Long-term reference picture signaling in video coding
A video encoder signals, in a slice header for a current slice of a current picture, a first long-term reference picture (ltrp) entry, the first ltrp entry indicating that a particular reference picture is in a long-term reference picture set of the current picture. Furthermore, the video encoder signals, in the slice header, a second ltrp entry only if second ltrp entry does not indicate that the particular reference picture is in the long-term reference picture set of the current picture..

Indication and activation of parameter sets for video coding
In some examples, a video encoder includes multiple sequence parameter set (sps) ids in an sei message, such that multiple active spss can be indicated to a video decoder. In some examples, a video decoder activates a video parameter set (vps) and/or one or more spss through referencing an sei message, e.g., based on the inclusion of the vps id and one or more sps ids in the sei message.

Error resilient management of picture order count in predictive coding systems
Coding techniques for input video may include assigning picture identifiers to input frames in either long-form or short-form formats. If a network error has occurred that results in loss of previously-coded video data, a new input frame may be assigned a picture identifier that is coded in a long-form coding format.

Histogram segmentation based local adaptive filter for video encoding and decoding
Reconstructed picture quality for a video codec system may be improved by categorizing reconstructed pixels into different histogram bins with histogram segmentation and then applying different filters on different bins. Histogram segmentation may be performed by averagely dividing the histogram into m bins or adaptively dividing the histogram into n bins based on the histogram characteristics.

Method for ip longest prefix match using prefix length sorting
Prefix length memory tables are used to enable fast ipv4 lpm lookups using a single memory access for a first range of ip prefixes, and using two memory accesses for larger ip prefixes. Each of the prefix length memory tables is used to hold a set of forwarding rules associated with a different prefix length range.

Method for encoding and decoding integral images, device for encoding and decoding integral images and corresponding computer programs
An encoder and method of encoding are provided for encoding at least one integral image representing at least one object in perspective in a scene and including a plurality of elemental images. The method of encoding includes generating a plurality of k sub-images on the basis of the plurality of basic images; arrangement of the sub-images in a predetermined pattern such as to form a multi-view image of the object, the views corresponding respectively to the sub-images; and adaptive compression of the multi-view image formed, as a function of the motion type of the object in the scene..
