  • Publication number: 20230388020
    Abstract: A method for optical transceiver misconnection identification that allows a simple low-level process to monitor and communicate optical transceiver characteristics information between two optical transceiver modules regardless of their transceiver type to determine if they are correctly connected or mismatched. If a mismatch is determined, the knowledge gained about the transceiver type of a far end module may be obtained (and presented to an installer) and used by an installer to select and install a module that is operationally compatible with the far end optical module.

  • Publication number: 20230353789
    Abstract: A de-blocking filter includes a reconstructed memory that is configured to store reconstructed pixels corresponding to a current macroblock of a video image to be filtered. The current macroblock includes a set of sub-blocks, each sub-block having horizontal edges and vertical edges. An internal pixel buffer in the de-blocking filter is configured to store pixels corresponding to the set of sub-blocks from the reconstructed memory, and to store partially filtered pixels corresponding to a set of partially filtered macroblocks. An edge order controller in the de-blocking filter is configured to load the pixels corresponding to the set of sub-blocks into a filter engine from the internal pixel buffer, to filter the set of sub-blocks, such that, at least one horizontal edge is filtered before filtering all vertical edges of the set of sub-blocks.

  • Patent number: 9612962
    Abstract: In certain embodiments, methods and systems for multimedia data processing are provided. In an embodiment, a method for processing multimedia data includes defining one or more pixel block regions in a first cache so as to cache a plurality of reference pixel blocks corresponding to reference data. A reference pixel block from among the plurality of reference pixel blocks is assigned to a pixel block region from among the one or more pixel block regions based on a predetermined criterion. The reference pixel block is associated with a tag based on the pixel block region so as to facilitate a search of the reference data in order to process a plurality of pixel blocks associated with a multimedia frame of the multimedia data.

  • Patent number: 9602841
    Abstract: A system and method for decoding video encoded using scalable video coding. In one embodiment, a decoder for scalable video coding (SVC) includes an SVC access unit analyzer and decoding logic. The SVC access unit analyzer is configured to examine an SVC access unit prior to layered decoding of the access unit, to determine, based on the examination, what operations the access unit specifies for each layer of the decoding, and to determine, based on the determined operations to be performed for each layer of the decoding, what data to store for use by a subsequent layer of the decoding. The decoding logic is configured to decode the access unit via a plurality of decoding layers; and to store at each decoding layer, for use by a subsequent decoding layer, the data determined by the SVC access unit analyzer to be used by the subsequent decoding layer.
