    摘要： A method of encapsulating an encoded bitstream representing one or more images includes providing description of images and/or sub-image picture, providing composed picture description, and outputting the bitstream. The description of images and/or sub-image pictures identifying portions of the bitstream representing the images and/or sub-images of the one or more images is provided. The composed picture description of at least one composed picture formed by one or more images and/or sub-image pictures also is provided. The bitstream, together with the composed picture description, is output as an encapsulated data file.

    摘要： The invention relates to encapsulating tiled timed media data in a server and providing a timed media data bit-stream from encapsulated tiled timed media in a client device. The tiled timed media data comprises timed samples and each timed sample comprises a plurality of spatial subsamples. After having selected at least one spatial subsample from amongst the plurality of spatial subsamples of one of the timed samples, one tile track comprising the selected spatial subsample and one corresponding spatial subsample of each of the other timed samples is created for each selected spatial subsample. One composite track comprising at least one extractor identifying at least one of the created tile tracks is created. Each created track is independently encapsulated in at least one media segment file.

    摘要： The invention relates according to one of its embodiments to a method for encapsulating a partitioned timed media data, the partitioned timed media data comprising timed samples, at least one timed sample comprising at least one subsample. The method comprising: obtaining at least one subsample from at least one of the timed samples; creating a first track comprising the at least one obtained subsample; obtaining at least another subsample from the same one of the timed samples; creating a second track comprising said at least another obtained subsample; and generating descriptive metadata, the descriptive metadata comprising a unified descriptor comprising: a first parameter which indicates, when set to 1, that the at least one obtained subsample is a complete frame; and at least a second parameter which specifies coding dependencies between the at least one obtained subsample and the at least another obtained subsample.

    摘要翻译： 本发明涉及将平铺的定时媒体数据封装在服务器中，并在客户端设备中从封装的平铺定时媒体提供定时的媒体数据比特流。 平铺的定时媒体数据包括定时样本，并且每个定时样本包括多个空间子样本。 在从定时样本之一的多个空间子样本中选择了至少一个空间子样本之后，为每个所选择的空间子样本创建包括所选择的空间子样本的一个瓦片轨迹和每个其他定时样本的一个对应的空间子样本。 创建包括至少一个提取器的复合轨道，该提取器识别创建的瓦片轨道中的至少一个。 每个创建的轨道被独立地封装在至少一个媒体段文件中。
