    • A system and method for determining if DOCSIS-enabled devices connected to an HFC cable network are co-located. Subscriber account data is acquired to determine the DEDs associated with a subscriber account. The MAC address of a DED is used to obtain the MAC domain to which the DED is assigned and a ranging offset value associated with the DED. An alert is issued if multiple DEDs associated with a subscriber account are associated with different MAC domains. The alert signifies that DEDs associated with the account are not co-located. Where DEDs associated with an account are associated with the same MAC domain, the normalized ranging offset values associated with the subscriber's DEDs are compared to determine if the difference in any two ranging offset values exceeds a predetermined threshold. If the difference in any two ranging offset values exceeds a predetermined threshold, an alert is issued. The alert again signifies that DEDs associated with the account are not co-located.
    • 用于确定连接到HFC电缆网络的启用DOCSIS的设备是否位于同一位置的系统和方法。 获取用户帐户数据以确定与用户帐户相关联的DED。 DED的MAC地址用于获得分配了DED的MAC域和与DED相关联的测距偏移值。 如果与订户帐户相关联的多个DED与不同的MAC域相关联,则发出警报。 警报表示与帐户相关联的DED不在同一位置。 在与帐户相关联的DED与相同的MAC域相关联的情况下,比较与订户的DED相关联的归一化的测距偏移值,以确定任何两个测距偏移值中的差异是否超过预定阈值。 如果两个测距偏移值的差异超过预定阈值,则发出警报。 警报再次表示与帐户相关联的DED不是共同定位的。

    • A system and method for controlling a digital video recorder on a cable network. Signaling associated with the answering or initiation of a digital telephone call by a digital telephone subscriber is used to issue commands to a digital video recorder (DVR). A signal is generated by an MTA when the telephone is enters an “off-hook” state and sent to the DVR to initiate recording of a program being viewed by the called party. When the phone goes “on-hook”, the called party resumes watching the program from exactly where it was interrupted. The MTA may be connected directly to the VTD/DVR and the telephone state is determined by the DVR from information provided by the MTA. Alternatively, a soft switch monitors signaling from the MTA indicative of the state of the called telephone. A telephone state message comprising the telephone state information is then sent over an out-of-band channel/path to a DVR client within the VTD. The DVR client uses the telephone state information to control a DVR.
    • 一种用于控制有线网络上的数字录像机的系统和方法。 使用与数字电话用户应答或启动数字电话呼叫相关联的信令,向数字录像机(DVR)发出命令。 当电话进入“摘机”状态时,信号由MTA生成,并发送到DVR以开始对被叫方正在观看的节目的记录。 当手机“挂机”时,被叫方恢复正在中断的地方观看该节目。 MTA可以直接连接到VTD / DVR,并且电话状态由DVR从MTA提供的信息确定。 或者,软开关监视来自MTA的指示被叫电话的状态的信令。 包括电话状态信息的电话状态消息然后通过带外信道/路径发送到VTD内的DVR客户端。 DVR客户端使用电话状态信息来控制DVR。

    • A system and method for facilitating communication between a CMTS and a VoIP application server in a cable network. VoIP-enabled customer premises equipment (CPE) generates packets that are sent through a cable modem (CM) to a cable modem termination system (CMTS). A packet is parsed by CMTS and the destination IP address and port number compared to the destination IP address-port tuples received by the CMTS from a datastore. A packet that is directed to an IP address-port tuple on the target list (a “service request packet”) is modified to incorporate CMTS-identifying information and subscriber-identifying information in the packet header. When the VoIP application server communicates with the CMTS to reserve the network resources, the VoIP application server provides the CMTS with the CM MAC and CM IP addresses to facilitate resource allocation, subscriber identification and billing. This Abstract is not to be considered limiting, since other embodiments may deviate from the features described in this Abstract.
    • 一种用于促进有线网络中CMTS与VoIP应用服务器之间的通信的系统和方法。 启用VoIP的客户端设备(CPE)生成通过电缆调制解调器(CM)发送到电缆调制解调器终端系统(CMTS)的数据包。 与CMTS从数据存储区接收到的目标IP地址 - 端口元组相比,CMTS解析分组和目的IP地址和端口号。 针对目标列表上的IP地址端口元组(“服务请求包”)的分组被修改以将CMTS识别信息和用户识别信息合并到分组报头中。 当VoIP应用服务器与CMTS进行通信以预留网络资源时,VoIP应用服务器向CMTS提供CM MAC和CM IP地址,以方便资源分配,用户识别和计费。 本摘要不被认为是限制性的,因为其他实施例可能偏离本摘要中描述的特征。

    • In response to user requests for content, content may be dynamically mapped to communications channels, e.g., QAM channels, used to communicate multiple programs during the same transmission time slot, e.g., through the use of multiplexed MPEG streams. A customer premise device, e.g., STB, uses a tuner tuned to the QAM channel to receive the communicated stream, recovers multiple programs communicated using the single communications channel, and records and/or displays the recovered programs. In this manner, more programs can be received and recorded than there are tuners in the customer premise device, e.g., STB. In some embodiments a content service provider control node processes user requests for content, maps requested programs to transport streams, communicates mapping decision information to a content distribution node, and communicates QAM tuning information to the user devices which can then receive and record multiple programs communicated via a single communications channel.
    • 响应于用户对内容的请求,内容可以动态地映射到通信信道,例如QAM信道,用于在相同的传输时隙期间例如通过使用复用的MPEG流来传送多个节目。 客户驻地设备(例如STB)使用调谐到QAM信道的调谐器来接收所传送的流,恢复使用单个通信信道传送的多个节目,并且记录和/或显示所恢复的节目。 以这种方式,可以接收和记录比客户住宅设备(例如STB)中的调谐器更多的节目。 在一些实施例中,内容服务提供商控制节点处理内容的用户请求,将所请求的节目映射到传输流,将映射决定信息传送到内容分发节点,并将QAM调谐信息传送到用户设备,然后可以接收并记录多个节目传送 通过单个通信通道。

    • The detection of devices with duplicate media access controller (MAC) addresses in a cable network. A cable network device (CND) having a MAC address is connected by the cable network to a cable modem termination system (CMTS) having a gateway interface address. A centralized storage of historical cable modem MAC address/giaddr tuple data is used to identify CNDs that report duplicate MAC addresses. The cable network tracks the CND MAC address/giaddr tuple data of all CND requests that it receives and stores the MAC address/giaddr tuple data into a datastore (such as a database). When a CND seeks to access the network, the cable network looks into the datastore to determine whether the CND MAC address of the CND has previously been stored with a different associated giaddr, which would imply that there are multiple CNDs attached to different CMTSs where the CNDs share the same MAC address. If such duplication is detected, an appropriate remedial response is taken.
    • 在有线网络中检测具有重复介质访问控制器(MAC)地址的设备。 具有MAC地址的有线网络设备(CND)通过有线网络连接到具有网关接口地址的电缆调制解调器终端系统(CMTS)。 历史有线调制解调器MAC地址/ giaddr元组数据的集中存储用于标识报告重复MAC地址的CND。 有线网络跟踪其接收的所有CND请求的CND MAC地址/ giaddr元组数据,并将MAC地址/ giaddr元组数据存储到数据存储区(例如数据库)中。 当CND寻求访问网络时,有线网络查看数据存储区以确定CND的CND MAC地址是否先前已经与不同的相关联的giaddr一起存储,这意味着有多个CND附加到不同的CMTS,其中 CND共享相同的MAC地址。 如果检测到这种重复,则采取适当的补救措施。
