    • A variable-length decoder system decodes a variable-length code having different code prefixes in an input bit stream. A code prefix is located in the bit stream and used to determine a number of bits to be selected from the input bit stream according to an access of a code book. Additionally, a pointer, directing access to a different code book, may also be indicated by the access of the first code book according to the located code prefix. A determination is made in this decoder system whether to perform the operation of determining a number of bits to be selected from the input stream or accessing a second code prefix table. If the code value is valid, the number of bits is selected and appended to the code prefix to form a code word which is later decoded by the system of the present invention. If another table is indicated a further code prefix is located in the input stream and the further lookup table is accessed in accordance with the further code prefix.
    • 可变长度解码器系统在输入比特流中解码具有不同码前缀的可变长度码。 代码前缀位于比特流中,并用于根据代码簿的访问来确定要从输入比特流中选择的比特数。 此外,还可以通过根据定位的代码前缀的第一代码簿的访问来指示访问不同的代码簿的指针。 在该解码器系统中确定是否执行确定要从输入流中选择的位的数量或访问第二代码前缀表的操作。 如果代码值有效,则选择位数并将其附加到代码前缀以形成随后由本发明的系统解码的代码字。 如果指示另一个表,则另外的代码前缀位于输入流中,并且根据另外的代码前缀来访问另外的查找表。

    • An audio stream is analyzed to distinguish silent periods from non-silent periods and an encoded bitstream is generated for the audio stream, wherein the silent periods are represented by one or more sets of canned encoded data corresponding to representative silent periods. In a preferred embodiment, one of the sets of canned encoded data is randomly selected for each silent period. There may be different sets of silent periods corresponding to different types of silent periods, where a particular type of silent period is selected based on some characteristic of the audio stream (e.g., energy level of the silent periods). In addition, the sets of encoded data may be generated from actual silent periods of the audio stream.
    • 分析音频流以区分静默期与非静默期,并为音频流生成编码比特流,其中无声期由与代表性静默期对应的一组或多组固定编码数据表示。 在优选实施例中,在每个静默期间随机地选择一组固定编码数据。 可以存在对应于不同类型的无声期间的不同静音期,其中基于音频流的某些特性(例如,无声期间的能量级别)来选择特定类型的无声期间。 此外,可以从音频流的实际静音时段生成编码数据组。

    • A bitstream (100) representative of at least one digital video image is decoded in real time by providing a code-book index from the bitstream (110), applying the code-book index to an index table to determine an index value (120), and comparing the index value to a first predetermined threshold (130). If the index value is greater than the predetermined threshold, then at least one current pixel is determined by copying a corresponding previous pixel into the location of at least one current pixel (140); otherwise the index value is applied to a vector table to determine at least one vector value (150) and a current pixel is determined from the vector value and a corresponding previous pixel (160). A digital video image is encoded in real time by selecting at least one pixel for encoding and determining at least one difference value between the selected pixel and at least one corresponding previous pixel (344). An index value corresponding to the location in a first table of the difference value is calculated (346). If the index value is equal to a first predetermined value then a run-length counter is incremented by a second predetermined value and the process is repeated until the index value is not equal to the first predetermined value. The run-length counter is then encoded. If the index value is not equal to the first predetermined value then the index value is encoded.
    • 代表至少一个数字视频图像的比特流(100)通过从比特流(110)提供代码簿索引来实时解码,将代码簿索引应用于索引表以确定索引值(120) ,并且将所述索引值与第一预定阈值(130)进行比较。 如果索引值大于预定阈值,则通过将对应的先前像素复制到至少一个当前像素(140)的位置来确定至少一个当前像素; 否则,将索引值应用于向量表以确定至少一个向量值(150),并且根据向量值和相应的先前像素(160)确定当前像素。 数字视频图像通过选择用于编码的至少一个像素并确定所选择的像素与至少一个对应的先前像素之间的至少一个差值(344)来实时编码。 计算与差值的第一表中的位置相对应的索引值(346)。 如果索引值等于第一预定值,则游程长度计数器增加第二预定值,并且重复处理直到索引值不等于第一预定值。 然后对游程长度计数器进行编码。 如果索引值不等于第一预定值,则编码索引值。
