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 Electronic Program Guide (EPG). The video data may be converted from a 3D to a 2D format to be displayed with the EPG data. The video data may be converted from a 2D format to a 3D format, while the EPG data displays in a 2D format. The video data may be converted from one 3D format to another 3D format for display with the EPG data. The 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： Items are used to encode or in encoding a stereoscopic video signal. The signal includes first view frames based on a first view associated with a first eye perspective and second view frames based on a second view associated with a second eye perspective. The encoding includes receiving the stereoscopic video signal and determining the first view frames and the second view frames. The encoding also includes encoding the first view frames based on the first view and encoding the second view frames based on the second view and also the first view. In the encoding, a plurality of the encoded second view frames reference at least one first view frame for predictive coding information. Items are also used to decode the encoded stereoscopic video signal.

摘要： Preparing a three dimensional (3D) video graphical overlay based on a two dimensional (2D) graphical image in a decoded stereoscopic video signal. This includes receiving the 2D graphical image and receiving 3D information associated with the 3D video graphical overlay. This also includes reproducing, using a processor, the 2D graphical image to form a first view graphical image and a second view graphical image in a graphics window. This also includes mapping the first and second view graphical images, using the 3D information, to frames in the 3D video to form a 3D video graphical overlay of a 3D video stream. This also includes blending the 3D video graphical overlay and the 3D video stream.

摘要： In a method of encoding video content, bits of a first view and a second view of a three-dimensional (3D) video content are manipulated to occupy a first slice of video and a second slice of video, wherein a boundary is configured to be formed between the first and second slices. In addition, the bits of each of the first slice and the second slice are encoded separately from each other to form a first independently compressed video slice and a second independently compressed video slice. The first and second independently compressed video slices are then multiplexed to form at least one transport stream operable to be processed to render at least one of two-dimensional (2D) and 3D video.

摘要： A method and apparatus for managing bandwidth of video and data over DSL is disclosed. Incoming packets of data are first inspected to determine if the data is video data or other (non-video) data. The video data is further analyzed to determine if it is intended for real-time delivery to the subscriber or if the video data is intended for viewing at a later time by the subscriber. Video data intended for real-time delivery to the subscriber is re-compressed to optimize the video quality. Statistical multiplexing is performed on the video data for real-time delivery, the video data for viewing at a later time, and the non-video data. The bandwidth needs for the video data for real-time delivery, the video data for viewing at a later time, and the non-video data are all evaluated. Bandwidth is then allocated to the video data for real-time delivery, the video data for viewing at a later time, and the non-video data, based on the video data service quality requirements and latency sensitivity of the non-video data.

摘要： A wound closure system and methods utilizes a patient's own blood. The system preferably includes a chamber with a needle and a plunger for transferring and storing blood prior to surgery and the use of reversible anticoagulants. The chamber is pre-loaded with a reversible anticoagulant to prevent the blood from clotting during storage. When the surgery is complete, a counteracting agent is mixed with the withdrawn blood to counteract the reversible anticoagulant and allow the blood to clot. The clottable blood is then reintroduced into the patient to close a wound.

摘要： The present invention provides a method of using long digital filters in the presence of round-off errors by prescaling each filter coefficient by a scaling factor. The prescaled coefficients are used to weight input data samples. The resulting weighted data values are then divided by the appropriate scaling factor and combined to produce an output data sample.

摘要： Stored waveform records representative of respective repetitions of a repetitive signal are processed by reading a first waveform record from memory to form a reference signal. A second waveform record is read from memory to form a second signal, and the second signal is shifted in time in such a manner as to minimize the power of a difference signal, of which the instantaneous magnitude is representative of the difference in instantaneous magnitude between the reference signal and the time-shifted second signal. If the waveform records are identical but for jitter, and the power of the difference signal is brought to zero, this implies that the first waveform signal is synchronous with the processed second waveform signal, i.e., there is no jitter between the two signals. If waveform records resulting from the reference signal and the processed second signal are then averaged, the level of noise in the averaged record is reduced relative to the stored records and the averaged record is free of distortion due to jitter.

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.
