Abstract: In one example, a device includes one or more processors implemented in circuitry and configured to execute a Dynamic Adaptive Streaming over HTTP (DASH) aware application (DAA) and a DASH client, and one or more user interfaces. The DAA subscribes to DASH events of a DASH event stream via a first application programming interface (API) between the DAA and a DASH client executed by the one or more processors. The DAA then receives data for one or more DASH events of the DASH event stream from the DASH client via a second API between the DAA and the DASH client, the data for the one or more DASH events specifying interactivity-related content. The DAA then presents the interactivity-related content via the one or more user interfaces. The DAA may further send usage measurements on usage of the interactivity-related content to the DASH client, for reporting to a report server 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: An example device for decoding media data includes a memory configured to store the media data and one or more processors implemented in circuitry and communicatively coupled to the memory. The one or more processors are configured to determine whether two or more decoder instances are intended to be synchronized. The one or more processors are configured to, based on the two or more decoder instances being intended to be synchronized, control the two or more decoder instances so as to enable rendering of decoded data from each of the two or more decoder instances at a same presentation time.

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.
