Information processor
View Patent ↗The invention provides an efficient transfer of video/audio contents recorded by a server in advance for a user to view the contents with a mobile terminal, whereby the user is relieved of troublesome operations. The information processor includes two record means for recording coded video/audio data, the second record means controls already played back data having already been viewed by the user of the data transferred from the first record means, and when data is newly transferred from the first record means, the retransfer means is provided which erases only the already played back data, and transfers the data corresponding to a capacity evacuated by the erasing from the first record means.
1. A method of managing multimedia content on a mobile device, the method comprising:
generating a play list of multimedia content including one or more multimedia programs for download to the mobile device;
receiving the one or more multimedia programs from a multimedia source in accordance with the play list;
storing the one or more multimedia programs in a memory of the mobile device;
updating management information when the multimedia content is reproduced at the mobile device, said updating comprising recording a status of the one or more multimedia programs as fully or partially reproduced;
determining a size of data reproduced at the mobile device based on the management information;
preparing a transfer plan based on a coding system of the one or more multimedia programs, including determining reference points for the partially reproduced programs such that playback of the partially reproduced programs can proceed from the reference points and the reference points provide an overlap with a portion of the partially reproduced multimedia programs already reproduced at the mobile device; and
transferring additional multimedia content from the multimedia source to the mobile device in accordance with the transfer plan, wherein each fully reproduced multimedia program is erased and a portion of each partially reproduced program is erased up to its corresponding reference point, and wherein a size of the multimedia content transferred is determined based on the size of the data reproduced at the mobile device.
2. The method of claim 1 , wherein the multimedia content comprises MPEG-encoded video content.
3. The method of claim 1 , wherein the memory comprises a detachable integrated circuit and wherein transferring the additional multimedia content comprises mounting the integrated circuit to the multimedia source such that an electrical connection is formed between the integrated circuit and a controller of the multimedia source.
4. The method of claim 1 , further comprising displaying an indication of the fully reproduced and partially reproduced multimedia programs at the mobile device.
