A conference terminal, a conference server, a conference system, and a data processing method are provided. The conference terminal includes: a mark obtaining module, configured to obtain a mark data signal; an image obtaining module, configured to obtain an image data signal; a superimposing module, configured to superimpose the mark data signal onto the image data signal to generate a hybrid image data signal; and an outputting module, configured to output the hybrid image data signal. The present invention improves the interactivity between videoconference users and the discussion efficiency.

A method and an apparatus for processing images are disclosed. The method includes: generating an image histogram of an image to be processed; judging whether the image to be processed requires backlight compensation according to the image histogram; if the image to be processed requires backlight compensation, determining a first luminance boundary value A used for deciding whether to perform backlight compensation and a second luminance boundary value C used for deciding whether to perform positive or negative backlight compensation; and performing backlight compensation for the image to be processed according to the first luminance boundary value A and the second luminance boundary value C. The method is simple and universally applicable. After backlight compensation, the contrast of the image is high, and the image is free from background overexposure and image layering. The image photographed in a backlight environment is processed properly.

Forward Error Correction (FEC) coding is performed on data packets to generate verifying packets; corresponding information independent of a packet sequence number (SN) and denoting a corresponding relation between the data packets and the verifying packets is carried in the data packets, or in the verifying packets, or in the data packets and the verifying packets; the data packets and the verifying packets are transmitted by using a protocol based on a User Datagram Protocol (UDP). A method for receiving data packets and devices for transmitting and receiving data packets are further described. Thus, a receiving terminal correctly can recover lost data packets after a relay device modifies the packet SN.
