The phrase "a video packet" is correct and usable in written English.
It can be used in contexts related to data transmission, networking, or multimedia communication, where packets of video data are being discussed.
Example: "The streaming service experienced delays due to the loss of a video packet during transmission."
Alternatives: "a video frame" or "a video data unit".
In the procedures of video packetization, the importance of a video packet can be marked as either high or low priority, so that it can be scheduled and delivered differently in lower layers.
Based on the simulation results obtained in this study, the proposed scheme can recover high-quality H.264/AVC video frames from the corresponding corrupted video frames up to a video packet loss rate of 20%.
For example, a cell can be labeled as a video packet, a voice packet or a data packet.
As aforementioned in Section 3.1, the priority of a video packet is determined according to (2), i.e., the DVFI value of its associated video frame.
Instead, when a video packet arrives at MAC, any AC queue which has the shortest estimated delay time among all the ACs will be selected to serve the video packet.
Essentially, the increase in distortion due to the loss of a video packet is a function of all the other video packets that are dependent on it and cannot be decoded if it is not sent.
The second metric, end-to-end delay, states the transmission time between sending and receiving a video packets in the video server and an applicant node, respectively.
In the proposed I-EPD, an IN can intelligently determine whether a buffered video packet should be early discarded.
This assumption may not be perfect for a precise video packet importance, but is at least a much better one than the existing works, and good enough for our proposed cross-layer design to win. Figure 7 Frame population based N + 1 grouping of DVFI ( N = 5, i.e., 5 prioritized groups for P frames and 1 top-priority group for I frames).
This article proposed a novel cross-layer design called DVFI+CQM, where a hyperfine video packet priority scheme based on the concept of dispersive video frame importance (DVFI) was adopted in the application layer while a corresponding AQM-based packet mapping function called comb-shaped quadratic mapping (CQM) was proposed in the MAC layer.
Given a fixed video packet size Lv, each video traffic burst is segmented into a batch of packets that arrive simultaneously.
