    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.

    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.
