摘要： Video data is received in 2D or 3D format from different channels as a user scrolls through an electronic guide. The video data may be displayed in a portion of the on: screen display along with graphic and text associated with the EPG data. The received video data may be converted to a suitable format to be displayed with the Electronic Program Guide (EPG). The video data may be converted from 3D to 2D format to be displayed with the EPG data. The video data may be converted from 2D format to 3D format, while the EPG data displays in 2D format. The video data may be converted from one 3D format to another 3D format for display with the EPG data. Selection of converting the received video data can be based on a display format of a previously viewed channel prior to requesting the EPG to be displayed.

摘要： Data are received at a receiving device from a server, where the data are encoded into one of a plurality of different versions, each version having a different fidelity level. A data stream having a buffer with an initial maximum window size for buffering received data is requested from the server, wherein the data stream initially has a first fidelity level. The maximum window size is managed to prevent the current window size from falling below a threshold that might trigger an adjustment by the server in the fidelity level of the data stream sent by the server, unless and until the accumulation of data in the buffer due to a decrease in the present processing capabilities of the controller of the receiving device falls below a threshold of processing power necessary for processing the data stream at the higher fidelity level for more than a transitory period of time.

摘要： A content moving device which enables providing content stored on a first user device, such as a DVR, in a first format and resolution to be provided to a second user device, such as a portable media player (PMP) in a second format and resolution. The content moving device identifies content on the first user device as candidate content which may be desired by the PMP and receives the candidate content from the DVR. The content moving device transcodes the candidate content at times independent of a request from the PMP for the content. The content moving device may provide a list of available transcoded content to the PMP for selection, and provide selected content to the PMP. The content moving device may also provide information relating to any protection schemes of the content provided to the PMP, such as DRM rights and decryption keys. The content moving device performs the often computationally intense and time consuming transcoding of user content to enable the user to move content between different user devices in a convenient manner.

摘要： A three-dimensional (3D) video encoder includes a first encoder, a second encoder, and a multiplexer. The first encoder is configured to encode a base view to form a first independently compressed video stream associated with video content. The second encoder is configured to encode a nonbase view to form a second independently compressed video stream associated with the video content. The multiplexer is configured to multiplex the first and second independently compressed video streams associated with the video content to form a transport stream. The transport stream is operable to be processed to render a 3D video using the base and nonbase views.

摘要： A sampling rate converter for converting an input digital signal, such as D2 PAL, into an output digital signal, such as D1 PAL, has a pair of polyphase filters. The input digital signal is input in parallel to the two polyphase filters, with the phase selected by one of the filters being offset by one from that of the other. The outputs of the polyphase filters are input to a linear interpolator to produce the output digital signal. The resolution of the sampling rate conversion is a function of the number of phases N of the polyphase filters and the number of interpolation steps M of the interpolator.

摘要： A technique for reducing the number of coefficients in a low ratio sampling rate converter divides each input sampling rate interval into a plurality of bins. For each bin a set of conversion coefficients is computed. So long as output data samples lie within the same bin, the same set of coefficients is applied. When the output data samples move to another bin, the set of coefficients applied is changed. Thus a finite set of coefficients are computed rather than computing an exact set for each output data sample.
摘要翻译：用于减少低比率采样率转换器中的系数数量的技术将每个输入采样率间隔分成多个箱。对于每个仓，计算一组转换系数。只要输出数据样本位于同一个仓内，就应用相同的系数集。当输出数据样本移动到另一个bin时，应用的系数组被改变。因此，计算一组有限系数，而不是计算每个输出数据样本的精确集合。

摘要： A method of detecting a splice in an optical fiber in the presence of noise generates a nulling filter from a segment of a signal received from the optical filter by determining a set of coefficients having an initial "1" followed by p-1 "0" values and w.sub.i finite impulse response filter values, where p is a prediction interval greater than the width of an expected splice signature. The received signal is processed by the nulling filter to remove exponentials from the received signal, leaving an error signal containing noise and splice information. The resulting error signal is processed by a correlation filter to reduce the noise in the error signal. The output from the correlation filter results in a noise reduced error signal with the splice appearing as a noticeable dip in the waveform. The waveform is passed through a threshold detector to identify the splice when the dip exceeds a predetermined threshold.
