A major problem in low-latency Audio over IP transmission is the unpredictable impact of the underlying network, leading to jitter and packet loss. Typically, error concealment strategies are employed at the receiver to counteract audible artifacts produced by missing audio data resulting from the mentioned network characteristics. Known concealment methods tend to achieve only unsatisfactory a...

We introduce model-based schemes for error concealment of networked video. We build appearance models for specific objects in the scene and use these models to replenish any lost information. Due to the models being designed specific to the object, they are able to capture the statistical variations in the object appearance more effectively, thereby leading to better error concealment performan...

The MPEG-2 video compression standard is commonly used in real-time video transmission. In real-time video transmission, a little bit error can cause huge data lost in the video sequence. The errors and data loss degrade the quality of video. The error concealment method is useful to overcome the errors in the broken slice of MPEG-2. In this paper, we present an efficient error concealment algo...

Error concealment on the end of decoder, which makes use of the correctly received video data to conceal the lost video, does not need any redundancy data and has no impact to bandwidth of network. A new concealment method based on multiple motion predictions is proposed here. In this paper, motion vectors in the past and/or future frames are used to achieve the current motion vectors when the ...

The present research tests a model derived from self-determination theory to explain why self-concealment (the tendency to keep distressing personal information secret) is associated with negative well-being outcomes. Two studies tested a model in which self-concealment predicts the thwarting of basic needs for autonomy, competence, and relatedness, which then results in negative psychological ...

We introduce the concept of “marketing avoidance” – consumer efforts to conceal themselves and to deflect marketing. The setting is one where sellers market some item through solicitations to potential consumers, who differ in their benefit from the item and suffer harm from receiving solicitations. Concealment by one consumer induces sellers to shift solicitations to other consumers, while def...

Error concealment for stereoscopic images receives little attention in research of image processing. While many methods have been proposed for monocular images, this paper considers a concealment strategy for block loss in stereoscopic image pairs, utilizing the information of the associated image to fulfill the higher quality demand. We present a hybrid approach, combining a 2D projective tran...

The problem of error control and concealment in video communication is becoming increasingly important because of the growing interest in video delivery over unreliable channels such as wireless networks and the Internet. This paper reviews the techniques that have been developed for error control and concealment in the past 10–15 years. These techniques are described in three categories accord...
