Abstract: Interest in the information transmission capability of the segments of the television signal primarily intended for synchronization is not new to the television industry. As early as 1953 a technique was developed in Germany utilizing the vertical blanking interval of the television signal for the transmission of test signals.<sup>1</sup> By 1956 use of the vertical interval for test signal transmission was authorized, here in the United States and soon became widespread. The 98th Technical Conference of the SMPTE, held in Montreal, in November 1965, devoted a session to Television Transmission Testing which included three papers on the use of the vertical interval.<sup>2–4</sup> Subsequently, much imaginative use has been found in both the vertical and the horizontal blanking intervals for information not necessarily related to the accompanying program material. Inasmuch as several of the proposed usages are conflicting in their intended assignment of the available television lines, it was felt appropriate to review the situation at this time.
