    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 interface units connect to the internal network and prepare the information in the digital data stream for display, by a television, for example.

    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 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 clock recovery from an MPEG video data stream. To prevent jitter when the MPEG data 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 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 retransmission of other data over the network.
