    Abstract: Innovations for signaling state of a decoded picture buffer (“DPB”) and reference picture lists (“RPLs”). In example implementations, rather than rely on internal state of a decoder to manage and update DPB and RPLs, state information about the DPB and RPLs is explicitly signaled. This permits a decoder to determine which pictures are expected to be available for reference from the signaled state information. For example, an encoder determines state information that identifies which pictures are available for use as reference pictures (optionally considering feedback information from a decoder about which pictures are available). The encoder sets syntax elements that represent the state information. In doing so, the encoder sets identifying information for a long-term reference picture (“LTRP”), where the identifying information is a value of picture order count least significant bits for the LTRB. The encoder then outputs the syntax elements as part of a bitstream.

    Abstract: In one aspect of this disclosure, rounding adjustments to bi-directional predictive data may be purposely eliminated to provide predictive data that lacks any rounding bias. In this case, rounded and unrounded predictive data may both be considered in a rate-distortion analysis to identify the best data for prediction of a given video block. In another aspect of this disclosure, techniques are described for selecting among default weighted prediction, implicit weighted prediction, and explicit weighted prediction. In this context, techniques are also described for adding offset to prediction data, e.g., using the format of explicit weighted prediction to allow for offsets to predictive data that is otherwise determined by implicit or default weighted prediction.

    Abstract translation: 在本公开的一个方面中，可以有目的地消除对双向预测数据的舍入调整，以提供缺乏任何舍入偏差的预测数据。 在这种情况下，可以在速率 - 失真分析中考虑舍入和未被占据的预测数据，以识别用于预测给定视频块的最佳数据。 在本公开的另一方面中，描述了用于在默认加权预测，隐式加权预测和显式加权预测之间进行选择的技术。 在此上下文中，还描述了用于向预测数据添加偏移量的技术，例如，使用显式加权预测的格式以允许通过隐式或默认加权预测另外确定的预测数据的偏移量。
