The method includes the step of encoding the video signal data at a variable bit rate using at least one of a prioritized structure or a scalable coding structure to obtain a bitstream having a base layer and an enhancement layer. The encoding step encodes the video signal data such that a base layer bitrate is constrained to be less than or equal to a first value over a first time interval, and all of the bitstream, including the base layer and the enhancement layer, is constrained to a bitrate less than or equal to a second value over a second time interval."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for constrained variable bit rate (VBR) video encoding","description":"A method and apparatus are provided for encoding video signal data for transmission in a network.
