Abstract: 動画配信サーバ12は同じ空間を表す複数の動画像のデータをストリーミング転送する。動画再生装置10は動画像のいずれかから音声データを分離し、所定時間だけ遅延させて出力するとともに、別の動画像から画像データを分離し、音声と同期させて出力する。ユーザが画像の切り替え操作を行うと、動画再生装置10は切り替え後の動画像のデータを取得し、画像データを分離して、継続して出力している音声データと同じPTSで出力を開始する。

Abstract: The embodiments relate to methods and apparatuses for coding volumetric video. A method for encoding comprises receiving (610) a video presentation frame, where the video presentation represents a three-dimensional data; generating (620) one or more patches (410) from the video presentation frame, wherein the patches represent different parts of the content of the video presentation frame; determining (420, 630) which patch(es) of the generated one or more patches are to be encrypted (440), wherein the determination is based on a content of the patch; encrypting (440, 640) the determined patches with an encryption method that corresponds to a pre-defined authorization level; and encoding (450, 650) into a bitstream of a corresponding patch, information on the used encryption method.

Abstract: The disclosure provides for use of watermarking as a basis control abandonment of dynamic content modification. Upon detecting of the occurrence of a trigger event for causing a content presentation device to abandon a dynamic content modification with respect to a media stream being delivered to the content presentation device, an entity encodes into the media stream an abandonment-watermark interpretable by the content presentation device to cause the content presentation device to abandon the dynamic content modification. The content presentation device then detects the abandonment-watermark in the media stream being received by the content presentation device and in response to the abandonment-watermark, abandons the dynamic content modification.
