IP camera, communication method and communication system
First Claim
1. An IP camera, comprising:
- an image capturing apparatus, capturing a plurality of consecutive images;
a video processor, coupled to the image capturing apparatus, and generating a first video stream and a second video stream according to the images simultaneously, wherein coding methods, frame rates and resolutions of the first video stream and the second video stream are different; and
a connection processor, coupled to the video processor, processing the first video stream into a first packet stream, and processing the second video stream into a second packet stream,wherein the connection processor transmits the first packet stream to a local area wireless network unit through a first wireless link, and the connection processor transmits the second packet stream to an external electronic device through a second wireless link, the coding methods, the frame rates and the resolutions of the first video stream and the second video stream are respectively determined by the video processor at least according to setting parameters from the local area wireless network unit and the external electronic device.

Abstract
An IP camera, a communication method and a communication system are provided. The IP camera includes an image capturing unit, a video processing unit and a connection processing unit. The image capturing unit captures a plurality of consecutive images. The video processing unit is coupled to the image capturing unit, and generates a first video stream and a second video stream according to the images. The connection processing unit is coupled to the video processing unit, processes the first video stream into a first packet stream, and processes the second video stream into a second packet stream. The connection processing unit transmits the first packet stream to a local area wireless network unit through a first wireless link, and the connection processing unit transmits the second packet stream to an external electronic device through a second wireless link.

5. A communication method, adapted to an IP camera, comprising:
-
capturing a plurality of consecutive images; generating at least one of a first video stream and a second video stream according to the images, wherein generating the first video stream in response to determining that a first wireless link with a local area wireless network exists, wherein only the first video stream is generated when only the first wireless link exists; and generating the second video stream in response to determining that a second wireless link with an external network exists, wherein only the second video stream is generated when only the second wireless link exists; processing the first video stream into a first packet stream when the first wireless link exists, and processing the second video stream into a second packet stream when the second wireless link exists; and transmitting the first packet stream to a local area wireless network unit through the first wireless link, and transmitting the second packet stream to an external electronic device through the second wireless link, the step of generating at least one of the first video stream and the second video stream further comprises; at least according to setting parameters from the local area wireless network unit and the external electronic device, respectively determining coding methods, frame rates and resolutions of the first video stream and the second video stream. - View Dependent Claims (6, 7, 8)
