Digital Terrestrial Hdtv for North America: the Grand Alliance Hdtv System

The Grand Alliance HDTV System has been designed for the needs and requirements of North America. The system has a great deal of flexibility to facilitate interoperability and is heavily based on international standards. The Grand Alliance and the FCC Advisory Committee on Advanced Television Service have been working together to complete the design of the Grand Alliance HDTV System. When a tec...

Blind carrier phase synchronization for HDTV

Vestigial sideband modulation is the modulation scheme of choice for the American standard for high-definition television (HDTV). The symbol-error rate of this modulation format is highly dependent on the carrier phase estimation. Although a PLL tracks both carrier frequency as well as carrier phase in such a system, the residual phase noise needs further suppression. Phase synchronizers can ei...

Backward motion compensation for interlaced HDTV

The pel-recursive approach to motion estimation has been widely studied for compensating progressively scanned, moderate-resolution video. Although pel-recursive algorithms may not be suitable for application to interlaced high-definition television (HDTV), the underlying principle of backward motion compensation, upon which pel-recursive algorithms are based, can be exploited to improve existi...

CODER FOR AHYBRID HDTV TERRESTRIAL BROADCASTING SYSTEMSusie

A scalable source coder was designed for a hybrid HDTV terrestrial broadcasting system. The hybrid combination of analog and digital methods allows for both high video compression ratios and eecient utilization of the available channel capacity. EEcient channel utilization enables closer receivers to decode high quality video, and allows further receivers to decode natural looking, though lower...
