    • In accordance with this invention, a system, method, and computer-readable medium that selectively scans files stored on a computing device for malware is provided. One or more files may be sent from a trusted source to a computing device that implements the present invention. The integrity of the files that originate from a trusted source is validated using a signature-based hashing function. Any modifications made to files stored on the computing device are tracked by a component of the operating system. In instances when the file is not modified after being validated, an aspect of the present invention prevents the file from being scanned for malware when a scanning event is directed to the file. As a result, the performance of the computing device is improved as static files from trusted sources are not repeatedly scanned for malware.
    • 根据本发明,提供了选择扫描存储在计算设备上的用于恶意软件的文件的系统,方法和计算机可读介质。 一个或多个文件可以从可信源发送到实现本发明的计算设备。 源自可信源的文件的完整性使用基于签名的散列函数进行验证。 对存储在计算设备上的文件的任何修改由操作系统的组件跟踪。 在文件在被验证之后未被修改的情况下,本发明的一个方面防止当扫描事件被引导到该文件时该文件被扫描恶意软件。 因此,由于来自可信源的静态文件不会重复扫描恶意软件,因此计算设备的性能得到改善。

    • Mapping data packets of a first data stream into data fields of a second data stream at several transmitters is provided by generating a first data stream with first data packets containing data associated with stationary receivers and second data packets containing data associated with mobile receivers in a head-end, where second data packets at the start of a group of consecutively transmitted second data packets contain placeholders into which signaling information is filled. A first data stream is transmitted from the head-end to each transmitter. Each transmitter extracts signaling information from the second data packets indicating in which data slot and in which data sub-frame of a received data frame the second data packet is transferred. Each transmitter inserts synchronization data in a specific data packet in each data slot containing second data packets. The first and second data packets are mapped consecutively into the second data stream.
    • 通过产生具有第一数据分组的第一数据分组来提供第一数据流的数据分组到多个发射机的第二数据流的数据字段,第一数据分组包含与固定接收机相关联的数据和包含与头部中的移动接收机相关联的数据的第二数据分组 -end,其中在一组连续发送的第二数据分组的开始处的第二数据分组包含填充信令信息的占位符。 第一数据流从头端发送到每个发射机。 每个发射机从第二数据分组中提取信令信息,指示在哪个数据时隙中和在哪个数据子帧中接收数据帧的第二数据分组被传送。 每个发射机在包含第二数据分组的每个数据时隙中的特定数据分组中插入同步数据。 第一和第二数据包被连续地映射到第二数据流中。
