Problems solved by technology

[0003] At present, VOD on the live network adopts the transmission method of live broadcast, and the transmission channel adopts the Gigabit / 100M bidirectional channel of PON technology, while the downlink bandwidth of the 10 Gigabit unidirectional broadcast channel is currently only used for broadcasting programs, and the actual bandwidth used is less than 3Gbps, the remaining 7Gbps bandwidth is idle, resulting in a waste of network resources

Embodiment Construction

[0024] In order to understand the above-mentioned purpose, features and advantages of the present invention more clearly, the technical solutions of the present invention will be described in further non-limiting detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] A kind of method that uses I-PON standard to realize that VOD plays and walks 10 Gigabit channel that the present embodiment provides, comprises the following steps:

[0026] 1) After the set-top box is turned on, it actively obtains the region information issued by the front-end system, and the region information includes region code and other information.

[0027] 2) The set-top box sends a request to the authentication server with the received area information and its own body information.

[0028] 3) If the front-end system confirms that the set-top box is an authorized set-top box, the authentication server allows the authentication and returns a request; if it is an una...

Abstract

The invention provides a method for realizing VOD playing through a 10-gigabit channel by using an I-PON standard, which comprises the following steps of: 1) after started, a set top box actively acquires region information issued by a front-end system, the region information comprising a region code; 2) the set top box carries the received area information and the carried body information to initiate a request to an authentication server; (3) if the front-end system confirms that the set top box is an authorized set top box, the authentication server allows the authentication to be passed and returns a request, and if the set top box is not authorized, the the authentication cannot be passed; and 4) after the authentication is passed, the set top box carries the region information and the body information to apply for an EPG list from a front-end EPG system. According to the method, the security and the reliability of video signals are guaranteed, the traffic of a VOD large video bandwidth can be efficiently utilized in a 10-gigabit channel, and a resource waste is avoided.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of digital TV network transmission, and in particular, relate to a method for implementing VOD playback through 10 Gigabit channels using the I-PON standard. Background technique [0002] Based on the characteristics of huge downlink traffic and very little uplink traffic of radio and television users, SARFT formulated the I-PON technical standard - "I-PON is a fiber-to-the-home technology solution based on 10G IP broadcast technology and PON technology. Its 10G IP broadcast technology applies 10 Gigabit Ethernet to one-way broadcast network, and the two-way interactive part adopts PON technology", that is, an asymmetric transmission network is established. The network has two mutually isolated transmission channels, one adopts 10 Gigabit IP broadcast One is a 10-gigabit unidirectional broadcast channel using PON technology, and one is a Gigabit / 100-megabit bidirectional channel using P...
