Embodiment Construction

[0025] The description that follows includes sample systems, methods, and computer program products that implement various elements of the disclosure. However, it should be understood that the described disclosure may be practiced in a variety of forms other than those described herein.

[0026] The present disclosure discloses systems, computer program products and methods for synchronizing independent output streams, eg, to provide reminders with two or more component outputs. At least two output streams to be synchronized may be rendered with at least two independent renderers. Independent renderers are provided with a shared synchronization object when instructed to render individual output streams; this shared synchronization object may come from a synchronization component. The times at which all independent renderers can render respective first buffers of respective output streams (ie, "sync time") may be determined from the shared sync object. Rendering of the output...

Abstract

A system determines to use at least two independent renderers to render at least two output streams that are to be synchronized. The independent renderers are provided with a shared synchronization object when instructed to render the respective output stream. A time when all of the independent renderers can render a respective first buffer of the respective output stream is determined from the shared synchronization object. Rendering of the output streams utilizing the independent renderers is begun at the determined time. In this way, rendering of the output streams may be synchronized.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of US Patent Application Serial No. 14 / 292,690, filed May 30, 2014, entitled "Synchronization of Independent Output Streams," which is incorporated by reference as if fully disclosed herein. This application also claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 62 / 044,891, filed September 2, 2014, entitled "Synchronization of Independent Output Streams," which is incorporated by reference for It's as if it's fully disclosed here. technical field [0003] The present disclosure relates generally to streaming output, and more particularly to synchronization of independent output streams, which may correspond to different types of output, such as audio and haptic output. Background technique [0004] Electronic devices can render streams of audio to drive components such as speakers, actuators, and the like. Typically, such electronic device...
