    • A method and apparatus for distributing the data error correction and compression processing load between a modem (DCE) and a host data terminal equipment (DTE) enables modem implementation with minimal cost, power dissipation, and size. The DTE has a CPU and an associated memory. The memory contains a data transmission program for execution by the CPU to produce output data for transmitting, and at least a data compression algorithm and a data error checking algorithm for execution by the CPU under control of the data transmission program to asynchronously deliver data according to the data transmission program to a modem for synchronous transmission. The modem included in the DCE asynchronously received the data from the DTE and synchronously transmits it as output data. Due to the distribution of the data processing algorithms into the memory of the DTE, the DCE can be operated simultaneously in communication and control modes. Moreover, the modem can be controlled during data transmission or reception in response to a 〈DLE〉 code in combination with a predetermined control code.
    • 用于在调制解调器(DCE)和主机数据终端设备(DTE)之间分配数据纠错和压缩处理负载的方法和装置以最小的成本,功耗和尺寸实现调制解调器的实现。 DTE具有CPU和相关的内存。 存储器包含用于由CPU执行以产生用于发送的输出数据的数据传输程序,以及用于在数据传输程序的控制下由CPU执行的数据压缩算法和数据错误检查算法,以根据数据传输程序异步传送数据 数据传输程序到调制解调器进行同步传输。 包含在DCE中的调制解调器异步地从DTE接收数据,同步地将其作为输出数据发送。 由于数据处理算法分配到DTE的存储器中,DCE可以在通信和控制模式下同时工作。 此外,可以在数据发送或接收期间响应于&Lang&DLE&Rang&code与预定控制码的组合来调制调制解调器。

    • The disclosure describes a video player and display device for use in an aircraft entertainment system. The video display is incorporated into the face panel of the video player. The video output of the player is provided to its output terminals and to its face-panel monitor, thereby allowing a user to more easily utilize the video player's full functionality in the context of an aircraft IFE system. For example, if the video player is capable of performing automated timed play operations, the video player can more easily be programmed to start and/or stop at a particular time because programming of the player can be carried out in conjunction with the face-panel display screen. Also, it is easy to determine whether system malfunctions are in the video player by checking the monitor output. Where several video machines are concurrently playing different video choices, the flight attendant can easily confirm that the correct video is playing in the correct machine without having to actually go into the cabin and look at what is being displayed on the passenger terminal screens. The disclosed video player and monitor can also be provided with diagnostic circuitry that checks basic device parameters and/or operations, and displays the results of these checks on the display for easy viewing and consideration.
