“…It is worth noting that such a TV transmitter and its application to wireless video streaming appeared in an old article from the 1950s [9], in which a portable TV transmitter was developed and used as a military reconnaissance device. More recently, after the TVWS was officially approved, TVWS video streaming devices were also reported [10,11] but lacked certain design and implementation details.…”

This paper presents a television (TV) transmitter for wireless video streaming applications in TV white space band. The TV transmitter is composed of a digital TV (DTV) signal generator and a UHF-band RF transmitter. Compared to a conventional high-IF heterodyne structure, the RF transmitter employs a zero-IF quadrature direct up-conversion architecture to minimize hardware overhead and complexity. The RF transmitter features I/Q mismatch compensation circuitry using 12-bit digital-to-analog converters to significantly improve LO and image suppressions. The DTV signal generator produces an 8-vestigial sideband (VSB) modulated digital baseband signal fully compliant with the Advanced Television System Committee (ATSC) DTV signal specifications. By employing the proposed TV transmitter and a commercial TV receiver, over-the-air, real-time, high-definition video streaming has been successfully demonstrated across all UHF-band TV channels between 14 and 69. This work shows that a portable hand-held TV transmitter can be a useful TVband device for wireless video streaming application in TV white space.
