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

Provided is a video on demand service providing device and method based on mixed multicast and unicast. A video-on-demand service providing device according to an embodiment of the present invention includes: a content synchronization unit that determines the transmission method based on the time difference between requesting corresponding content if the same video-on-demand content is requested from each terminal; and a content sending unit that determines the transmission method according to the content synchronization The transmission method determined in the unit sends the content to each terminal.

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...
