Embodiment Construction

[0037] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] Such as figure 1 As shown, it is a schematic diagram of the structure of the mobile multimedia broadcasting multiplexing subframe according to the embodiment of the present invention, and each multiplexing subframe includes a subframe header, a video segment, an audio segment and a data segment. The subframe header mainly describes the overhead information of the subframe, that is, the description of the video segment, audio segment and data segment in the subframe, including the description of the video segment encapsulating multiple video streams, and the audio segment encapsulating multiple audio streams. In each video stream and audio stream parameter set, a "program preview indication" field is provided to describe whether the video stream or audio stream is program preview information. Because a video s...

Abstract

The invention relates to a transmitting system of multimedia program preview information, which comprises a multiplexer, a modulator, transmitting equipment and a program preview generator, wherein the program preview generator is used for transmitting program preview information and a corresponding service serial number to the multiplexer; and the multiplexer is used for encapsulating video information of the program preview information in a video flow of a video band of a multiplexing subframe where the service serial number is positioned, adding program preview instruction information to aparameter set of the video flow, transmitting a multiplexing frame where the multiplexing subframe is positioned to the modulator and utilizing the transmitting equipment for transmission. A receivingterminal of the multimedia program preview information is used for receiving data of the multiplexing frame to demodulate and analyze the multiplexing subframe and analyzing the video program previewinformation from the video flow of the video band of the multiplexing subframe according to the program preview instruction information in the parameter set of the video flow of the multiplexing subframe. The invention can transmit and receive the program preview information in real time.

Description

technical field [0001] The invention relates to the field of digital mobile communication, in particular to a multimedia program preview information sending system, a receiving terminal and a method thereof. Background technique [0002] In recent years, digital mobile multimedia broadcasting technology and standards have developed rapidly, such as DVB-H (Digital Video Broadcast Handheld, digital video broadcasting handheld reception) in Europe, MediaFLO (Media Forward Link Only, media single forward link) in the United States and China's CMMB (ChinaMobileMultimedia Broadcasting, mobile multimedia broadcasting), etc., provide its end users with many services, such as advertisements, weather forecasts, news, sports programs, variety shows, multimedia radio dramas, movies and other programs. Multimedia broadcasting service programs. [0003] Mobile multimedia broadcasting technology uses time-division multiplexing to send multimedia broadcasting services. The broadcast channe...
