KR20050114169A - An individual multimedia contents saving technology & service of receiving a dmb broadcast at dmb terminal - Google Patents

Abstract

The present invention is a technology for storing multimedia content such as moving images and music of interest while receiving a broadcast program in a digital multimedia broadcasting (DMB) terminal. If you press the save button at any time while the unit content is being broadcast, when the user wants to save it, the entire contents are copied to the storage space in the terminal and compressed (MPEC, MP3, etc.) That's how. To this end, additional information (start tag, content information, finish tag, etc.) must be attached to the content transmission, and information such as the content title is stored together to increase convenience for later playback.

In order to be able to store and play individual content in this way, additional information (start tag, content information, finish tag, etc.) must be added during DMB broadcasting, so that additional revenue can be generated by storing individual content while providing it. Will be. This is the proposed service model.

Description

An individual multimedia contents saving technology & service of receiving a DMB broadcast at DMB terminal

Disclosure of the Invention An object of the present invention is to propose a technology and a service method for easily storing and playing broadcast multimedia content of a DMB channel in a DMB terminal.

The recording and recording of existing TV and radio broadcasting contents by individual content unit in the receiver requires human involvement, and the schedule information is also inaccurate, which causes difficulty in automatic recording / recording. In addition, the existing reception / recording / recording / reproducing equipment is a stand-alone device, which lacks a communication function, which makes it difficult to transfer and compatible stored information and to create a service model that must be followed by billing interlocking. In addition, the receiver is less mobile, and if there is mobility, the combination effect of the storage function is small, so there is almost no combo-type device in which this function is combined. In particular, it is impossible to record from the beginning of broadcast contents that passed due to the lack of caching function.

Recently, with the development of digital recording / recording technology, personal video recorder (PVR), which is a personal recording equipment combined with a TV receiver, has appeared, and a service model for recording with an EPG (Electrical Program Guide) has appeared. It does not automatically record and record content. In particular, as a service provided in the home, there is no mobile equipment yet, and there is no related service.

In the present invention, it is possible to attach digital additional information to broadcast contents in a DMB broadcasting environment, and to define a tag that can be distinguished and recognized for each content and broadcast contents according to the tag, thereby utilizing the content to be used by the DMB receiving terminal. It is a technology that allows automatic storage. This is different from the recording / recording method set in the past. At this time, when selecting to save in the middle of broadcasting while watching or listening to the contents of broadcasting contents to be stored, the temporary storage function (caching) can be utilized so that the entire individual contents including the previously broadcast part can be stored. have. Based on these functions, this storage device can also be linked to mobile phones, cameras, MP3 players, etc., coupled to DMB receiving terminals, to provide various and convenient services.

In FIG. 1, when multimedia content (video, music, etc.) is provided through a DMB channel (satellite, etc.), the DMB receiving terminal (mobile phone, etc.) always caches individual content with an identification tag (start, end, content information) attached thereto. If the receiver wants to permanently store the data in the storage device, copy it to the storage device in the DMB terminal and delete it immediately if not, and prepare to store the next individual content.

In FIG. 2, when the song provided with the identification tag as an individual content is provided as an internal configuration of the mobile phone combined with a DMB terminal / MP3 player, it is received and played through the speaker, and at the same time, the start tag is recognized and immediately stored in the cache memory. . If the DMB record button is pressed before the song ends, the file stored in the cache memory is immediately compressed and converted into an MP3 file and stored in the storage space of the MP3 player. At this time, attached digital information (song name, singer, genre, playing time, etc.) of individual contents is also stored and provided in the list of stored files in the MP3 player. Afterwards, the stored song is heard again through the MP3 player. When you press the DMB record button, you can link with your mobile phone so that you can pay for the content-based pay service model.

The greatest effect of the present invention is that the DMB broadcast receiver can automatically record / record multimedia contents such as moving images and music, which are desired in individual content units, instead of past time recording / recording. In particular, there is an advantage that can record / record the content while viewing or listening to the content, anyone can easily take advantage of this feature.

Through the present technology and service, a user can store desired broadcast content and use it at no additional cost anytime, anywhere, when he wants to see or hear it again or send it to whom. However, you can continue to use the content if you pay only once when recording / recording by content, such as downloading content from the wireless Internet. Based on the flat fee, the DMB subscription fee can be paid in bulk and used indefinitely.

DMB broadcasters (PPs) may have additional revenue models in addition to subscription fees for broadcast content, and DMB broadcast operators (SOs) will also generate revenue through DMB broadcast activation, and handset manufacturers will also increase sales.

Another service that utilizes this is service linked with EPG (Electrical Program Guide) for DMB. When EPG information is viewed through DMB linked wired and wireless Internet site and necessary program reservation recording is made, this reservation command is sent to the terminal through wireless Internet. When the program is broadcasted, the DMB terminal automatically operates and records the service.
