System and method of providing triggered event commands via digital program insertion splicing
Systems and methods for the insertion of commands and/or other data into a digital programming stream are described. These command and/or data may be inserted into digital advertisement or other programs and may utilized by any device which is involved in the generation, transmission, reception and/or presentation of content via a digital programming stream.
1 . A system for inserting commands into a digital programming signal comprising:
a digital ad server which generates at least one message having an attached command; and
a digital splicer which receives the message from the ad server, extracts the attached command and splices the command into a digital transport stream.
2 . The system of claim 1 , wherein the message further comprises a message which is in a DVS380 compliant format.
3 . The system of claim 2 , wherein the DVS380 compliant message includes at least one descriptor.
4 . The system of claim 3 , wherein the DVS380 message further comprises a DVS380 splice request message.
5 . The system of claim 4 , wherein the descriptor includes at least one field for inserting a command instruction.
6 . The system of claim 5 , wherein the descriptor includes at least one field for specifying a time difference from a reference time at which to insert the command into a digital transport stream.
7 . The system of claim 1 , wherein the digital ad server generates at least one message having more than one commands.
8 . The system of claim 1 , wherein the message further comprises a delta time indication from a pre-determined reference and the digital splicer splices the command into a digital transport stream based upon a calculation of the delta time with the reference and the current time.
9 . The system of claim 1 , wherein the command is spliced into the digital transport stream on a frame accurate basis.
10 . The system of claim 1 , wherein the message is in the DVS380 standardized message format and the command is provided in a descriptor field.
