摘要： A cable modem system and architecture. A cable modem engine performs all cable modem functions, and a data networking engine performs all data and home networking functions. The cable modem engine is completely partitioned from the data networking engine. DOCSIS and VoIP functionality is implemented in the cable modem engine. The VoIP functionality may be in accordance with the PacketCable specification. The data networking functionality provided by the data networking engine may be in accordance with the CableHome specification.

摘要： A programmable channel scanning and acquisition method for a cable modem first performs a fast scan and then a slow scan to identify channels supporting cable modem services. The fast scan involves only a check of the cable modem AGC lock. A list of potentially operational channels is assembled and scanned. The list includes, in order of preference, the last known good channel, golden channels that are likely to support cable modem services, “learned” golden channels consisting of previous last known good channels, and other channels within the frequency plan range. The list omits channels on a “black list” known not to be operational and channels outside of the frequency range, except during registration. The method may be optimized by the setting of various parameters for operation in a DOCSIS or EuroDOCSIS environment.

摘要： A system distributes high-definition (HD) audio across a local telephone network. The system receives an audio selection from a communication device linked through the local telephone network. The audio selection may identify an audio source to retrieve audio data from, such as a broadcast channel, Internet streaming source, or others. The system can tune a communication resource to obtain an audio stream from the specified audio source, transcode the received audio stream into HD audio data, and distribute the HD audio data to the communication device via the local telephone network. The local telephone network may be an analog telephone network or an Internet Protocol (IP) network that supports Voice over IP (VoIP) communications.
摘要翻译：系统通过本地电话网络分配高清（HD）音频。系统从通过本地电话网络链接的通信设备接收音频选择。音频选择可以识别音频源以从诸如广播频道，因特网流媒体源或其他媒体之类的音频数据中检索音频数据。该系统可以调谐通信资源以从指定的音频源获得音频流，将所接收的音频流转码为HD音频数据，并通过本地电话网络将HD音频数据分发到通信设备。本地电话网络可以是支持IP语音（VoIP）通信的模拟电话网络或因特网协议（IP）网络。
