发明名称 Providing simulated broadcast services over a limited bandwidth channel
摘要 <p>A system and method is provided for simulating broadcast services over a cable television system by transmitting one or more programs, such as video, to a user in response to the user requesting the programs. A physical-layer channel is dynamically allocated to the user and each requested program is transmitted to the user on the allocated physical-layer channel. Therefore, channel selection is performed at a primary hub, rather than at a user's premises. Additionally, user-profile information can be stored in a primary hub, and one or more programs related to the stored user-profile information are automatically transmitted to the user without necessarily requiring the user to request the programs. <IMAGE></p>
