Embodiment Construction

[0028] The embodiment of the present invention utilizes the existing videophone technology and unit to realize the function of sending text information to the opposite end during the videophone call. Text messaging is compatible with existing videophone technology and units. Moreover, the sending of the text message will not affect the normal videophone conversation process, and the video call can still be carried out normally during the text message sending period.

[0029] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] This example utilizes as figure 1 and figure 2 The structure model of the existing videophone is shown, and the function of sending text information is added on the basis of the structure model of the existing videophone.

[0031] see image 3 , the preferred embodiment of the present invention videophone system includes a videophone sender 10, the videophone sender 1...

Abstract

The invention discloses a video telephone, a system and a method for realizing a word message sending function during video communication. The video telephone comprises a word message processing unit, a video input unit, a video code stream synthesis unit, a video coding unit and a modem unit, wherein the video input unit is used for collecting video data of a sending terminal user, the word message processing unit is used for inputting word messages to be sent and transforming the word messages to video data of a video format adopted by the video input unit, the video code stream synthesis unit is used for processing video data output by the video input unit and video data output by the word message processing unit in a superposed way so as to form new mixed video data with word messages, and the video coding unit is used for coding the new mixed video data with word messages and transmitting the new mixed video data with word messages to a receiving terminal by the modem unit. The invention can meet the requirement of realizing word input during the video communication.

Description

technical field [0001] The invention relates to the field of videophone communication, in particular to a videophone, a system and a method for realizing the function of sending text information during a videophone call. Background technique [0002] Videophone is a multimedia communication system that integrates audio and video. With the development of the third generation (3G) mobile communication technology, people are no longer satisfied with ordinary voice telephone services. Telephones have been used by more and more people. [0003] figure 1 Shown is a structural schematic diagram of the existing videophone sending end. As shown in the figure, the audio and video input unit encodes and compresses the collected data through the encoding unit, and the multiplexing unit (h.223 multiplexing unit) multiplexes the encoded audio and video data through the modem send to the other party. [0004] figure 2 Shown is a schematic diagram of the structure of the existing vide...
