    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 TV graphical user interface includes a graphical channel changer for enabling a user to select a required TV channel among about 1000 channels provided by a satellite TV system. The graphical channel changer contains a vertical channel bar composed of channel boxes that display numbers and logo s of selected TV channels. To switch the TV set to a required TV channel, the user directs the pointing device at the graphical channel box that indicates the required channel. A direct access channel bar is arranged on a screen so as to cause the channel boxes to display the number and logo of a selected T V channel when the user directs the pointing device at the point on the direct access bar that represents the selected channel. The direct access channel b ar is provided with an absolute cursor position indicator that indicates to the user the numbers of TV channels represented by various points on the direct access channel bar, when the user moves the pointing device over these point s. When TV channels in the channel changer are arranged in alphabetical order o f channel or program names, the absolute cursor position indicator indicates t he first letter in the name of a TV channel or program represented by a point o n the direct access bar, at which the pointing device is directed.

    Abstract: A TV graphical user interface (GUI) in a satellite TV system enables users to create customized lists of TV channels. Everyday, favorite and theme lists may be generated to respectively combine TV channels being watched regularly, favorite TV channels and channels relating to particular subjects. An oval list name object is arranged on a screen to indicate the name of the currently selected list of TV channels. The users may click on the list name object to make their selection among various TV channel lists available in the TV system. In a channel changer mode, the TV GUI displays a graphical channel changer composed of channel boxes that show numbers and logos of TV channels in the currently selected list. To switch the TV set to a required TV channel, the user clickss on the graphical channel box that indicates the required channe. In a program guide mode, a list of TV programs may be provided based on the channel changer. Vertical program bars that display TV programs are aligned with the channel boxes indicating TV channels that carry the corresponding TV programs. To identify various TV channel lists available in the TV system, the oval list name object, as well as the channel boxes and program bars, are displayed in a color that represents a selected TV channel list.

    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.
