Abstract
An apparatus and method for simultaneous output of video from a head-mounted display device and audio output from an external sound system includes compensating for latency in the external sound system relative to the head-mounted display. The latency is measured by outputting test content using one of alternative methods.
Claims20
A method for synchronizing audio output by an external sound system with video output from a display device, the method comprising:
- establishing a wireless communication session between a host device and the display device;
- determining a latency period between audio output from the external sound system and corresponding video output from the display device;
- providing both the host device and the display device with access to identical digital content;
- initiating play of the digital content by the host device for audio output by the external sound system;
- and
- initiating play of the digital content by the display device after waiting for the latency period.
3 more elements
A content synchronization system comprising:
- a host device configured to output audio to an external sound system;
- at least one display device configured to output video;
- a wireless network connecting the host device and the at least one display device;
- wherein the host device is configured to:
- manage distribution of digital content to the at least one display device,
- determine device-specific latency values for each display device, and
- coordinate synchronized playback accounting for the device-specific latency values.
4 more elements
An apparatus for coordinating multimedia playback across multiple devices, comprising:
- at least one processor;
- a memory storing instructions that, when executed, cause the apparatus to:
- establish communication sessions with one or more remote playback devices, analyze latency characteristics between audio and video output paths, distribute multimedia content to the remote playback devices, and synchronize playback timing across all devices based on the analyzed latency characteristics.
