    Abstract: A home network architecture has an internal digital network interconnecting devices in the home. Entertainment services are introduced into the network through network interface units that are coupled to an external network and to the internal network. The network interface units are selectively directly connected by a direct circuit crossbar to set-top electronics so that video data, for example, may be directly provided from a network interface unit to the set-top electronics without jitter. A passive hub, which does not have packet routing capability, is then used to provide signal regeneration and re-transmission of other data over the network.

    Abstract translation: 家庭网络架构具有在家中互连设备的内部数字网络。 娱乐服务通过耦合到外部网络和内部网络的网络接口单元引入网络。 网络接口单元通过直接电路交叉开关选择性地直接连接到机顶电子设备，使得视频数据例如可以直接从网络接口单元提供到机顶电子设备而没有抖动。 然后，不具有分组路由能力的被动集线器用于通过网络提供其他数据的信号再生和重传。

    Abstract: A home network architecture has an internal digital network, e.g. Ethernet, interconnecting devices in the home. Entertainment services are introduced into the network through network interface units 32 that are coupled to an external network. The network units perform the necessary interfacing between the internal and external networks and perform MPEG clock recovery from an MPEG video data stream. To prevent jitter when the MPEG video data stream is transmitted over the internal network, the recovered MPEG clock is locked by the network interface unit to an internal network clock and then transmitted over the internal network. Set-top electronics 40 recover the MPEG clock using the internal network clock thus enabling the video data to be generated and displayed on a television 12, for example.

    Abstract: A home network architecture has an internal digital network interconnecting devices in the home. Entertainment services are introduced into the network through network interface units that are coupled to an external network and to the internal network. The network interface units perform the necessary interfacing between the external and internal networks and perform MPEG cloc k recovery from an MPEG video data stream. To prevent jitter when the MPEG dat a stream is transmitted over the internal network to set-top electronics, the recovered MPEG clock is locked by the network interface unit to the internal network clock and then transmitted over the internal network. The set-top electronics then recovers the MPEG clock from the locked MPEG clock transmitted over the internal network. The video data may then be generated using the recovered MPEG clock and displayed on a television, for example.

    Abstract: A home network has an internal digital network (e.g. Ethernet) interconnecting devices in the home. Entertainment services are introduced into the internal network though interface units 32 that are coupled to an external network. The interface units perform the necessary interfacing between the external and internal networks, and provide terminals 12, 14, 16, 18 and 20 with entertainment services. Set-top boxes/electronics 40 prepare the information in the digital data stream for display, for example, by a television. Two-way communication between a set-top box and an interface unit is controlled by a computer. The separation of the interface unit and the set-top electronics allows a single network interface unit to provide programming selectively to a multitude of set-top electronics and televisions within the home.

    Abstract: A home network architecture has an internal digital network interconnecting devices in the home. Entertainment services are introduced into the network through network interface units that are coupled to an external network and to the internal network. The network interface units perform the necessary interfacing between the external and internal networks, and make the entertainment services available to all terminals connected to the internal network. A plurality of set-top electronics that do not have network interfa ce units connect to the internal network and prepare the information in the digital data stream for display, by a television, for example.
