<p>A method and apparatus for embedding of JAVA bytecode data in a transport stream is described. To ensure the concurrent delivery of bytecode, the information is embedded within spaces allocated in the transport stream, or in packets that carry the media data. In one embodiment of the invention, media data is grouped in structured packets referred to as Packetized Elementary Stream (PES) packets. In one embodiment of the invention the pre-defined space is allocated within the header segment of PES packet. In another embodiment bytecode instructions are embedded within a private stream segment of a PES packet. One transport stream used with the invention is an MPEG-2 transport stream that includes structured packets that transport the PES packets. In an embodiment of this invention bytecode can be embedded in a transport stream header or a transport stream payload segment. In other embodiments, bytecode data is transmitted in the private stream segment and retransmission of bytecode is accomplished in other regions of the PES packet. In anoter embodiment, bytecode data is transmitted in an adaptation field and retransmitted data is sent as PES header private data.</p> |
