Address assignment in digital transmission system
First Claim
1. A method of transmission of digital information in a digital broadcast system comprising a central transmission station and at least one decoder, the central station transmitting at least one transport stream comprising a stream of packets encapsulating data sections within their payloads, wherein at least one encapsulated section includes at least one medium access control (MAC) address used to control the reception thereof by the at least one decoder, wherein the at least one MAC address is dynamically assigned by the central transmission station and communicated to said at least one decoder using a fixed internet protocol (IP) address in an address assignment message, wherein the at least one MAC address is based on a type of service requested by the decoder, wherein the type of service requested is one selected from the group consisting of a multicast service, a connected unicast service and a non-connected unicast service.

Abstract
A method of transmission of digital information in a digital broadcast system including a central transmission station and one or more decoders, the central station transmitting at least one transport stream comprising a stream of packets encapsulating data tables or sections within their payloads, one or more encapsulated sections including a medium access control (MAC) address used to control the reception of that section by one or more decoders wherein the MAC address is dynamically assigned by the central transmission station and communicated to the or each decoder in an address assignment message using a fixed IP address.

18. A method of communication of datagram packets in a digital communication network comprising at least one central control station and a plurality of remote terminals, in which the datagram packets include at least one medium access control (MAC) address associated with one communication layer of the network and an internet protocol (IP) address associated with a second communication layer of the network, and in which the at least one MAC address is dynamically assigned by the central control station in response to a request from a remote terminal, wherein the at least one MAC address is assigned based on a type of service requested by a remote terminal, and wherein the type of service is one selected from the group consisting of a multicast service, a connected unicast service and a non-connected unicast service.
- 19. Apparatus for transmitting a transport stream comprising a stream of packets encapsulating data sections within their payloads to a decoder, at least one encapsulated section including at least one medium access control (MAC) address used to control reception thereof by a decoder, said apparatus comprising means for dynamically assigning the at least one MAC address, and means for communicating to said decoder the at least one MAC address using a fixed IP address in an address assignment message, wherein the at least one MAC address is assigned based on a type of service requested by a remote terminal, and wherein the type of service is one selected from the group consisting of a multicast service, a connected unicast service and a non-connected unicast service.
