Abstract: A method and apparatus for decoding multiple semantically independent picture parts into a single video picture includes decoding unique picture order count values for each coded picture, coded slice, or coded tile in a coded video sequence, with multiple decoded pictures, cycles, and tiles belonging to a same access unit representing a frame of the video. A value representing the amount of pictures, cycles, or tiles, is then assigned to each access unit for assigning sequential access unit count values to the access units. As a result, each access unit, which represents multiple pictures, slices, or tiles to be combined into a single frame, is decoded for display processing.

Abstract: Methods, apparatus, and computer readable media are described related to automated assistants that proactively incorporate, into human-to-computer dialog sessions, unsolicited content of potential interest to a user. In various implementations, based on content of an existing human-to-computer dialog session between a user and an automated assistant, an entity mentioned by the user or automated assistant may be identified. Fact(s)s related to the entity or to another entity that is related to the entity may be identified based on entity data contained in database(s). For each of the fact(s), a corresponding measure of potential interest to the user may be determined. Unsolicited natural language content may then be generated that includes one or more of the facts selected based on the corresponding measure(s) of potential interest. The automated assistant may then incorporate the unsolicited content into the existing human-to-computer dialog session or a subsequent human-to-computer dialog session.
