Abstract

Disclosed are an apparatus and a method for receiving layered data transmitted over a multiple multicast channel. The layered data receiving method includes receiving the data including a count number, arranging the received data in an order of reception and storing in a jitter buffer, rearranging the data in an order of the count number and storing in a data buffer.

Claims

1. A method of receiving layered data, the method comprising:

receiving the data including a count number;

arranging the received data in an order of reception and storing in a jitter buffer;

rearranging the data in an order of the count number and storing in a data buffer.

2. The method of claim 1, wherein the rearranging of the data comprises:

assigning a rearrangement number to the count number according to a sequence of the count number in the jitter buffer;

rearranging the count number and the rearrangement number based on the count number; and

storing the data corresponding to a location of the rearrangement number of the jitter buffer in the data buffer in an order of the rearranged count number.

3. The method of claim 2, wherein the count number and the rearrangement number are rearranged through a bubblesort based on the count number.

4. The method of claim 1, further comprising:

storing a maximum count number from among count numbers included in the data in a count buffer;

receiving different data including a count number; and

storing, in the data buffer, data including a count number greater than the maximum count number after comparing the maximum count number with the count numbers of the different data.

5. An apparatus of receiving layer structured data, the apparatus comprising:

a jitter buffer to store data after arranging the data including a count number in an order of reception; and

rearranging unit to rearrange the data in an order of the count number in a data buffer.

6. The apparatus of claim 5, wherein the rearranging unit comprises:

a rearrangement number assigning unit to assign a rearrangement number to the count number according to a sequence of the count number in the jitter buffer; and

a number sorting unit to rearrange the count number and the rearrangement number base on the count number.

7. The apparatus of claim 6, wherein the number sorting unit stores the data in the data buffer using the rearrangement number in an order of the rearranged count number.
