Abstract

The invention discloses a system-on-chip (SoC) for realizing fusion of an optical network unit and a set-top box, and the system comprises a passive optical network media access control module for receiving a passive optical network (PON) data frame, converting the PON data frame into an Ethernet data frame and sending the Ethernet data frame to a packet processing module; a packet processing module which is used for carrying out routing processing on the received Ethernet data frame; a local message is sent to the application processing module according to identification information carried in the Ethernet data frame, wherein the local message comprises an optical network unit ONU service message or a set top box service message; and an application processing module which is used for carrying out corresponding processing according to the type of the local message. According to the technical scheme, the fusion of the functions of the optical network unit and the set top box can be realized by adopting a single system-on-chip, and the size, cost and power consumption of fusion equipment are reduced.

Description

technical field [0001] The invention relates to the technical field of optical network and set-top box, in particular to an on-chip system for realizing the integration of optical network unit and set-top box. Background technique [0002] ONU (Optical Network Unit, Optical Network Unit) is a terminal device responsible for optical fiber access in PON (Passive Optical Network, Passive Optical Network). The functions of the ONU device include an optical access function, a data forwarding function, and a service control function, etc., and are usually completed in an integrated system chip (SoC (System on Chip, system on chip)). [0003] STB (Set Top Box, Set Top Box) is a device that currently provides multimedia services in the form of IPTV (Internet Protocol Television, Internet Protocol Television) or OTT (Over The Top). The functions of the set-top box include audio and video decoding, audio and video output, application processing functions, etc., and are usually comple...
