Students have asked these similar questions
How might you encode audio (or video) data in two packets so
that if one packet is lost, then the resolution is simply reduced to
what would be expected with half the bandwidth? Explain why
this is much more difficult if a JPEG-type encoding is used.
Computer Science
 There is redundancy that can occur in video that is sent over a network. Encoding techniques take advantage of two broad classes
of redundancy. Name these two encoding techniques, and how each can be used for more efficient compression.

- Audio CDs encode the music at 44,000 Hz with 16-bit samples.Would it make sense to produce higher-quality audio bysampling at 88,000 Hz with 16-bit samples? What about 44,000Hz with 24-bit samples?arrow_forwardWhen moving images are sent across a network, redundancy is inevitable. In encoding, we employ two kinds of redundancy. With regards to compression, which of the following two methods should be used?arrow_forward1. Compact discs record two channels (left and right) of music at a sampling frequency of ??=44.1kHz for each channel. If each sample is encoded with 16 bits, and one byte is 8 bits, how many bytes are required to store 48.1 seconds of music? 2. Consider a system that uses 8-bit ASCII codes to encode letters. How long (in microseconds) will it take to transmit the bit sequence encoding Hello-World! if we use a bit time of 4 samples per bit, and transmit samples at a rate of 1MHz? 3. The ASCII table below gives the ASCII codes for common alphanumeric characters and symbols listed from MSB to LSB. What is the bit sequence encoding the message 113? Assume that we transmit the codes of each character in sequence with the LSB first.arrow_forward
- The symbol £ is magnified and shown in Figure 1 with a grid superimposed. Figure 1 The image in Figure 1 is to be encoded and encrypted using the following steps: 1. Each of the five horizontal rows of the picture is encoded as a 5-bit binary number. White squares are encoded as Os and black squares as 1s. The horizontal rows are therefore encoded as: Row 1: 00110 Row 2: 01001 Row 3: 11100 Row 4: 01000 Row 5: 11110 2. Starting from the left, the first binary digit is multiplied by 16, the second by 8, the third by 4, the fourth by 2, and the fifth by 1. This will convert the 5-bit binary numbers to decimal numbers as shown below: Row 1: (0 x 16) + (0 × 8) + (1 × 4) + (1 × 2) + (0 × 1) = 0 + 0 +4+2+0 = 6. Row 2: (0 x 16) + (1 × 8) + (0 × 4) + (0 × 2) + (1 × 1) = 0 + 8 +0+0+1 = 9. Row 3: (1 x 16) + (1 × 8) + (1 × 4) + (0 × 2) + (0 × 1) = 16+8+4 + 0 + 0 = 28. Row 4: (0 x 16) + (1 × 8) + (0 × 4) + (0 × 2) + (0 × 1) = 0 + 8 +0+0+0= 8. Row 5: (1 x 16) + (1 × 8) + (1 × 4) + (1 × 2) + (0 × 1)…arrow_forwardThe type of encoding in which manipulation of bit streams without regard to what the bits mean is ..................... a.

- a. Huffman coding assigns codes to characters such that the length of the code depends on the relative frequency or weight of the corresponding character. Thus, it is a variable-length code. If the estimated frequencies for letters match the actual frequency found in an encoded message, then the length of that message will typically be less than if a fixed-length code had been used. Due to such advantages, RadiantRay Networking Sdn Bhd uses Huffman compression technique to encode the message before transmitting over the network to its customer. Suppose the message contains the following strings "a fast runner never be afraid of dark“ a. How many bits may be required for encoding the message without using Huffman coding? b.
