    Good night,

    I'm in the planning phase of a wireless video server design. At this
    point, I could not find a single- chip MPEG-2 encoder with easy access
    to its documentation. Some manufacturers had mantained restrictions
    about access this parts documentation, specifically Conexant
    (CX23416); Hitachi (NLC0190BPQ); Fujitsu (MB86393) and NXP
    (SAA6752HS). Does anyone knows a MPEG-2 Encoder with documentation
    available and sold normally in semiconductor market?

    Hi, why not try these following vendors who also make MPEG ICs.

    Toshiba Corp.
    NEC Electronics or

    EMITT Solutions

    You can also try
    Magnum Semiconductor which for sure makes MPEG encoders and lot of
    data is available on their website

    Thank you Srini,

    I've browsed all websites that you sent me, but I could not find links
    with enouth data to evaluate electrical and logical characteristics
    (examples bellow) of each chip. Without this, there is a great risk in
    purchasing a developer kit, for example. Dou you have any other

    Ask the suppliers what qualifications and credentials are needed to
    access the proprietary data, then get those credentials, if you don't
    already have them.

    It is usually an NDA, though sometimes with an "impound" fee that can
    be as high as US$10,000, possibly even more.

    JosephKK : Thank you for your response. This business model is really
    new for me. This US$ 10K is high, and now is necessary to evaluate
    this as a investment.

    Gary Tait: I'm not intended to access private data, but understand how
    MPEG-2 encoders can be brought and used. Remember that there is lots
    of complete datasheets available in the web provided directly by
    chip's manufacturers. Some semiconductors are even more complex than
    MPEG-2 encoders, but this data can be accessed freely and legally by
    any user. I'll evaluate the risk of a +US$ 10K investment, thats all.

    The thing you might be missing is MPEG2 chips require licensing form the
    MPEG-LA, becasue it contains proprietary technology. They don't want just
    anybody to get that info unless they are legtimate and commercially
    serious about possibly using their product and have likely paid for, or
    are on their way to paying for an MPEG-LA license.

    The proprietary technology involved in MPEG-2 itself is protected by
    patents, not trade secrecy.

    The details of MPEG-2 can be found in the patents, or in the source code
    of any software decoder (patentability of algorithms varies between
    countries, as does whether or not source code can infringe a patent).

    The only details likely to be trade secrets are those relating to the
    particular chip, not MPEG-2 per se.

    The other side of the coin is that the fees may not be that high. You
    cannot know until you ask.
