A networked personal video recording ('PVR') system couples a plurality of clients to one or more PVR media servers over a network. One or more PVR media servers include television tuners to tune television signals. A storage medium buffers the television signals to implement PVR functionality. For example, the PVR media server records television programs for clients. Clients are assigned to television tuners, and the clients display television programs received at the assigned tuner. The network transfers the buffered television signals to the clients.

Resource management for a networked personal video recording system

Networked personal video recording system

According to one embodiment, a method is described. The method includes receiving a request at a control module from a first remote device to access media data from a storage management module and determining that a first user is requesting access to the data based upon a first remote identification (ID). The method further includes opening a second stream between the playback module and the storage management module and receiving the data at the playback module.

Home media network

A user interface is implemented on a client device remote from a host device. The host device operates an application program that implements a user interface, such as an electronic programming guide or a guide for a personal video recorder, that permits a user to control at least one target device. The host device transfers to the client device an identification of at least one scene. In general, a scene defines an abstract layout for at least one screen display of the user interface. The client device generates at least one screen display for the scene based on its interpretation of the scene. The client device then displays the screen as an implementation of the user interface. Thereafter, a user initiates, using the client device, an operation to control the target device. In response, the target device performs the operation. The host device may also display information at a client device. For example, the host device may transmit information about a media currently playing at the client device.

Independent buffer positions for a networked personal video recording system

A user interface, operating on a display client, for an application program, operating on a remote computer, is implemented such that the division of functionality between the application program and the user interface does not require the application program to possess information regarding the display capabilities of the display client. The remote computer transfers, to the display computer, an identification of a scene for a user interface of the application program. The scene defines an abstract layout for a screen display of the user interface. The user interface receives input from a user (e.g., the user selects a menu item from the user interface). The input event is interpreted, and data is generated based on the interpretation of the input event. The display client interprets the scene, and the data, based on the display capabilities of the display client. Based on this interpretation, the display client generates a display scene and display data for the scene. The display data is rendered on an output device of the display client.
