AI Technical Summary

Problems solved by technology

The memory size of the DVB receiver limits the ability to receive concurrent bursts of multiple streams
However, increasing memory size increases cost and DC power consumption, which in turn limits battery life
Limited battery life is especially a problem in handheld devices (e.g. mobile)

Abstract

An apparatus and method for receiving multiple simultaneous stream bursts comprising determining if a frame size is smaller than a size of an available memory; determining if a priority of a first packet is lower than a priority of a second packet, wherein the frame size is of a frame for the second packet; requesting to abort processing the first packet and to de-assign the available memory from the first packet if the priority of the first packet is lower than the priority of the second packet; waiting for the size of the available memory to become equal or greater than the frame size if the priority of the first packet is not lower than the priority of the second packet; and assigning the available memory to the frame for the second packet.

Description

[0001] This application is a branch of a Chinese patent application with an application date of September 06, 2008, an application number of 200880105834.1, and an invention title of "Method and Device for Receiving Multiple Concurrent Stream Bursts Using Limited DVB Receiver Memory". case application. technical field [0002] The present disclosure generally relates to apparatus and methods for receiving multiple stream bursts. More specifically, the present disclosure relates to receiving multiple concurrent stream bursts with limited DVB receiver memory. Background technique [0003] Digital Video Broadcasting (DVB) is a family of standards for digital television applications. DVB includes source coding methods (for example, to reduce the source data rate) and channel coding methods (for example, to increase transmission error tolerance) for efficient and robust digital transmission of audiovisual information such as digital television. Different DVB versions have been ...
