Bi-directional transmission of electronic data in TV cable network involves producing local electronic data for distribution to local user interface(s) and downstream transmission data from input data

摘要

The method involves downstream transmission of electronic data from a feed to user interfaces of one or all segments via the cable connection, producing local electronic data for distribution to at least one user interface in a local segment and electronic downstream transmission data for transmission in a high frequency band in an upper region of a cable transmission bandwidth. User data are processed into upstream transmission data. The method involves downstream transmission of electronic data from a feed point to at least some of the user interfaces of one or all segments via the cable connection. A processing device produces local electronic data for distribution to at least one user interface in a local segment and electronic downstream transmission data for transmission in a high frequency band in an upper region of a transmission bandwidth of the cable connection. User data are processed into upstream transmission data. AN Independent claim is also included for the following: (a) an arrangement for use in bi-directional transmission of electronic data in a television cable network.
