Artifacts around text when viewing a Jpeg image on a HDTV?

I'm new to this kind of advertising media. So bare with me. I'm creating these 1920 x 1080 @ 96dpi Photoshop images that has black text on white background that are viewed on a LCD HDTV. The images are saved out as Jpegs at the highest quality setting. When I view the image on the HDTV, I see all kinds of artifacts around text. (See attached image sample that I shot with a digital camera of the HDTV screen.) Let me add that I do not see any of the artifacts around the text  when I view the Jpeg image on my computer's monitor.

 

So is this something inherit to this kind of media? Or I'm I missing a setting somewhere? It would be nice if I could diminish the artifacts to a lesser amount at least.

 

Thanks,

    That's the nature of JPEG compression, even at the highest quality level.

     

    The HD TV obviously magnifies the artifacts.

     

    I know nothing about TV or video, I just avoid the JPEG format at all costs myself, unless someone or something absolutely demands a JPEG from me, in which case I only generate the abomination as the final output file.  Try working with PNG files instead—if your intended application permits it.

    I agree, and it's why I do not use JPEG, unless the client's needs absolutely dictate it.

     

    I do a lot of Image work (tons of Titles) in PS, that goes to both DVD-Video and BD (Blu-ray Disc), and never, never introduce JPEG into the workflow. Everything that I output is PSD (or maybe a very few PNG's).

     

    However, from the last response from iRuss, PSD will not be an option either.

     

    As a bit of an after thought, perhaps iRuss could produce a Premiere Pro (or Elements) AV file for the SlideShow and Titles, and put an H.264 in an MP4 "wrapper" file on the thumbdrive? Then, a PSD could be used effectively in the video.

     

    Just thinking here,
