摘要： A method and network element include receiving, at a receiver node, at least one of sender timestamps and sequence numbers in continuity check (CC) frames sent by a sender node; determining receiver timestamps at the receiver node; detecting instability based on one or more of the at least one of sender timestamps and sequence numbers and the receiver timestamps; and performing a remedial action based on the detecting instability. The CC frames can include Bidirectional Forwarding Detection (BFD) or Continuity Check Message (CCM) frames which are regularly transmitted in a session, but do not currently include timestamps or sequence numbers.

摘要： An apparatus and method for video fingerprinting are provided. The method includes, for each frame of a video sequence including a plurality of frames, removing a portion of the frame, dividing a remaining portion of the frame into blocks, dividing each block into sub-blocks, computing a block level feature as a mean of pixels in each sub-block within the block, concatenating all block level features in the frame, and concatenating features of all frames in the video sequence.

摘要： An apparatus and method for processing video data are provided. The method includes determining a primary transform CN for application to residual data at the encoder, determining a secondary transform TrK for application to the residual data, applying the primary transform CN to the residual data, and selectively applying the secondary transform TrK to the residual data, wherein N denotes the length size of the input vector on which the primary transform CN is applied, and K denotes the length of the first few coefficients of the primary transform output on which the secondary transform TrK is applied. Similar inverse operations are performed at the decoder, viz., selectively applying an inverse secondary transform inv(TrK) at the decoder for the input residual data, followed by application of the inverse primary transform inv(CN).
