1 Reduced Frame Quantization in Video Coding Tuukka Toivonen and Janne Heikkilä Machine Vision Group Infotech Oulu and Department of Electrical and Information Engineering P. O. Box 500, FIN-900 University of Oulu, Finland Abstract. We vary the quantization parameter in H.6 video encoding by increasing it by a well-chosen offset in every other frame, which we call reduced frames. As the motion compensation for a reduced frame is performed mainly from the previous frame (which is non-reduced), we obtain a large reduction in bit rate with only a small loss in video quality. We then develop an algorithm for the offset selection which requires only slightly more computation compared to the original encoder. Since the frame immediately preceding a non-reduced frame is reduced, advantage can be obtained by using at least two previous frames for reference. Even larger advantage can be obtained by reordering the reference picture list so that the frame, which gives the best motion compensation result, is first in the list. We also implement an algorithm for deciding the best list order. The modified encoder produces 6% smaller bit rate in average at fixed video quality at low bit rates, or up to 8% with some sequences which contain relatively little motion. Introduction Most video coding standards, including MPEG-//, H.6, H.63, and H.6/AVC [,], require hybrid encoders which first perform motion compensation by predicting picture element (pixel) values from previously encoded frames, followed by a residual transform using a discrete cosine transform (DCT) or its approximation. The transform coefficients are quantized by dividing them by a quantization parameter Q 0 and rounding them to integers. The integers are then sent to a decoder together with motion compensation information (motion vectors). The objective of video coding is to obtain optimal rate-distortion behavior, that is, given a bit rate, the quality should be as high as possible, or equivalently, for a given quality the bit rate should be as low as possible. In standards-based encoders the tradeoff between bit rate and quality is controlled with Q 0. By increasing it, the coefficients are quantized more strongly, and more of them will be zero, requiring less bits. However, the quality of the video sequence is decreased. If a frame can be accurately predicted from a previous frame with motion compensation, the transform coefficients could be quantized very coarsely, with Copyright c 006 Springer-Verlag Published in VLBV 005, scheduled for September 5-6, 005 in Costa Rei, Sardinia, Italy.

2 the result still being good. This approach is often used with bidirectionally predicted B-frames by increasing Q 0 slightly [3]. Except that being accurately predicted, there is another important reason why B-frames can be quantized coarsely without affecting much the overall quality: B-frames are not usually used in motion compensation of later frames, and therefore low quality B-frames will not decrease the quality of subsequent frames. This suggests that more common unidirectionally predicted P-frames soon after an intra-coded I-frame should be encoded with higher fidelity than P-frames just before an I-frame [], to prevent propagation of large quantization noise to many frames. Our method utilizes the same idea by adding a well-chosen constant Q to Q 0 in every other P-frame. We call these frames as reduced frames. Because the reduced frames are motion compensated mainly from the immediately preceding frame, which was encoded at full quality, the reduced frames will have only a small quality loss. In the H.6 standard, the reference frame for motion compensation can be selected. Therefore, motion compensation of non-reduced frames can be done using the previous high quality frame, avoiding the quantization error propagation from a reduced frame. In this paper we develop an algorithm for automatic selection of the quantization parameter offset Q and apply it to P-frames, thus avoiding the use of B-frames and maintaining compatibility with H.6 baseline profile. While we obtain the best advantage by using at least two previous frames for motion compensation, some improvement is achieved even with just one reference frame, making the algorithm and the technique in general useful also with older video coding standards. For H.6, we also implement an algorithm for reordering the reference picture list so that the frame, which usually gives the best motion compensation result, is first in the list. This allows using shorter codes for frame reference in the encoded bit stream, further decreasing the bit rate. Algorithm Our algorithm for the selection of Q encodes reduced frames several times. First, a frame is encoded without applying the offset ( Q = 0) with quantization parameter Q 0. As a result, the distortion D 0 and the bit rate R 0 corresponding to the case of zero offset can be calculated. In our work, we measure distortion with mean squared error (MSE) and the bit rate using average number of bits per pixel (BPP). Then, the frame is encoded again using the best offset Q b determined previously. Initially we choose Q b =. From this second pass, we get D b and R b corresponding to quantization parameter Q b = Q 0 + Q b. We need to know whether the offset improved the encoding result, and if it did, by how much. This can be accomplished by computing D b, corresponding to D b but at the bit rate R 0 instead of R b, as D b = (R 0 R b ) κ + D b ()

3 where κ is the rate-distortion curve slope at the current operational point, depending on Q 0. We describe later how it can be estimated. With this result, we compute the distortion difference of the two first passes at the same bit rate as D b = D b D 0. () The frame is encoded third time with the offset Q b+ = Q b + increased by one which produces slightly higher distortion D b+ and lower bit rate R b+. The distortion and the distortion difference are computed similarly as before: D b+ = (R 0 R b+ ) κ + D b and D b+ = D b+ D 0. After calculating D b and D b+, we know if the rate-distortion behavior improved ( D b > D b+ ) or worsened ( D b < D b+ ) by increasing the offset. By assuming that the distortion D b+ is unimodal, we continue searching the minimum by increasing or decreasing the offset until the distortion gets worse (larger) instead of better. Then, a step is taken backward to the local optimum and the frame is encoded with the final offset value. This quantization parameter corresponds to the point on the rate-distortion curve of the frame where its slope is κ. The implemented algorithm modifies Q 0 only as used in quantization. The Lagrangian multiplier λ which is used in motion estimation and macroblock mode selection [5] is derived from the original quantization parameter before the offset is added to it. Otherwise the higher quantization would decrease also motion compensation quality by favoring larger partition sizes and less accurate motion vectors. The parameter κ approximates the rate-distortion curve slope. We derived it by encoding 3 different video sequences with nine different fixed Q 0 values between 0 and 36 (see Section 3), without applying any offset. The rate-distortion curve for each sequence was then approximated by interpolating a cubic spline through the data points. The spline derivative was evaluated to obtain the curve slope at each data point. Finally a least squares estimation was used to find the optimal parameters in κ = αq0+β (3) where κ is the curve slope at quantization parameter Q 0. As a result, we obtained α = 0.35 and β = 5.70, as shown in Fig.. The parameter κ is closely related to the Lagrangian multiplier: in theory, λ = κ. In our implementation, however, we did not modify the original selection of λ, which is usually computed as λ = 0.85 (Q0 )/ Q0.3. As mentioned in Section, the encoding results can be improved significantly if at least two previous frames are available for motion compensation so that a non-reduced frame can predict from the previous non-reduced frame and if the reference picture list is reordered so that the best reference frame is first in the list. With a list containing two frames we have only two alternatives: either the pictures are swapped in the list, bringing the previous non-reduced frame first, or they are left in the encoding order. We perform the decision using the same principle as we search for the optimum quantization parameter offset: by

4 log of negative R-D curve slope Measured data points Least squares line fit Quantization parameter Fig.. Rate-distortion curve slope at various quantization parameter values and a least squares fit encoding a frame twice, with the two entries in the list swapped and not swapped. The alternative giving smaller distortion at the original rate is then chosen. We did not optimize the algorithms for speed, and if optimum offset is searched as described above, each reduced frame has to be encoded at least four times, requiring four times longer encoding time. However, there is a simple way to improve the execution time to very near the original encoder: according to our experiments (see Section 3), the optimum offset and frame order typically do not fluctuate much. Thus, they can be searched only rarely, for example after every 50 frames, while still obtaining similar encoding results but with only slightly more computation than in the original encoder. 3 Experimental results The algorithms were implemented into H.6 encoder x6 revision 39 and tested with CIF-sized (35 88) standard test sequences, listed in Table, each 50 frames long. Most H.6 quality-improving features were enabled, such as CABAC and loop filter. In the tests we used either one or two reference frames, and the sequence format was IPPP. Each sequence was encoded with nine different fixed quantization values between 0 and 36. Fig. displays the frame bit rate and PSNR for 50 consecutive frames of Paris sequence with Q 0 = 8 and Q b computed adaptively. As can be seen, although the bit rate is reduced enormously, the quality is decreased only slightly in reduced frames. Figures 3a and b display the relative bit rate reduction at constant PSNR level compared to the original encoder (at 00%, case ), for the optimum offset Available from Although x6 is very fast (real time), the coding quality is comparable to the H.6 test model JM 9.6.

Frame PSNR and bit rate versus frame number in Paris at Q 0 = 8 searched for every reduced frame (case ), and for the optimum offset searched only once in the beginning of each sequence (case ), averaged over all sequences. Fig. 3a displays the results obtained with two frames in the reference picture list, while in Fig. 3b test cases only one reference frame is made available, similarly as in older standards. Fig. 3a displays also the improvement, which is obtained by reordering the reference picture list into the best order (case 3). In the last test case, also the optimum order is searched only once in the beginning of each sequence and the same order is used for the rest of the frames. Fig. 3c displays the rate-distortion curves in the four cases for one particular test sequence, Paris, with two reference frames, and Fig. 3d displays the corresponding relative bit rates, computed from results shown in Fig. 3c.

Relative bit rate reduction in average and for one particular sequence with rate-distortion curve As can be seen in the figures, the method gives best results at low bit rates corresponding to low PSNR levels, where up to 6% decrease in bit rate is achieved with two reference frames, or up to 3.% decrease if only one reference frame is available. However, the results vary much depending on sequence. With the Waterfall sequence, even 8% reduction in bit rate is achieved. By computing the optimum offset and whether the two reference frames are swapped only once during a whole video sequence, computation demand is only about 3% higher than in the original encoder while bit rate is reduced up to 5% and 3.% with two or one reference frames, respectively. Table displays the average quantization parameter offset for each test sequence at Q 0 = 8, when the optimization algorithm was ran for every frame.

7 It also shows in how large percentage of non-reduced encoded frames the two entries in the reference list were swapped. Conclusions We observed a significant improvement in rate-distortion behavior when a wellchosen offset is added to the quantization parameter Q 0 at every other P-frame. This can be explained by noticing that while a larger Q 0 decreases significantly encoded frame size, motion compensation can still produce a frame which is near the original as it uses a higher quality frame for prediction. Based on this observation, we developed an algorithm for selecting the offset automatically. We also considered arranging reference picture list so that the high quality frames giving the best prediction are first in the list. The total bit rate is reduced in average by 6% at low bit rates, and up to 8% with some video sequences which contain only little motion. The additional computation cost is quite high, as each frame must be encoded multiple times. However, with simple modification the computation is decreased so that only around 3% more is needed compared to the original encoder while still obtaining 5% average reduction in bit rate. The method works best when at least two previously encoded frames are used for motion compensation which is generally possible only with the newest standard H.6. However, some improvement is achieved also with just one reference frame, making the method usable with older standards as well. References.
