    摘要： A method for operating a receiver is disclosed. The receiver may receive, over a channel from a transmitter, a first data bit at a first period of time. The receiver may receive, over the channel, a second data bit at a second period of time subsequent to the first period of time. The first and second data bits each have either a first logical value corresponding to a voltage greater than zero volts or a second logical value corresponding to a voltage less than or equal to zero volts. The receiver performs a coefficient adaptation operation, using the first data bit, to adjust one or more coefficients of a decision feedback equalizer of the receiver only when the logical value of the first data bit is equal to the logical value of the second data bit.

    摘要： A method and apparatus are disclosed for predicting subjective quality of a video contained in a bit stream on a packet layer. Header information of the bit-stream is parsed and frame layer information, such as frame type, is estimated. Visible artifact levels are then estimated based on frame layer information. An overall artifact level and quality metric are estimated based on artifact levels for individual frames with other parameters. Specifically, different weighting factors are used for different frame types when estimating the levels of initial visible artifacts and propagated visible artifacts. The number of slices per frame is used as a parameter when estimating the overall artifact level for the video. Moreover, the quality assessment model considers quality loss caused by both coding and channel artifacts.
