Abstract

A wireless video/audio transmission system includes a transmitter configured to wirelessly transmit video/audio data streams The transmitter has an encoder module for generating the data streams including video data, audio data, and timing information. The video data includes only I-frames. The transmission system includes a receiver with a decoder module including a decoder IC, an SRAM, and a PLL circuit. The decoder IC detects the timing information, adjusts the PLL circuit to synchronize with a reference frequency, and decodes the data streams using the SRAM. Alternatively, the receiver includes a decoder module with a decoder IC and an SRAM. The decoder IC detects the timing information, generates a beacon pulse to be transmitted wirelessly to the encoder module, and the encoder module receives the beacon pulse, adjusts the PLL circuit incorporated within the encoder module accordingly so as to synchronize with the decoder module.
