Method and apparatus for storing and streaming audiovisual content
A camcorder includes an input interface via which audiovisual information is received at a first rate measured in frames per second, n. A media processor coupled via a bus to the input interface receives the audiovisual information at the rate n, and transfers it to a capture buffer coupled via the bus at a second rate measured in frames per second, x, for storage. An output interface coupled via the bus to the media processor transmits the audiovisual information at a third rate measured in frames per second, y, wherein x plus y is less than or equal to n. A set of computing instructions executed on the general purpose processor in the camcorder program the media processor to transfer the audiovisual information to the capture buffer at the rate x and to transmit the audiovisual information at the rate y to the output interface.
1. A wireless camcorder comprising:
an input interface of the wireless camcorder via which audiovisual information is to be received at n frames per second;
a bus;
a capture buffer of the wireless camcorder to store at least a portion of the received audiovisual information;
a wireless output interface to transmit at least a portion of the received audiovisual information from the wireless camcorder at y frames per second;
a media processor coupled via the bus to the input interface, to the capture buffer, and to the wireless output interface;
a general purpose processor coupled to the media processor; and
a set of computing instructions executable on the general purpose processor to program or control the media processor to:
perform multiply encoding of the received audiovisual information to generate first encoded audiovisual information and second encoded audiovisual information;
transfer the first encoded audiovisual information from the media processor to the wireless output interface at a rate of y frames per second; and
transfer the second encoded audiovisual information from the media processor to the capture buffer at a rate of x frames per second, wherein the addition of x and y is less than or equal to n.
2. The wireless camcorder of claim 1 , wherein the input interface comprises a Video Graphics Array (VGA) camera and n is equal to 30.
3. The wireless camcorder of claim 2 , wherein the media processor is to transfer the second encoded audiovisual information to the capture buffer at 15 frames per second for storage therein.
4. The wireless camcorder of claim 3 , wherein the media processor is to transfer the first encoded audiovisual information to the output interface at 15 frames per second.
5. The wireless camcorder of claim 4 , wherein the output interface operates in accordance with the Bluetooth wireless technology standard.
6. The wireless camcorder of claim 1 , wherein the media processor is to transfer the second encoded audiovisual information to the capture buffer at 24 frames per second for storage therein and is to transfer the first encoded audiovisual information to the output interface at 6 frames per second, and wherein n is equal to 30 frames per second.
