Problems solved by technology

The fact that music files can be downloaded to a home computer at a lower cost and delivered to an MP3 player or mobile phone, and provide comparable or better quality, makes the multi-slot streaming alternative over GSM / EDGE much more efficient than what is on the market today. The other alternatives available are less attractive and not worth their price

Embodiment Construction

[0042] Briefly stated, the present invention provides a solution in which the resources available on a bandwidth-limited connection can be used more efficiently for the download of multimedia files. This is achieved by dividing the multimedia file into two parts which are transmitted in separate bit streams in an efficient manner.

[0043] The first low-quality part streamed by the bandwidth-limited access technology is delivered to the requesting user device, while the second high-quality part can be streamed at better timing and / or by providing better download conditions (such as better radio environment, Transmission quality or bandwidth) alternative access technology to send.

[0044] figure 2 Schematically illustrates one way of downloading a multimedia file using bitstream combination, ie via two different bitstreams, each carrying a portion of a selected multimedia file, according to an embodiment of the claimed invention.

[0045] In the figure, a user device 200 is...

Abstract

A method for downloading a multimedia file from a server (101, 201, 300, 701) to a user device (100, 200, 400, 700), at least partly via a bandwidth limited connection (202, 702), a server and a user device adapted therefore. A user device, connected to a server selects a multimedia file to be downloaded via two bit streams. In the server the selected multimedia file is divided and coded into a first, low-quality part, and into a second, high-quality part (503). When certain conditions (505) set up for the first part are fulfilled, this part is streamed via a first bit stream (506), and when certain conditions set up for the second part are fulfilled, the second part is downloaded via a second bit stream (508). In the user device, the first part is received and reproduced (603b) as a limited version, available to be played-up in real time (604), while the second part is reproduced and combined with the first part (610, in order to yield the original multimedia file.

Description

technical field [0001] The present invention generally relates to methods and apparatus for downloading multimedia files, and in particular for more efficient use of available resources when downloading multimedia files such as music files. Background technique [0002] Today, consumers have several options to choose from when purchasing multimedia content such as movies, games or music. The increased use of the Internet and mobile telephony and the development of services especially suited to the downloading and purchasing of different types of multimedia content, in addition to the traditional physical purchase of movies, software games and records, has made it easier to bring these types of products to market via public fixed and wireless networks . [0003] A powerful feature available today is the possibility for consumers to stream music in real time, ie to listen to the composition while it is being downloaded to the user's device. When streaming music, the required...
