摘要: A method of transmission of application data (97) in a digital transport stream characterized in providing an application data table (110) containing information regarding the applications (97) carried in each service (91, 92) within the transport stream. The application data table (110) may conveniently be designated by a fixed PID value and a TID extension value varying in dependence on the bouquet of services chosen. The use of a single application data table to provide information across all services within a bouquet provides a number of advantages, in particular when deciding whether or not to maintain certain applications when switching between services.

摘要: A method of transmission of digital information in a digital communication network, the network comprising at least one transport stream carrying one or more bouquet related tables such as BAT tables (53, 54) containing information regarding the services provided in a commercial bouquet and characterised in transmitting at least one table (51) comprising a list of bouquet identity values of some or all of the bouquet association tables together with an indication of the or each transport stream carrying that table or tables. In a particularly preferred embodiment, the table (51) containing a list of bouquet identity values may correspond to the Network Information Table of a network. The present invention also extends to the identification of any fixed PID, TID tables that may only be distinguished by their TID extension values. The present invention is particularly applicable to digital television systems conforming to the MPEG-2 and DVB proposed standards.
