    摘要： A word wise search is performed on an MPEG-2 stream. For every word, the invention finds word-aligned patterns of 0×00 0×00 or 0×00 0×01. The algorithm applied by the invention examines the input stream buffer for the first word aligned 0 in which further testing determines is the first byte of a valid start code, and sets the sub-buffer defined by the start of the search to the location of this discovered start-code as the zero-word reach. A second search is performed in the same part of the input stream buffer, this time looking for word aligned 1's (i.e. byte pattern 0×00 0×01). For each word aligned 1 that is a start code, an entry is made into a start code list. When all of these have been found, the offset of the start code ending the current zero-word reach is added to the list of start-code offsets. This process is repeated from the 0 word reach until the end of the buffer is encountered. If 0's are not word aligned, the start codes are found on the 1's search, otherwise the start codes are found on the first search.

    摘要： A method and arrangement for monitoring the audio portion of a broadcast signal includes a keyword listening device. A relatively limited set of keywords are stored in a memory and the keyword listening device monitors the broadcast signal for any of these keywords. Upon recognition of any one or more of the keywords, the broadcast audio signal is recorded for a period of time and then fully analyzed. After analysis, and in dependence upon the recorded and analyzed broadcast audio signal, a number of different functions, such as connection to an external network at a specified address, or control of a video cassette recorder, may be performed.

    摘要： A method and apparatus for testing a network bootable device provides a bootmode signature on the device to indicate whether a production test is to be performed. If a production test is to be performed, then test software is downloaded over a network from a server to device memory and then executed. If the test is successful, the bootmode signature is updated so that subsequent production tests are not performed. If the production test is not to be performed, then end user software is downloaded from the server to the device and executed.

    摘要： An apparatus and method for testing the installation and functioning of a component of computer system has a test engine which causes the identity of a test to be performed to be stored in a nonvolatile memory before being performed. The test is announced to the installer and then ran. This procedure is performed for a sequence of tests. In the event of a crash during testing, the step-by-step sequencing of the tests and the storage of the test identifies step-by-step in the nonvolatile memory simplifies identification of the test that caused the crash for the installer.

    摘要： A method and apparatus for optimal handling of high bandwidth streaming data in a computer system minimizes computational activities to achieve maximal performance. This performance improvement is accomplished by minimizing the amount of memory copying and also by minimizing the number of allocation and deallocations of objects which occur. Memory copying is a CPU/bandwidth intense operation when there is high speed streaming data on the input. The allocation and deallocation of objects is a system resource intense activity and requires a very significant amount of CPU processing per invocation in a computing device. Using a combination of techniques, the invention provides a technique that reduces both the number of memory copies as well as the number of objects which get allocated and deallocated during the course of operating on the streaming media data.
