摘要： Systems and methods for providing multi-channel audio using a reduced amount of resources for the decoding process. A 5.1 channel audio stream is divided into three stereo streams. The packets from each of three stereo streams are multiplexed to create a pseudo-5.1 channel audio stream. The pseudo 5.1 channel audio stream is then decoded and demultiplexed at the output to create the output 5.1 channel audio sound. As such, the decoder resources only have decode a single pseudo 5.1 stream. This technique is equally applicable to 7.1 or other multi-channel formats.

摘要： Video deblocking can be implemented in video content processing and delivery environments when displaying decompressed/decoded video information. Discontinuities are identified and smoothed to reduce blockiness, for example at macroblock boundaries in conjunction with Moving Picture Expert Group (MPEG)-based schemes. In exemplary implementation(s), a client device detects discontinuities at or near block boundaries, determines which discontinuities are artificial, and smooths at least those discontinuities that are determined to be artificial. These actions may be accomplished using (i) one or more Laplacian of Gaussian (LoG) operations as applied to both an image and a quantization matrix and (ii) windowed comparisons between values and a threshold resulting from the LoG operations. Alternatively, these actions may be accomplished using a spatio-temporally varying filter. Additionally, in an MPEG context, intra image units may be deblocked using the former approach while non-intra image units may be deblocked using the latter approach.
摘要翻译：当显示解压缩/解码的视频信息时，视频解锁可以在视频内容处理和传送环境中实现。不连续性被识别和平滑以减少块效应，例如在与基于运动图像专家组（MPEG）的方案的宏块边界处。在示例性实现中，客户端设备在块边界处或附近检测不连续性，确定哪些不连续性是人为的，并且平滑至少那些被确定为人为的不连续性。可以使用（i）应用于图像和量化矩阵的一个或多个拉普拉斯高斯（LoG）操作来实现这些动作，以及（ii）值之间的窗口比较和由LoG操作产生的阈值。或者，可以使用时空变化滤波器来实现这些动作。另外，在MPEG上下文中，可以使用前一种方法去除帧内图像单元，而使用后一种方法可以解除非帧内图像单元。

摘要： An extension to the Universal Serial Bus (USB) protocol that utilizes reserved bits in the OHCI Endpoint Descriptors to signal which root hub port(s) should transmit the data. Typically, all ports transmit (broadcast) data. The present invention encodes transmission information that can be used by the hardware to effectively control which port(s) need to be tri-stated. However, by setting, the “on” bits for all the ports, the present invention retains standard USB functionality. Also provided is a method to increase the bandwidth of low speed devices connected to the USB bus by increasing the data payload for such devices.

摘要： Subject matter includes exemplary methods of reversible diffusion-based compression and an exemplary compression engine. In one implementation, a reversible diffusion function is applied to decrease high spatial frequency pixel values in an image or a prediction error image residue and to smooth variances between adjacent pixel values. An exemplary reversible diffusion function can increase data compression without loss of high frequency information yet operate with online encoders and decoders that lack significant processing power. An exemplary method transforms the data to make the data more amenable to compression schemes that utilize entropy transforms as an intermediate processing step, for example, prior to Huffman coding.
摘要翻译：主题包括可逆扩散式压缩的示例性方法和示例性压缩引擎。在一个实现中，应用可逆扩散函数来减小图像中的高空间频率像素值或预测误差图像残差，并平滑相邻像素值之间的方差。示例性的可逆扩散功能可以增加数据压缩，而不会损失高频信息，而与在线编码器和缺乏显着处理能力的解码器一起工作。例如，在霍夫曼编码之前，示例性方法转换数据以使数据更适合于利用熵变换作为中间处理步骤的压缩方案。

摘要： Power is dynamically conserved in a device by analyzing past processing performance of the device and predicting the amount of power required for future execution. In an example embodiment, a video frame is analyzed to determine what portion of the video frame was needed to render data. If less than the full video frame was needed, at least one power conservation technique is applied to the device for subsequent rendering of data. Power conservation techniques include adjusting the operating frequency of circuitry utilized to render data, adjusting the voltage applied to circuitry utilized to render data, and/or turning off/on circuitry utilized to render data.

摘要： A handheld gaming device having a non-removable hard disk drive memory is used to perform gaming and non-gaming functions. The hard disk drive memory provides internal mass storage that is utilizable for storing various types of game-related information and non-game-related information. In one embodiment, the hard disk drive is configured to store selected portions of data in assigned regions of memory. The internal mass storage can be used to store saved game data, game specific data, and can be used as a buffer while streaming content from a remote server or drive. The internal mass storage also can be used to store other types of information, such as calendar information, personal appointments, maps, photographs, and other third party game related information.
