IntroductionIntroduction With the popularization of DSL access, fixed network operators urgently n

eed to develop multiple services and launch the Triple-play service. As part of the Triple-play service, IPTV has gradually become the major concern of the fixed network operators in the world.

In addition to traditional Live TV programs, IPTV can provide interactive video entertainment such as VOD, nPVR, Time-Shifted TV, providing users with better enjoyment. Moreover, IPTV can provide various broadband network based Value-Added-Services such as Internet access by TV, video telephony, game and home monitoring.

STBSTB

Currently, an IP STB usually supports the MPEG2 coding mode. With the launching of the new-generation video coding standard MPEG4 AVC/H.264, the new-generation H.264 STB has become matured gradually, and its solution will support Huawei’s new-generation IP STB EC628.The STB supports multiple access modes such as DHCP/PPPoE, and supports automatic remote upgrade, remote centralized management and troubleshooting. Cooperating with the Middleware and VOD server, the STB can provide various service functions.

Principle: As a multicast service control device, the DSLAM/L2 device replicates multicast packets to the user ports with multicast rights according to the user multicast rights delivered by the NMS.Advantage: Multicast packets are replicated at locations closest to users, so only a small amount of network bandwidth is occupied.Disadvantage: When controllable multicast is supported, L2 devices are required to support IGMP filtering, and there are high requirements for L2 devices.Applicable to: : 1) scenarios where there are a lot of users and channels2) new networks or large networks 3) late phase of IPTV service development on a large scale

2. The DSLAM processes IGMP packets and provides controllable multicast to finely control the rights of each user and each channel.

3. By adding EVM board, the MA5100 ATM DSLAM in the existing network is connected to the MAN/VDN to provide video service.

4. The IP DSLAM is directly connected to the MAN/VDN to provide video service, and provide Internet access and video service on the uplink at the same time, or it provides Internet access service and video service separately through multiple uplink FE/GE interfaces.

DSLAM working as a multicast control point: can prevent illegal users1. Prevent illegal sharing: finely control multicast rights of each port and each channel based on ports and

IP/MAC addresses.2. Prevent installation of extensions without permission: control the number of channels that can be

watched simultaneously based on ports and IP/MAC addresses.

39

QoS PolicyQoS PolicyTo raise the channel change speed, operators can directly push some channels to the DSLAM other than send them to the DSLAM according to user IGMP requests. In this mode, the DSLAM implements IGMP Station Join service, and sends IGMP Join packets upwards to join some multicast groups statically in advance, instead of joining the multicast groups dynamically according to IGMP requests of user terminals.

Besides, for networking in which multicast streams are directly pushed to the DSLAM, the DSLAM does not need to implement the IGMP Client function upwards, and can be used as the IGMP querier instead.

40

Live TV QOSLive TV QOS

Each DSL user has only one STB, and the DSLAM implements the IGMP Quick Leave service.

If there are multiple terminals in a family network and two terminals request the same channel, when one terminal changes the channel, the program stream of the other one will stop. This problem can be solved by implementation of IGMP Proxy through the xDSL MODEM/RG at the family network egress.

Due to the high bandwidth requirement of VOD service, the user bandwidth and

QOS parameter may need to be adjusted dynamically when a user requests the

VOD service. In this way, the user attributes on the BRAS can be dynamically

changed through the RADIUS COA, or adjusted by delivering policies to the
