Abstract: An image encoder or decoder includes circuitry and a memory coupled to the circuitry. The circuitry, in operation, predicts a first set of samples for a first partition of a current picture with one or more motion vectors including a first motion vector and predicts a second set of samples for a first portion of the first partition with one or more motion vectors from a second partition different from the first partition. The samples of the first set of samples of the first portion of the first partition and of the second set of samples of the first portion of the first partition are weighted. A motion vector for the first portion of the first partition is stored which is based on one or both of the first motion vector and the second motion vector. The first partition is encoded or decoded using at least the weighted samples of the first portion of the first partition.

Abstract: A method of video decoding is provided. In the method, a coded video bitstream of a current picture is received. The current picture is divided into a plurality of rows of coding tree units (CTUs). Coding blocks in a first CTU row of the plurality of rows of CTUs are decoded based on motion vector information stored in a history-based motion vector prediction (HMVP) buffer. The motion vector information stored in the HMVP buffer is updated as the coding blocks in the first CTU row are decoded. The HMVP buffer is updated to include the motion vector information of the coding blocks in a first CTU of the first CTU row after the coding block at an end of the first CTU row is decoded.

Abstract: A system and method for determining the performance of a video codec for real-time communication applications. A set of network conditions is used to simulate certain typical real-world network conditions. A coded video stream is transmitted from the transmitting end to the receiving end under these conditions. The end-to-end latency and received video fluency are measured along with a set of existing video quality measures by a video codec performance evaluation system including a network model and a video codec quality analyzer. The decodable frame ratio, latency and video fluency are used as the performance metrics for real-time communication video quality evaluation. The video codec performance evaluation system does not send any video data over a network when it determines the real-time communication quality of the video codec.

Abstract: A method for direct write printing of an electrical or optical element based upon a generated master actual position map and a master expected position map is disclosed. The generated master actual position map is generated by efficiently stitching together a number of images using a hierarchical stitching process.

The direct write printer then direct write prints the electrical or optical element using the generated toolpath. By using different types of inks, the electrical element may be a trace, a resistor, an inductor, a transformer, a capacitor, or some combination thereof. In like manner, the optical element may be a waveguide, a beam-splitter, a phase shifter, an optical attenuator, an interferometer, or some combination thereof.

A set of the sub-picture bitstreams and the mergeable indication are transmitted toward the decoder to support decoding and displaying a virtual reality video viewport.
