Streaming information appliance with buffer read and write synchronization
First Claim
1. A method to handle streaming information in an information appliance having a buffer with a fixed number of storage locations, the method comprising the steps of:
- defining a logical head and tail in the buffer and a valid data area between the logical head and tail which comprises a portion of the storage locations;
writing streaming information to the logical head of the buffer with a writer module;
moving the logical head and tail through the storage locations in a first logical direction while writing the streaming information;
reading the streaming information from a first read position within the valid data area with a first reader module, wherein the first read position is temporally movable with respect to the logical head and tail; and
synchronizing the steps of writing the streaming information and reading the streaming information.

Abstract
An information appliance receives streaming information and includes a buffer, a writer module, a reader module and a synchronizer. The buffer has a plurality of storage locations, a logical head, a logical tail and a valid data area between the logical head and the logical tail. The logical head and the logical tail move sequentially through the plurality of storage locations in a first logical direction. The writer module has a write position at the logical head of the buffer. The writer module receives the streaming information and writes the streaming information to the buffer at the write position. The reader module is coupled to the buffer and has a first read position which is temporally movable with respect to the write position. The synchronizer is coupled to the writer module and the reader module and maintains the first read position within the valid data area.
