    Abstract: Innovations in control and use of chroma quantization parameter (“QP”) values that depend on luma QP values. More generally, the innovations relate to control and use of QP values for a secondary color component that depend on QP values for a primary color component. For example, during encoding, an encoder determines a QP index from a primary component QP and secondary component QP offset. The encoder maps the QP index to a secondary component QP, which has an extended range. The encoder outputs at least part of a bitstream including the encoded content. A corresponding decoder receives at least part of a bitstream including encoded content. During decoding, the decoder determines a QP index from a primary component QP and secondary component QP offset, then maps the QP index to a secondary component QP, which has an extended range.

    Abstract: Innovations in signaling of reference picture list (“RPL”) modification information. For example, a video encoder evaluates a condition that depends at least in part on a variable indicating a number of total reference pictures. Depending on the results of the evaluation, the encoder signals in a bitstream a flag that indicates whether an RPL is modified according to syntax elements explicitly signaled in the bitstream. A video decoder evaluates the condition and, depending on results of the evaluation, parses from a bitstream a flag that indicates whether an RPL is modified according to syntax elements explicitly signaled in the bitstream. The condition can be evaluated as part of processing for an RPL modification structure that includes the flag, or as part of processing for a slice header. The encoder and decoder can also evaluate other conditions that affect syntax elements for list entries of the RPL modification information.

    Abstract: One or more techniques and/or systems are disclosed for generating improved planar panorama imagery, which may be used to view street-level, human-scale locations along a desired path, for example. One or more desired objects can be detected in source imagery that may be used to produce the resulting planar panorama imagery. Respective object regions comprising a desired object can be identified in one or more frames of the source imagery. One or more portions of the source imagery that do not comprise the object region for the desired object can be joined with at least some of the one or more frames that do comprise the object region for the desired object. The resulting planar panorama imagery can thus comprise the desired object. Also, the planar panorama imagery can be generated so as to lack one or more non-desired objects and/or adverse effects that may result therefrom.
