This dissertation study describes and presents an alternative method for delivering digital video, the MPEG-4 compression format, through the use of an analog cable network for direct viewing on television sets. The purpose of the study is to propose this technology as an alternative to the present cable network technologies in Uruguay and elsewhere in South America. Delivery standards that might be used over such a CATV network include DVB-C (digital video broadcast for cable), and IP (internet protocol) networks.
The study compares the current technologies to determine which would be the best way to provide such delivery over CATV networks. It is the argument of this study that the delivery of MPEG-4 format streaming video is no different than the delivery of any type of digital signal: in order for the signal to be delivered, it must pass through a transmission medium such as fiber-optic cable, twisted-wire pair, coaxial cable, etc.
The dissertation makes the case that MPEG-4 is a feasible alternative technology which should be considered for new CATV applications in this region. This study is from a technical point of view, when it comes to implementation there are other elements that should be taken into account. |
