Video on demand methods and systems
View Patent ↗An entertainment head-end provides broadcast programming, video-on-demand services, and HTML-based interactive programming through a distribution network to client terminals in subscribers' homes. A number of different features are provided, including novel user interfaces, enhanced video-on-demand controls, a variety of interactive services (personalized news, jukebox, games, celebrity chat), and techniques that combine to provide user experiences evocative of conventional television.
1. A computer readable medium comprising executable instructions for performing a method comprising:
receiving a composite signal;
displaying a program received on the composite signal as it is received;
displaying a user interface to control the program display, the user interface comprising a delay control and a resume control;
receiving actuation of the delay control via the user interface, and in response to the delay control actuation,
persisting the user interface on screen with the resume control highlighted;
delaying display of the program;
displaying an indication of waiting email on screen; and
compressing and saving the program to a circular buffer as it is received; and
determining when a threshold time has passed since receiving actuation of the delay control; and in response to the threshold time passing, returning a transmission channel assigned to the program back to a pool of available transmission channels.
2. The computer readable medium of claim 1 further comprising executable instructions for decompressing and resuming display of the program as saved in the circular buffer from the time of delay actuation.
3. The computer readable medium of claim 1 wherein the program is chosen from among a list comprising video on demand and broadcast television.
4. The computer readable medium of claim 1 wherein the delay control and resume control are defined by HTML primitives.
5. The computer readable medium of claim 4 wherein displaying a user interface comprises rendering at least one HTML primitive.
6. The computer readable medium of claim 1 wherein the user interface is displayed on a WebTV terminal.
7. The computer readable medium of claim 1 wherein the user interface is displayed on a terminal and wherein the terminal comprises at least two interfaces.
8. The computer readable medium of claim 7 wherein the at least two interfaces comprise at least two of: an infrared interface, a user interface, a dial-up interface, and a cable interface.
9. The computer readable medium of claim 1 wherein the program received on the composite signal is a video program.
10. The computer readable medium of claim 1 wherein the program received on the composite signal comprises at least one interactive component.
11. The computer readable medium of claim 4 wherein at least one HTML primitive defines a hyperlink.
12. A system comprising:
means for receiving a composite signal;
means for displaying a program received on the composite signal as it is received;
means for displaying a user interface to control the program display, the user interface comprising a delay control and a resume control;
means for receiving actuation of the delay control via the user interface, and in response to the delay control actuation,
means for persisting the user interface on screen with the resume control highlighted;
means for delaying display of the program; and
means for compressing and saving the program to a circular buffer as it is received;
means for receiving actuation of the resume control via the user interface, and in response to the resume actuation;
means for decompressing and resuming display of the program as saved in the circular buffer from a time of delay actuation; and
means for determining when a threshold time has passed since receiving actuation of the delay control; and in response to the threshold time passing, means for returning a transmission channel assigned to the program back to a pool of available transmission channels.
13. A method comprising:
receiving a composite signal;
displaying a program received on the composite signal as it is received;
displaying a user interface to control the program display, the user interface comprising a delay control and a resume control;
receiving actuation of the delay control via the user interface, and in response to the delay control actuation,
persisting the user interface on screen with the resume control highlighted;
delaying display of the program; and
compressing and saving the program to a circular buffer as it is received;
returning a transmission channel assigned to the program to a transmission pool when a threshold time has passed since receiving actuation of delay control;
receiving actuation of the resume control via the user interface after the channel has been returned to the transmission pool, and in response to the resume actuation,
assigning a new transmission channel to the program, and
resuming display of the program saved in the circular buffer from a time of delay actuation by decompressing the program, and receiving remaining portion of the program on the new transmission channel.
