- The present invention relates to a program or data reception on a broadcasting / multicasting network interconnecting mobile terminals sharing a bandwidth, and in the case of a telematics device for a vehicle, transmission of update data of more and more device models via this delta broadcasting technique And with the addition of low-cost, dedicated receiving end devices for broadcast / multicast networks to existing telematics systems or target systems, synchronized remote software and firmware upgrades are possible with a cost-effective delta data foundation .

③ Areas of future application

In the field of IoT, which mainly focuses on mobile telematics, home appliances, etc., it is necessary to synchronize remote update to the latest version of a large number of devices.

④ Most relevant prior art

Update data transmission system in unidirectional broadcasting network, satellite and DMB data broadcast network, IP based packet network based multicasting environment.

⑤ Problems of the prior art

One) In the well-known broadcasting network system such as DMB and satellite, existing update technology is inefficient in terms of data transmission time and speed in a finite communication channel as it transmits the entire update data.

2) In the service object receiving the data, that is, the data receiving terminal device, storage space and processing are required for the entire data of the related art. However, since the relatively small update data can be processed using the space through the present invention, The minimum requirement for updates is small.

(1) Specific means for solving the problems of the prior art (difference from the prior art)

One) The data to be updated is generated as a delta.

2) In the broadcasting stream allocation process, the data is composed and transmitted together with an update identifier for distinguishing the target model, the device and the software.

3) It becomes possible to broadcast update data for a plurality of apparatuses in the same stream space, rather than when assigning a conventional update data stream.

4) The receiving devices classify the update data corresponding to each model, the detailed device and the software as an identifier, and stores only the corresponding update data, and updates the data.

 A system and method for delivering delta update data in a broadcasting / multicasting environment in accordance with an embodiment of the present invention includes a one-way broadcast network, a satellite and a DMB data broadcast network, an update in an IP-based packet network- By streaming delta-based update data in a data transmission system, streaming update data for various models and software by utilizing bandwidth more effectively than transferring existing entire data streams.

One) It becomes possible to broadcast update data for a plurality of apparatuses in the same stream space, rather than when assigning a conventional update data stream.

2) The data receiving terminal device needs reception and storage space and data processing for the entire update data of the related art. However, through the present invention, reception and storage space use and processing for relatively small update data becomes possible.
