Method and system for implementing interactive televisions through near field communication technologies

摘要

Interactive data, audio data, and video data are respectively encoded and packaged, and then an interactive television program is produced by multiplexing them. A receiving terminal receives the interactive television program and performs unpacking and decoding. The unpacked interactive data are transmitted by a near field communication module. An operating terminal receives the unpacked interactive data by a near field communication module thereof, parses out corresponding participatory information, and carries out the interaction with the content of the present television program.

1. A method for implementing interactive televisions through near field communication technologies, comprising:
A, encoding and packaging interactive data, audio data, and video data respectively to form a corresponding interactive data packetized elementary stream, audio packetized elementary stream, and video packetized elementary stream, producing an interactive television program by multiplexing the elementary streams, and transmitting the interactive television program via a digital television network, wherein the audio data and the video data are encoded by using a Motion Picture Experts Group 2 (MPEG-2) encoding scheme; B, receiving the interactive television program by a receiving terminal, unpacking the audio packetized elementary stream, the video packetized elementary stream, and the interactive data packetized elementary stream of the interactive television program during a first predetermined time according to a decoding timestamp information; and determining whether there is the interactive data packetized elementary stream in the interactive television program, if so, then controlling a near field communication module of the receiving terminal to enter a peer-to-peer mode for transmitting the interactive data during a second predetermined time according to a presentation time-stamp information; and C, receiving the unpacked interactive data by a near field communication module of an operating terminal, parsing out corresponding participatory information of the present television program from the interactive data by the near field communication module of the operating terminal, and carrying out a real-time interaction with content of the present television program based on the participatory information, wherein the step A comprises: A1, dividing a plurality of audio data, video data and interactive data in a television program into multiple groups of program data, each group of program data comprising an audio data, a video data of a frame, and an interactive data; A2, encoding and packaging the audio data, the video data and the interactive data of each group of program data, respectively, to form the corresponding audio packetized elementary stream, video packetized elementary stream, and interactive data packetized elementary stream; A3, multiplexing the audio packetized elementary stream, the video packetized elementary stream, and the interactive data packetized elementary stream into a single program transport stream, and then multiplexing a plurality of single program transport streams into a multiple program transport stream; and A4, scrambling and modulating the multiple program transport stream to form the interactive television program, and transmitting the interactive television program via the digital television network.
