Abstract

The embodiment of the invention discloses a video transmission method and system and optical network equipment, which are applied to the technical field of communications. The video transmission method provided by the embodiment of the invention comprises the following steps of: at the video receiving end, if a first video identifier contained in received first streaming media information and used for identifying first video information is two-layer or three-layer characteristic information of a passive optical network (PON), promoting video display, and sending the first video information toa video display device, such as a TV set or a display, of the receiving end to display. Thus, the video information of an opposite end can be received through the optical network equipment, the localend is promoted to display, so that even if user calling devices at both ends do not support video receiving and displaying, the video of the opposite end can also be displayed, and the realization requirement of video transmission is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a video transmission method, system and optical network equipment. Background technique [0002] As an indispensable communication tool in people's daily life and work, the telephone is widely used for its convenience and speed. With the vigorous development of optical access technology, the telephone passes through the Passive Optical Network (PON) system, Make a session connection with the peer phone. [0003] Among them, the PON system includes: optical line terminal equipment (optical line terminal, OLT), which provides a network side interface for the PON system, and connects to one or more optical distribution networks (optical distribution network, ODN); the ODN splits and transmits the downlink data of the OLT To each optical node (Optical Network Unit, ONU), or optical network terminal (Optical Network Terminal, ONT), and aggregate and transmit the upstream data ...
