Embodiment 1

[0035] This embodiment will be described from the perspective of a terminal, and the terminal needs to support obtaining pictures in an interactive manner.

[0036] A method for transmitting picture information. The picture information is obtained. The picture information carries a hyperlink and an identifier of the hyperlink. According to the identifier of the hyperlink, it is judged whether the hyperlink has been processed. If so, the link is obtained locally. The corresponding picture, and display the obtained picture according to the picture information, if not, request the network side to obtain the picture according to the hyperlink, and display the obtained picture according to the picture information. Such as figure 1 As shown, the specific process can be as follows:

[0037] 101. Obtain picture information, the picture information carries a hyperlink and a hyperlink identifier, and the hyperlink identifier has a one-to-one correspondence with the hyperlink;

[0038]...

Embodiment 2

[0055] According to implementing a described method, the TG system will be taken as an example for detailed description below. The TG system needs to support obtaining pictures through interactive methods.

[0056] In order to describe more clearly, in this embodiment, the hyperlink described in Embodiment 1 will be described as an image address. It should be understood that, in fact, the hyperlink of the picture may not only be the address of the picture, but also the trigger address of a certain device. Then, when the terminal requests the network side device to obtain the picture and clicks on the hyperlink, the "certain device " is triggered, and then the associated picture is called to the network side device, and the network side device sends the picture to the terminal, wherein the network side device can be a TG head end, and the terminal can be a TG device.

[0057] First, the picture address is carried in the RTP packet in a fixed format as a content of the TG syste...

Embodiment 3

[0102] In order to better implement the above method, the embodiment of the present invention also provides a terminal correspondingly, such as Figure 5 As shown, the terminal includes an acquisition unit 301, a processing judgment unit 302, a request unit 304, and a display unit 305;

[0103] The acquiring unit 301 is configured to acquire picture information, wherein the picture information carries a hyperlink and an identifier of the hyperlink; for example, a picture stream sent by the network side may be received, wherein the picture stream is carried in RTP mode, and the picture stream Independent of the video content transmission stream; after receiving the picture stream, the terminal parses the picture stream and judges whether the picture stream carries pictures or picture information. If it is a picture, it processes the picture, such as displaying the picture, etc. If it is picture information, the picture information is acquired and the picture information is furt...

Abstract

The invention discloses a method, a device and a communication system for transmitting picture information. The technical scheme of the invention is as follows: a hyperlink carried in the picture information and an identifier of the hyperlink are adopted, so that a terminal can judge whether the hyperlink is processed or not according to the identifier of the hyperlink when receiving the picture information and request a picture from the network side according to the hyperlink when determining the that the hyperlink is not processed, thereby effectively reducing the bandwidth consumption for a broadcast or multicast channel, simultaneously effectively preventing the terminal from reprocessing and displaying the same hyperlink and reducing the processing complexity of the terminal.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a transmission method, device and communication system for picture information. Background technique [0002] With the development of digital broadcasting and television technology and the integration of communication services, the forms of media are more colorful. In addition to traditional audio and video, it can also include text, graphics, animation and support for user interaction. These additional subtitles and graphics can provide users with value-added services such as movie subtitles, titles, additional information prompts, advertisements and notifications. [0003] For the display of these integrated contents, there are different implementation schemes and technical standards. Typically, a head-end system is responsible for completing all integrated processing solutions, and the terminal supports Rich Media technology to realize the presentation of variou...
