摘要： The system and method of the present invention provide a mechanism, for the purpose of efficiently interconnecting local area networks (LANs) across a frame relay network, by which LAN stations provide data flow control when the frame relay network becomes congested. The system of the invention comprises a Station Manager at the network end point internetworking unit (IWU) for managing the IWU, a LAN Manager for managing one or more LANs connected to the end point IWU, and Station Managers at each of the LAN stations managing the respective LAN station. In operation, the IWU receives from the frame relay network a congestion notification and the IWU Station Manager broadcasts this notification to its managed LAN station Station Managers. The LAN station Station Managers each examine the notification against its outstanding data to be transmitted and slows down data traffic that is destined for the congested portion of the frame relay network.

摘要： The system and method of the present invention provide a seamless approach for providing ATM connectivity for a Frame Relay DTE using an intelligent Terminal Adapter (TA). Using the system and method of the present invention, an enhanced Frame Relay protocol runs between the DTE and the ATM TA, the Frame Relay DTE is provided with not only the connectivity to the ATM network but also the full advantages of ATM transport mechanism. For instance, the FR DTE can choose to transmit its data using ATM Adaptation Layer (AAL) 1,3/4 or 5. Using the system and method of the present invention, a FR DTE may communicate with another FR DTE or to an ATM DTE through wide area or local area ATM network. The Frame Relay DTE can send data, image, voice, or video traffics across the ATM network via the FR/ATM terminal adapter.

摘要： A terminal adapter interfaces between a Data Terminating Equipment (DTE) and either a Frame Relay or a Switched Multimegabit Data Service (SMDS) telecommunications network so that the type of network over which the DTE is communicating is transparent to the DTE. The terminal adapter performs mapping from one protocol to another so that a native frame relay DTE can access an SMDS network and so that a native SMDS DTE can access a frame relay network. The address mapping method performed by the terminal adapter uses a parallel table look-up technique which reduces the chance of collision (when two or more addresses hash into the same table entry), eliminates the traditional comparison function to detect a collision, and eliminates the traditional pointer technique when a collision occurs.

摘要： The system and method of the present invention provide a seamless approach for providing ATM connectivity for a Frame Relay DTE using an intelligent Terminal Adapter (TA). Using the system and method of the present invention, an enhanced Frame Relay protocol runs between the DTE and the ATM TA, the Frame Relay DTE is provided with not only the connectivity to the ATM network but also the full advantages of ATM transport mechanism and, in particular, the connectivity through the ATM network using the SVC connection mechanism. Using the system and method of the present invention, a FR DTE may issue commands to the terminal adapter to set of calls, or connections, with other DTEs (FR or ATM). The terminal adapter then communicates with the ATM network and the destination DTE using the ANSI Q.2931 call establishment procedure (using commands such as Call.sub.-- Set-up, Call.sub.-- Accept, and Call.sub.-- Disconnect) to establish an SVC connection between the communicating DTEs. In addition, the FR DTE sends parameters such as quality of service (QOS), peak bandwidth, etc., so that the Frame Relay DTE can send real-time data, image, voice, or video traffics across the ATM network using the less expensive SVC mechanism.

摘要： A method and apparatus for content coding of Audio-Visual materials is presented. The content coding can then be decoded by a home station where the content coding is collected and processed. The content codes are utilized by the subscribers home station to collect information on the subscribers selection of AVM streams and record information on which AVMs have been presented to the subscriber. An audio-video material distribution system is described for supplying AVM streams to home station via a local distribution network. The home stations decode the content coding from the AVM streams and collect the encoded content codes. The collected content codes are then sent to collection centers for processing. The encoded information may also utilized to provide management of an upstream channel between the home stations and the video distribution node.

摘要： A method and apparatus for the automatic access control to multimedia presentations at the receiver in accordance with a viewer selected access mode and access classification data encoded into the multimedia presentation. Screening classification codes (SCCs) are embedded in the Audio Visual Material (AVM) delivered to a subscribers home station. The screening classification codes identify the type of content that follows in the AVM stream. For instance, violent content (video and/or audio) provided to a home station may contain a SCC that indicates violent scenes or violent action is forth coming in the AVM stream. The home station takes the SCC that are encoded and/or embedded in the AVM stream and applies a subscriber selected screening criteria. The screening criteria or suppression criteria are AVM manipulation commands. These AVM manipulation commands can blank the audio and/or video, cause the display of the last acceptable frame, perform obscuration transforms on the AVM stream or otherwise manipulate the audio and/or video portions of the AVM stream. The subscriber associates an AVM manipulation command with each of the available SCCs. The home station applies the subscriber desired manipulation commands to the AVM stream. Information on the subscriber selections are provided to an upstream node for subscriber behavior collection analysis.
摘要翻译：一种用于根据观众选择的接入模式和编码到多媒体呈现中的接入分类数据在接收机处对多媒体呈现进行自动访问控制的方法和装置。筛选分类代码（SCC）嵌入到传送到订户家庭的视听材料（AVM）中。筛选分类代码识别在AVM流中遵循的内容的类型。例如，向家庭站提供的暴力内容（视频和/或音频）可以包含指示暴力场景的SCC或AVM流中的暴力行为。家庭站采用编码和/或嵌入在AVM流中的SCC，并应用订户选择的筛选标准。筛选标准或抑制标准是AVM操纵命令。这些AVM操作命令可以使音频和/或视频消隐，导致最后可接受的帧的显示，对AVM流执行遮蔽变换或以其他方式操纵AVM流的音频和/或视频部分。订户将AVM操纵命令与每个可用的SCC相关联。家庭站将用户期望的操作命令应用于AVM流。关于订户选择的信息被提供给上游节点以进行用户行为收集分析。
