    摘要: Provided are a method of tuning a coding rate and applying an unequal error protection for an adaptive video transmission, and a video transmission/reception apparatus using the method. The video transmission apparatus may include: a coding rate tuner to predict, as a channel capacity of a subsequent channel interval, an estimated channel capacity value fed back from the video reception apparatus, and to tune video and channel coding rates within the predicted channel capacity; a video encoder to perform video encoding of video frames at the tuned video coding rate, and to generate a video packet; and a forward error correction (FEC) encoder to apply the unequal error protection based on a length of the video packet and a type of the video frames included in the video packet, and to perform channel encoding of the video packet at the tuned channel coding rate to generate a bitstream.

    摘要: A video communication apparatus in which eye contact can be made with an opposite party of a conversation is provided. The video communication apparatus includes: a monitor unit for video communication; and a camera unit for capturing an image of a user, wherein the monitor unit repeats mode switching between a video mode and a transparent mode according to a specific period, and wherein the camera unit is located behind the monitor unit and captures the image of the user by using a screen of the monitor unit. Accordingly, eye contact can be made with the opposite party when users who participate in video communication talk to each other while seeing communication images.
