    • A frame synchronizer having broad applicability in television systems is particularly adapted for use in a chrominance time-compressed, luminance bandwidth reduced television system. The frame synchronizer, which separates the composite video signal into its component parts and thereby minimizes the dynamic range required to digitize the signal, demodulates the chrominance signal into its quadrature components and separates the luminance signal. The synchronization signal in the composite video signal generates slave distribution signals and slave horizontal and vertical addresses. The separated chrominance quadrature components and the luminance signal are digitized and, along with the slave distribution signals and the slave horizontal and vertical addresses, are temporarily stored in first-in, first-out memories which provide independent buffering and thereby accommodate a high degree of mismatch between master and slave timing. The chrominance and luminance data are accumulated in distribution registers and transferred to write registers which provide the data input to a frame buffer memory. Master distribution and master horizontal and vertical addresses are generated from a master synchronization signal along with write and read control signals. The data in the write register is read into the frame buffer memory at the slave horizontal and vertical addresses in response to the write control signal, and data in the frame buffer memory is read out from the master horizontal and vertical addresses in response to the read control signal, converted to analog signals, and combined to form a composite signal.
    • 在电视系统中具有广泛适用性的帧同步器特别适用于色度时间压缩,亮度带宽降低的电视系统。 帧同步器将复合视频信号分离成其组成部分,从而使信号数字化所需的动态范围最小化,将色度信号解调为其正交分量并分离亮度信号。 复合视频信号中的同步信号产生从属分配信号和从属水平和垂直地址。 分离的色度正交分量和亮度信号被数字化,并且与从属分布信号和从属水平和垂直地址一起临时存储在提供独立缓冲的先进先出存储器中,从而适应高度 主从时间不匹配。 色度和亮度数据被累积在分配寄存器中,并被传送到向RAM缓冲存储器提供数据输入的写入寄存器。 主分配和主水平和垂直地址由主同步信号以及写和读控制信号产生。 写入寄存器中的数据响应于写入控制信号被读入到从属水平和垂直地址的帧缓冲存储器中,并且响应读取从主水平和垂直地址读出帧缓冲存储器中的数据 控制信号,转换为模拟信号,并组合形成复合信号。

    • A method and apparatus for bandwidth compression allows two television programs to simultaneously occupy the bandwidth normally allowed for one television program. The composite video signals from first and second program sources are separated into chrominance, luminance and synchronization component signals for each. The chrominance signals for each program source are compressed in time, and the sync pulse from one of the program sources is used to generate a narrow sync pulse. The luminance signal from the one program source modulates a carrier signal, and the luminance signal from the other program source modulates a subcarrier signal. The compressed chrominance signals for the first and second program sources are transmitted, with the narrow sync pulse, for alternate lines of each image frame for each program, respectively, during the inactive video time, and the luminance signals for both program sources are transmitted during the active video time for each line of each image frame for each program, respectively. At the receiver, the compressed chrominance and the luminance signals for both program sources are detected, and the compressed chrominance and the luminance signals for one or the other of the two program sources are selected. The selected chrominance signal is stored during the inactive video time in an analog delay line, the output of which is combined with the selected luminance signal to reconstruct a composite video signal for the selected program source during the active video time in the selected program.

    • An apparatus for controlling distributed electrical loads including a microprocessor based central controller coupled via a twisted pair bidirectional data line to a plurality of microcomputer based transceiver decoders. Each transceiver decoder is coupled to a plurality of relays, each relay associated with a particular load to be controlled. Override switches and sensors, coupled to transceiver decoders provide override requests and information related to amibient conditions at the site of a load. A user defined data base includes sub-sets of relays called sectors, patterns of relay states, remote switches, a time dependent schedule and condition responses. A communication protocall and arbitration scheme provide for interactive communication between the central controller and each transceiver decoder with interfacing with the operation of any other transceiver decoder. Enhanced data storage capacity is achieved through dynamic allocation of memory space for pattern data. This divisional application is particularly directed to an improvement in the transceiver decoder permitting it to accumulate data from switch actuations and then transmit this accumulated data to the central controller whenever the transceiver decoder can gain access to the twisted pair data line.
