Publication number: 20230388020Abstract: 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.Type: ApplicationFiled: August 10, 2023Publication date: November 30, 2023Inventors: Gudipaty Vasanta Rao, Anjali Mysore Vijayakumar, Ratna Reddy Chada, Joanne Tse, Darja Padilla, Mark Charles Nowell

Publication number: 20230353789Abstract: 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.Type: ApplicationFiled: July 10, 2023Publication date: November 2, 2023Inventors: Niraj Nandan, Mullangi Venkata Ratna Reddy

Patent number: 9602841Abstract: 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.Type: GrantFiled: October 30, 2012Date of Patent: March 21, 2017Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Manu Mathew, Mullangi Venkata Ratna Reddy
