Abstract: The present application discloses a large-area dual-frequency heterojunction solar cell thin film deposition method and apparatus, where the large-area dual-frequency heterojunction solar cell thin film deposition method at least includes: placing a silicon wafer to be deposited in a process chamber of a flat-plate coupled chemical vapor deposition; introducing a process gas into the process chamber, the process gas including at least one of SiH4, H2, CO2, NO2, N2, O2, O3, Ar, and NH3; generating a plasma by exciting and dissociating of the process gas through a radio frequency power supply system fed into the process chamber; and transferring the plasma to the surface of the silicon wafer to be deposited under the electric field to form a silicon-based thin film or perform plasma interface treatment on the deposited silicon-based thin film.

Abstract: Disclosed herein are system, apparatus, method and/or computer program product embodiments for a multimedia environment that includes a computing device to display multiple multimedia segments within multiple display areas of a display device. The computing device may determine a first multimedia segment including a plurality of frames, and display the first multimedia segment within a first display area of the display device. The computing device may further determine, based on a user profile or content of the first multimedia segment, a second multimedia segment related to the first multimedia segment to be displayed within a second display area of the display device within the predetermined time interval.

Abstract: Disclosed herein are system, apparatus, method and/or computer program product embodiments for a multimedia environment that includes a computing device to display multiple multimedia segments within multiple display areas of a display device. The display device can include a first display area to display a first multimedia segment, and a second display area to display a second multimedia segment, which may be an advertisement related to the first multimedia segment. In some embodiments, to fit into the first display area, the first multimedia segment may be in a first format when received, and converted into a second format to fit into the first display area before being displayed in the first display area.

Abstract: Disclosed herein are system, apparatus, method and/or computer program product embodiments for a multimedia environment that includes a computing device to display a multimedia segment within a display area of a display device including multiple display areas. The computing device may determine a multimedia segment including a plurality of frames, and display the multimedia segment within a first display area of the display device. The display device includes the first display area and a second display area disjoint from the first display area, and each of the plurality of frames of the multimedia segment are displayed within the first display area. The multimedia segment can be in a first format, and the first display area and the second display area together has a capability to display the multimedia segment in a second format different from the first format.

Abstract: A computer-implemented method for creating in the encoded domain one or more video frames from a compressed still video image wherein image content in the created video frames is translated in location by panning or scrolling or a combination thereof on a non-block basis (i.e. pixel-level). A new block formed from portions of two other blocks is created by processing the original two blocks with identity matrices based upon the shift amount. By performing the creation process in the encoded domain processing power requirements are reduced and image quality is increased.

Abstract: A system and method for calculating data representative of at least one intermediary transition image between a first image and a second image in the encoded domain is disclosed. Cinematic transitions can be created between encoded still images and frames from video sequences. For each corresponding location within the first and second image, a transform coded value is calculated for the at least one intermediary image using the transform encoded data of the first and second images without transform decoding the transform encoded data. The transform coded values can be fully encoded using a compression protocol and transmitted to a device for decoding and display of the cinematic transition.

Abstract: A system and method is provided for variable bit rate encoding using a complexity ratio. Quantization parameter is calculated using a complexity ratio, which is equal to a local complexity divided by a global complexity. Complex pictures are allocated a larger bit budget relative to simple pictures. With the larger bit budget the quality of complex pictures can be maintained while reducing the overall size of the encoded video stream.
