The Program and Systems Information Protocal (PSIP) is the ATSC standard for digital television channel naming, numbering and navigation. DTV Receivers use PSIP information to tune and label digital and analog channels. See pictures from of a variety of set-top boxes and instructions for properly implementing PSIP. Sample PSIP from Sharp TV-DTV1000 Receiver SERVES All DTV receivers. No Digital Cable set-top-boxes. DTV PSIP has no effect on digital cable systems choosing to carry DTV broadcasts. Cable set-tops ignore DTV PSIP and instead use a separate navigation system. INGREDIENTS 1 - PSIP Generator Digital Vision - BitLink PSIP Generator Harris - PSIPplus NDS - StreamServer Triveni - GuideBuilder Thomcast - Pearl 2 - Multiplexor Choose Upstream or Downstream. Upstream uses the Multiplexor that is part of the encoding system. Downstream uses an additional multiplexor downstream from the encoding multiplexor. (See drawing below.) Logic Innovations - Transport Stream Multiplexer 3 - PSIP Generator/Mux Interface Choose UDP-Ethernet or ASI: UDP is a less-expensive interface. Some multiplexors require ASI. 4 - Data for Each Transmitter Transport Stream Identifier (TSID): This is a unique code assigned by MSTV for every digital and analog transmitter. It helps a receiver to differentiate between stations when the frequency is changed by a cable system or translator. RF Carrier Frequency: Be careful - some PSIP systems ask you to enter the frequency of the lower band edge, others the DTV pilot and some the center of the band. 5 - Data for Each Program Service Major Channel Number: Usually chosen for all services to be the same as the analog channel number. Minor Channel Number: An analog transmitter has one video/audio program service with a minor number of 0. A digital transmitter can have multiple program services with minor numbers from 1 to 99. Each service has any number of audio channels, with or without video. Service Short Name: This is the channel name shown to viewers when they surf or view an Electronic Program Guide. It must be seven characters or less. Some receivers show fewer than seven characters in certain modes. Logically, this name should match the "brand" used to promote the channel. Service Description: Longer description of program service, up to 255 characters. Only available on some receivers. INSTRUCTIONS 1 - Install Install equipment and interfaces. 2 - Configure Enter data gathered above into relevant tables. 3 - Test Test your transmission on a wide variety of receivers. Submit your stream for independent testing. It is easy to set a PSIP system so that some receivers work, while others do not.
