Method and apparatus for downloading content using channel bonding
View Patent ↗As additional channels are added to a communication system for applications, such as standard density (SD) and eventually high density (HD) Video on Demand (VOD), additional capacity can be realized by reducing the time required to transmit content. A reduction of transmission time (or an increase of the transmission rate) can be achieved by bonding chancels of the communication system. The bonded channels typically provide a statistical multiplexing gain because the additional bandwidth is treated as a large single channel for the download. Bonding channels of the communication system can provide high speed downloading of content, such as video content, far in excess of the playback rate. Using bonded channels can relax the Quality of Service (QoS) requirements of a data stream, such as a video stream, over an internet protocol (IP) network.
1. A method, comprising:
receiving a request to access an item of content using a communication system;
establishing a relationship between a first channel and a second channel; and
sending, at a faster rate than the item of content can be viewed on a user device of the communication system, a first portion of the item of content and a second portion of the item of content to a modem using the communication system via the first channel and the second channel, respectively, to enable, based on the faster rate, a trick mode for playback of the item of content.
2. The method of claim 1 , wherein the item of content comprises:
video on demand content.
3. The method of claim 1 , wherein the enabled trick mode is a skip ahead capability.
4. The method of claim 1 , wherein the item of content comprises:
a movie or a television show.
5. The method of claim 1 , wherein the sending comprises:
using a wireless link to send the first portion and the second portion.
6. The method of claim 1 , wherein the sending comprises:
sending the first portion and the second portion via the first and second channels concurrently.
7. The method of claim 1 , wherein the relationship between the first channel and the second channel comprises:
a bonded channel relationship.
8. The method of claim 1 , further comprising: sending an indicator that describes the relationship to the modem.
9. The method of claim 1 , wherein the sending comprises:
sending a first MPEG packet via the first channel and sending a second MPEG packet via the second channel.
10. An apparatus, comprising:
a transmitter configured to transmit a request to access an item of content using a communication system, the communication system being configured to provide the item of content according to a relationship between a first channel and a second channel; and
a receiver configured to receive, at a faster rate than the item of content can be viewed on a user device, a first portion of the item of content and a second portion of the item of content from the first and the second channel, respectively, to enable, based on the faster rate, a trick mode for playback of the received item of content.
11. The apparatus of claim 10 , wherein the first portion and the second portion comprise:
a portion of video on demand content.
12. The apparatus of claim 10 , wherein the trick mode is a skip ahead capability.
13. The apparatus of claim 10 , wherein the first portion and the second portion comprise:
a portion of a movie or a television show.
14. The apparatus of claim 10 , wherein the receiver is further configured to receive the first portion and the second portion concurrently.
15. The apparatus of claim 10 , wherein the relationship comprises:
a bonded channel relationship between the first channel and the second channel.
16. The apparatus of claim 15 , wherein the bonded channel relationship between the first and second channels is capable of being used by the apparatus.
17. The apparatus of claim 10 , wherein the first portion comprises: a first MPEG packet, and
wherein the second portion comprises: a second MPEG packet.
18. The apparatus of claim 10 , wherein the receiver is further configured to receive the first portion and the second portion using a wireless link.
19. A method, comprising:
receiving a request to access an item of content from a remote device;
establishing a relationship between a first channel and a second channel to the remote device;
accessing the item of content; and
transmitting a first portion of the item of content and a second portion of the item of content to the remote device via the first channel and the second channel, respectively, based on the relationship, to enable a trick mode for playback of the item of content.
20. The method of claim 19 , wherein the trick mode comprises:
a skip ahead capability.
