Abstract
An apparatus for receiving essentially uncompressed HDTV video must generate an accurate pixel-rate clock to enable the reconstruction of a video frame. The clock pixel-rate generated must match a received video pixel-rate. In such system, signals for generation of horizontal and vertical synchronization are not transmitted over the wireless link to conserve the use of bandwidth. In the invention, a start of frame (SOF) indication is extracted by a symbol detection and synchronization (SDS) module and is used to generate the pixel-rate clock.
