Abstract
In a server, an image generation section stores a generated image in a frame buffer. A compression/encoding section compresses and encodes image data in units of partial images smaller than one frame. A processing order control section, on the basis of information pertaining to a scan order for a display panel connected to an image processing apparatus which is a data transmission destination, controls an order of reading out pixel data from the frame buffer, a shape of a partial image, or a compression and encoding order. The compressed and encoded partial image data is packetized by a packetization section and transmitted to the image processing apparatus by a communication section.
Claims18
An image data transfer apparatus that transfers data for a moving image to a client terminal, comprising:
- a drawing section that generates data for a frame included in the moving image and writes the data to a memory;
- a display method information obtainment section that obtains information pertaining to a scan order for a display panel connected to the client terminal;
- a compression/encoding section that reads out pixel data for the frame from the memory in an order based on the information pertaining to the scan order and compresses and encodes the pixel data;
- and
- a communication section that performs a streaming transfer of compressed and encoded frame data to the client terminal.
An image display system comprising:
- a server that transfers data for a moving image;
- and
- a client terminal that receives the data for the moving image and causes a display panel to display the data for the moving image, wherein
- the client terminal is provided with
- a display method obtainment section that obtains information pertaining to a scan order for a display panel connected to the client terminal and that transmits the information to the server, and
- the server is provided with
- a drawing section that generates data for a frame included in the moving image and writes the data to a memory,
- a display method information obtainment section that obtains information pertaining to the scan order,
- a compression/encoding section that reads out pixel data for the frame from the memory in an order based on the information pertaining to the scan order and compresses and encodes the pixel data, and
- a communication section that performs a streaming transfer of compressed and encoded frame data to the client terminal.
An image data transfer method comprising:
- by an image data transfer apparatus that transfers data for a moving image to a client terminal,
- generating data for a frame included in the moving image and writing the data to a memory;
- obtaining information pertaining to a scan order for a display panel connected to the client terminal;
- reading out pixel data for the frame from the memory in an order based on the information pertaining to the scan order and compressing and encoding the pixel data;
- and
- performing a streaming transfer of compressed and encoded frame data to the client terminal.
A non-transitory, computer-readable storage medium containing a computer program, which when executed by a computer, causes the computer to perform a data transfer process to transfer data for a moving image to a client terminal, by carrying out actions, comprising:
- generating data for a frame included in the moving image and writing the data to a memory;
- obtaining information pertaining to a scan order for a display panel connected to the client terminal;
- reading out pixel data for the frame from the memory in an order based on the information pertaining to the scan order and compressing and encoding the pixel data;
- and
- performing a streaming transfer of compressed and encoded frame data to the client terminal.
