  1. 1. Transcoding H.265/HEVC

    Magister-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Författare :Sina Tamanna; [2013]
    Nyckelord :Transcoding; Transrating; High Efficiency Video Coding; HEVC H.265; Tree Sub-space Search;

    Sammanfattning : Video transcoding is the process of converting compressed video signals to adapt video characteristics such as video bit rate, video resolution, or video codec, so as to meet the specifications of communication channels and endpoint devices. A straightforward transcoding solution is to fully decode and encode the video. LÄS MER

  3. 2. Error Detection for DMB Video Streams

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Ramin Irani; [2013]
    Nyckelord :Digital Multimedia Broadcasting; MPEG-2 standard; MPEG-4 standard; video transport stream;

    Sammanfattning : The purpose of this thesis is to detect errors in Digital Multimedia Broadcasting (DMB) transport stream. DMB uses the MPEG-4 standard for encapsulating Packetized Elementary Stream (PES), and uses the MPEG-2 standard for assembling them in the form of transport stream packets. LÄS MER

  4. 3. Efficient Video Coding Beyond High-Definition Resolution

    Uppsats för yrkesexamina på avancerad nivå, KTH/Ljud- och bildbehandling

    Författare :Jack Enhorn; [2011]
    Nyckelord :;

    Sammanfattning : For good quality Internet video, digital TV, or even mobile video, efficient coding of video signals is required to meet given bandwidth constraints. Today, MPEG-2 and MPEG-4 coding standards are widely used. But to cope with higher than HD resolution more efficient coding is needed. LÄS MER

    Master-uppsats, Datorteknik

    Författare :Peng Xiaoyi; [2011]
    Nyckelord :;

    Sammanfattning : Video decoding technologies have been widely used in our daily life. Higherresolutions and more advanced coding technologies may promote the capabilitiesof video decoding. LÄS MER

  7. 5. Video Decoder Concealment

    Master-uppsats, Institutionen för informationsteknologi

    Författare :Guillermo Arroyo Gomez; [2008]
    Nyckelord :;

    Sammanfattning : H.264 is a new video coding standard developed jointly by ITU – T and the Moving Picture Expert Group (MPEG). It outperforms MPEG-2 by requiring around 50 % of the bit rate for a similar perceptual quality. It allows low bitrate networks to supply video at a quality previously not possible. LÄS MER
