20100095328 | TECHNIQUE FOR CONTROLLING THE DOWNLOAD OF AN ELECTRONIC SERVICE GUIDE - A technique for controlling a download of an electronic service guide (ESG) for media content distribution services to a user device is proposed. First, a user behaviour related to the user device is monitored. Second, a ranking of fragments of the electronic service guide to be downloaded interactively onto the user device is determined, based on the monitoring. The download of one or more of the fragments to the user device is then initiated based on the ranking. This technique is particularly useful when a transmission capacity available for downloading fragments of the ESG is limited. | 04-15-2010 |
