The service uploading server (Catcher) is a package arrival notification and NVOD server upload (notification when sending a package from the delivery server, NVOD server registration of the transmitted package, MPEG file NVOD server upload, upload of the transfer schedule), the package of the platform List and status display, monitoring gateway server communication (displaying communication status with NVOD Gateway server), error monitoring (displaying for each error message, sending to error message CMS), watermark for news photos or news video content Or apply DRM to provide stability (encryption using the Video Encryption Algorithm).

The transaction server (Distribution Server) is updated with news content (text news, photos) to COD servers (VOD server and file server) distributed in a plurality of regional nodes registered in the media management system (MOC) 170. News, video news).

The transaction server (distribution server) manages state information on the VOD server for each local node, and adds or deletes a server to the VOD server management list according to the corresponding information when adding and deleting the VOD server.

In one embodiment, the plurality of COD servers (VOD server and file server) may be distributed and installed in a plurality of subscriber switch 220.

Data broadcasting data including the text news or photo news transmitted from the IPTV service system and PSI / SI information about the news channel are transmitted to a plurality of IP set-top boxes joined to a multicast group of the premium network 200. It is sent using the IP multicast protocol (eg PIM-SM).

The IP multicast routing protocol used in the L3 switch of the premium network 200 includes Distance Vector Multicast Routing Protocol (DVMRP), Multicast Extensions to OSPF (MOSPF), Core Based Tree (CBT), and Protocol Independent Multicast- (PIM-SM). The multicast routing protocol of any one of Sparse Mode) and Protocol Independent Multicast-Dense Mode (PIM-DM) may be used.

Each router including rendezvous point (RP) of IPTV backbone network / access network / subscriber network, metro switch (L3 switch), N-Topia switch (L3 switch) (N-Topia: LAN equipment installed in a group building where UTP is installed Layer 3 network equipment including a service using a high speed Internet) and a subscriber switch (L3 switch) 220 each use a PIM-SM multicast routing protocol. The subscriber station (IP STB) and the subscriber concentrator 230 use IGMP and IGMP Snooping protocols, respectively.

The Internet Group Management Protocol (IGMP) is used between an IP set-top box terminal requesting broadcast channel selection / release and a Layer 3 network device (eg, subscriber switch 220) that accepts the request.

The IGMP Snooping protocol is a Layer 2 device (eg subscriber aggregation) located between an IP set-top box 310 terminal of a subscriber requesting channel selection / release and a Layer 3 network device (eg subscriber switch 220) accepting the request. Protocol running on device 230. The Layer 2 device (subscriber concentrator 230) running the IGMP snooping protocol recognizes the IGMP transmission / reception message between the IP STB terminal and the Layer 3 network device, and transmits channel information only to the IP set-top box 310 of the subscriber who made the channel request. send.

The subscriber IP set-top box 310 is a data broadcasting data including the text news or photo news from the subscriber switch 220 providing a plurality of broadcast channels (eg, 100) according to an IGMP-joined multicast group, and PSI / SI information and EPG information about the news channel are received by multicasting.

The Rendezvous Point (RP) of the premium network 200 has a PIM Join list and a PIM for each multicast group (broadcast channel) (for example, 100) since the broadcast channel is a multicast group. Manage the Prune list.

3B is a diagram illustrating static join to reduce channel zapping time of an IPTV in a subscriber IP set-top box.

The static join method used to reduce the zapping time of the broadcast channel in the subscriber's IP set-top box 310 is as if the subscriber's IP set-top box 310 is joined to all groups (channels) in router 3 (subscriber switch 220). In the same way, Join is requested to the upper L3 network equipment (Router 3, 2, 1) (Subscriber Switch, Ntopia Switch, Metro Switch, Rendezvous Point (RP)). As a result, the subscriber switch (router 3) 220 downloads the traffic of all broadcast channels (eg, 100 channels), and the subscriber switch (router 3) 220 receives all the groups (all broadcast channels). In order to keep up, it periodically sends Join messages to higher L3 network devices (Ntopia Switch, Metro Switch, Rendezvous View). The cycle occurs within 128 seconds of the end of the group joining time to maintain the group (broadcast channel) continuously.

The subscriber's IP set-top box 310 is a subscriber switch that zaps about 100 broadcast channels in such a way that the router (L3 network equipment) always joins the group (channel) regardless of the actual group (channel) JOIN. Router 3) 220 always receives the desired broadcast channel.

In addition, if the subscriber set-top box (STB) leaves group 1 (changes to another broadcast channel), the rendezvous point (RP) and the router may transmit an IGMP Group Leave message for leaving the group 1 from the IP set-top box (STB). 1,2,3 (Metro Switch, Ntopia Switch, Subscriber Switch) always maintain Join in all multicast groups (all broadcast channels) regardless of the IGMP Leave message of the subscriber set top box (STB). Therefore, a large amount of channel traffic of all broadcast channels (eg, 100 channels) of the IPTV headend system reaches the subscriber switch (router 3) 220 stably.

Since the subscriber switch 220 has downloaded the traffic of all broadcast channels, it reduces the broadcast channel zapping time, and the text news of the corresponding broadcast channel according to the IGMP Join message requested from the IP set-top box 310 of the plurality of subscribers. Data broadcasting data including photo news and PSI / SI information including the news channel are transmitted to the IP set-top box 310 of the subscriber.

The IP set-top boxes 310 of the plurality of subscribers access the subscriber switch 220 according to an IGMP Join / Leave message to select / release an IPTV news service broadcast channel.

The subscriber's IP set-top box 310 transmits an IGMP Join message to the subscriber switch 220 when the subscriber selects and changes the broadcast channel, and when the subscriber stops watching or when the subscriber changes the broadcast channel, An IGMP Leave message for the broadcast channel being watched is transmitted to the subscriber switch 220.
