A differential media uploading system includes a hardware processor and a memory storing software code. The hardware processor executes the software code to receive a timeline file including a playlist track for a video file, and determine whether any pre-existing video frames stored in a media mastering system include a respective image depicted by a video frame contained in the video file. When it is determined that any of the pre-existing video frames include the respective image, the hardware processor executes the software code to disregard the video frame. When it is determined that none of the pre-existing video frames include the respective image, the hardware processor executes the software code to encode the video frame to provide an encoded video frame and upload the encoded video frame to the media mastering system.

Automation of differential media uploading

The present document describes a device and method for synchronizing a motion signal corresponding to a media content with a media signal for the media content, the motion signal being for controlling a motion feedback system. The method comprises: receiving a portion of the media signal; obtaining a fingerprint corresponding to the received portion of the media signal; from reference fingerprints associated with time positions of at least one reference media content, identifying a reference time position of the media content corresponding to the obtained fingerprint; obtaining the motion signal associated with the identified reference time position of the media content; and outputting the motion signal synchronized with the media signal using the identified reference time position of the media content for controlling the motion feedback system.

A bass management system and method for mitigating bass management errors by using explicit information available in the object audio rendering process and deriving the correct subwoofer contribution for each audio object. Embodiments of the bass management system and method are used to maintain the correct balance of the bass reproduced by the subwoofer relative to the sound coming out of the other speakers. The system and method are useful for a variety of different speaker configurations, including speaker configurations having different speaker sub-zones. Power-normalized gain coefficients for each speaker are combined and the power of the combined gain coefficients is computed and used to obtain a power-preserving subwoofer contribution coefficient. This subwoofer contribution coefficient is applied to the bass portion of the audio signal and audio objects to determine the contribution of a particular subwoofer.

Bass management for object-based audio

Embodiments of systems and methods are described for providing backwards compatibility for legacy devices that are unable to natively render non-channel based audio objects. These systems and methods can also be beneficially used to produce a reduced set of audio objects for compatible object-based decoders with low computing resources.

System for dynamically creating and rendering audio objects

Methods and systems of reproducing object-based audio are disclosed. In some embodiments, vector base amplitude panning (VBAP) is used for playing back an object's audio. Using the positioning of sound reproduction devices and object's location information, rendering can determine which sound reproduction devices are used for playing back the object's audio. For example, a triangle in which the object is positioned at a given time can be identified. The triangle can have sound reproduction devices as vertices, and the object's audio can be rendered on the sound reproduction devices corresponding to the vertices of the triangle. In some embodiments, ambiguities associated with VBAP-based rendering are identified and resolved.

In a digital cinema network of NTP-timekeeping devices in which one of the devices decodes video information, the scheduling of future instructions takes into account the differences between the nominal and actual frame rates of the video decoding device and the network's NTP latency.
