Abstract: A method for decoding a video bitstream comprising a sequence of pictures comprising a picture A and a picture B, wherein picture A starts a recovery point period and picture B ends the recovery point period. The method includes obtaining the video bitstream and decoding from the video bitstream a normative indication of the recovery point period. The normative indication of the recovery point period indicates that picture A starts the recovery point period and/or that picture B ends the recovery point period.

Abstract: Methods to decode a picture from a bitstream are discussed. A partitioning structure of the picture is determined, wherein the partitioning structure defines at least first and second partitions of the picture. At least one dependency syntax element is decoded from the bitstream, and whether the second partition is dependent on or independent of the first partition is determined based on the at least one dependency syntax element. The picture is decoded from the bitstream based on determining whether the second partition of the picture is dependent on or independent of the first partition of the picture. Related methods of encoding and related devices are also discussed.

Abstract: A cooling arrangement for a vehicle engine including at least one cooling element which has flowing through it a gaseous medium operable to being cooled by an external air flow which flows in a specified direction through the cooling element during operation of the combustion engine. A heat-supplying element is fitted at a location upstream from the cooling element with respect to the direction of the cooling air flow so that at least part of the air flowing through the heat-supplying element also flows through the cooling element. A control device is operable to activate the heat-supplying element so that the air flowing through the heat-supplying element is warmed during situations where there is risk of the gaseous medium in the cooling element being cooled to below a lowest acceptable temperature. The heat-supplying element and the cooling element have a connection so that they constitute a composite unit.

Abstract: An air cooler comprises at least one tubular element with an inside surface which defines a passage for air which is to be cooled in the air cooler. At least one heat-conducting element is fastened inside the passage and is shaped to divide the passage into a plurality of flow paths between the inlet and the outlet of the passage. A medium at a lower temperature than the air to be cooled in the air cooler flows in contact with an outside surface of the tubular element cooling the air in the air cooler as the air is led through the passage. The heat-conducting element is sized such that it occupies only part of the cross-section of the passage in the direction of flow of the medium, thereby forming in a remaining portion of the passage in the direction of flow of the medium an elongate duct between the inlet and the outlet of the passage.
