FRAME ELEMENT LENGTH TRANSMISSION IN AUDIO CODING Russian patent published in 2015 - IPC G10L19/00 H03M7/30 

FIELD: physics, acoustics.

SUBSTANCE: invention relates to audio signal coding, particularly to frame element length transmission. Frame elements to be made available for skipping may be transmitted more efficiently by arranging such that default payload length information is transmitted separately within a configuration block, with the length information within the frame elements, in turn, being divided into a default payload length flag followed, if the default payload length flag is not set, by a payload length value explicitly coding the payload length of the respective frame element. However, if the default payload length flag is set, explicit transmission of the payload length may be avoided. Instead, any frame element, the default extension payload length flag of which is set, has the default payload length and any frame element, the default extension payload length flag of which is not set, has a payload length corresponding to the payload length value.

EFFECT: high accuracy of audio signal coding.
