Problems solved by technology

On the other hand, in the case of VOD service, since multimedia information is provided to each user by unicast, the number of users increases and the available wireless resources become scarce.
In particular, when there are many users requesting the same content, the same content is transmitted multiple times, which has an inherent disadvantage of increasing network traffic load.

Abstract

A VoD (Video on Demand) service providing apparatus based on mixed use of multicast and unicast, and a method thereof are provided. A VoD service providing apparatus in one embodiment of the present invention includes a content synchronization unit and a content transmission unit. In the content synchronization unit, if the same VoD content is requested from each terminal, then a transmission mode is decided according to a difference in time of requesting corresponding content. The content transmission unit transmits the content to each terminal according to the transmission mode decided in the content synchronization unit.

Description

technical field [0001] The present invention relates to the TV service technology using the Internet, more specifically, to the mobile Internet TV multicast transmission and its service technology. Background technique [0002] Recently, in accordance with 3GPP / LTE and IEEE802.16m standards, multicast broadcast services (multicast and broadcast services: hereinafter referred to as MBS)-based mobile IPTV service technology. In the mobile communication system, there is a disadvantage that it is difficult to provide high-quality services due to interference signals between base stations in the cell boundary area between base stations. Therefore, in order to provide mobile IPTV services, multiple base stations are combined to form a mobile broadcast area. to use. [0003] Mobile IPTV services are roughly classified into live TV services and video on demand (Video on Demand: hereinafter referred to as VOD) services. When providing live TV services, a mobile broadcasting networ...
