摘要： The invention is related to methods and apparatus that conceal errors in images of a corrupted video bitstream. One embodiment conceals errors in a missing or corrupted intra-coded macroblock by linearly interpolating data from other macroblocks that correspond to portions of the image above and below the missing or corrupted macroblock. One embodiment can utilize substitute motion vectors for a missing or corrupted predictive-coded macroblock. Another embodiment doubles the received motion vectors and references the doubled motion vectors to a previous-previous frame. Another embodiment adaptively selects which concealment or reconstruction technique is applied according to projected error estimates. Another embodiment conceals errors by replacing corrupted or missing data by combining concealment data in a weighted sum to reduce an estimated error.

摘要： The invention is related to methods and apparatus that recover usable video data from partially corrupted data. Embodiments inspect corrupted data packets and identify the location or locations of an error, whether the corrupted data packet contains data expected to be error-free, and whether the error-free data should be used. Decoding of a packet in both the forward direction and the backward direction can be used to locate a position of an error. Intra-coded macroblocks can also be recovered. A decoder can elect to use or to drop an intra-coded macroblock recovered from a corrupted data packet according to further criteria that is applied to the recovered intra-coded macroblock. One embodiment inspects video bitstream data that has been encoded with an optional data partitioning feature enabled, and retrieves specified data in areas of a corrupted packet that are expected to be free from error.

摘要： The present invention relates to a method for embedding a watermark into a black and white or color digital image [D(x)]. Basically the inventive method comprises the steps of transforming the digital image using a wavelet transform [WC(y)], transforming a watermark using discrete cosine transform (DCT), integrating the wavelet-transformed digital image with the DCT-transformed watermark [DW(x)+WC(y)] to insert the watermark into the image, and generating the watermarked image using inverse wavelet transform [D(x)′]. For color images, RGB mode is converted into YIQ mode using a conversion matrix and the wavelet transform is applied to the Y-, I-, Q-values. This inventive digital watermarking of a color image is found to be highly robust against lossy compression and other image processing operations, compared to conventionally known methods which are known to be unsuitable for watermarking color images.
摘要翻译：本发明涉及一种将水印嵌入到黑白或彩色数字图像[D（x）]中的方法。基本上，本发明的方法包括以下步骤：使用小波变换[WC（y）]变换数字图像，使用离散余弦变换（DCT）变换水印，将小波变换数字图像与DCT变换水印[DW x）+ WC（y）]将水印插入到图像中，并使用逆小波变换[D（x）']生成带水印的图像。对于彩色图像，使用转换矩阵将RGB模式转换为YIQ模式，并将小波变换应用于Y，I，Q值。发现彩色图像的本发明的数字水印技术对于有损压缩和其他图像处理操作来说是高度鲁棒的，与已知的不适合于对彩色图像进行水印化的已知方法相比。

摘要： A communication method in an IEEE 802.11 wireless LAN environment comprises: in the event that traffic from a station targeting another station as a destination is generated in the station, negotiating with another station for directly establishing a link to a secondary wireless channel other than the basic service set (BSS) channel used for communication with an access point (AP); if the negotiation has succeeded, and the link to the secondary channel is to be directly established, switching the operating channel of the station from the BSS channel to the secondary channel; and transmitting data of the generated traffic to said other station through the secondary channel. The method enables communication between the station and the AP, and the direct establishment of links between stations using multiple channels in an IEEE 802.11 wireless LAN environment.

摘要： A convertible computer is equipped with a notebook computer function and a tablet computer function. When a system power supply is turned on, a functionality or physical configuration such as rotation state of a display module can be detected, and an environment can be controlled such as an operating system (OS) for a tablet computer or notebook computer is selectively booted. Input signals of input units can also be controlled in an activation or inactivation state according to a system mode. An operation of switch sensing an open/closed state of a liquid crystal display (LCD) can be controlled by a signal generated by the rotation operation of the display module. In a state in which at least one control value necessary for setting a system environment is stored in a memory, the system mode switching operation is monitored and the system environment is set according to the switched system mode.
