Description: Specifies the transmission format standard applied for the startup stream. The start transport stream carries a Network Information Table that the RCST uses for acquiring the forward link signaling. Supported values are: -1: unspecified (automatic format acquisition is assumed) 0: DVB-S (support of this value is mandatory if DVB-S support is claimed) 1: DVB-S2 with CCM (support of this value is mandatory if DVB-S2 CCM support is claimed) 2: DVB-S2 with VCM or ACM (support of this value is mandatory if DVB-S2 ACM support is claimed) This allows the RCST to discriminate between CCM and VCM/ACM when selecting the forward link. The support of automatic format selection is optional. One or several of the other format selections must be supported, according to the claimed SatLabs profile support.
