    Abstract: A technique for encoding pixel colour values for a full or partial digital video image frame has each different colour within the image being assigned a colour value. The most common one of the colours (0) within the frame or frame segment is identified, and runs of at least three successive pixels of that predominant colour are encoded as a first code (00) indicating a run and a second code indicating the run length (LL). Runs of successive pixels having a colour (1, 2, 3) other than the predominant colour (0) are encoded as successive iterations of a code containing only the respective colour value when the run length is less than or equal to a threshold value and as a first code indicating a run (00), a second code indicating a run length (LL), and a third code (CC) identifying the colour value when the threshold value is exceeded.

    Abstract: A portable computer device has data acceptance logic (24,40) that determines whether input data items have time and location information. If not, data items are stored together with time and location information taken from clock (30) and location determining circuitry (28), here a Global Positioning Service (GPS) system. A screen (6) is arranged to display data items in a time mode or a space mode. In the time mode, those data items with time information in a time interval are displayed on a time line. In a space mode, data items with time information in a display area are displayed, for example on a map of the display area. The display can be toggled between the time and space modes.

    Abstract: A method, and associated apparatus is described for calculating an inverse transform for transform coded data. In a main embodiment, an 8x8 Discrete Cosine Transform (DCT) (200) is arranged in columns of coefficients (202,204,206), the last coefficient is selectively modified to control mismatch in a known manner. The inverse DCT is performed selectively so as to apply abbreviated processing to groups composed entirely of zero-valued coefficients (204). For the purpose of selecting whether abbreviated processing is to be applied, a data group (206) is considered a zero-valued group if the only non-zero coefficient contained therein is a coefficient modified for mismatch control. Further the effect that the modified coefficient has on the output can be pre-calculated, said pre-calculated values being used to compensate for ignoring the non-zero coefficient.

    Abstract: Variable length decoding of DCT coefficients in MPEG video data is performed using a standard processor (400) and a small look-up table (LUT 530). The processor performs (520) an integer to floating point conversion on a portion the received bitstream (BS). By this step, lengthy codewords with many leading zeros, which are common in the codebook, are represented in a compressed form by the exponent and mantissa fields (EXP, MAN) of the floating point result (FP). The relevant bits are extracted and used as an index (IX) to address the LUT. This avoids cumbersome bit-oriented logic, while also avoiding a very large LUT that would otherwise be required to represent the same codebook. The entire LUT may thus reside in cache memory (410). In a VLIW processor implementation, decoding of one token is pipelined with the inverse scan and inverse quantisation step of the preceding token(s).

    Abstract translation: 使用标准处理器(400)和小查找表(LUT 530)来执行MPEG视频数据中的DCT系数的可变长度解码。 处理器在接收到的比特流(BS)的一部分上执行(520)整数到浮点转换。 通过这一步,具有许多前导零的冗长码字(在码本中很常见)以压缩形式由浮点结果(FP)的指数和尾数字段(EXP,MAN)表示。 相关位被提取并用作索引(IX)来寻址LUT。 这避免了繁琐的面向比特的逻辑,同时也避免了代表相同码本所需的非常大的LUT。 整个LUT因此可以驻留在高速缓冲存储器(410)中。 在VLIW处理器实现中,一个令牌的解码通过前一个令牌的逆扫描和反量化步骤来流水线化。

    Abstract: A method is described of encoding pixel color values for a digital video image frame in which each different color within the image is assigned a color value. A predominant color is identified for the image frame, runs of at least two successive pixels of the predominant color are encoded as a first code word indicating a run and a second code word indicating the run length, whereby the pixels having colors other than the predominant color are encoded as codes containing at least the respective color values of the pixels. A video image encoding apparatus comprises a processor programmed for assigning a corresponding color code to each different color in the image, whereby the programmed processor comprises means for identifying, in a data flow, runs of at least two successive pixels of the predominant color, and for encoding each such run without a code for a color value of the predominant color, each run being encoded as a first code word indicating a run and a second code word indicating the run length and means for determining, in this data flow, pixels having colors other than the predominant color, and for encoding these pixels as codes containing at least the respective color values of the pixels. In the present invention there is also suggested a video image signal display apparatus adapted for receiving and decoding an encoded video image signal generated by the above-described method.
