Video Channel Display Method and Apparatus

A method comprising:

• retrieving a current frame of a video file;
• obtaining a reference time of the current frame based at least in part on a frame number of the current frame and a local time of a first computing device;
• decoding a first part of the current frame;
• transmitting a synchronization control information block containing the frame number and the reference time of the current frame to a second computing device to decode a second part of the current frame;
• receiving the decoded second part of the current frame from the second computing device;
• combining the decoded first part and the decoded second part of the current frame to form a decoded content of the current frame;
• and
• displaying the decoded content of the current frame.

One or more computer-readable media storing executable instructions that, when executed by a first computing device, cause the first computing device to perform acts comprising:

• receiving a synchronization control information block containing a frame number and a reference time of a current frame from a second computing device;
• selecting a frame pack having the frame number contained in the synchronization control information block as the current frame;
• decoding a first part of the current frame based on a predetermined assignment;
• sending the decoded first part of the current frame to the second computing device to form a decoded content of the current frame from a combination of the decoded first part of the current frame with a second part of the current frame decoded by the second computing device.

A system comprising:

• one or more processors;
• memory;
• a first computing module, a second computing module and a displaying module that are stored in the memory and executable by the one or more processors, wherein the first computing module is configured to:
• retrieve a current frame of a video file,
• obtain a reference time of the current frame based at least in part on a frame number of the current frame and a local time of the first computing module,
• decode a first part of the current frame, and
• transmit a synchronization control information block containing the frame number and the reference time of the current frame to the second computing module;
• the second computing module is configured to:
• receive the synchronization control information,
• select a frame pack having the frame number contained in the synchronization control information block as the current frame, and
• decode a second part of the current frame based on a predetermined assignment, the second part being different from the first part;
• the displaying module is configured to:
• combine the decoded first part and the decoded second part of the current frame to form a decoded content of the current frame, and
• display the decoded content of the current frame.
