OPB provides the community with a variety of resources and services so that all of our viewers and listeners can enjoy our programming. We are also involved with the Emergency Alert System to keep everyone informed of the latest information related to many types of emergency situations.

Closed Captioning

  • Closed captioning is designed to assist deaf or hearing-impaired people, English Language Learners, young children learning to read and many others by displaying the dialogue or transcript of the audio portion of the program as printed words on the television screen.
  • To determine whether a program is closed captioned, look for the symbol “CC”in the "Find a Program" section on our Web site.
  • You can turn on closed captioning using either a set-top decoder or a caption-ready TV set.
  • Read more about closed captioning on Wikipedia.
  • To report an issue with closed captioning, please do the following:
    • Jonathan Edmonds, Director of Engineering, Net Center 7140 SW Macadam Avenue Portland, OR 97219 Tel: 1.503.293.4010 Email: Jonathan Edmonds (include "closed captioning" in subject line)
    • Please make sure that your report includes all of the following:
      • your name, address, and other contact information, such as phone number or e-mail address;
      • the website address of the video (if applicable), or the TV channel number and call sign of the station broadcasting the program (if applicable);
      • the name of the subscription service, if you pay to receive television;
      • the date and time of the captioning problem;
      • a detailed explanation of the closed captioning problem;
      • the name of the program or video with the captioning problem; and
      • whether you would prefer to be contacted by email, regular mail or phone.

Described Video Information (DVI)

  • Described Video Information is designed to assist people who are blind or visually impaired. In a program with described video, a narrator may describe the setting, identify who is speaking, relay action taking place and provide other relevant information. The description is carefully timed so that it does not interfere with the dialogue or program narration. Some OPB local productions have described video.
  • To determine whether a program has described video, look for the symbol "DVI" in the OPB Member Guide or in the "Find a Program"section on our Web site.
  • You can hear described video through OPB TV's Second Audio Program (SAP) channel. The SAP channel is accessed through a stereo television set or the newer VCRs. Some stereo televisions have a switch that will activate the SAP channel, while other sets and many VCRs have a menu item that will say “Stereo/SAP.” SAP is not available for digital television services such as high-definition television (HDTV).

Accessing the SAP Channel

  1. Check the Table of Contents in your TV or VCR manual for a listing of "Secondary Audio Programs," sometimes listed as SAP or MTS.
  2. Once you have located that information, turn on your TV and tune to OPB.
  3. Follow the directions in your TV manual to access the Secondary Audio Program Channel.
