Abstract: A content server may receive from a user device a request for a content asset and may send to the playback device a permit for accessing the content asset. The permit may be used by the content server in order to enforce a concurrency restriction, or a number of concurrent playbacks of one or more content assets desired or permitted by the playback device. In response to receiving a request for a content asset segment associated with a content asset, the content server may determine whether the number of permits currently granted to the playback device exceeds the number of desired or permitted accesses by the playback device, or a group of playback devices, to the content asset or one or more content assets. If so, then the content server may discontinue sending to the playback device any further content asset segments associated with that content asset.

Abstract: The present invention is a method for manufacturing a secondary battery. An electrode assembly and an electrolyte are accommodated into a body of a battery case. The body of the battery case has an accommodation part and a gas pocket part, and a passage that extends from the accommodation part to the outside discharges an internal gas from the accommodation part through the gas pocket part. The battery case is seated in a seating step on a support block, which has an inclined part on a side surface thereof, to support the battery case. The body is pressed to discharge a gas accommodated in the accommodation part through the gas pocket part in the battery case. This method allows easy discharging of internal gas while reducing discharge of the electrolyte with the gas.
