Parameter Description

assured
lowdelay
GET Space
Host: Space
GET /api/audio?assured=1&lowdelay=0 HTTP/1.1<CRLF>
Host: 138.198.34.250<CRLF><CRLF>
Parameter values are indicated using =. Do not insert space before and after =.
Example assured=1
Parameters are segmented using &. Do not insert space before and after &.
Example assured=1&lowdelay=0
There is no need to specify all parameters. Default values will be used for parameters that are not specified.
VN-E4 temporarily saves up to 2.5 seconds of the compressed data. Specify as assured=0 to request for the
latest data that is temporarily saved and assured=1 to request for the oldest data. Specify as assured=0 to
shorten the audio delay time. To enable stable playback in a network where jitter occurs, it is recommended
that this be specified as assured=1. Default value is 1.
Specifying as lowdelay=1 disables the Nagle algorithm of TCP, and audio delay time will be shortened. When
lowdelay=0 is specified, the Nagle algorithm is enabled and audio delay time will be prolonged. However,
transmission overhead will be enhanced. Default value is 1.
