6.1.3In-Band Service/System Information6.1.3.1In-Band PSIP TestsThe tests in this section verify the ability of the DUT to navigate using in-band service information data. In-band Emergency Alerts are also tested here. Table 6.1-5 describes digital services carried on three Transport Streams, modulated on RF channels 79, 80, and 81 on one of CableLabs Head-Ends. Each of the three multiplexes has been formed by play out of a 30 second or one minute loop, therefore system time given in the STT will be discontinuous, and reflect an incorrect time of day (approximately 12:05 pm, June 1, 2004 UTC). Services in the multiplex on channel 79 are described by a TVCT (file name RF79n.mpg). Services in channel 80 are described by a CVCT and include some two-part and some one-part channel numbers (file name RF80w2.mpg). Services on channel 81 are described by both TVCT and a CVCT, each of which assign different channel numbers to a given service (file name RF81v2.mpg). The DUT must disregard the TVCT if a CVCT is present in the Transport Stream. Table 6.1-5 identifies the one- or two-part channel number that should be displayed to the user for each service on these three multiplexes. Two virtual channels are hidden, thus not visible until such time as they might be selected by reception of a Cable Emergency Alert Message. The table also identifies the short channel name and the extended channel name, which has been chosen to identify the content. Note that channel 93-4 is interrupted once per loop (60 seconds) by an Emergency Alert event. EAS is tested in the following section. Here is a brief description of each of the virtual channels. Each is a 30-second or one-minute loop: The Science channel, (parental rating TV-14). Includes a Service Location Descriptor, a “GA94” MPEG-2 Registration Description, an AC-3 audio descriptor. A golf match, containing one English and one Spanish audio track. Rating is TV-PG-L. A data-only channel (one without a video or audio program element). A Korean channel (KISB) containing a single audio track labeled (by ISO 639 Language Descriptor) as Spanish. The program is rated TV-G and includes an “SCTE” MPEG-2 Registration Descriptor. A 30-second loop of the IFC channel. The program is rated TV-PG-DLSV, and includes two audio tracks. One is a Complete Main, and the other is”Music & Effects” channel. The M&E track is labeled with a Component Name Descriptor entitled “Crowd Noise.” Game Show channel, rated MPAA-PG13. Includes two English-language audio tracks, each labeled with a Component Name Descriptor. The first track is named “Home announcers” and the second is “Away announcers.” BBC America, including three audio tracks (no ISO-639 Language Descriptors). The audio tracks are of type Complete Main, Visually Impaired (VI), and Hearing Impaired (HI), as identified in accompanying Audio Stream (AC-3) Descriptors. This service is rated for the Canadian region (region_code 0x02) for the “Canadian French” dimension as “16+.” An HD channel (Hawaii volcanoes) with content advisory level TV-MA (for US region 0x01) and 16+ (Canadian region 0x02). An audio-only channel of classical music. Hidden channel (MTV Hits). The EAS message uses this as a Details channel. Hidden channel (a Prince movie). The EAS uses this as a Details channel, but at such a low priority that the DUT should not tune to it. A channel (Ovation) that will be interrupted by the EAS event occurring once per loop.

Table 6.1-6 – Descriptor List
Equipment: DUT, display monitor (if needed), 3 QAM modulators, RF combiner, 3 MPEG transport Stream Players, 3 transport stream files (“RF79n.mpg”, “RF80w2.mpg”, “RF81v2.mpg”) Setup: Connect the DUT to the combined RF output of the three QAM modulators (each fed by a stream player, set to RF channels 79, 80 and 81). The output power of the combiner needs to be set at 0 dBmv. Connect the output of the Combiner with the power level set to 0 dBmv to the DUT. Procedure:
