TL;DR: This paper presents an evaluation of constrained and unconstrained HEVC tiling compression, and also of the associated packaging and streaming overheads, and provides the interesting benefit of being able to deliver UHD videos over bandwidth-constrained networks adaptively, based on its tiled content.
Abstract: Adaptive streaming technologies are used heavily to deliver video content over the Internet, but still face problems in networks with limited bandwidth, for videos with ultra-high definition (UHD) or greater, even when using the latest High-Efficiency Video Coding (HEVC) standard. In this paper, we propose a solution to these problems based on three things: a specific HEVC-compliant motion-constrained tiled encoding allowing tile-based decoding and rendering; a specific derivation of the ISO base media file format enabling a tile-based encapsulation and delivery; and their use in adaptive streaming of tiled video content using MPEG dynamic adaptive streaming over HTTP requiring only a single standard HEVC decoder on the client side. We present an evaluation of constrained and unconstrained HEVC tiling compression, and also of the associated packaging and streaming overheads. The results of this evaluation indicate that our approach incurs a complete overhead of at most 7.3% for UHD content, at 10 Mbps or above, when split in 25 tiles, and only 3.5% for nine tiles, when compared with the streaming of the non-tiled video. Our approach also comes with a small impact on client-side players but provides the interesting benefit of being able to deliver UHD videos over bandwidth-constrained networks adaptively, based on its tiled content.

19 Aug 2008TL;DR: In this paper, a method of organizing streamed data includes storing streamed data in a file, identifying metadata applicable to a subset of the streamed data, and forming at least one group of one or more samples of the stream data, each sample in a group having identical metadata content for a metadata type.
Abstract: A method of organizing streamed data includes storing streamed data in a file, identifying metadata applicable to a subset of the streamed data, and forming at least one group of one or more samples of the streamed data, each sample in a group having identical metadata content for a metadata type. The file may be in accordance with ISO base media file format. The storing streamed data in a file may include storing in a reception hint track. The at least one group may be indicated in a sample group description box. The metadata type may be indicated by a grouping type and grouping instance data, the grouping type specifying semantics of the grouping instance data and the metadata content. The metadata content may comprise a metadata payload and zero or more metadata payload extensions, where the metadata payload is included in a first structure and the zero or more metadata payload extensions are included in a second structure.

TL;DR: The MPEG Media Transport (MMT) standard is being developed with specifications for encapsulation, delivery, and signaling, which enable fine-grained content access with uniquely identifiable names for optimized content delivery.
Abstract: Content-centric networking promises more efficient distribution of data through in-network caching and the propagation of content through the network. This networking paradigm poses a number of challenges and new opportunities for more efficient multimedia delivery. The MPEG Media Transport (MMT) standard is being developed to address these needs with specifications for encapsulation, delivery, and signaling, which enable fine-grained content access with uniquely identifiable names for optimized content delivery.

24 May 2010TL;DR: In this article, a video coding apparatus may be configured to utilize media extractors in a media extractor track that reference two or more non-consecutive network access layer (NAL) units of a separate track.
Abstract: A video coding apparatus may be configured to utilize media extractors in a media extractor track that reference two or more non-consecutive network access layer (NAL) units of a separate track. An example apparatus includes a multiplexer to construct a first track including a video sample comprising NAL units, based on encoded video data, wherein the video sample is included in an access unit, construct a second track including an extractor that identifies at least first one of the NAL units in the video sample of the first track, and wherein the extractor identifies a second NAL unit of the access unit, wherein the first identified NAL unit and the second identified NAL unit are non-consecutive, and include the first track and the second track in a video file conforming at least in part to ISO base media file format. The identified NAL units may be in separate tracks.
