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 driven by a host player device with video output from a head-mounted display (HMD) player device, the method comprising:
- establishing a session between the host player device and the HMD player device, wherein the host player device is coupled to an external sound system and the HMD player device comprises a video output system;
- determining, by at least one of the host player device or HMD player device, a latency period between audio output from the external sound system and corresponding video output from the HMD player device, wherein the determining is based on both the host and HMD player devices simultaneously initiating play of test content;
- providing, by the host player device, both the host and HMD player devices with access to identical digital audio-video content selected by a user;
- initiating play of the digital audio-video content by the host player device for audio output by the external sound system;
- and
- initiating play of the digital audio-video content by the HMD player device after waiting for the latency period so that audio output by the external sound system is synchronized with video output from the HMD player device.
An apparatus for synchronizing audio output by an external sound system driven by a host player device with video output from a head-mounted display (HMD) player device, comprising at least one processor coupled to a memory, the memory holding program instructions, that when executed by the at least one processor, cause the apparatus to perform:
- establishing a session between the host player device and the HMD player device;
- determining a latency period between audio output from the external sound system and corresponding video output from the HMD player device;
- providing both the host and HMD player devices with access to identical digital audio-video content selected by a user;
- initiating play of the digital audio-video content for audio output by the external sound system;
- and
- causing play of the digital audio-video content to be initiated by the HMD player device after waiting for the latency period so that audio output by the external sound system driven is synchronized with video output from the HMD player device.
