Pet -priority Encoding Transmission: a New, Robust and Eecient Video Broadcast Technology

چکیده
This paper presents a new Forward Error Correction Scheme with several priority levels. It is useful for applications dealing with real-time transport streams like video and audio. Those streams consist of several data parts with diierent importance. PET allows to protect those parts with appropriate redundancy and thus guarantees, that the more important parts arrive before the less important ones. In the video we show the impacts of losses to an MPEG 2] video stream with and without PET protection. Due to the fragile nature of MPEG the unprotected stream breaks up, the PET protected stream is unaaected by low losses and jerky when high losses are present.

Robust Transmission of MPEG Video Streams over Lossy Packet-Switching Networks by using PET
Network heterogeneity is a major issue and multimedia applications have to deal with interconnected networks consisting of many sub-networks of non-uniformly distributed resources. Real-time traffic caused by video sources is bursty by nature, resulting in buffer overflow at the switch and unavoidable packet losses. Therefore the information is desirable be compressed and prioritized in a way t...
متن کاملAbout priority encoding transmission
Recently, Albanese et al. introduced priority encoding transmission (PET) for sending hierarchically organized messages over lossy packet-based computer networks [1]. In a PET system, each symbol in the message is assigned a priority which determines the minimal number of codeword symbols that is required to recover that symbol. This note revisits the PET approach using tools from network infor...
متن کاملA New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...

Multiple description (MD) coding has evolved as a promising technique for promoting error resiliency of multimedia system in real-time application programs over error-prone communicational channels. Although multiple description lattice vector quantization (MDCLVQ) is an efficient method for transmitting reliable data in the context of potential error channels, this method doesn’t consider disc...
