A reference time distribution system and method use a data transmission network having a plurality of nodes to distribute the House Sync signal. A network-wide time signal is generated using a reference time generator, and the network-wide time signal is then distributed over the network to the plurality of nodes. At each node, the network-wide time signal is converted to a local synchronization signal for use in performing synchronization of the timing of each node. Either network-inherent timing and / or additional time signaling is used to provide the nodes attached to this network with a network-wide notion of time. The time information is converted locally into synchronization signals or time information as required by a respective application. When data is transported over the network, delay compensation is performed to simultaneously output different data streams that have been synchronously input into the network, regardless of the data path.

The present invention addresses the difficulties of controlling new devices which have been added to a network. A network protocol, the NetCTL protocol, enables a remote control device to dynamically learn the command codes of a newly network attached device if the new device is executing the protocol. The intervention of a system administrator is not necessary since the dynamic teaming process happens automatically when the new device is attached to the network. Because the protocol allows the remote control device to learn the codes dynamically, there is no need to consult previously written tables of commands which can omit the codes for newly invented devices. A user of the remote control device which has “learned” the codes (i.e. acquired the codes) for a network attached device is able to control that device, regardless of the device's physical location, by selecting and sending the network attached device a command code to perform an operation.

A video recording device includes the ability to record a video broadcast or video program while concurrently replaying a previously recorded video broadcast. This previously recorded video broadcast can be the same video broadcast that is recording or a different video broadcast. The record and playback operations are preferably triggered and controlled through a television on which the user can watch the playback of the recorded program. The viewer enters the data and commands for recording and playback preferably using a remote control device. Video programs are preferably recorded on a mass storage device. Preferably, the mass storage device is a hard disk drive coupled to the television through an IEEE 1394 serial bus network. Alternatively, any other appropriately configured memory device can be used to store the video programs. The television uses write commands to transmit to and record the program onto the mass storage device and read commands to retrieve previously recorded portions of a program to be replayed from the mass storage device. When playing back a previously recorded program or the recorded portions of a program which is still being recorded, the television will retrieve the packets of data from the mass storage device in sequence, using read commands to read from the appropriate locations where the appropriate packets have been stored. Each packet is then retrieved in sequence from the beginning of the program, even if the end portion of the program is still being recorded.
