Content-Aware Adaptive Media Playout Controls for Wireless Video Streaming

Low-cost tiled display system architecture with dynamic web-based management

“…Moreover, the AMP adjustment technique is performed by increasing/decreasing 10% of the playout nominal rate. According to [37,38], playout rate variations of up to 25% are not noticeable by users. The value of 10% has been chosen after testing several values lower than 25% in the lab.…”

Block Recovery Rate-Based Unequal Error Protection for Three-Screen TV

“…To adapt time-varying channel environments, an optimal packet scheduling for rate-distortion was proposed [14][15][16][17]. Also, a rate-distortion optimized scheduling algorithm was presented to adapt the streaming video over time-varying channels for minimizing the total distortion under the transmission rate constraint [18,19]. There have been research studies on transmitting SVC video sequence safely over multicast channel or MIMO wireless systems using Raptor codes [20][21][22], research studies on the priority-based SVC or SHVC video streaming over multi-channel were introduced in [23,24], and research studies on the UEP method with Raptor codes with SVC or HEVC temporal layer priorities have been presented in [25][26][27][28][29].…”

“…Figure 6 shows the hierarchical prediction structure of scalable video. distortion optimized scheduling algorithm was presented to adapt the streaming video over timevarying channels for minimizing the total distortion under the transmission rate constraint [18,19].…”

Implementation and Evaluation of an M/S Scheme for Inter-Destination Multimedia Synchronization (IDMS)

“…[17] and [18]) and, occasionally, for inter-stream sync purposes [19]. However, in [3], authors proposed to extend the use of AMP for IDMS purposes, since this technique can enable distributed receivers to adjust their playout timing (playing the media faster/slower than normal), within perceptually tolerable ranges, in order to smoothly acquire an overall sync status every time an asynchrony threshold between their playout states is exceeded.…”

“…Previous related subjective tests have shown that playout speed variations of up to 25% are often unnoticeable and, depending on the content and the frequency of the adjustments, variations up to 50% are sometimes acceptable ( [17] and [18]). Thus, we assume in our simulation tests that video playout adjustments up to 25% lead to unnoticeable quality impairments, and we define a playout factor (φ) to specify this variation ratio.…”
