Service discovery mechanism in broadcast telecommunication network
First Claim
1. A method comprising:
- receiving, at a receiver device, a data stream protocol packet that comprises a payload;
inspecting, by a processor, a payload type of the data stream protocol packet;
determining that the payload type indicates that the payload includes a descriptor or section, and, in response, decapsulating the data stream protocol packet;
determining to receive at least one additional data stream protocol packet of the payload type;
repeating the receiving, inspecting, and decapsulating for the at least one additional data stream protocol packet, resulting in a plurality of descriptors or sections that includes data of the data stream protocol packet and additional data of the at least one additional data stream protocol packet; and
generating, at the receiver device, a first descriptor or section based on the plurality of descriptors or sections, wherein the first descriptor or section identifies at least one service available for data streaming from a current cell or from at least one neighboring cell, wherein a length of the first descriptor or section differs from a length of the data stream protocol packet.

Abstract
Aspects of the invention are directed to service discovery in a digital broadcast network. A service discovery descriptor, which may be electronic service guide-provider and cell specific, provides mapping between a service identifier, a logical channel identifier, and a physical channel, which may be characterized by a frame identifier and a slot identifier, that is, each physical channel may have one or more slots within one or more frames. A neighboring service discovery descriptor provides mapping for the service available within neighboring cells. Aspects of the invention are directed to an encapsulation protocol that encapsulates variable length data, including, but not limited to, the service discovery descriptor and the neighboring service discovery descriptor, into fixed length data stream packets.

10. A method comprising:
-
encapsulating, by a processor, signaling metadata and digital broadcast content into payloads of data stream protocol packets, wherein the signaling metadata includes a descriptor or section that identifies at least one service available for data streaming from a current cell or from at least one neighboring cell, wherein a length of the descriptor or section differs from a length of at least one of the data stream protocol packets, wherein a first packet of the data stream protocol packets includes a first portion of the descriptor or section in the payload and a payload type indicating that the payload includes the descriptor or section, and wherein a second packet of the data stream protocol packets includes a second portion of the descriptor or section in the payload and a payload type indicating that the payload includes the descriptor or section, the first portion and the second portion being different portions of the descriptor or section; and causing output of the data stream protocol packets for transmission over a digital broadcast network. - View Dependent Claims (11, 12, 13)
