    摘要: A decoder receives an entry point header comprising plural control parameters for an entry point segment corresponding to the entry point header. The entry point header is in an entry point layer of a bitstream comprising plural layers. The decoder decodes the entry point header. The plural control parameters can include various combinations of control parameters such as a pan scan on/off parameter, a reference frame distance on/off parameter, a loop filtering on/off parameter, a fast chroma motion compensation on/off parameter, an extended range motion vector on/off parameter, a variable sized transform on/off parameter, an overlapped transform on/off parameter, a quantization decision parameter, and an extended differential motion vector coding on/off parameter, a broken link parameter, a closed entry parameter, one or more coded picture size parameters, one or more range mapping parameters, a hypothetical reference decoder buffer parameter, and/or other parameter(s).

    摘要: A luminance component of a video signal is modulated in a first frequency band. A first chrominance component of the video signal is modulated in a second frequency band and is mixed with an audio component. A second chrominance component of the video signal is modulated in a third frequency band. The modulated luminance component, the first modulated chrominance component, and the second modulated chrominance component are then transmitted across a communication link.

    摘要: Data to be impressed upon the average value of a chrominance portion of a block, is replicated at least once. The original and each replica is impressed on blocks in the same block position of separate frames. The frames that have like-positioned blocks that are carrying the same data are considered to be a group. Specific blocks of the frame may be embedded with a particular known data sequence rather than user data. Each group may employ a different known sequence. Instead of simply repeating the data for each like-positioned block of a group, the amount added to the average value for each such block may be changed slightly from frame to frame in group, even when the complexity of the blocks is the same. At a receiver, the multiple instances of the same data bit are extracted and combined to form a single received bit.

    摘要: A data transmission apparatus applicable to transmission of data by the use of a cable of a television camera system or the like and capable of ensuring simplified exact demodulation of data transmitted through quadrature modulation. The apparatus comprises a demodulator for outputting detection signals of the quadrature-modulated signal based on reference signals whose phases are each different by a predetermined value from an I-axis reference signal and a Q-axis reference signal in the quadrature modulation; a signal level corrector for correcting the signal levels of the detection signals; and a signal converter for converting the output signals of the signal level corrector to detection signals based on the I-axis and Q-axis reference signals. An equalizer circuit is further included in the apparatus for adaptively equalizing the output signals of the signal converter or the output signals of the signal level corrector. The quadrature-modulated signal is inputted via a coaxial cable, and the above predetermined value of the phase difference is an angle of 45 degrees.
