摘要： Described techniques and tools include techniques and tools for mapping digital media data (e.g., audio, video, still images, and/or text, among others) in a given format to a transport or file container format useful for encoding the data on optical disks such as digital video disks (DVDs). A digital media universal elementary stream can be used to map digital media streams (e.g., an audio stream, video stream or an image) into any arbitrary transport or file container, including optical disk formats, and other transports, such as broadcast streams, wireless transmissions, etc. The information to decode any given frame of the digital media in the stream can be carried in each coded frame. A digital media universal elementary stream includes stream components called chunks. An implementation of a digital media universal elementary stream arranges data for a media stream in frames, the frames having one or more chunks.

摘要： A surround experience for headphones can be created using various techniques and tools. The described techniques and tools can be applied separately or in combination. For example, a surround experience can be created by splitting input audio channel signals into high-pass and low-pass signals. The low-pass signals can undergo cross-mixing and artificial reverberation. The artificial reverberation can apply different delay profiles to the low-pass audio signals. The high-pass and low-pass audio signals can be combined to generate output audio channel signals. A surround experience can be crated using a system comprising an input module, a crossover module, a channel cross-mixing module, a reverberation module, and an adder module.

摘要： The present disclosure relates to playback of video/audio streaming media data to provide a substantially glitch-free experience. The system adapts the media stream to the user connection in order to choose the most desirable stream to avoid glitches. For example, in the case where there is interference (e.g., a microwave being used near a wireless device), the quality of the media stream is lowered. In one embodiment, an index file is used to make logical decisions about which media stream to choose in order to minimize glitches. The index file can take different forms, but, generally, includes characteristics about the available media streams. Example characteristics include the bit rates of the media streams and quality information about the media streams.

摘要： A compressed digital audio signal is transmitted from an audio source along a connection wire to an audio receiver. The digital audio signal can encode digital audio data having different sampling frequencies, frames sizes, and other information. The audio receiver that receives the digital audio signal can decode and convert the compressed digital audio signal into multiple synchronized analog signals, which are used to drive multiple speakers. The audio receiver may also synchronize the audio data with associated video data so that the audio playback and video playback are “in sync”, despite delay introduced by the audio signal decoding at the audio receiver.

摘要： An indexed file layout, comprising index information, is defined for segmented streaming of multimedia content. The index information can comprise program description information and streaming segment index information. In addition, the layout can comprise files containing streaming segments of the program, where the streaming segments are each encoded at one or more bitrates independently of other streaming segments of the program. The layout supports client switching between different bitrates at segment boundaries. Optimized client-side rate control of streaming content can be provided by defining a plurality of states, selecting available paths based on constraint conditions, and selecting a best path through the states (e.g., based on a distortion measure). In one client-side rate control solution states correspond to a specific bitrate of a specific streaming segment, and in another client-side rate control solution states correspond to a measure of client buffer fullness.
摘要翻译：包括索引信息的索引文件布局被定义用于多媒体内容的分段流。索引信息可以包括节目描述信息和流分片索引信息。此外，布局可以包括包含程序的流片段的文件，其中流片段每个以独立于节目的其他流片段的一个或多个比特率进行编码。该布局支持在段边界处的不同比特率之间的客户端切换。可以通过定义多个状态，基于约束条件选择可用路径以及选择通过状态的最佳路径（例如，基于失真度量）来提供流内容的优化的客户端速率控制。在一个客户端速率控制解决方案中，状态对应于特定流分段的特定比特率，并且在另一客户端速率控制解决方案状态对应于客户端缓冲区充满度的度量。

摘要： A low computational power digital audio player achieves beat continuous transitioning between digital audio pieces based on beat metadata, which can be generated via offline processing on a higher computational power computer or via background or idle processing on the digital audio player. The digital audio player produces playlists of beat matching compatible songs based on the metadata, or pick lists of songs that are beat matching compatible with a currently playing song. By facilitating selection of songs with beat matching compatible tempos based on metadata, the beat continuous transitions can be achieved without altering the beat tempo of digital audio pieces, or with simple resampling.

摘要： Bass frequencies of audio can be boosted using various techniques and tools. The described techniques and tools can be applied separately or in combination. For example, bass frequencies of audio can be boosted using an integer bass boost filter by receiving user-settable parameters, such as “c” and “s” coefficients, and implementing the integer bass boost filter using a coupled form structure implementation and the user-settable parameters. Bass frequencies of audio can also be boosted using an integer bass boost filter that is configured to use any of plural coupled form structure implementations. Bass frequencies of audio can be also be boosted using a linear combination of an input audio signal and output of a high-pass filter.
