Abstract: Time synchronization in a wireless communication system comprises transmitting a synchronization frame from a transmitter to a receiver over a wireless communication medium. The synchronization frame includes a timestamp indicating the transmitter local time when a symbol at a predefined position of the synchronization frame is placed on the wireless communication medium for transmission. The synchronization frame is received at the receiver which determines a receiving time comprising the receiver local time when said symbol of the synchronization frame was received at the physical layer of the receiver. Time synchronizing is performed by determining a difference between said timestamp and said receiving time, and adjusting the receiver local time based on said difference to time synchronize the receiver with the transmitter.

Abstract: Uncompressed video information is transmitted over a wireless communication medium from a wireless sender device to a wireless receiver device. Progressive transmission data rate adaptation is performed on original uncompressed video pixel information. The progressive transmission data rate adaptation is performed on selected pixel information to obtain a rate-reduced pixel information. The rate-reduced pixel information requires a lower transmission data rate than the original frame. The rate-reduced pixel information is transmitted over the wireless communication medium to the wireless receiver device. At the receiver, a reverse operation is performed to recover the original uncompressed video pixel information.
