Abstract: Various approaches for coordinating edge computing transactions are described, based on the generation and verification of fine-grained timestamp values among distributed computing entities in an edge computing system. In an edge computing system, an edge computing device performs operations to obtain transaction data, a timestamp, and a timestamp signature for a transaction, with the timestamp generated from a secure (and attestable) timestamp procedure that is coordinated with another entity (including via a network-coordinated timestamp synchronization). This timestamp is verified by the device based on the timestamp signature and the transaction data for the transaction, and the transaction is conducted (e.g., using a value of the timestamp) at the device or elsewhere in the system based on successful verification.

Abstract: Techniques to output a media stream, capture a media stream, or synchronize the output or capture of the media stream at a specified time are described. A media stream output or capture apparatus may include a media processor to receive a media stream to output or a request to capture a media stream and a start time. A buffer generator may be included to generate an input or an output buffer and a media mixer may be included to mix the media stream into the output buffer at the start time or capture the media stream from the input buffer at the start time.

Abstract: An apparatus for time aware audio streams is described herein. The apparatus includes a converter and an alignment unit. The converter is to perform sample rate conversion of data from a first clock to a second clock. The alignment unit is to indicate valid sample points in the data based on a relationship between the first clock and the second clock.

Abstract: Methods and apparatus relating to measuring time offsets between devices with independent silicon clocks are described. In some embodiments, logic is provided to synchronize a first clock of a first agent with a second clock of a second agent based on one or more messages exchanged between the first agent and the second agent and a platform time. The first agent and the second agent are coupled via a link. Other embodiments are also disclosed and claimed.

Abstract: An embodiment may include circuitry to determine, at least in part, whether to delay transmission, at least in part, of at least one frame in favor of transmitting at least one other frame. The at least one other frame may belongs to at least one packet stream that is associated with at least one bandwidth reservation. The transmission of the at least one frame may be timed to occur prior to the transmitting of the at least one other frame. The at least one frame, at the time that it is selected for transmission, may have a relatively higher transmission priority than a relatively lower transmission priority of the at least one other frame. Many modifications, variations, and alternatives are possible without departing from this embodiment.

Abstract: An embodiment may include circuitry that may facilitate, at least in part, assignment, at least in part, of at least one bandwidth reservation for at least one packet stream and/or at least one stream reservation class. The at least one bandwidth reservation may be greater than an expected communication bandwidth of the at least one packet stream. The assignment of the at least one bandwidth reservation may be made prior to commencement of communication of the at least one packet stream. The at least one bandwidth reservation may be assigned exclusively to the at least one packet stream and/or the at least one stream reservation class. Many modifications, variations, and alternatives are possible without departing from this embodiment.

Abstract: A system and method for synchronizing simultaneous media stream playback across disjoint network timing/clock islands. An embodiment of a method includes determining a closest device to a source device in a network communications path between the source device and one or more target devices. Here, clocks of the closest device and the one or more target devices are synchronized and a clock of the source device is not necessarily synchronized with the clocks of the closest device and the one or more target devices. A current time for the closest device is then determined. A start time is assigned to at least the current time plus a maximum latency across the network communications path. A data stream and the start time are sent to the one or more target devices for rendering. Other embodiments are described and claimed.

Abstract: A device may be configured to receive data in a substantially continuous manner and to present the data to a user. The data may be presented to the user at different presentation rates including at least a first presentation rate and a second presentation rate. For example, the device may be configured to present the data at the first presentation rate until a threshold condition is satisfied, and to then present the data at the second presentation rate. In one embodiment, the first presentation rate may be a rate slower that normally used for the type of data received, which may allow the device to buffer some of the received data in a device memory. Once the amount of buffered data reaches a threshold level in the memory, the device may then increase to the second presentation rate (e.g., the presentation rate typically used for the type of data received).
