Decoder State-Copying for Bluetooth CVSD Packet Loss Concealment
نویسندگان
چکیده
This paper describes a novel packet loss concealment (PLC) algorithm for Bluetooth CVSD codec by updating decoder states efficiently through state-copying. In the proposed method, the decoder states are stored in buffers and then selected based on the estimated pitch period of the decoded signal. The selected states are used to reset the decoder states when the packet is lost or corrupted. Objective evaluations show the proposed algorithm consistently outperforms the decoded domain PLC algorithm. Keywords-state copy; packet loss concealment; CVSD; Bluetoot;, speech enhancement

Adaptive Spectral Separation Two Layer Coding with Error Concealment for Cell Loss Resilience
This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...
متن کاملEfficient three-stage pitch estimation for packet loss concealment
This paper presents a low-complexity pitch estimation algorithm for packet loss concealment. The algorithm divides the pitch estimation into three stages with each additional stage providing further accuracy. Compared with a system based on G.711 Appendix I, the proposed algorithm requires approximately 32 percent fewer cycles on a DSP processor integrated in a Bluetooth chip. Furthermore, obje...
متن کاملEffect of Using Different Encoders in Bluetooth
IEEE 802.11 and Bluetooth are the two different wireless systems that share the same frequency band in 2.4 GHz and are likely to interfere with each other if operating in the same environment and thus experience a severe decrease in throughput. The devices equipped with IEEE 802.11 and Bluetooth are mobiles, laptops, watches and many more and in future with WiMAX. Result is the number of co-loc...
متن کاملSwitched Error Concealment and Robust Coding Decisions in Scalable Video Coding
This work introduces two complementary techniques to improve the packet loss resilience of scalable video coding systems. First, a “switch per-pixel” error concealment (SPEC) scheme is proposed, which allows the decoder to exploit information from both the current base layer and previous enhancement-layer frame for the reconstruction of missing enhancement-layer blocks. Based on the packet loss...
متن کاملError Control and Concealment of Jpeg2000 Coded Image Data in Error Prone Environments
In this contribution we investigate the error robustness tools offered by the JPEG2000 coding standard. Error robustness is supported on entropy coding level and packet level. A synchronization loss caused by a packet loss can be prevented if marker segments are inserted into the code stream. However, a packet loss and the related loss of wavelet coefficients causes a severe visual distortion. ...
