Abstract
A method and apparatus for image data compression is disclosed. According to one embodiment, image data may be received at a digital video camera having an encoder and a transmitter. The encoder of the digital video camera may be used to compress the image data into an encoded information stream capable of carrying at least 8.5 frames/second in which no frame depends on a previous frame by performing intra frame encoding. The transmitter may transmit the encoded information stream from the digital video camera to a computer system via a Universal Serial Bus (USB) while consuming no more than approximately 4 Mbits/second of USB bandwidth.

A method, comprising:
- receiving image data at a digital video camera;
- an encoder of the digital video camera compressing the image data into an encoded information stream capable of carrying at least 8.5 frames/second in which no frame depends on a previous frame by performing intra frame encoding;
- and
- transmitting the encoded information stream from the digital video camera to a computer system via a Universal Serial Bus (USB) while consuming no more than approximately 4 Mbits/second of USB bandwidth.
An apparatus, comprising:
- a receiver to receive image data;
- an encoder, coupled to the receiver, to compress the image data into an encoded information stream capable of carrying at least 8.5 frames/second in which no frame depends on a previous frame by performing intra frame encoding;
- and
- a transmitter, coupled to the encoder and the receiver, to transmit the encoded information stream from the digital video camera to a computer system via a Universal Serial Bus (USB) while consuming no more than approximately 4 Mbits/second of USB bandwidth.
A system, comprising:
- a digital video camera having an encoder and a transmitter, the digital video camera to receive image data;
- the encoder to compress the image data into an encoded information stream capable of carrying at least 8.5 frames/second in which no frame depends on a previous frame by performing intra frame encoding;
- and
- the transmitter to transmit the encoded information stream from the digital video camera to a computer system via a Universal Serial Bus (USB) while consuming no more than approximately 4 Mbits/second of USB bandwidth.
