Function Library

int GetAudioBitsPerSample (uint Number, out

uint Value)

VB.Net

SetAudioBitsPerSample (ByVal Number As UInte-

ger, ByVal Value As UInteger) As Integer

GetAudioBitsPerSample (ByVal Number As UInte-

ger, ByRef Value As UInteger) As Integer

Parameter(s)

Number

The number of the SDI channel, with allowed values from 0

to 31.

Value

Specifies the number of bits per sample, with the allowed

values:

16: 16 bits per sample

20: 24 bits per sample with 20 most significant bits valid

24: 24 bits per sample

Return Value

No error occurs if return value ≥ 0; if a negative value, please refer
to Other Functions for return code error information.

Audio Clock Phase Data Bypass

Sets or retrieves the bypass status of audio clock phase

data, with audio clock phase indicated by the number of video
clocks between the video sample and the audio sample, and,
at the receiver side, the audio clock generation extracts the
phase data and re-generates audio clock as the same phase
difference. If the incoming HD/3G SDI stream includes no
phase data or incorrect phase data, audio noise can result,
while SD SDI has no clock phase data, and thus is unaffected
by this setting.

Syntax

C/C++
