Embodiment Construction

[0016] Apart from the inventive concept, the elements shown in the drawings are well known and will not be described in detail. For example, a set-top box or digital television (DTV) and its components such as front end, Hilbert filter, carrier tracking loop, video processor, remote control, etc. Described in detail in this article. In addition, familiarity with networking and current and proposed recommendations for TV standards is assumed and not described herein, except for the concepts of the present invention. Such as for example NTSC (NationalTelevisionSystemsCommittee, National Television System Committee), PAL (PhaseAlternationLines, progressive phase inversion), SECAM (SEquentialCouleurAvecMemoire, sequential transmission and storage color television system), ATSC (AdvancedTelevisionSystemsCommittee, Advanced Television System Committee) (for example, ATSC standard: Program and System Information Protocol (PSIP, Program and System Information Protocol for Terrestrial...

Abstract

A time reference field is added to an L1 pre-signaling table of a broadcast DVB-T2 signal and location information is added to a Cell List Descriptor of a Network Information Table (NIT) of the broadcast DVB-T2 signal. A DVB-T2 receiver uses the time reference field and the location information from 5 the received broadcast DVB-T2 signal to determine its location.

[0001] Cross References to Related Applications [0002] This application claims Serial No. 61 / 869,148 filed August 23, 2013 (docket PU130123), filed August 23, 2013 (docket No. PU130128), filed September 26, 2013 Benefit of U.S. Provisional Application Nos. 61 / 882,827 (Docket No. PU130158) filed on October 16, 2013 (Docket No. PU130168) and 61 / 891,563 (Docket No. PU130168) filed on October 16, 2013. technical field [0003] The present invention relates generally to communication systems, and more particularly to television (TV) systems. Background technique [0004] Geolocation features can be used in several situations including targeted advertising, estimation of reception conditions at specific locations, and mobile navigation. Unfortunately, in current broadcast TV, a TV receiver (whether fixed or mobile) cannot determine its position from the received broadcast TV signal. One example of such a system is a Digital Video Broadcasting Terrestrial (DVB-T) type system su...
