    • 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.
    • 本发明涉及无线发送和接收具有第一多个块的类型的音频数字信号的方法,每个块具有第二多个帧,每个帧具有第三多个子帧,每个帧具有前导码 和二进制数据。 该方法通过搜索与作为块的第一帧的帧的第一子帧相关联的前同步码来有效地发送和重构数字音频信号,然后仅传输每个帧的二进制数据 在每个帧中,在每个块中。 在优选实施例中,用于传输数据的协议针对被发送的512个字节的每个数据分组进行呼叫。 发送器发送的数据包必须通过来自接收器的确认(ACK)包的传输来确认。 在这种情况下,未接收到数据分组和/或没有接收到ACK分组,并且传输必须重新开始,通过在块的第一帧的第一子帧的前导码之后立即重新发送数据分组来实现同步。

    • The present invention relates to a wireless data system which has a transmitter including a transmission buffer. The transmitter is configured to transmit a plurality of packets of encoded data, wherein a level of the transmission buffer is encoded in one of the packets of encoded data. The system further has a wireless receiver for receiving the plurality of packets. The receiver has at least one receiving component that receives the plurality of packets to generate a plurality of decoded signals, wherein the at least one receiving component is configured to receive one of the packets of encoded data from the transmitter to determine the level of transmission buffer. 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.
    • 本发明涉及一种具有发送器的无线数据系统,发送器包括发送缓冲器。 发送器被配置为发送多个编码数据分组,其中传输缓冲器的级别被编码在编码数据的分组之一中。 该系统还具有用于接收多个分组的无线接收机。 所述接收机具有接收所述多个分组以生成多个解码信号的至少一个接收组件,其中所述至少一个接收组件被配置为从所述发射机接收编码数据分组中的一个以确定所述发射缓冲器的电平 。 接收组件还被配置为存储在接收缓冲器中接收的多个分组,以确定接收缓冲器的电平,并且从发送缓冲器和接收缓冲器计算聚合缓冲器电平。 接收器控制来自接收缓冲器的分组输出速率,以将聚合缓冲器级别保持在期望的水平。
