    • The present invention relates to a color LCOS display chip and the drive and control method thereof. With new structure design and drive and control method, the video signal nonlinear correcting chip, display drive signal control chip and other high cost special chips which are used in conventional control and drive circuit are abandoned. Multiple systems are integrated in a single chip to save PCB required for combination of multi-system chips, which leads to a lower production cost. The weight and size of control and drive circuit are reduced due to fewer integrated circuit chips and save of PCB. Power consumption is reduced without nonlinear correcting chips and display drive signal control chips. With the finite state machine (FSM) Scheduler as the core of digital signal processing module, the voltage coding value could be adjusted as per nonlinear characteristics of different crystal materials so as to achieve an optimal nonlinear correcting performance, which enhances the universality of the chip.
    • 本发明涉及彩色LCOS显示芯片及其驱动和控制方法。 采用新的结构设计和驱动控制方式,放弃了用于传统控制和驱动电路的视频信号非线性校正芯片,显示驱动信号控制芯片等高成本专用芯片。 多个系统集成在单个芯片中,以节省多系统芯片组合所需的PCB,从而降低生产成本。 控制和驱动电路的重量和尺寸由于集成电路芯片的减少和PCB的节省而减少。 没有非线性校正芯片和显示驱动信号控制芯片,功耗降低。 以有限状态机(FSM)调度器为核心的数字信号处理模块,电压编码值可根据不同晶体材料的非线性特性进行调整,实现最优非线性校正性能,提高芯片的通用性 。

    • The present invention relates to a method of wirelessly transmitting and receiving audio digital signals of the type having a first plurality of blocks with each block having a second plurality of frames, with each frame having a third plurality of subframes, with each subframe having a preamble and a binary data. The method efficiently transmits and recomposes the digital audio signals by searching for the preamble associated with a subframe, which is the first subframe of a frame, with the frame being the first frame of a block, and then transmitting wirelessly only the binary data of each subframe, in each frame, in each block thereafter. In a preferred embodiment, the protocol for the transmission of data calls for each data packet that is transmitted to consist of 512 bytes. The data packet transmitted by the transmitter must be acknowledged by the transmission of an acknowledgement (ACK) packet from the receiver. In the event, the data packet is not received and/or the ACK packet is not received, and transmission must recommence, synchronization is accomplished by the retransmission of data packet immediately after the preamble of the first subframe of the first frame of a block.

The receiving component is further configured to store the plurality of packets received in a receive buffer, to determine the level of the receive buffer, and to calculate an aggregate buffer level from the transmission buffer and the receive buffer. The receiver controls a packet output rate from the receive buffer to maintain the aggregate buffer level at a desired level.
