Embodiment Construction

[0037] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] In the embodiment of the present invention, a message integration module is added on the side of the message platform. The message platform does not directly send the interactive TV message to the terminal, but publishes the interactive TV message to the message integration module, and injects the interactive TV message into the live code stream through the message integration module. Among them, following the requirements of MPEG-2TS (Transport Stream, TransportStream) flow, the packet identifier PID (Packet Identification) for transmitting interactive TV messages is added. After receiving the MPEG-2TS flow, the terminal detects the specific PID (PID is associated with the Table PAT (ProgramAssociation Table) described), and finally extract the interactive TV message. Interactive TV messages include but are not limited to the following key doma...

Abstract

The invention provides an interactive television message transmission device comprising a message integration module for receiving an interactive television message and multiplexing the interactive television message to a direct broadcast code stream for transmission. The invention further provides the interactive television message transmission device and a transmission method. The message integration module can insert in real time the interactive television message into the direct broadcast code stream after the interactive television message is published, thereby issuing the interactive television message together with the direct broadcast code stream, a terminal does not need to establish independent connection, and the time-sensitive interactive television message can be timely transmitted and received; the terminal treatment time difference is consistent with the video direct broadcast time difference; the interactive television message transmission device does not need to additionally increase resources of an interactive message transmission server which is interactive with the terminal; in channel switching process, the interactive television message transmission device does not need to independently establish and maintain an interactive television message signal channel, thereby protecting the channel switching experience.

Description

technical field [0001] The invention relates to the field of network communication, in particular to an interactive TV message transmission device, system and method. Background technique [0002] IPTV, or Internet TV, is a technology that utilizes broadband Internet infrastructure, uses home TV as the main terminal, and provides various digital media services including TV programs and value-added services through Internet protocols. Video / audio service is the basic service of IPTV, among which live TV and video on demand are the most basic. [0003] For live TV, in the existing broadcast TV system, service provision is one-way, and users can only passively accept the schedule of TV programs and enjoy specific services at designated times. The experience that live TV gives users is as irreversible as time itself. From the user's actual operation point of view, the live broadcast only supports simple operations such as entering playback, exiting playback, and switching chan...
