ANNEX - GUIDELINES ON THE GENERATION OF REAL VIDEO MULTIPLE PLP TEST SIGNALS Summary The test signals are a subset of tests developed in the DVB-T2 V&V group to check corner cases of receiver buffer model operation and proper recognition of multiple PLP services in the received DVB-T2 RF signal by monitoring the displayed picture and sound of the TV product. It is expected that test equipment manufacturers will provide suitable test signals following the guidelines in this annex to enable receiver testing. A low bit rate transport stream >18 of 27

In addition TS1 (PRBS) is assigned to PLP1. A chapter is formed by repeating units a specific number of times. A new chapter containing new run lengths for TS0 and TS1 and a new number of unit repetitions is shown starting to the right of the red line.
