Abstract

A communication system and a family of methods for remote access to personal television service are disclosed. According to this invention, a remote personal TV service center provides centralized program guide information. A user may access to the personal TV service center through a digital video recorder which is connected to the personal TV service center via telephone modem or a network server. A user may access to the personal TV service center through a remote computer terminal or a personal digital assistant which is connected to a computer network. The user selects program events and programs the digital video recorder by using a graphical user interface installed in the front panel of the digital video recorder in case of local programming, or using a similar GUI which is incorporated into the Web pages presented to remote users by a Web server in case of remote programming. The media stream stored in one digital video recorder may be transferred to another digital video recorder. For data security protection during data transfer, all communication are authenticated and encrypted.
