Disclosed herein are a method and a system for wireless transmission of auxiliary stream data based on a video conference system. The method comprises: connecting a first auxiliary stream device to the master of the video conference via wireless pairing; running a screening software by a second auxiliary stream device; transferring the audio and video data of the second auxiliary stream device to the master of the video conference via the screening software. The method and the system as provided herein can solve the problems which may be caused by being incompatible with audio and video interface cables, thereby improving participants' experience.

Method of recording a multimedia content broadcast streamwise, comprising the following steps: initialize a current throughput of recording of the stream in a mass memory; acquire a current portion of the multimedia content at the current recording throughput, and store it temporarily in the buffer memory; evaluate a rate of fill of the buffer memory; if the fill rate is greater than a predetermined high threshold of fill, decrease the current recording throughput; if the fill rate is less than or equal to a predetermined low threshold, increase the current recording throughput.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. Broadcaster non-real time (NRT) data packets are downloaded into RAM memory first and then saved to disk once the complete NRT package is in RAM. Old saved NRT data is retained until channel change with new NRT data, at which point old NRT data may be deleted before starting to save the new oncoming NRT data. Old NRT data may be deleted only when the new oncoming NRT data is not the same as the old.

A method of recording data received as part of a multi-channel data stream includes writing a first subset of initially-received channel segments of a multi-channel stream to corresponding main store locations instead of a write cache while writing a second subset of initially-received channel segments of the multi-channel stream to a write cache instead of corresponding main store locations. The method further provides for writing continuation segments associated with the first and second subsets of the initially-received channel segments to the write cache and flushing a collection of same-channel segments out of the write cache responsive to a determination that the same-channel segments satisfy a coalescence condition.

Multiple memory devices, such as hard drives, can be combined and logical partitions can be formed between the drives to allow a user to control regions on the drives that will be used for storing content, and also to provide redundancy of stored content in the event that one of the drives fails. Priority levels can be assigned to content recordings such that higher value content can be stored in more locations and easily accessible locations within the utilized drives. Users can control and organize how recorded content is stored between the drives such that an external drive may be removed from a first gateway device and attached to a second gateway device without losing the ability to access the recorded content from the first gateway device at a later time. In this manner, a user is provided with the ability to transport an external drive containing stored content recordings between multiple different gateway devices such that the recordings may be accessed at different locations or user premises.
