Abstract

Push printing from internet sources to a set top box through a cable head end connected to the set top box by a digital cable network. Push printing includes printing by unicast (point-to-point) printing from a remote internet source to a specifically designated printer connected to a specifically addressed set top box, multicast (one-to-many) printing from a single remote web source to multiple ones of printers connected to respective set top boxes, and one-to-group printing from a single remote web source to a group of set top boxes defined at the cable head end. Both unicast and multicast printing are accomplished from the remote internet site to a cable head end connected to the internet, with the cable head end transmitting the print job via a digital cable network to subscriber set top boxes. Notification of print status is provided from the set top box back to the cable head end, thereby allowing the cable head end to provide notification of successful printout back to the remote internet site.

Claims

1. A method for push printing of a print job from a remote internet site to a printer attached to a set top box, the set top box being connected via a digital cable network to a cable head end having internet access, said method comprising the steps of:

receiving the print job at the cable head end from the internet; and

transmitting the print job from the cable head end over the digital cable network to the set top box so as to print the print job from the set top box to the printer.

2. A method according to claim 1, wherein said print job includes destination information for the print job, and further comprising the step of identifying a set top box for transmittal in said transmitting step based on the destination information.

3. A method according to claim 2, wherein said step of transmitting includes the step of multicasting the print job to multiple different set top boxes from the cable head end.

4. A method according to claim 2, wherein said cable head end includes a preferences directory that defines groups of set top boxes, wherein said destination information designates one of said groups, and wherein said step of transmitting includes the step of multicasting the print job to the group.

12. An apparatus for push printing of a print job from a remote internet site to a printer attached to a set top box which, in turn, is connected via a digital cable network to a cable head end having internet access, comprising:

a program memory for storing process steps executable to perform a method according to any of claims 1 to 11; and

a processor for executing the process steps stored in said program memory.

13. Computer-executable process steps stored on a computer readable medium, said computer-executable process steps for push printing of a print job from a remote internet site to a printer attached to a set top box which, in turn, is connected via a digital cable network to a cable head end having internet access, said computer-executable process steps comprising process steps executable to perform a method according to any of claims 1 to 11.

14. A computer-readable medium which stores computer-executable process steps, the computer executable process steps for push printing of a print job from a remote internet site to a printer attached to a set top box which, in turn, is connected via a digital cable network to a cable head end having internet access, said computer-executable process steps executable to perform a method according to any of claims 1 to 11.

15. A method according to claim 1, wherein the cable head end determines whether or not to reject the print job.

17. A method according to claim 1, wherein the print job is printed out at the set-top box.

5. A method for push printing of a print job from a remote internet site to a printer attached to a set top box which, in turn, is connected via a digital cable network to a cable head end having internet access, said method comprising the steps of:

receiving the print job at the cable head end;

determining a destination set top box based on destination information in the print job;

constructing a logical printer corresponding to the printer connected to the destination set top box, the logical printer being created at the cable head end;

creating a confirmation server at the cable head end;

transmitting the print job from the logical printer over the digital cable network to the set top box; and

obtaining printer status via said confirmation server from a corresponding confirmation client created at the set top box.

6. A method according to claim 5, wherein destination information in the print job indicates multiple destinations, and wherein said step of creating a logical printer includes the step of creating multiple logical printers corresponding to each different printer type and configuration indicated by the destination address.

7. A method according to claim 6, wherein said step of transmitting includes the step of multicasting the print job to multiple different set top boxes from a single logical printer.

8. A method according to claim 5, further comprising the step of returning status information to the remote internet site based on the status information received from the confirmation server.

9. A method according to claim 5, further comprising the step of managing print queues based on printer status information obtained from said confirmation server.

10. A method according to claim 9, wherein said step of managing print queues includes the step of responding to user management of a print queue for a set top box, as reported to said cable head end via said confirmation server.

11. A method according to claim 10, wherein said step of responding includes the step of responding to a deletion of a print job by the user.

16. A method according to claim 5, wherein the cable head end determines whether or not to reject the print job.

18. A method for push printing of a print job from a remote internet site to a printer attached to a set top box, the set top box being connected via a digital network to a broadcasting station having internet access, said method comprising the steps of:

receiving the print job at the broadcasting station from the internet;

the broadcasting station selecting, based on the print job, a transmission mode for the print job, wherein the transmission mode is one of a unicast mode or a multicast mode; and

transmitting, in the selected transmission mode, the print job from the broadcasting station over the digital network to the set top box so as to print the print job at the printer.

19. A method according to claim 18, wherein, in the multicast mode, the broadcasting station simultaneously transmits the print job to multiple different set top boxes.

20. A method according to claim 18, wherein the print job is printed out at the set top box.
