    Abstract: A method, a system, and a non-transitory storage medium provides to receive multicast protocol packets, wherein each of the multicast protocol packets includes one of a slice of program data of a Moving Picture Experts Group (MPEG) Dynamic Adaptive Streaming over Hypertext Transfer Protocol (HTTP) (MPEG-DASH) segment and a header of the slice that indicates sequence information of the slice relative to other slices, or forward error correction data; order, in response to the receipt of the multicast protocol packets, each slice received based on the sequence information; determine whether any slice is missing that is a part of the MPEG-DASH segment; determine, in response to a determination that that there are missing slices, whether the missing slices can be recovered; and use, in response to a determination that the missing slices can be recovered, the forward error correction data to recover the missing slices.

    Abstract: Content streams, such as video streams, may be seamlessly provided as both multicast and unicast transmissions. For example, in one implementation, a mobile device may receive a request, from a user of the mobile device, to play streaming content at the mobile device. The mobile device may receive, from a wireless network, and using multicast techniques, a sequence of content segments that correspond to the requested streaming content, and determine when a content segment is missing from the sequence of content segments. The mobile device may request, in response to the determination of the missing content segment, the missing content segment, from the wireless network, using unicast techniques; and insert the received missing content segment into the sequence of content segments to obtain the sequence of content segments as a sequence that includes content segments received using both multicast and unicast techniques.

    Abstract: A method, a system, and a non-transitory storage medium provides to receive a program including audio and video data; generate Moving Picture Experts Group (MPEG) Dynamic Adaptive Streaming over Hypertext Transfer Protocol (HTTP) (MPEG-DASH) segments that have multiple bit rates; transmit first packets that include the MPEG-DASH segments; divide each of the MPEG-DASH segments into first multiple slices of program data; generate a first header for each first slice of the first multiple slices, wherein the first header includes sequence information; multicast second packets that include first headers and the first multiple slices of each of the MPEG-DASH segments; assemble the MPEG-DASH segments; divide each of the MPEG-DASH segments into second multiple slices of the program data; encapsulate the second multiple slices into third packets; generate forward error correction packets; and multicast to a user device of a multicast, the third packets and the forward error correction packets.

    Abstract: In embodiments, apparatuses, methods and storage media are described that are associated with packaging of content. In embodiments, a bytemap file may be associated with an output packaging format for output content. The bytemap file may, in various embodiments, contain instructions that, when performed by a transpackager may generate output content based on one or more encoded content files. In order to generate output content starting at a specific requested offset, a bytemap index may contain mappings between offsets and instruction locations within the bytemap file. Thus, in response to a request for output content at an offset, an instruction location may be identified in the bytemap index, and instructions applied to the encoded content files starting at the identified location to generate the requested output content. Other embodiments may be disclosed and claimed.

    Abstract: Techniques described herein may allow for the flexible selection, and use of, various streaming techniques when a particular streaming technique is specified or required by a content player application. For example, some content player applications require the use of Hypertext Transfer Protocol Live Streaming (“HLS”). In some situations, other techniques, such as Moving Pictures Experts Group Dynamic Streaming over Hypertext Transfer Protocol (“MPEG-DASH”), may be preferable. The selection may be based on current operating conditions, such as whether a device, running the content player application, is using a WiFi or a cellular network. A local web proxy may be used to allow a content player application to request files using HLS, and may obtain the requested files using another streaming technique (e.g., MPEG-DASH). The obtained files may be transpackaged and provided to the content player application for presentation to a user.

    Abstract translation: 当特定的流技术被内容播放器应用指定或要求时，本文描述的技术可以允许灵活地选择和使用各种流技术。 例如，一些内容播放器应用程序需要使用超文本传输​​协议直播（“HLS”）。 在某些情况下，其他技术，例如运动图像专家组通过超文本传输​​协议动态流（“MPEG-DASH”）可能是优选的。 选择可以基于当前的操作条件，例如运行内容播放器应用的设备是否正在使用WiFi或蜂窝网络。 可以使用本地web代理来允许内容播放器应用使用HLS请求文件，并且可以使用另一个流技术（例如，MPEG-DASH）获得所请求的文件。 所获得的文件可以被转包并提供给内容播放器应用以呈现给用户。

    Abstract: In embodiments, apparatuses, methods and storage media are described that are associated with determination of frame alignment. In embodiments, a similarity value matrix may be determined representing similarity values for pairs of frames from two pieces of video content. An alignment score matrix may be determined from the similarity scores. Multiple sets of frames may be selected from the two pieces of video content and alignment score matrices determined for each set. From these alignment score matrices, an alignment of frames may be determined. In embodiments, a Needleman-Wunsch process may be used to compute alignment scores as well as to compute alignments based on alignment score matrices. Other embodiments may be described and claimed.
