Abstract: Examples relate to generating sync signals. An example apparatus includes an output, an input and a circuit. The output provides a data-valid signal to a video source operative to provide video data to a video-data-processing pipeline. The input receives a delayed data-valid signal from the video-data-processing pipeline. The circuit to generate a delayed horizontal-sync signal and a delayed vertical-sync signal at least partially responsive to the received delayed data-valid signal.

Abstract: A method may include obtaining samples associated with one or more symbols of a packet; determining at least one down-sampling point in a sequence of samples associated with a header portion of the packet; and utilizing samples associated with the determined down-sampling point to recover the one or more symbol and subsequent symbols.

Abstract: Examples disclosed herein include a video-data encoder. The video data encoder may encode a 4×4 data block into a bit stream according to a context adaptive variable length coding. The 4×4 data block may be representative of video data. The video-data encoder may, while encoding the 4×4 data block, ignore at least some coefficients of the 4×4 data block. In some examples, the video-data encoder may ignore the at least some coefficients of the 4×4 data block by setting the at least some coefficients of the 4×4 data block to zero prior to encoding the 4×4 data block. Related devices, systems and methods are also disclosed.
