摘要:
A method and an apparatus for controlling a multipoint conference are disclosed. The method includes: determining resolution-layered coding parameters of each terminal, and sending them to their corresponding terminals; receiving the code streams sent by each terminal, selecting code streams to be displayed by each terminal among the received code streams according to the display requirements of each terminal, and transcoding or mapping the selected code streams to the code streams decodable by the terminal; and sending the code streams decodable by each terminal to their corresponding terminals. The embodiments of the present invention use an MCU to control the resolution-layered coding, and therefore, the system can include both the terminal supporting the layering protocol and the terminal supporting no layering protocol. In addition, the calculation is reduced, and the system efficiency is improved.

The present invention discloses a method for obtaining an attenuation factor. The method is adapted to process the synthesized signal in packet loss concealment, and includes: obtaining a change trend of a signal; obtaining an attenuation factor, according to the change trend of the signal. The present invention also discloses an apparatus for obtaining an attenuation factor. A self-adaptive attenuation factor is adjusted dynamically by using the latest change trend of a history signal by using the present invention. The smooth transition from the history data to the data last received is realized so that the attenuation speed is kept consistent between the compensated signal and the original signal as much as possible for adapting to the characteristic of various human voices.

A semiconductor structure which exhibits high device performance and improved short channel effects is provided. In particular, the present invention provides a metal oxide semiconductor field effect transistor (MOFET) that includes a low dopant concentration within an inversion layer of the structure; the inversion layer is an epitaxial semiconductor layer that is formed atop a portion of the semiconductor substrate. The inventive structure also includes a well region of a first conductivity type beneath the inversion layer, wherein the well region has a central portion and two horizontally abutting end portions. The central portion has a higher concentration of a first conductivity type dopant than the two horizontally abutting end portions. Such a well region may be referred to as a non-uniform super-steep retrograde well.

A hybrid search method may be used to identify information responsive to a query. A search may be performed utilizing a neighborhood graph and a partitioning tree. The partitioning tree may be searched to select one or more pivots that may be used to guide a subsequent search in the neighborhood graph. Once the search in the neighborhood graph is unable to identify nearest neighbors in closer proximity to the query, the search may be switched to the partitioning tree. The partitioning tree may then be searched to select pivots that may be used to guide subsequent searches in the neighborhood graph. The searches performed in the partitioning tree and/or the neighborhood graph may be conducted utilizing an iterative algorithm.
