any kind of text images such as opening credits, ending credits, and so on. The selection of text images to substitute may be performed by optical character recognition, user selection and so on. The text associated with the text images may be embedded in the encoded video. If the text is already embedded, an indicator of the location may be added. If not, the text may be derived from the text image using optical character recognition and then embedded. When decoded, the encoded video may be analyzed to determine whether blank frames were substituted for text images. Embedded text associated with the text images may then be located, obtained, and added to the decoded video. Thus, the original text images are essentially reconstructed.
