摘要： Details of media encoding and decoding devices which support generic homing sequences, and methods for operating such devices are disclosed. The use of generic homing sequences may permit an embodiment of the disclosed invention to support real-time, bit-exact testing of existing and future media encoding and decoding devices. An embodiment of the present invention may permit the initialization of encoding and decoding algorithms to a known state, enabling bit-exact testing of a large group of devices using these algorithms, including those whose specifications do not support such functionality. This capability may permit the full-speed, bit-exact, testing, of both locally and remotely situated media encoders and decoders.

摘要： Seamless wideband support is afforded by utilizing split-band data streams. For wideband signals, the 8kHz bandwidth is divided into a low band, with approximately 0-4kHz bandwidth, and a high band, with approximately 4-8kHz bandwidth. Narrowband functions and services operate on the low band, while wideband functions and services operate on both low and high bands.

摘要： Complementary band-splitter and band-combiner devices and methods of operation of both are disclosed. Embodiments of the invention may allow wideband and narrowband functions and services to operate seamlessly by band-splitting wideband data into low-band data and high-band data. Narrowband data may comprise only low-band data. Wideband services may operate on both low-band and high-band data, while narrowband services may operate only on low-band data. Another embodiment of the present invention may include machine-readable storage having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the foregoing.

摘要： One or more methods and systems of effectively transmitting voice and voice band data from one node to another are presented. In one embodiment, the system comprises an NTP time server generating absolute times to computing devices such as residential voice over internet protocol (VoIP) gateways. The NTP time server generates absolute times in response to NTP time requests made by one or more computing devices such as residential VoIP gateways. In one embodiment, the method comprises determining an adequate rate for requesting absolute times from an NTP server, making periodic requests to the NTP server, obtaining the absolute times from the NTP server, and generating an adjustment parameter for use by a computing device such as a residential VoIP gateway.

摘要： A system and a method for wireless playing media files utilizing a central server, in which a database of media files is stored, is described. The system includes a base-station connected to the server, a set of media clients that can be placed in different locations within the service area of the base-stations. The media clients can wirelessly connect to the server via the base-station to access the media files database and download media files, decode and play the media files. The media clients can be connected to devices capable of outputting the media files decoded and played by the media clients. The media clients can be also incorporated into mobile devices and cars, such that a user can download media files from the server and be able to display them at a location remote from the server and the service area of the base-station.
