Description:
Channel results aggregated on the block of viewed channels.
NOTE: The frame count and error count statistics always have a value of zero if Environment was set to Real World Environment either in the IPTV Test dialog box (see Setting Up IPTV Test Parameters) or in the IPTV wizard (see Using the IPTV Wizard). These statistics cannot be obtained when a real video source is used in the test. For more information about latency calculations, see IPTV Test Diagram. For information about IPTV results displayed by Results Reporter, see IPTV Results in Results Reporter.
