Embodiment Construction

[0049] The general aspect of the invention is to use a different network than the one normally used for a particular application to receive bursty data. By utilizing reception of information transmitted in bursts over such an alternate network, the information can be used by the portable electronic communication device without waiting for reception of data bursts as is the case with conventional networks. By using this concept to change the DVB-H channel selection, the switching time can be greatly shortened.

[0050] When a user of a mobile phone, one example of a portable electronic communication device, changes channels from A to B, the mobile phone may not be able to utilize channel A because the mobile phone's receiver is turned off between receiving channel A bursts. B's data. Since channel B bursts are transmitted at intervals of about 3-4 seconds, the user's waiting time can be reduced if channel B data is made available to the mobile phone before the mobile phone rec...

Abstract

The present invention relates to connecting digital video data for presentation by a portable electronic communication device. A method comprises presenting (210) first digital video data as received using a first network, detecting (212) a selection of second digital video data to be presented by the portable electronic communication device, and presenting (216) the second digital video as received using a second network, so that a user of the portable electronic communication device quickly can be presented selected digital video data.

Description

technical field [0001] The present invention generally relates to the reception of media data, in particular a method and portable electronic communication device for receiving digital video data, and a computer program product for executing program steps according to the present invention. Background technique [0002] Handheld electronic devices, especially mobile phones, have added more and more functionality to provide different types of media content. In particular, video multimedia functions have been realized, for example, users can receive media content such as TV programs, that is, receive and display TV programs. [0003] Now, various mobile phone components that can provide the function of receiving TV programs have become a reality. [0004] One technique for delivering media to electronic devices is broadcast media, such as TV programs. Digital Video Broadcasting (DVB) is one such example, in particular DVB-Handheld (DVB-H) is a method of delivering digital me...
