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 novel amplifier for a wireless device is disclosed. The system employing the preferred embodiment can deliver a radio signal with output power up to 500 mW for 64QAM (48 Mb/s bit rate) modulation and a radio signal up to 700 mW for 16QAM (36 Mb/s bit rate) modulation with the packet error rate below 1%. The increase of the signal from 10 to 500 mW (64QAM modulation) thus increases the base station coverage area 50 times.

摘要： A method and system are provided for equalizing the loudness of an audio source. Initially, the perceptual loudness level of an audio signal is measured from one or more audio sources. Next, the loudness level of the audio signal is adjusted using the perceptual loudness level. Thereafter, the audio signal corresponding to the music selections is reproduced such that the perceived loudness to a listener is the same entirely throughout a music track corresponding to the music selections.

摘要： Adaptive entropy encoding and decoding techniques are described. For example, a screen capture encoder and decoder perform adaptive entropy encoding and decoding of palettized screen capture content in screen capture video. The encoder selects between different entropy encoding modes (such as an arithmetic coding mode and a combined run length/Huffman encoding mode, which allow the encoder to emphasize bitrate reduction at some times and encoding speed at other times). The run length encoding can use run value symbols adapted to common patterns of redundancy in the content. When the encoder detects series of pixels that could be encoded with different, alternative runs, the encoder selects between the alternative runs based upon efficiency criteria. The encoder also performs adaptive Huffman encoding, efficiently parameterizing Huffman code tables to reduce overall bitrate while largely preserving the compression gains of the adaptive Huffman encoding. A decoder performs converse operations.

摘要： A method and system are provided for improving the preferred listening environment of a sound system. Initially, a calibration pulse is generated from one or more rendering devices. Next, the calibration pulse is captured at a microphone attached to the rendering devices. Thereafter, one or more time delay, gain, and frequency response characteristics of the sound system are calculated using the captured calibration pulse. Based on these calculations, the time delay, gain, and frequency response characteristics of the rendering devices are adjusted respectively to cause the sound generated from the rendering devices to reach a listener's acoustic preference.
