If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal.
If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal.
An encoded frame of the set of encoded frames is selected as a primary summary file of the multimedia file based on the comparison of the frame attribute of the at least one encoded frame with the threshold value.
As such, each video frame transcoded or padded until the encoded frame is the same size as a predicted size.
The method also comprises the step of decoding a first encoded frame of the data stream to generate an additional decoded frame.
Each random access frame is a frame encoded such that previous frames are not necessary to decode the random access frame.
If the excess sample count is determined to be greater than zero (410), X bits of the encoded frame would have a time duration greater and thus contain a greater number of samples than that of the remaining N-X bits of the encoded frame (414).
If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal.
If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal.
The method further comprises the step of outputting a first of the decoded frames before decoding of the first encoded frame is completed if the decoding step requires more time than predefined frame output time to complete.
The system also includes a stitcher module for stitching together the first encoded source and the second encoded source according to the frame locations of the graphical layout to form an encoded frame.
During transmission of the encoded video image, each available encoded frame is transmitted using different amounts or portions of the enhancement layers so as to occupy the available bandwidth.
According to the algorithm, the Q matrix for the current frame is generated based on DCT coefficient data (108) from the previous encoded frame of the same type (e.g., I, P, or B) as the current frame.
The frame encoder (fig.2) comprises a motion estimation unit (46 of fig.2), a frame head coding unit (26 of fig.2), a coded frame reconstruction and storage unit and a macroblock encoding unit (48 of fig.2).
A frame attribute of at least one encoded frame of the set of encoded frames is compared with a threshold value, which is based on the attribute for the set of encoded frames.
Calculation of the decoded frame may also be based on a description of temporal information for the second frequency band that is based on information from at least one preceding encoded frame.
A standard compression operation is then applied to the encoded frame, as well as to the metadata, in preparation for either transmission or recording.
A lost frame detector at the receiver determines if an encoded frame has been lost or corrupted in transmission, or erased.
If the encoded frame is not erased, the encoded frame is decoded by a decoder and a temporary memory is updated with the decoder's output.
A motion complexity index is updated using a quantization parameter and non-zero coefficients of the encoded frame.
