Circuits and methods for providing zero-gap playback of consecutive data streams in portable electronic devices, such as media players, are described. In some embodiments, a circuit includes a decoder circuit configured to receive encoded audio data and to output decoded audio data including data streams associated with a data file and a subsequent data file. Moreover, a predictive circuit, which is electrically coupled to the decoder circuit, is configured to selectively generate additional samples based on samples in the data file, where the additional samples correspond to times after the end of a data stream associated with the data file. Additionally, a filter circuit, which is electrically coupled to the decoder circuit and selectively electrically coupled to the predictive circuit, is configured to selectively combine or blend samples at a beginning of the subsequent data file with the additional samples. Note that the circuit may be included in an integrated circuit.

An apparatus and method is characterized by providing an optical transfer function between a predetermined illuminated surface pattern, such as a street light pattern, and a predetermined energy distribution pattern of a light source, such as that from an LED. A lens is formed having a shape defined by the optical transfer function. The optical transfer function is derived by generating an energy distribution pattern using the predetermined energy distribution pattern of the light source. Then the projection of the energy distribution pattern onto the illuminated surface is generated. The projection is then compared to the predetermined illuminated surface pattern to determine if it acceptably matches. The process continues reiteratively until an acceptable match is achieved. Alternatively, the lens shape is numerically or analytically determined by a functional relationship between the shape and the predetermined illuminated surface pattern and predetermined energy distribution pattern of a light source as inputs.

Electronically programmed signs consist of any array of picture elements (pixels) that can be controlled independently to create an image. Varying the intensity of each pixel and adding multiple colors per pixel will enhance the image quality. It is currently common to have displays that use one, two or three separate colors in a pixel (monochrome, red-green, and red, green and blue) with intensity levels of two, four, eight up to 256 and beyond. Multiple colored pixels can combine colors at various intensity levels to expand the displayable color palette. The number of colors it is possible to display is calculated by the following formula:total⁢⁢number⁢⁢of⁢⁢displayable⁢⁢colors=(number⁢⁢of⁢⁢primary⁢⁢colors)(number⁢⁢of⁢⁢intensitylevels⁢⁢per⁢⁢colors)While raising the number of intensity levels and colors improves image quality, it also raises the viewer's sensitivity to inconsistencies in both parameters.

Embodiments of a system that includes one or more integrated circuits are described. During operation, the system receives a sequence of video images, and calculates brightness metrics associated with the video images in the sequence of video images. Then, the system determines an intensity setting of a light source, which illuminates a display that is configured to display the sequence of video images, and scales brightness values of a given video image in the sequence of video images based on a given brightness metric associated with the given video image. Next, the system changes the intensity setting and scaling the brightness values when there is a discontinuity in the brightness metrics between two adjacent video images in the sequence of video images.

A signal processing apparatus includes a decoding unit, an analyzing unit, a synthesizing unit, and a selecting unit. The decoding unit decodes an input encoded audio signal and outputs a playback audio signal. When loss of the encoded audio signal occurs, the analyzing unit analyzes the playback audio signal output before the loss occurs and generates a linear predictive residual signal. The synthesizing unit synthesizes a synthesized audio signal on the basis of the linear predictive residual signal. The selecting unit selects one of the synthesized audio signal and the playback audio signal and outputs the selected audio signal as a continuous output audio signal.

Implants, and processes for installing them, which replace the medial condyle and portions of the patellofemoral channel but preferably not portions of the lateral condyle that articulate relative to the tibia. Processes are provided which allow proper location and orientation of an anterior resection and a distal resection on the femur, which make use of a transition point which can be designated on the bone, for navigating proper positioning of such implants. Proper positioning of the implant relative to the femur for insuring a smooth transition between lateral portions of the implant and the lateral condyle is thus reduced to determining proper medial / lateral location of the implant on the anterior and distal resections. Such implants and processes can allow, among other things, for controlled location and orientation of an implant on the bone which saves lateral compartment bone, which eliminates the need to sacrifice the anterior and posterior cruciate ligaments, and which is adapted for minimally invasive surgery with its attendant benefits.

A directional, wideband, planar antenna arrangement is a class of Vivaldi aerial constructed as a plurality of conductive layers disposed on at least one substrate layer. The conductive layers are arranged to form a flared notch, which widens from a closed end to an open end, and is arranged to conform to a hybrid curve. The hybrid curve comprises a plurality of self-similar curve sections, and, as the flare widens, each successive curve section is scaled up by a scaling factor and joined at its wider end with a neighboring curve section. The hybrid flared notch can also be implemented in antipodal and balanced antipodal Vivaldi aerials.

The invention discloses a live broadcast time shift method which is applied to a live broadcast network including a client and a server. The live broadcast time shift of a user on the client is divided into pause and play. The client acquires the time label of a first index file currently parsed by the client according to pause, and acquires the played time of a video clip corresponding to the first index file. The client determines the timestamp of pause in a live broadcast video according to the time label and the played time. When the client receives play, a live broadcast time shift request is sent to the server according to the time shift time and timestamp of play. The live broadcast video in the live broadcast network is parsed and played according to a second index file returned by the server. After a user who watches live broadcast carries out live broadcast time shift, discontinuous screen caused by play screen hysteresis and play delay is reduced, and the user experience is improved. The invention further discloses the client.

Embodiments of a system that includes one or more integrated circuits are described. During operation, the system receives a video image. Then, the system jointly modifies brightness values of pixels in at least a portion of the video image and an intensity setting of a light source to maintain light output from a display while reducing power consumption by the light source, where the light source is configured to illuminate the display that is configured to display video images. Next, the system adjusts color content in the video image to correct for a dependence of a spectrum of the light source on the intensity setting.
