This course examines the delivery of TV images for SDTV and broadcast quality where MPEG-2 has been used for many years. However to deliver higher resolutions without more bandwidth greater compression is needed so the course will examine advance Video encoding, MPEG-4 and H.264. Also in the field of handheld mobile devices the data rates over wireless channels are considerably reduced by the deployment of error recovery techniques. Here compression is vital to deliver any viable image service.
Broadcasting systems depend upon delivery over MPEG transport streams so the course will examine how MPEG-2 transport streams can be used to carry services encoded in MPEG-2, MPEG-4 and H.264. It will provide an understanding of how service information is delivered and how conditional access is encoded. The course will also examine the architecture of set top boxes and address the issues of middleware and chip-sets.
