4.14.3 Broadcast Audio Stream with Multiple BISes - Source
Test Purpose:
Verify that a Broadcast Source IUT can stream multiple
BISes to a Broadcast Sink.
Test Case Configuration:
BAP/BSRC/STR/BV-18-C [BSRC, Multiple BISes, LC3 8_1]
BAP/BSRC/STR/BV-19-C [BSRC, Multiple BISes, LC3 8_2]
BAP/BSRC/STR/BV-20-C [BSRC, Multiple BISes, LC3 16_1]
BAP/BSRC/STR/BV-21-C [BSRC, Multiple BISes, LC3 16_2]
BAP/BSRC/STR/BV-22-C [BSRC, Multiple BISes, LC3 24_1]
BAP/BSRC/STR/BV-23-C [BSRC, Multiple BISes, LC3 24_2]
BAP/BSRC/STR/BV-24-C [BSRC, Multiple BISes, LC3 32_1]
BAP/BSRC/STR/BV-25-C [BSRC, Multiple BISes, LC3 32_2]
BAP/BSRC/STR/BV-26-C [BSRC, Multiple BISes, LC3 44.1_1]
BAP/BSRC/STR/BV-27-C [BSRC, Multiple BISes, LC3 44.1_2]
BAP/BSRC/STR/BV-28-C [BSRC, Multiple BISes, LC3 48_1]
BAP/BSRC/STR/BV-29-C [BSRC, Multiple BISes, LC3 48_2]
BAP/BSRC/STR/BV-30-C [BSRC, Multiple BISes, LC3 48_3]
BAP/BSRC/STR/BV-31-C [BSRC, Multiple BISes, LC3 48_4]
BAP/BSRC/STR/BV-32-C [BSRC, Multiple BISes, LC3 48_5]
BAP/BSRC/STR/BV-33-C [BSRC, Multiple BISes, LC3 48_6]
BAP/BSRC/STR/BV-34-C [BSRC, Multiple BISes, VS]
Pass verdict:
If the Codec ID is LC3, the IUT sends encoded LC3 audio
data in BIS Data PDUs on each synchronized BIS.
If the Codec ID is a vendor-specific Codec ID, the IUT
sends BIS Data PDUs on each synchronized BIS. The parameters
included in the Codec_Specific_Configuration data are as
defined in TSPX_VS_Codec_Specific_Configuration.
If the Codec ID is LC3, each parameter included in
Codec_Specific_Configuration data is formatted in an LTV
structure with the length, type, and value specified in
Table 4.83.
