Embodiment Construction

[0014] figure 1 is a block diagram of a system including an adaptive transport decoder according to the present invention. exist figure 1 , respective outputs of a plurality of packet stream sources 10 are coupled to respective inputs of a selector 20 . An output of selector 20 is coupled to an input of adaptive transport protocol decoder 30 . An output of adaptive transport protocol decoder 30 is coupled to an input of payload processor 40 . An output of payload processor 40 is coupled to an input of user interface 50 .

[0015] In operation, packet source 12 generates a stream of packets, each including a payload (described in detail below) and having a first transport protocol, and packet source 14 generates packets, each including a payload and having a second transport protocol. Multiple packet stream sources 10 may include additional packet stream sources, such as packet stream source 1N, generating respective packet streams, each including a payload and having a cor...

Abstract

An adaptive transport protocol decoder includes a source (12) of a stream of packets, each including a payload, and having a first transport protocol, and a source (14) of a stream of packets, each including a payload, and having a second transport protocol. A protocol decoder (30), coupled (20)to the first and second packet stream sources, extracts the respective payloads from the packets from a selected one of the first and second packet stream sources.

Description

technical field [0001] The invention relates to a transport packet decoder for adaptively decoding packets with different transport protocols. Background technique [0002] Currently, digital signals carrying programs such as video / audio / data programs are provided to consumers from different providers in correspondingly different formats, called protocols. For example, the format of the direct satellite system (DSS, direct satellite system) signal is a proprietary format owned by DirecTV, and the format of all signals carrying programs provided by DSS satellites uses this protocol. Similarly, the local terrestrial (local terrestrial) high definition television (high definition television, HDTV) format is based on the original proposal by the Advanced Television Standards Committee (ATSC, Advanced Television Standards Committee) and by the US Federal Communications Commission (FCC, Federal Communications Commission ) approved standard, the standard protocol is used for the f...
