摘要： An embodiment of a system to synchronize data streams is described. During operation, the system receives a first data stream having a first data type and performs a sequence of operations on at least a portion of the first data stream. Next, the system stores metadata associated with the first data stream one or more times during the sequence of operations. Metadata can include a time stamp, data-stream information associated with the portion of the first data stream, and event information associated with the occurrence of one or more events during the sequence of operations. Moreover, the system provides a notification based on the stored metadata, the notification to facilitate synchronizing the first data stream with a second data stream having a second data type.

摘要： Embodiments of a system that reduces power consumption by power-gating media decoders are described. During operation of the system, a decoder circuit receives encoded audio data and outputs corresponding decoded audio data to a memory, which is electrically coupled to the decoder circuit. Moreover, control logic, which is electrically coupled to the memory and the decoder circuit, provides commands to the memory and the decoder circuit that selectively disable at least a portion of the memory based on an amount of decoded audio data in the memory.

摘要： Devices and methods for power management during media playback are provided. For example, an electronic device according to an embodiment may include storage, a decoder, an output buffer, and data processing circuitry. The storage may store compressed media data that may be decoded by the decoder. The output buffer may store the decoded media data before the decoded media data is played out. The data processing circuitry configured may measure a fullness of the output buffer and may set an operating frequency of the storage, the decoder, the output buffer, or the data processing circuitry, or a combination thereof, depending on a format of the compressed media data and the fullness of the output buffer.

摘要： Systems, methods, and computer-readable media for efficiently coding and processing image data using an electronic device are provided. While both image-quality processing and coding operations may be performed for a frame of captured image data, the electronic device may leverage information generated during one operation in order to more efficiently conduct another operation. For example, an image coding operation may be performed on a first frame of image data by partitioning the image data into blocks of data and transforming the blocks of data into a frequency domain representation or format. Color component statistics from one or more of the blocks of data may be obtained, and an image-quality processing operation may then be performed on the first frame of image data or a subsequent frame of image data using the obtained color component statistics.

摘要： Systems, methods, and devices are provided for performing audio processing operations, such as crossfading between two audio streams, by storing information on multiple memories. In one example, such a method may include storing a first portion of information associated with an audio processing operation on a first memory. A second memory may be activated, upon which a second portion of the information associated with the audio processing operation may be stored. The audio processing operation may be performed using a processor with the information stored on the first memory and the second memory. When the audio processing operation has completed, the second memory may be deactivated.

摘要： Techniques are presented for dynamically controlling an audio crossfade from a first audio track to a second audio track. The first audio track may be decoded and buffered to a first buffer. A user may select a second audio track at some point during playback of the first audio track. The second audio track may be decoded, and a processor may access the decoded second audio track and the buffered first audio track and mix the two audio tracks. The mixed audio track may be inserted in the same first buffer near or at the read pointer of the first buffer, such that latency between the user selection and the crossfade into the selected audio track may be minimized. The insertion of the mixed audio track may depend on various factors, including the type of audio file and/or the decoder type used to decode the second audio track.

摘要： This is directed to processing voice inputs received by an electronic device while prompts are provided. In particular, this is directed to providing a sequence of prompts to a user (e.g., voice over prompts) while monitoring for a voice input. When the voice input is received, a characteristic time stamp can be identified for the voice input, and can be compared to periods or windows associated with each of the provided prompts. The electronic device can then determine that the prompt corresponding to a window that includes the characteristic time stamp was the prompt to which the user wished to apply the voice input. The device can process the voice input to extract a user instruction, and apply the instruction to the identified prompt (e.g., and perform an operation associated with the prompt).
