An implementation of streaming video in HTML Web pages combines video signals in MPEG digital television format with Internet World Wide Web pages in HTML format. Internet streaming video is transcoded into MPEG-2 digital video format and multiplexed along with other MPEG-2 digital video signals for transport within a multiple channel digital video system. A navigational control map, transmitted from the headend to the CATV set-top box in a fixed location in the MPEG-2 video data stream, permits the CATV set-top to find the requested video clip in a predetermined Packet Identifier of the MPEG-2 data stream. The viewer controls the video clip (e.g., play, pause, resume, restart etc.) during the session. The set-top transmits control commands to the headend. The disclosed arrangement allows the available MPEG-2 decoder hardware in the CATV set-top box to be used to display streaming video without requiring additional hardware or additional RAM memory.
