Abstract: In accordance with an embodiment, a method includes: obtaining a change trend of an available channel capacity on a first channel, wherein the first channel is used to transmit video data; adjusting, based on the change trend of the available channel capacity, a quantity of layers during layered coding of at least one frame of data in the video data; performing layered coding on the at least one frame of data based on a quantity of layers obtained after adjustment; and outputting coded data obtained through layered coding.

Abstract: A method for parsing a question in a knowledge base includes: receiving a question entered by a user; performing phrase detection on the question to determine candidate phrases; mapping the candidate phrases to resource items in the knowledge base; further determining values of observed predicates and possible question parse spaces; performing uncertain inference on each proposition set in the possible question parse spaces according to the values of the observed predicates and values of hidden predicates, and calculating confidence; acquiring a combination of true propositions in a proposition set whose confidence satisfies a preset condition; generating a formal query statement according to the combination of true propositions.
