Abstract: Embodiments help to provide a cross-device security schema for an audio device and a master device to which it is tethered (e.g., a smartphone). An example security scheme provides flexible mechanisms for locking and unlocking the audio device and the device to which it is tethered. For instance, an example security scheme may include: (a) an unlock sync feature that unlocks the audio device and keeps the audio device unlocked whenever the master device is unlocked, (b) a separate audio device unlock process that unlocks the audio device only (without unlocking the master device, and (c) an on-head detection process that, in at least some scenarios, locks the audio device in response to a determination that the audio device is not being worn.

Abstract: A system and method provides transcoding a video in parallel by multiple transcoders based on a measure of video coding complexity (VCC). The system has a video pre-processing module, a master transcoder, a transcoding controller and multiple transcoders. The video pre-processing module transcodes a source video into an intermediate video. The master transcoder partitions the intermediate video into multiple transcoding units, where a transcoding unit identifies a portion of data of the intermediate video for transcoding. The master transcoder further generates a transcoding request for each transcoding unit. The transcoding controller distributes the transcoding units to the multiple transcoders, which transcode the data of the transcoding units in parallel into transcoded data.

Abstract: An adaptive resolution transcoding system and method adaptively transcodes a source video with an optimized resolution and visual quality based on the video coding complexity (VCC) of the source video. The transcoding system is configured to receive a source video in its native format, and to obtain the video coding complexity score of the source video from a video coding complexity engine. The transcoding system is further configured to set a resolution adjustment level based on the complexity score. Based on the resolution adjustment level, the transcoding system determines an optimal output resolution for the source video for each video output format supported by the transcoding system. Responsive to a user selection of video output format, the transcoding system determines an optimal output resolution for the source video and encodes the source video with the determined optimal output resolution.

Abstract: A relative quality score is provided that takes into account properties of an encoded version of a source video. For example, one such quality score calculates a difference of higher and lower quality transcoded versions of the source video, and computes quality metrics for each to evaluate how similar the transcoded versions are to the source video. A relative quality score quantifying the quality improvement of the high-quality version over the low-quality version is computed. The relative quality score is adjusted based on a measurement of the quality of the source video. If the relative quality score for the video indicates a sufficient quality improvement of the high-quality version over the low-quality version, various actions are taken, such as retaining the high-quality version, and making the high-quality version available to users, e.g. via a video viewing user interface.

Abstract: A system and method provides content-adaptive bitrate video transcoding of a source video for a video hosting service. The system is coupled to a video coding complexity engine and video rate-distortion modeling engine of the video hosting service. The system is configured to receive the video coding complexity score of the source video and a trained rate-distortion model and a scaling model. A target bitrate estimation module of the system is configured to calculate an initial target bitrate based on the video coding complexity using the trained rate-distortion model. A bitrate refinement module of the system is configured to adjust the initial target bitrate with respect to the resolution and/or frame rate of the transcoded source video. An adaptive video coder of the system is configured to transcode the source video with the adjusted target bitrate.

Abstract: A system and method provide a video coding system for adaptively transcoding videos based on video coding complexity (VCC). A VCC engine of the system is configured to generate a measure of how difficult to encode a source video based on a trained VCC model. A video rate-distortion modeling engine of the system is configured to estimate a rate-distortion model and a scaling model.

The trained VCC model, rate-distortion model and the scaling model are used by an adaptive bitrate transcoding sub-system to transcode a source video with an optimized bitrate and visual quality. The trained VCC model, rate-distortion model and the scaling model are further used by an adaptive resolution transcoding sub-system to transcode a source video with an optimized resolution and visual quality.
