Abstract: In one example, a device includes one or more processors configured to determine that a manifest file for media content indicates that the media content includes a first period and a second period, that the manifest file indicates that the first and second periods are continuous, and that advertisement media data is available for insertion between the first and second periods, select a first adaptation set in the first period based at least in part on characteristics signaled for the first adaptation set, retrieve media data of the first adaptation set based on the selection of the first adaptation set, retrieve the advertisement media data, and retrieve media data of a second adaptation set in the second period that the manifest file indicates is associated with the first adaptation set based on the selection of the first adaptation set and store the retrieved media data to a memory.

Abstract: A client device includes a memory comprising a buffer for buffering data having real-time constraints and a hardware-based processor comprising digital logic circuitry. The processor is configured to execute a real-time application configured to determine times during which the data will be available for download, determine a time at which the data is needed to prevent a buffer underrun for the buffer, and when the data is available, send a request for the data and deadline information representative of the time at which the data is needed to avoid the buffer underrun. In this manner, a sending device can prioritize delivery of the requested data to prevent the buffer underrun for the client device.

Abstract: An example device for processing media data is configured to parse a bitstream including the media data, the bitstream being formatted according to Common Media Application Format (CMAF), detect, during the parsing, a file type (FTYP) value for a CMAF track file of the bitstream, determine that a CMAF header of the CMAF track file starts with the FTYP value, and process one or more CMAF fragments following the CMAF header of the CMAF track file. The device may additionally be configured to detect one or more segment type (STYP) values in the bitstream, determine that each of the one or more STYP values corresponds to a start of a respective one of the CMAF fragments, and process each of the CMAF fragments starting from the corresponding STYP value.

Abstract: Systems and methods for delivery of opaque objects provided by a content provider to network nodes within a communication network are described. Opaque objects may comprise data objects whose data structure is not natively defined in the network interface and thus have a data type and/or structure that would be unknown to systems of the network. Communication systems may be configured according to embodiments to facilitate delivery of such opaque objects, such as by providing a robust network interface between a content provider system and the network through which network information is provided from the network to the content provider system and/or delivery manifest information for opaque objects is provided from the content provider system to the network.

Abstract: Content (e.g., multimedia streams, audio-video streams, video files, text, etc.) may be delivered to receiver devices over a broadcast channel and/or via a broadcast network via components (e.g., servers, receiver device, software applications, modules, processes, etc.) configured to communicate the content in a manner that reduces the amount of information communicated over the broadcast network, reduces the amount network bandwidth consumed by the communication, meets precise timing requirements for the individual objects that are communicated, and enables each receiver device to receive, decode, and render the content without consuming an excess amount of that receiver device's battery or processing resources.

Abstract: A method of transporting media data includes, by a file-based protocol sending unit of a source device, receiving a stream of data comprising Segments of media data from a segmenter of the source device that forms the Segments, each of the Segments comprising a respective individually retrievable file associated with a unique uniform resource locator (URL), determining locations of media delivery events (MDEs) in the stream of media data, wherein the MDEs include data for at least a portion of one of the Segments, determining one or more transmission time requirements for the MDEs representing times at which the MDEs are to be sent to a client device, and providing the MDEs and data representing the transmission time requirements to a physical layer sending unit of the source device according to available delivery slots for the physical layer sending unit.

Abstract: An example device for processing media data includes one or more processors configured to receive a file including media data, determine that a portion of the file is potentially erroneous, form error-indicative data indicating that the file includes the portion that is potentially erroneous, and store the file and the error-indicative data to a location available to a target application for the media data of the file. Another example device includes one or more processors configured to receive a file including media data, receive a first set of information indicative of one or more removable portions of the file that can be removed from the file, receive a second set of information indicative of a suspect portion of the file, determine one or more of the removable portions that completely overlap the suspect portion, and remove the determined one or more removable portions from the file.
