摘要:
To provide a moving image transmission device and a moving image transmission method capable of transmitting a high-quality moving image via a network even in a state where a broad band cannot be obtained as with an IP camera. Provided is a transmission device 1 which is connected with an image pickup device 3 directly or via a network and transmits a moving image to a receiving terminal 6 via a network 4, the image pickup device 3 including an image pickup unit 31 configured to pick up a moving image, an encoding unit 32 configured to perform encode processing to a picked-up moving image so as to generate the first stream data, and an output unit 33 configured to output the generated first stream data, the transmission device 1 including: a receiving unit 11 configured to receive the first stream data from the image pickup device 3; a storage unit 12 configured to store the received or generated stream data; a processing unit 13 configured to perform re-encode processing to the first stream data stored in the storage unit 12 so as to generate the compressed second stream data; and a transmitting unit 14 configured to transmit the second stream data.

A method for generating a filename for a chunk of streamed video content is disclosed. The method comprises performing a cryptographic hash function on data associated with the chunk of video content (100A)and setting the output hash value of the cryptographic hash function as the chunk filename(100B). A method for recording broadcast video content by a user device is also disclosed. The method comprises receiving a chunk of broadcast video content(310), generating a filename for the received chunk of video content (320) and storing the generated filename in a user specific storage (330). A method for broadcasting a chunk of video content is also disclosed. The method comprises generating metadata corresponding to the chunk of video content(550), the metadata comprising at least one parameter for generating a file name for the chunk of video content,and broadcasting the generated metadata with the chunk of video content(560). Also disclosed are network elements (200, 400, 600, 700) and a computer program product.

Techniques are provided for viewing windows for video streams. A video stream from a video capture device is accessed. Data that describes movement or position of a person is accessed. A viewing window is placed in the video stream based on the data that describes movement or position of the person. The viewing window is provided to a display device in accordance with the placement of the viewing window in the video stream. Motion sensors can detect motion of the person carrying the video capture device in order to dampen the motion such that the video on the remote display does not suffer from motion artifacts. Sensors can also track the eye gaze of either the person carrying the mobile video capture device or the remote display device to enable control of the spatial region of the video stream shown at the display device.

In accordance with embodiments of the present disclosure, a process for correlating a plurality of multimedia objects with a plurality of recording devices is described. The process may be implemented to generate a group label for a recording group, wherein the group label corresponds to a specific time and a specific location for the recording group. The process may include receiving, from a recording device, a join request seeking to join the recording group. The process may also include, upon approval of the join request, transmitting the group label to the recording device, wherein the group label is used by the recording device during generating of a multimedia object.
摘要:
The invention relates to a method and an apparatus for recording and streaming multimedia sequences transmitted from a data distribution device (8) over a data communications network (2), comprising receiving a recording request; receiving a multimedia sequence (DC) relating to the recording request; removing, during reception of the multimedia sequence (DC), all information comprised in the multimedia sequence (DC) except the payload data from the multimedia sequence (DC); determining an empty memory portion (MB) in a temporary memory (6a) of a control unit (6); storing, during reception of the multimedia sequence (DC), the payload data in the memory portion (MB); writing the address of the memory portion (MB) to a second networking unit memory portion (4c"); and when the memory portion (MB) is full, by means of the writing device (4d): writing the address of the memory portion (MB) to a third networking unit memory portion (4c'"), and sending a trigger signal to a file system (6f) of the control unit (6) and by means of the file system (6f) transferring the payload data stored in the full memory portion (MB) to a memory portion (MC) of a memory unit (7).
