Abstract: A stereo sound decoding method and system decode left and right channels of a stereo sound signal, using received encoding parameters comprising encoding parameters of a primary channel, encoding parameters of a secondary channel, and a factor ?. The primary channel encoding parameters comprise LP filter coefficients of the primary channel. The primary channel is decoded in response to the primary channel encoding parameters. The secondary channel is decoded using one of a plurality of coding models, wherein at least one of the coding models uses the primary channel LP filter coefficients to decode the secondary channel. The decoded primary and secondary channels are time domain up-mixed using the factor ? to produce the decoded left and right channels of the stereo sound signal, wherein the factor ? determines respective contributions of the primary and secondary channels upon production of the left and right channels.

Abstract: Methods, systems, and devices for wireless communications are described. A network node may identify a set of packets (e.g., from a packet pool) that are scheduled for broadcast to a plurality of user equipments (UEs) and transmit a set of network encoded packets based on the set of packets. The network node may receive feedback from one or more of the plurality of UEs, and the feedback may indicate successfully decoded packets by each of the one or more UEs. Based on the feedback, the network node may identify an updated set of packets and transmit the updated set. The transmitter may continue to update and transmit based on feedback until the feedback indicates that updated set of packets is empty.

Abstract: A method, computer program, and computer system is provided for encoding or decoding video data. Video data including a chroma component and a luma component is received. A first coding tree structure associated with the luma component and a second coding tree structure associated with the chroma component are determined, wherein the first coding tree structure and the second coding tree structure share a same top level coding tree structure. The video data is decoded based on the first coding tree structure and the second coding tree structure.
