A system for encoding video data calculates a need parameter for an encoder and then adds a predetermined need bias value to the need parameter. The bias value is added without first determining video source complexity. The system then determines whether the input video comprises static video. Thereafter, the need parameter bias value is scaled in response to a determination that the input video includes the static video.

The present invention discloses a method and an apparatus for eliminating frequency-domain interference signals, and relates to communication technologies. The method includes: multiplying a frequency-domain channel estimation value by a frequency-domain interference signal to obtain a frequency-domain received interference signal; and subtracting the frequency-domain received interference signal from the frequency-domain received signal to obtain the frequency-domain received signal free of interference. The apparatus includes a multiplying module and a subtracting module. A frequency-domain equalizer includes an interference signal obtaining module and an interference signal eliminating module. The technical solution provided herein eliminates interference signals in the frequency domain, and saves the calculation load in contrast with elimination of time-domain interference signals.

A method, a video processing system, and an electronic device are disclosed. A video transcoder may decode a compressed video data frame creating a decoded video data frame. The video transcoder may embed a network presentation timestamp in the decoded video data frame. The video transcoder may re-encode the decoded video data frame creating a transcoded video data frame. A field programmable gate array may compare the network presentation timestamp with a transcoder presentation timestamp to determine a timestamp offset.

Coding may include receiving a source video bitstream including source frames and determining information from the source frames. The determined information may include timing information and grouping information and may be utilized in encoding synchronizing processed frames for a synchronized compressed video bitstream. Decoding may include receiving a synchronized compressed video bitstream including the encoding synchronizing processed frames. The decoding may include preparing video chunk files having boundaries defined by the encoding synchronizing processed frames and decoding the prepared video chunk files.

In one embodiment, a method for encoding content includes receiving source content and encoding the source content into a plurality of content streams. The encoding includes aligning the plurality of content streams at Group of Pictures (GOP) boundaries. The encoding further includes embedding, in each content stream, metadata identifying segmentation points within the content stream, where the segmentation points correspond to one or more of the GOP boundaries.

A method of programming a driving waveform for an electrophoretic display (EPD) is provided, wherein the driving waveform includes several single pulses selected from K candidate pulse widths W1˜WK. First, K different constant pulse sequences corresponding to W1˜WK may be applied to the EPD, to obtain K sets of discrete electro-optical response data. A polynomial curve fitting algorithm is applied to obtain K relation curves C1˜CK between contrast ratios of the EPD to time, corresponding to the K sets of discrete electro-optical response data. After calculating the slope values S1˜SK of the curves C1˜CK at a current contrast ratio of the EPD, a maximum slope Smax among S1˜SK and a specific pulse width Ws corresponding thereto are determined. A next contrast ratio of the EPD is calculated according to Ws and Smax. The design process is repeated until the next contrast ratio of the EPD exceeds a target value.
