摘要： A computer readable memory to direct a computer to improve the perceived audio quality of a speaker included in that computer. The computer readable memory stores a first, second and third set of instructions. The first set of instructions causes the computer to determine the speaker type. The second set of instructions causes the computer to select a set of default filter coefficients for a digital filter based upon the speaker type. Finally, the third set of instructions causes the computer to realize a digital parametric equalizer using a digital filter and the set of default filter coefficients. Thus, the digital filter alters the audio signal that is input to the speaker, thereby improving the perceived quality of the speaker.

摘要： Techniques for video data delivery are provided. A first data stream is received that includes a plurality of video data frames. At least one corrupted video data frame is detected in the first data stream. At least one replacement video data frame is generated for the corrupted video data frame(s) based at least on a non-corrupted video data frame received in the first data stream prior to the corrupted video data frame(s). The replacement video data frame(s) include a modified form of the non-corrupted video data frame, and are configured to provide a smooth scene transition from the non-corrupted video data frame. The corrupted video data frame(s) are replaced in the first data stream with the generated replacement video data frame(s) to generate a second data stream.
