Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for performing incremental software installations. The system identifies a set of files associated with one or more software programs. Each file can be a component of a software program, or any file accessed by the software program or system when the software program is executed. The system receives a list of files associated with a software version that is not installed on the system. The system determines the differences between the set of files and the list of files, and receives a missing file from the list of files based on the differences. Finally, the system builds the software version on the system using the set of files and the missing file. In building the software version, the system does not assume a linear progression of updates and is able to reuse existing files to create nonlinear variations of software.

Abstract: Certain aspects of a method and system for automatically turning off motion compensation when motion vectors are inaccurate may include determining quality of a plurality of generated motion vectors. The interpolation of a plurality of output pictures may be controlled based on the determined quality. A plurality of original input pictures may be interpolated when the determined quality of the plurality of generated motion vectors is below a threshold value. A plurality of motion compensated pictures may be interpolated when the determined quality of the plurality of generated motion vectors is above a threshold value. A reduced interpolation mode may be utilized if a generated cut-off value is less than an entry threshold value and/or above an exit threshold value.

The system may be enabled to determine repeated pictures and scene changes. The motion compensation of output pictures may be stopped during detected scene changes.

Abstract: A method and system for placing advertising content in a three-dimensional virtual environment. A predefined space is selected for receiving the advertising content from an advertising provider. Information regarding the context of the space within the virtual environment is used by the advertising provider to select appropriate advertising content that relates to the context of the space within the virtual environment where the advertising content is to be placed. The advertising content can be content already existing on an advertisement server. The advertising content can change and alternate content can be substituted for the original content upon the occurrence of certain events.

Abstract: In a video system, a method and system for cross-chrominance removal using motion detection are provided. A luma motion detector in a motion adaptive deinterlacer may be used to determine a chroma current motion for a pixel in a video frame. The chroma current motion may be modified, based on a chroma motion mechanism comprising of an edge detection, a back-off, and a motion biasing, when the output pixel is found to be in a static chroma area of the video frame. A static chroma threshold parameter may be used to determine whether the output pixel is in a static chroma area. A cross-chroma reduction determined based on the current chroma motion, may be blended in the motion adaptive deinterlacer with a spatial average approximation of the output pixel to remove the cross-chrominance from the output chroma.

Abstract: System and methods for processing signals in a television system are disclosed and may include measuring relative power of RF carriers over a full bandwidth of one or more received TV channels. The method may also include determining based on the measured relative power, whether the one or more received TV channels includes a digital component or an analog component without demodulating the received TV channel. It may be determined whether the one or more received TV channels includes a digital component or an analog component without synchronizing and/or decoding the one or more received TV channels. The method may further include tuning to the one or more received TV channels. It may be determined whether an applied power gain for the one or more received TV channels is a maximum power gain.

Abstract: A method and system is provided, which may detect digital QAM, VSB and analog TV signals in a faster and more efficient manner than conventional systems. The system and method may be deployed in, for example, cable TV set-top boxes, cable TV modems and television set receivers, which may be coupled to a cable TV or off-the-air terrestrial network. Power measurements of the RF carriers found in a cable TV channel may be utilized to determine whether a digital QAM signal, digital VSB signal, or an analog signal is present in a TV channel. In this regard, it is not necessary for a receiver to demodulate, lock, synchronize, decode and/or validate any video or audio information or digital bit stream in order to detect digital QAM, digital VSB and analog TV signals, or not signal at all. Accordingly, the process of detecting digital QAM, digital VSB and analog TV signals is shortened and simplified.
