摘要： In accordance with a first embodiment of the invention, a method for editing video is provided. In accordance with the invention, a previously compressed first digital video bit stream is decoded to obtain a decoded digital video signal. In response to statistical values which characterize the previously compressed first digital video bit stream, the decoded digital video signal is re-encoded to form a second digital video bit stream such than an ending fullness of a vbv does not fall below a predetermined threshold. Optionally, an effect may be added to the decoded digital video signal before re-encoding. A second embodiment of the invention is directed to a method for splicing a first compressed digital video bit stream and a second compressed digital video bit stream. The first compressed digital video bit stream has a plurality of entry points. Each of the entry points has an associated threshold buffer fullness, such that if an actual vbv fullness, just before removal of the bits of a first picture following the entry point equals or exceeds the associated threshold fullness, the portion of the first compressed digital bit stream following the entry point may be decoded without causing the vbv to underflow. Using an encoder, the second compressed digital video bit stream is generated. The second compressed digital video bit stream results in an ending fullness of a vbv one picture time after removal of the bits corresponding to a last picture of the second compressed digital video bit stream. This ending fullness equals or exceeds the threshold fullness associated with one of the entry points. The first and second compressed digital video bit streams are then spliced so that the last picture of the second compressed digital bit stream is immediately followed said one of the entry points in the first compressed digital video bit stream. A third embodiment of the invention provides a method and system for determining and recording a minimal ending vbv fullness at each of a plurality of entry points in a compressed variable bit rate video bit stream.

摘要： A reference picture is processed to generate, first, second and third pictures. The first picture has a lower resolution than the second picture and the second picture has a lower resolution than the third picture. Using independent starting positions, first and second stage field motion estimation (motion vector) searches are preformed using the first and second pictures, respectively. By performing the first stage field motion estimation search, a first field motion vector candidate is obtained. By performing the second stage field motion estimation search, a second field motion vector candidate is obtained. Using at least one of the first and second field motion vector candidates as a starting position and the third picture, a third stage field motion estimation search is performed. Alternatively, a first stage field motion estimation search is performed using the first picture to obtain a first motion vector from a top reference field and a second motion vector from a bottom reference field. A second stage field motion estimation search is performed using the second picture to obtain a third motion vector from the top reference field and a fourth motion vector from a bottom reference field. Either the first motion vector is selected and the second motion vector is deselected or the second motion vector is selected and the first motion vector is deselected. Likewise, either the third motion vector is selected and the fourth motion vector is deselected or the fourth motion vector is selected and the third motion vector is deselected. Using the selected motion vectors as starting positions and the third picture, a third stage field motion estimation search is performed.

摘要： A statistical multiplexing apparatus and method for generating and combining a plurality of encoded video bit streams. A storage device contains pre-stored a priori statistics indicative of the encoding complexity of the video signals from which the encoded video bit streams will be generated. The pre-stored a priori statistics may include inter-pixel differences in the same picture or between multiple pictures or pre-encoding a priori statistics generated during a preliminary encoding of the video signals. Examples of pre-encoding a priori statistics include the number of bits per picture at a given quantization level, an average quantization level, picture types, scene change locations and repeat field for one or more of the video bit streams. The video signals are applied to encoders which compress the signals in accordance with bit allocation decisions generated by a statistics computer. The statistics computer uses only pre-encoding a priori statistics from the storage device to generate bit allocation decisions. Alternatively, the statistics computer may use any type of a priori statistics in conjunction with a posteriori statistics received from the encoders in allocating bits. The resulting compressed video bit streams are applied to a multiplexer and combined into a single multiplexed bit stream for transmission on a single channel. The statistics computer thus has access to additional information regarding the encoding complexity of the video bit streams to be encoded and combined, and can therefore generate more accurate bit allocations and better maintain consistent video quality across multiple encoded bit streams.

摘要： Methods and apparatus for performing dual prime motion estimation on video fields or frames of a video signal. A 16.times.16 motion estimator generates a same-parity match vector M.sub.-- SP and an opposite-parity match vector M.sub.-- OP for a current macroblock of a current field using a reference macroblock from each of a previous same-parity and opposite-parity field. A dual prime motion estimator receives the M.sub.-- SP and M.sub.-- OP match vectors for the current macroblock, and generates a base motion vector MV and a delta motion vector DMV for the current macroblock. In a first embodiment, the dual prime motion estimator generates MV and DMV by setting MV equal to M.sub.-- SP and then selecting DMV such that the opposite-parity vector OPV to be computed by a decoder is as close as possible to M.sub.-- OP. In a second embodiment, OPV is set equal to M.sub.-- OP and MV and DMV are selected such that MV is as close as possible to the same-parity match vector M.sub.-- SP. In a third embodiment, the dual prime motion estimator uses error measurements between the current macroblock and the same-parity and opposite-parity macroblocks to determine whether the techniques of the first embodiment or the second embodiment should be applied to the current macroblock.
