Abstract: A wireless video/audio data transmission system for adjusting Phase-Locked-Loop (PLL) parameters to synchronize the rate of clock reference transmission in a decoder module is provided. The decoder requires no external DDR memory for performing frame buffering, and instead, an on-chip internal SRAM memory is provided as the frame buffer. Frame images are processed under compressed domain at the decoder module using the SRAM. Synchronization of reference frequency in decoder with the reference frequency in encoder allows for the SRAM to be utilized. Timing information for synchronizing decoding of the video/audio data is defined by timestamps sent at set interval. PLL is used for adjusting frequency of the decoder or encoder module. The PLL is adjusted up when reference frequency of encoder module is higher than reference frequency of decoder module and the corresponding timestamp value at encoder module is lower in comparison to corresponding timestamp value, and vice versa.

Abstract: A predictive frame dropping method used in wireless video/audio data transmission using a video decoder or a video encoder under compressed domain instead of raw domain is provided. The method drops at least one consecutive P-frame directly in front of each I-frame sequentially in each group of pictures (GOP) for reducing the total amount of cache memory required for frame buffering and avoiding the memory from overflowing either before the data are being decompressed by the video decoder at the receiver side or after being compressed by the video encoder at the transmitter side. A controller for controlling the quantity of number of P-frames to be dropped is provided. The video decoder does not need any off-chip DDR memory. An SRAM can reside in either the video decoder or the video encoder for carrying out the predictive frame dropping method.

The device of the present invention comprises a platform having microchannels. The surfaces of the microchannels have surface energy gradient-inducing rare-to-dense microstructures.

When different microfluids flow through the microfluid bifurcation region, the microfluids will separate automatically to their own secondary microchannels according to the surface energy gradient. Thereby, droplets of different microfluids can be separated apart or split into diffluences.
