Embodiment 1

[0039] The feature of the first embodiment is that the data of the preview picture is added in the SG.

[0040] Such as figure 1 As shown, the preview image transmission system includes an SG server and a terminal; wherein, the SG server is located in the TD-MBMS platform, and the terminal mainly refers to mobile phones, data cards, MP4, etc. that support TD-MBMS functions and video reception. The communication between the SG server and the terminal is carried on the TD-SCDMA (Time Division Synchronous Code Division Multiple Access) network.

[0041] The method for transmitting the preview image includes the following steps:

[0042] Step 101, the SG server generates the SG according to the video file, and adds the data of the preview picture in the video file to the SG; specifically, adds the data of the preview picture to the PictureData (picture data) of the PreviewData (preview data fragment) of the SG in the label;

[0043] The video file is sent from the video service...

Embodiment 2

[0050] The second embodiment is characterized in that the description information file and the preview image are not encrypted.

[0051] Such as figure 2As shown, the transmission system for preview pictures in video files includes TD-MBMS platform and terminals; terminals mainly refer to mobile phones, data cards, MP4, etc. that support TD-MBMS functions and video reception. The communication between the TD-MBMS platform and the terminal is carried on the TD-SCDMA network.

[0052] The method for transmitting the preview image includes the following steps:

[0053] Step 201, the TD-MBMS platform generates SG according to the video file, and encrypts the video file except the file description table, description information file and preview picture;

[0054] The video file is sent from the video service platform to the TD-MBMS platform;

[0055] Step 202, according to the request of the terminal, the TD-MBMS platform sends the SG to the terminal;

[0056] In practical appl...

Embodiment 3

[0067] The characteristic of the third embodiment is that the description information file and the preview picture are sent by the SG server through the interactive network, and sent together with the SG.

[0068] Such as figure 1 As shown, the preview image transmission system includes an SG server and a terminal; wherein, the SG server is located in the TD-MBMS platform, and the terminal mainly refers to mobile phones, data cards, MP4, etc. that support TD-MBMS functions and video reception. The communication between the SG server and the terminal is carried on the TD-SCDMA network.

[0069] The method for transmitting the preview image includes the following steps:

[0070] The SG server generates SG according to the video file, and does not encrypt the description information file and preview picture in the video file;

[0071] The video file is sent from the video service platform to the TD-MBMS platform, and the description information file and preview picture in the v...
